Introduction to Retool and Appsmith
Appsmith and Retool are low-code platforms that enable businesses to build custom internal software, without the overhead of do-it-yourself (DIY) development. These platforms offer drag-and-drop interfaces for building application UIs and out-of-the-box integrations with databases and SaaS platforms. Using these platforms, developers can build and iterate on internal tools much more efficiently than DIY app development.
While Appsmith and Retool address similar business challenges, each platform has its unique advantages and drawbacks, which are covered in detail below. Notably, Appsmith is an open-source offering based in India focused primarily on internal web applications, while Retool is San Francisco-based and offers a wider swath of platform capabilities including web apps, automated workflows, mobile applications, and a hosted database.
In this article, we'll dive into Appsmith and Retool to help you understand the benefits and drawbacks of each platform and identify the best fit for your business.
The benefits of internal tooling platforms
Most businesses have a variety of internal processes that rely on spreadsheets or email. As operational complexity increases, these processes become outdated or fall out of compliance, inhibiting teams from best serving their customers.
Business build custom internal software to manage this operational complexity, enabling teams to better serve customers and successfully scale their business. However, building and maintaining these tools from scratch is expensive and time-consuming, requiring frontend, backend, and infrastructure engineering expertise.
Internal tooling platforms like Appsmith, Retool, and Superblocks enable higher development velocity for organizations, protecting engineering resources and resulting in better software for operations teams.
Internal tooling platform evaluation criteria
We've compiled the common set of decision criteria used to select a low-code internal tooling platform, based on several customer evaluations in the space:
Easy to use: Low-code platforms must be easy to use and intuitive to ensure adoption across users of varying technical expertise. These tools must enable developers to quickly build applications and streamline workflows
Scalable and performant: Enterprises are building mission-critical apps, so these apps must be scalable and performant with high data volumes and intensive processing
Extensible with code: Organizations have unique needs and the ability to implement custom logic and extend the app builder with custom code in a language of their choice is necessary for a future-proofed solution to avoid being blocked on the platform’s out-of-the-box capabilities
Cost-effective to self-host: Mission-critical apps interact with production databases and other sensitive data, making it a requirement that data does not leave their VPC. A vendor must offer this functionality without significant additional overhead to avoid bloating the total cost of ownership
Cutting-edge AI: Enterprises want to work with modern and innovative vendors incorporating the best technologies. AI is crucial for accelerating software development and empowering organizations to deliver quickly and efficiently
Exceptional support: Enterprises require that bugs, issues, and feature requests are handled in a timely manner and that their requests are resolved quickly to not block any of their business activities and impede development of mission-critical apps
Monitoring and observability: Enterprises need to monitor the software they build with low-code platforms using their observability vendors like Datadog and New Relic so they can detect errors and ensure software quality remains high
Real-time streaming: Enterprises must provide ops teams real-time data and insights for optimal decision-making, so platforms need to support building on top of streaming platforms like Kafka, Kinesis, Confluent, and OpenAI
Keep reading to see how Appsmith and Retool stack up against this evaluation criteria.
Appsmith is an open-source low-code platform that allows developers to build internal dashboards and applications. Appsmith provides a library of drag-and-drop components to craft app UIs, and integrates with various databases, APIs, and third-party services, making it capable of addressing a variety of use cases.
Benefits and key features of Appsmith
The Appsmith platform offers several key features and benefits to businesses, many of which are a result of its open-source nature.
Open source and transparent: Developers can access and inspect the entirety of the Appsmith codebase to dive deeper into how it works and have confidence that there are no backdoors or security vulnerabilities for transparency and trust. They can also contribute back to the platform

Per end-user pricing model: Appsmith’s usage-based pricing is based on end-users of applications, so businesses do not pay for seats for developers who build applications in Appsmith
Drawbacks of Appsmith
The Appsmith platform is suitable for organizations looking for a low-code platform who strongly prefer open-source, and are willing to make sacrifices on performance, extensibility, and support. When evaluating Appsmith, some key drawbacks for consideration are:
No Workflows & Scheduled Jobs: Appsmith does not have a workflow offering, so businesses would need to contract with another vendor to handle programmatic workflows
Legacy on-premise deployment for self-hosting: Keeping customer data in your network using Appsmith requires deploying the entire Appsmith platform on-prem. This deployment model results in high ownership costs due to dedicated infra, DevOps, and downtime for upgrades
No US-Based Support: Appsmith is based in India and does not have US-based support, which is often crucial to US-based enterprises
Retool is a San Francisco-based internal tooling vendor founded in 2017. Retool offers a low-code platform made up of several different offerings including:
Web apps: Retool’s classic offering, used for creating internal web applications such as graphical user interfaces (GUIs) for databases and admin dashboards. This product is most similar to Appsmith’s offering
Workflows: A UI builder for automating custom logic to replace on-off scripts and cron jobs
Mobile apps: A low-code builder for native iOS and Android apps
External apps: The ability to embed Retool apps in external websites and hook into external authentication systems
Database: A managed Postgres database that can be edited via a spreadsheet-like user interface
Benefits and key features of Retool
Overall, Retool is a traditional vendor that’s suited for organizations that don’t want to invest in an open-source offering. Retool is a common choice for businesses looking for an enterprise-focused US-based vendor to build internal apps. Some key benefits of Retool include:
Drag-and-drop editor: Retool’s drag-and-drop editor makes it easy for developers without frontend expertise to build UIs
