Retool built the internal-tools category, but its per-builder pricing, closed-source code, and self-hosting complexity send plenty of teams looking for something else.
If you're hitting those walls, Appsmith leads for open-source developers, ToolJet for AI-native building, and Superblocks for governed enterprise apps.
I tested the leading Retool alternatives and shortlisted the 9 best across pricing at scale, code ownership, self-hosting, AI building, and governance. Here's the ranked list, honest pricing, and who each is built for.
9 best Retool alternatives: TL;DR
- Appsmith: Best open-source, developer-first alternative.
- ToolJet: Best for AI-native building with per-builder-only pricing.
- Superblocks: Best for governed enterprise internal apps.
- Budibase: Best for small teams that want free self-hosting.
- Bubble: Best for customer-facing web and mobile apps.
- Microsoft Power Apps: Best for Microsoft-stack shops.
- Glide: Best for spreadsheet-to-app builds.
- UI Bakery: Best for cheaper Retool-style building at scale.
- WeWeb: Best for custom front-ends over an existing backend.
Why look for Retool alternatives?
Retool is a capable platform, and for engineering teams with the budget, it works well. It supports app generation from prompts, agents, and a deep component library. Still, five recurring pain points push teams to look elsewhere.
- Pricing that compounds: Retool charges per builder and separately per end user, so a widely used internal tool adds end-user cost on top of builder seats. Business runs at $50 per builder monthly on an annual billing plan, and SSO sits behind that tier.
- Limited code extensibility: The component library is broad, but customization is shallow, with styling limited to inline CSS or JavaScript. Users report building too many custom components from scratch.
- Closed-source code: Retool's codebase is entirely closed, so your security team can't audit it the way they can with open-source platforms. Apps also can't be exported as code, which locks you in.
- Self-hosting complexity: A full on-premises deployment is challenging to set up and costly to keep running, since you own the infrastructure and operations.
- Uneven observability coverage: Retool ships native log forwarding for Datadog and Splunk, but New Relic requires custom container log setup, and event-driven streaming relies on Kafka as the primary supported broker.
Which Retool alternative should you choose?
Here's the quick version before the deep dives.
- Choose Appsmith if you want open-source transparency and free self-hosting, though non-engineers will find its JavaScript-everything approach a barrier.
- Choose ToolJet if you want open-source, per-builder-only pricing, and a first-class AI agent layer; it's less ideal if you want a large template library.
- Choose Superblocks if you need governed enterprise apps with code export, though it's focused on internal tools with customer-facing products outside its scope.
- Choose Budibase if you're a small team wanting free self-hosting, or if it's less suited to complex custom logic.
- Choose Bubble if you're building customer-facing web or mobile apps, though its workload-unit pricing can get unpredictable.
- Choose Microsoft Power Apps if you're already invested in the Microsoft 365 and Azure stack, though value drops sharply outside it.
- Choose Glide if your data already lives in spreadsheets and you want mobile-responsive apps fast, though complex logic will push you elsewhere.
- Choose UI Bakery if you want Retool's model at a lower cost, with Python support, though its community is smaller than that of the open-source leaders.
- Choose WeWeb if you already run a backend and want a polished custom front end, though you'll need the backend separately.
- Stick with Retool if you're an engineering team with a budget that needs a mature component library and native mobile apps, and per-user cost isn't a constraint

How to evaluate Retool alternatives
The right choice comes down to matching a platform to your real constraints. Five questions to work through:
- Who is building? Some tools need developers fluent in JavaScript; others let business users build with AI or visually. Be honest about who will keep your apps running day-to-day.
- Do you need code ownership? If avoiding lock-in matters, prioritize platforms that let you export standard code or self-host, so the code stays yours.
- How does pricing scale? Per-builder-plus-per-end-user models get expensive fast. Model your cost based on real user counts, including end users alongside builder seats.
- Open-source or managed? Open source gives you transparency, free self-hosting, and ownership of operations. Managed platforms trade that control for less operational overhead.
- What governance do you need? Regulated teams need RBAC, audit logs, SSO, and deployment control in the base tier, so you don't pay extra for compliance essentials.
Stop overpaying for internal tools
Retool defined this category, but its pricing model and closed platform push many teams toward alternatives that fit how they work in practice. The open-source options win on transparency and cost, while managed platforms compete on AI building and governance.
If you need governed enterprise apps built with AI, visual tools, or code that you can modify, extend, or host anywhere, Superblocks is worth a look.

Frequently asked questions
What is the best Retool alternative?
The best Retool alternative depends on your use case. Appsmith leads for open-source developers, ToolJet for AI-native building, and Superblocks for governed enterprise apps. Most teams pick based on code ownership, pricing, and who's building.
Is there a free alternative to Retool?
Yes, several Retool alternatives are free to self-host. Appsmith and ToolJet are open-source and free to self-host with unlimited users, and Budibase is free for up to 20 self-hosted users. These avoid Retool's per-builder pricing entirely if you can handle hosting.
Why do teams switch from Retool?
Teams switch from Retool primarily due to cost and lock-in. Its per-builder-plus-per-end-user pricing compounds as adoption grows; SSO sits behind the Business tier; the code is closed-source; and apps can't be exported, so teams look for cheaper, more open options.
What is the best open-source Retool alternative?
The best open-source Retool alternative is Appsmith for developer-first control, or ToolJet for AI-native building with per-builder-only pricing. Both are free to self-host with full code transparency, letting security teams audit the codebase Retool keeps closed.
Which Retool alternative is best for enterprises?
The best Retool alternative for enterprises is one with built-in governance. Superblocks fit enterprises needing RBAC, audit logs, and hybrid deployment with code export, while Microsoft Power Apps suits Microsoft-centric organizations already running Azure and 365.
