Limitations of Retool

Despite the company’s early entry to the internal tooling market, Retool has a number of shortcomings which should be well understood by prospects and customers. These limitations, as of January 2024, include:

  • Limited extensibility with code: Retool's limited extensibility in code - including lack of language support beyond JavaScript in applications as well as limited support for writing custom components - poses potential roadblocks for developers.
  • Lackluster performance: Retool apps often suffer from poor performance due to browser-based code execution, single-step queries, and the lack of global edge caching.
  • High cost of ownership when self-hosting: Retool's legacy on-premise deployment is resource-intensive and complex, impeding businesses from accessing new features and security fixes and increasing total cost of ownership for enterprises with stringent data security requirements.
  • No streaming support: Retool does not support event-driven architectures like Kafka, Confluent, or Kinesis, preventing businesses from building real-time streaming apps. As a result, operations teams cannot benefit from real-time insights and CTOs cannot use Retool to maximize ROI on streaming technologies.
  • Lack of observability: Retool does not have native integrations with observability platforms like Datadog, Splunk, or New Relic in apps, preventing developers from easily detecting errors and viewing logs alongside other production monitoring.
  • Slow feature rollouts for on-premise: There are often significant delays before new features are made available in self-hosted Retool versions, hindering businesses wanting to leverage new technologies in their internal tooling with their preferred deployment model.
  • Closed source code: Retool's closed source code prevents code audits by security teams and does not allow for extensibility.
  • Flowchart-based Workflows UX: Retool employs a flowchart canvas for its Workflow UI, which quickly becomes unwieldy as logical complexity increases, making the logic challenging to understand, iterate on, and debug.
  • Security breach in August 2023: Retool had a significant data breach in August 2023, with many customers’ accounts being compromised, resulting in leakage of sensitive data and reported losses of up to $15MM for a single customer.

Read more about each of these shortcomings below to better understand why many companies are considering alternatives to Retool.

Of the many alternatives to Retool in 2024, Superblocks is the superior option, besting competitors with its robust feature set, generative AI capabilities, extensibility with code, self-hosted agent architecture, and optimization for enterprise security and scale for mission critical applications. Appsmith, UI Bakery, DronaHQ and Internal.io are also strong alternatives to Retool, especially within the SMB segment, each with its own set of strengths and weaknesses, as covered in detail in this article.

For a feature-by-feature comparison of each vendor, see the matrix included below.

Speak to a Superblocks expert

1. Superblocks

Superblocks is an enterprise ready low-code without limits platform for building custom internal applications, automated workflows, and scheduled jobs. Developers can extend Superblocks infinitely with code, build faster with an AI Copilot, self-host without the overhead, and deliver performant apps at scale, all while adopting affordably across their organization.

Strengths
Infinite Extensibility with Code: Superblocks is infinitely extensible with code, allowing developers to write complex backend APIs with NodeJS and Python, leverage Javascript on the front-end, and build custom components with React within their own IDE and filesystem.
Architected for Enterprise Scale & Performance: Superblocks application front-ends are multi-threaded for smooth UI rendering, while back-end queries scale elastically with on-demand cloud compute - critical for the enterprise.
Generative AI Native: The context-aware Superblocks AI Copilot supercharges development, with support to generate, explain, and debug SQL, JavaScript, Python, JSON, and HTML, as well as integrate with REST APIs.
Self-Hosted Agent Architecture: The Superblocks On-Premise Agent is lightweight, stateless, simple to deploy, and new App Builder features are instantly available from the cloud, while ensuring that customer data never leaves your network.
Production Monitoring & Observability: Superblocks integrates with observability providers like Datadog, Splunk and New Relic, so you can view metrics, traces, and logs within your preferred provider.
Real-Time Streaming Apps: Superblocks natively supports event-driven architectures like Kafka, Confluent, and Kinesis, enabling developers to operationalize real-time insights without any streaming expertise.
Weaknesses
Newer Entrant: Superblocks was founded in 2021. However, Superblocks has seen rapid growth, having raised $37,000,000 in a Series A round led by Kleiner Perkins.
No Support for Native Mobile Apps: Superblocks does not support building native mobile applications for iOS or Android. However, Superblocks does support building mobile-responsive web applications.
User Analytics in Private Beta: The ability to view user analytics for usage of your applications, such as number of views, time spent in an app, and more is currently in private beta, as of January 2024.
No Air-Gapped Deployments: Superblocks does not support an air-gapped deployment model, as businesses self-host Superblocks with an agent architecture rather than a legacy on-premise model.

