9 Best Retool Alternatives for Those Looking for More Options

The best Retool alternative depends on what you want to change.

Appsmith is a strong open-source option, ToolJet offers flexible internal-tool development, Budibase combines low-code building with a built-in database (DB), and Modelence is better suited to teams that want to build and own a full-stack application.

This guide compares nine Retool alternatives across cost, deployment, code ownership, self-hosting, and development approach so you can narrow the list based on your team’s priorities rather than features alone.

Why Teams and App Builders Look for Retool Alternatives

Retool is a capable platform for building internal tools quickly, but its trade-offs can become more noticeable as teams grow and applications become more complex.

Common reasons teams look for alternatives include:

• Pricing: Costs can increase as more builders, internal users, or external users need access.
• Customization and lock-in: Teams that want more control over the application layer may prefer open-source or code-first options.
• Feature limits and learning curve: Retool speeds up standard internal-tool development, but highly customized workflows or interfaces can require more effort.
• Security and self-hosting: Retool supports enterprise security, including System and Organization Controls 2 Type II (SOC 2 Type II) controls and self-hosting, but some advanced capabilities are tied to higher-tier plans.

Retool can still be a strong fit for teams with the budget and engineering resources to support it. The question is whether its pricing, flexibility, and deployment model still match the team’s needs as usage grows.

How We Evaluated These Retool Alternatives

We evaluated these Retool alternatives against the trade-offs that matter most as teams scale.

That includes the true 12-month cost for a 10-person or 50-person team, including per-seat, usage-based, and overage charges where applicable. We also considered code ownership and portability, plus whether each platform supports self-hosting or specific data-residency needs.

We also looked at how each platform uses AI assistance and how far it can stretch beyond its default component library when teams need more complex logic or user interface (UI).

No single Retool competitor wins in every dimension.

The best Retool alternative depends on team size, technical depth, compliance requirements, and whether you need a widget builder or a more complete application platform.

Considerations for Choosing the Right Retool Alternative

Start with the reason you are leaving Retool rather than comparing feature lists.

• Per-user cost: Consider Appsmith for an open-source option or ToolJet if avoiding end-user fees is important.
• Built-in DB: Budibase combines its visual builder with its own DB, reducing setup for simpler internal apps.
• Code-first workflows: Windmill is built around scripts, workflows, and apps rather than a primarily drag-and-drop approach.
• Enterprise governance: Superblocks supports code export and a lightweight on-premise agent for teams with stricter data residency requirements.
• Managed low-code: UI Bakery or DronaHQ are worth comparing if you want a Retool-like experience without managing the platform yourself.
• Code ownership: Refine provides React code, while Modelence generates full-stack applications whose code can be exported and deployed elsewhere.

Also consider vendor lock-in before switching.

Retool apps can be exported in Retool-specific formats, but not as standalone React or HyperText Markup Language (HTML) applications, so moving to a different platform generally means rebuilding or porting the application layer.

Choosing Between a Widget Builder or App Builder

Widget builders such as Retool, Appsmith, ToolJet, and Budibase are well suited to quickly building admin panels and internal tools around existing data.

Full-stack platforms such as Modelence go further by combining the frontend, backend, DB, authentication, and deployment, making them a better fit when an internal tool may grow into a more complete application.

Final Thoughts

The best Retool alternative depends on whether you need a faster internal-tool builder or more control over a complete application.

Appsmith, ToolJet, Budibase, and similar platforms are strong fits for teams that mainly need dashboards and admin tools, while code-first and full-stack options give developers more ownership as requirements grow.

Modelence is worth considering if you are starting from scratch or expect an internal tool to grow into a larger application. You can try Modelence for free to see whether its full-stack approach fits your workflow.