Conclusion: Superblocks is the #1 alternative to Retool and the only vendor offering a fully-featured low-code internal tooling platform without limits. Some notable benefits of Superblocks compared to Retool include:

  • Greater Extensibility with Code: Retool apps support client-side JS only, while Superblocks supports React, JS, Node, & Python. Retool Custom Components rely on one HTML file, with web-based imports limited to an iframe, while Superblocks provides full extensibility with React.
  • Scalable Architecture & Better Performance: Application front-ends in Superblocks are multi-threaded for smooth UI rendering, while back-end queries scale elastically with on-demand cloud compute. Retool JS queries are executed in the browser, and thus limited by browser CPU & memory, causing major latency for large apps.
  • Drastically Less Overhead When Self-Hosting: Superblocks offers a lightweight, stateless On-Premise Agent, which is simple to deploy and provides access to new App Builder features instantly from the cloud. Self-hosted Retool is a legacy on-premise deployment, requiring dedicated infrastructure and heavy DevOps upgrades with downtime to access any bug fix or new feature.
  • Support for Real-Time Streaming Apps: Superblocks integrates natively with streaming platforms like Kafka, Kinesis, Confluent, OpenAI, making it easy to build apps for real-time fraud alerting, live gameplay dashboards, best-in-class AI chatbots, and more. Retool lacks native support for streaming, preventing organizations from harnessing real-time insights.
  • Production Monitoring & Observability: Superblocks integrates with observability providers like Datadog, Splunk and New Relic, providing visibility into metrics, traces, and logs from internal tools within your preferred provider. Retool does not have observability, leaving you blind when errors arise.
  • Lower total cost of ownership: Self-hosting Retool comes with platform and add-on fees, and infrastructure, DevOps, and downtime costs - none of which apply when self-hosting Superblocks.
Compare Superblocks vs Retool head-to-head

2. Appsmith

The second place Retool alternative is Appsmith, an India-based open source internal tooling platform. Appsmith provides feature parity with much of the Retool application builder, though it notably does not support automated workflows or scheduled jobs. Appsmith has a growing developer community on Github and provides both a cloud and fully on-premise deployment that can be air-gapped.

Strengths
Open Source: Developers can audit the entire Appsmith codebase, and contribute to the Appsmith platform.
Community on Github: The Appsmith repository has ~28k Github stars and over 200 contributors.
Styling Customization in App Builder: Appsmith enables developers to customize the styling of components by exposing a variety of styling properties for most components.
Source Control with Git: Appsmith offers Git-based source control via integrations with GitHub, GitLab, & Bitbucket, allowing businesses to manage app versions directly in their preferred Git provider.
Weaknesses
No Backend APIs: Any code written on Appsmith is executed in the browser; developers cannot write backend APIs, which results in limited extensibility and degraded performance.
No Workflows & Scheduled Jobs: Appsmith does not have a workflows offering, so businesses would need to contract with another vendor to handle programmatic workflows.
Limited Extensibility with Code: Appsmith only supports client-side JavaScript, limiting developers' ability to extend the platform with custom logic and functionality.
No US-Based Support: Appsmith is based in India and does not have US-based support, which is often critical to US-based enterprises.

Conclusion: Appsmith is a good alternative to Retool for building internal applications, especially if a business strongly prefers a fully open-source vendor. However, Appsmith does not offer support for automated workflows or scheduled jobs; without workflows or multi-step backend application APIs, Appsmith does not provide fast query performance when working with large data sets or complex business logic, making it unsuitable for mission-critical business applications in the enterprise.

3. UI Bakery

UI Bakery lands in third place, offering a less expensive alternative to Retool intended primarily for small and midsize businesses. UI Bakery includes an application builder as well as support for workflows and scheduled jobs. UI Bakery supports multi-step application APIs, enabling businesses to build out complex business logic. The UI Bakery team is based in Lithuania and is comprised of ~10 employees.

Strengths
Less Expensive at Scale: UI Bakery’s pricing is reasonably affordable at scale, with their premium offering being priced at a flat rate of $249/month plus $19 for each additional user after the first 10.
Workflows & Scheduled Jobs: UI Bakery offers a workflow builder with a sequential step interface that is simple to use. These workflows are available as part of the self-hosted & cloud offerings.
Multi-Step APIs: Developers can build APIs which run multiple steps, minimizing overhead and making program logic easier to understand and debug.
Python Support: UI Bakery supports Python which runs on the server-side, providing greater flexibility to developers.
Weaknesses
No Deployment Control and Previews: UI Bakery does not offer support to preview changes made to apps via a shareable URL, commit those changes and view previews for historical commits, or deploy commits. The only option in UI Bakery is to deploy the working version.
No AI Copilot: UI Bakery does not offer a built-in AI Copilot, preventing developers from easily leveraging AI when building applications.
Company Size: UI Bakery currently has ~10 employees on Linkedin and no publicly available funding information.
No US-Based Support: UI Bakery’s team is based in Lithuania and does not have US-based support, which is often critical to US-based enterprises.

Conclusion: UI Bakery is suitable for smaller businesses looking for a lower-cost alternative to Retool. Unlike Retool’s equivalent offerings, UI Bakery’s Workflow & Scheduled Jobs offerings are available to both Cloud and On-Premise customers. UI Bakery’s lack of deployment control, SCIM support, and US-based support make UI Bakery less suitable for enterprises than Retool; however, UI Bakery does offer some of the same capabilities, and thus may be sufficient for less complex use cases, at a lower price tag.

4. DronaHQ

DronaHQ comes in fourth place, as another India-based player in the internal tooling space, offering a narrower feature set at a lower cost. DronaHQ provides an application builder with a wide variety of built-in components, as well as a Workflow & Scheduled Job builder. DronaHQ’s pricing model does not distinguish between developers and end-users, charging a flat rate for all users.

Strengths
Low Price Per Developer: DronaHQ is cheaper than alternatives on a per-developer basis, since their pricing is a flat fee per user and does not distinguish between developers and end-users.
Workflows & Scheduled Jobs: DronaHQ offers support for automated workflows & scheduled jobs.
Vast Component Library: DronaHQ boasts over 150 built-in components, with many long-tail components supported out of the box.
Native Mobile Apps: DronaHQs provides a dedicated offering for building native mobile apps.
Weaknesses
Less Intuitive UX: DronaHQ is more difficult to use than Retool, with a less organized properties panel and unintuitively named settings.
Limited Deployment Control and Previews: DronaHQ does not offer deployment control with commits and previews. Previewing changes in DronaHQ requires publishing to a dedicated environment.
No SCIM: DronaHQ does not support the SCIM standard for managing users and groups via an external user directory.
Inflexible Per User Pricing: DronaHQ’s flat rate per user does not distinguish between developers and viewers of tools, resulting in a higher bill for organizations with many viewers of internal tools.

Conclusion: DronaHQ is another alternative internal tooling platform which provides an application builder as well as support for automated workflows and scheduled jobs. DronaHQ has some notable feature gaps compared to Retool, and is generally less user-friendly. DronaHQ’s pricing model does not distinguish between developers and end-users; however, their per-user cost is relatively low compared to Retool, so for organizations with more developers than end-users, DronaHQ may be a cost effective option.

5. Internal.io

Rounding out the list in fifth place is Internal.io, a San Francisco-based Retool alternative focused primarily on non-developers. Internal.io offers an application builder as well as support for scheduled jobs, and allows users to build multi-step APIs via their Pipelines feature; however, these Pipelines cannot be invoked over HTTP, preventing them from being used as webhooks or REST APIs. Internal’s pricing model is per-user, with a single flat rate for all users.

Strengths
Multi-Step APIs: Developers can leverage Internal’s Pipelines feature to build multi-step business logic which can be invoked within applications.
Scheduled Jobs: Internal supports invoking automated workflows on a schedule via their Automations feature.
Source Control with Git: Internal supports Git-based source control via an integration with GitHub.
Queues for Business Process Automation: Internal offers a dedicated Queues feature, intended for managing and executing BPA-style tasks.
Weaknesses
Expensive, Inflexible Per User Pricing: Internal charges a flat rate for all users, making it expensive for large organizations with high volumes of users viewing and interacting with internal tools.
Cannot Invoke Workflows over HTTP: Though Internal does offer support to build automated workflows, these workflows can only be invoked on a schedule, not over HTTP as API endpoints or webhooks.
Limited Extensibility in Code: Internal supports only client-side JavaScript; developers cannot write Python code or build custom components in HTML or JavaScript.
No AI Capabilities: Internal offers no AI capabilities, lacking an AI copilot for developers as well as a native integration with OpenAI.

Conclusion: Internal.io provides similar functionality to Retool within their application builder and scheduled job offerings. Internal.io’s pricing model is less flexible than Retool’s, as it does not distinguish between builders and viewers of internal tools; thus, Internal.io is likely to be very expensive to roll out across organizations. Additionally, Internal’s automated workflows can only be invoked on a schedule, not over HTTP, preventing them from being used as webhook handlers or API endpoints. Internal emphasizes no-code, especially within their application builder, so it may be a suitable alternative to Retool for businesses with less development resources.

Why Look for Alternatives to Retool?

1. Limited extensibility with code

While Retool promotes itself as developer-friendly, it lacks essential features needed for comprehensive code extensibility, exposing developers to potential roadblocks when functionality is not supported. Key limitations include:

  • JavaScript Only Application Queries: Application queries in Retool are JavaScript only; other common languages such as Python are not supported.
  • Limited Support for Custom Components: Retool’s Custom Components offering is limited, as discussed in more detail below.

Retool’s Custom Components offering allows developers to bring custom UI components to Retool Applications. However, in practice, this offering comes with significant limitations:

  • Styles Limited to Iframe: Styles are limited to the iframe, making it impossible to build custom modals, slideouts, and popovers.
  • Separate Sandbox Per Component: Each Retool custom component is a separate sandbox, limiting developers ability to write shared code, such as sharing state across components (ex: Redux); each component's state must be independently managed, resulting in degraded performance and scalability, and complicating application-wide consistency.
  • Poor Developer Experience: Retool’s Custom Components are authored within a single HTML within the browser, preventing developers from bundling multiple files. Developers can write React code by inserting a script tag, but the development experience is hacky and ignores best practices.
  • Dependencies Must Be Bundled for Use on the Web: Third-party libraries must be bundled for use on the web to be available for use in Retool Custom Components, impeding access to the NPM ecosystem and local packages. Reusing existing libraries is cumbersome, necessitating maintenance of packages on a CDN, with an undesirable alternative of copying existing code directly into each Retool component HTML file.
  • Performance Impact of Importing Packages on the Web: Libraries imported via script tags cannot use module bundlers like Webpack or Rollup, eliminating advantages like tree shaking, code splitting, and transpilation. This approach forces Retool to load entire libraries, negatively impacting performance.
  • Unable to Extend Built-in Components: Developers cannot easily extend built-in components, which means any custom component must be built entirely from scratch.

2. Lackluster performance

Businesses leveraging Retool often complain about poor performance within Retool apps. Retool’s performance issues can be attributed to a few notable architectural shortcomings:

  • Browser-Based Code Execution: All Retool application queries written in Javascript are executed in the browser. This architecture restricts processing capacity to the browser's CPU and memory, unlike traditional server-based applications that can manage query loads and scale as needed.
  • Single-Step Queries: Application queries in Retool run as single steps, which means that data from each query must be returned to the browser for any subsequent processing; this architecture results in excess network requests and data traffic.
  • Lack of Global Edge Caching: Retool does not utilize global edge caching. As a result, each time a user accesses an application, the tool definitions must be fetched from Retool's servers (or a business's own servers if deploying Retool on-premise), increasing loading times and negatively impacting application performance.

3. Self-hosting costs and overhead

Many businesses must ensure sensitive data stays within their network to meet security and compliance requirements. To satisfy these requirements, businesses must self-host Retool. Self-hosted Retool is a resource-intensive legacy on-premise deployment with infrastructure, DevOps, and downtime costs. Moreover, if a business operates across multiple data regions or uses several cloud providers, they must deploy unique Retool instances in each virtual private cloud (VPC), multiplying complexity.

Furthermore, in order to access new features or security patches, Retool’s deployment model requires that businesses perform exhaustive upgrades; this requirement not only extends the period during which the platform is outdated, but also exposes businesses to avoidable security threats and hampers their agility in responding to shifting market needs.

The overall complexity of deploying Retool on-premise means businesses will often need to reallocate resources from shipping internal tools to maintaining their Retool infrastructure.

4. Expensive software & platform fees

Retool's enterprise tier may only be available to self-host at a fixed platform fee with a set number of users, rather than based on usage. Additionally, some features may be only available to purchase as add-ons to the Enterprise package, driving up the average cost per user.

For more information, read this deep dive on Retool's pricing.

5. No streaming support

Retool does not offer native support to integrate with event-driven streaming platforms like Kafka, Kinesis, and Confluent. Without native support for event-driven architectures, businesses cannot easily build apps on top of these core infrastructure providers. Users are thus limited to batch updates and cannot get real-time insights from apps built with Retool.

6. Lack of observability in apps

Retool apps do not integrate with observability providers like Datadog, New Relic, or Splunk. Without these integrations, developers cannot easily debug Retool apps, view logs, or receive proactive notifications when errors arise in mission-critical internal apps.

7. Slow feature rollout for self-hosted

Retool is often slow to roll out new features to customers self-hosting Retool. Features are commonly available in cloud-hosted Retool for multiple months before they are made available in a self-hosted version, as evidenced by their changelog.

Once a feature is made available as part of a self-hosted Retool version, DevOps teams must undertake the arduous upgrade process of their deployment, resulting in further delays before new features and bug fixes are available to users.

8. Closed Source Code

Retool is completely closed source, which comes with significant downside. First, code cannot be audited by security teams. This opaque, potentially buggy and vulnerable code has access to production databases and, when self-hosting Retool, is running entirely inside a business’s network; thus, there are limited preventative measures a business can take to mitigate the risk of exposing a business’s VPC to vulnerabilities and unintentionally impacting production databases. Additionally, the closed source nature of Retool means that the platform is inherently less extensible; businesses must wait for Retool to implement new features, slowing pace of development compared to open-source offerings.

9. Flowchart-based Workflows UX

Developers build automations in Retool Workflows using a flowchart-style UI. While this approach is common amongst low-code workflow automation tools, it quickly becomes difficult to parse the logical flow as the number of nodes and paths expands with complexity. As a result, workflows built on Retool are difficult to maintain and debug for enterprise use cases.

10. Security breach in 2023

Retool had a significant data breach in August 2023, during which many customers’ accounts being compromised. Since businesses run mission-critical software on Retool, hackers obtained access to sensitive data, resulting in reported losses of up to $15MM for a single customer.
