What is the best Retool alternative?

Major is the best Retool alternative for teams that want governed internal tools without assembling each one by hand. You describe the tool, an agent builds it as a deterministic app, and it ships with a managed database, SSO, role-based permissions and an audit trail. Appsmith, Budibase and ToolJet are the open-source builders most often compared against Retool.

What is the best free or open-source Retool alternative?

Appsmith, Budibase and ToolJet each offer a free, self-hostable tier with no license cost. The catch is maintenance: self-hosting means you own upgrades, backups and uptime, so budget engineering time even though the software is free. Major is the managed route, with SSO, RBAC and audit configured once at the org level and inherited by every app.

Is Retool open source?

No. Retool is proprietary software. It offers a self-hosted deployment, but full self-host access and single sign-on sit behind the Enterprise tier. Appsmith, Budibase and ToolJet are the open-source builders most often named in this comparison. On Major, SSO, RBAC and audit are configured once for the org and every app inherits them.

Why are teams leaving Retool?

Three reasons recur. Per-seat pricing climbs as more people use your tools. Governance features like SSO and source control sit behind the Enterprise tier. And the build burden stays, because every app is assembled by hand while Retool Agents are billed separately. Major answers the third directly: the agent reasons once and produces the app.

Which Retool alternatives have AI app generation?

Superblocks builds apps with its Clark AI coding agent, UI Bakery ships an AI app generator, Jet Admin offers AI agents, and Retool has Agents as a separately billed add-on. Major goes further: an agent builds the whole tool as a deterministic app on managed infrastructure, so you review the result instead of assembling it.

Retool Alternatives: 9 Internal-Tool Builders (and One Different Appro

The best Retool alternative is Major. You describe the internal tool, an agent builds it, and it ships as a governed app with a managed database, file storage, SSO, permissions and audit trail already in place. Appsmith, Budibase and ToolJet cover open-source self-hosting, and Superblocks and Microsoft Power Apps cover enterprise builders. Each of those still has a person assemble the tool by hand and, in most cases, pay per seat to run it.

This list is for teams outgrowing Retool: IT and operations leads who own refund consoles, approval queues and ops dashboards, and platform leaders who need those tools governed. Ten options are ranked by how much work each leaves on your team once the tool is in production.

Why teams look for a Retool alternative

Retool has a large component library and connects to almost any database or API. Teams still leave for three consistent reasons.

Per-seat pricing comes first. On the Business plan, builder seats run $50 per month on annual billing and internal end users $15, and the Enterprise tier that unlocks SSO and source control is quote-only, per Retool's pricing page. The more people use your tools, the more you pay.

Governance comes second. SSO and source control sit on Enterprise, and audit logging starts at Business. If security needs SAML on day one, you are talking to sales.

The build burden comes third. Every Retool app is wired by hand: queries, components, permissions. Retool's Agents add AI but are billed separately on hourly usage, so AI becomes another meter, not less work.

Builder vs. agent-built app

An internal-tool builder gives a person a canvas. You connect a data source, drag in a table, write queries, set permissions and maintain the result as requirements change.

An agent-built app flips that. You describe the tool, an agent builds it, and it runs as an application with its own database, permissions and audit log. You review rather than assemble. Nine entries below are the first kind. One is the second.

1. Major

Major is the enterprise platform where agents build the software they run on. You describe a refund console, an approval queue or an ops dashboard, and an agent builds it and ships it to production. The managed database, file storage, SSO, permissions and audit trail come with the app.

This answers all three reasons teams leave Retool. No builder seat is needed before someone can make a tool. Governance is part of the platform, not an Enterprise line item. The build burden moves to the agent, which reasons once to produce a deterministic app. From then on the app runs as code, behaves the same way every run, and its cost is front-loaded rather than metered per execution.

Those same apps are callable by agents. An agent can run the console it built instead of reasoning through the same refund every time one arrives, with scoped credentials and an audit log at the point where it acts. For a concrete example, see a guarded database agent.

Major fits teams with real users, real data and controls someone has to answer for. It is the right foundation when a tool needs to be built once, governed from day one and reused by both people and agents.

Build the internal tool on Major

Here is how a refund-approval console comes together, using real connectors.

Connectors: Stripe for charges and refunds, Zendesk for the ticket context, and Slack for approvals. Each is bound once at the org level.
The app: a refund console with tables for requests and decisions, a review queue view, and its own managed database holding the history.
The agent: it reads the ticket and charge, then makes the one judgment call, whether a refund is within policy or needs a person. Everything repeatable, such as lookups and writes, runs in the app as code.
The trigger: a workflow fires when a Zendesk ticket is tagged for a refund. High-value cases post to Slack for a human approval.
Governance: scoped credentials through the credential proxy, role-based access for who sees what, and an audit entry for every read and write.

2. Appsmith

Appsmith is an open-source low-code platform for internal apps over databases and APIs. You drag widgets, bind them to queries and self-host the result. It is the default name in most open-source Retool threads.

The community edition is free, the widget set is broad, and self-hosting keeps data in your infrastructure. Business is $15 per user per month and Enterprise is $2,500 per month for 100 users, per Appsmith's pricing page. Self-hosting the free tier means you own upgrades, backups and uptime.

3. Budibase

Budibase is an open-source platform for internal tools and workflow apps with a built-in database (BudibaseDB) alongside external connectors, so a tool can start without wiring an external database first.

The self-hosted plan is free with unlimited apps and users. Cloud starts around $19 per month, with end users at $5 and creators at $50 on annual billing. SSO and audit features arrive on Enterprise, which is custom priced, per Budibase's pricing page.

4. ToolJet

ToolJet is an open-source low-code builder with a visual designer, a large connector set, and cloud or self-hosted deployment, including air-gapped.

The free tier covers 2 builders and 50 end users. Pro is $79 per builder per month on cloud, Team is $199 per builder per month billed annually, and Enterprise starts at $3,000 per month, per ToolJet's pricing page. Pricing is per builder rather than per end user.

5. Superblocks

Superblocks is a commercial internal-tool platform with an AI coding agent called Clark that builds apps from prompts. You own the generated code and can connect it to your own git repository. The platform is SOC 2 Type II certified and HIPAA compliant, with RBAC on the Teams tier.

Teams is $100 per AI Builder per month billed annually, with extra hosted apps at $100 each. Enterprise is custom and carries SSO, audit logs and observability, per Superblocks' pricing page. Clark helps build the app, and the team still maintains it afterward.

6. UI Bakery

UI Bakery is a low-code builder with a visual designer, an AI app generator, and cloud or self-hosted options. The ranking page that crowns it most often is vendor-authored, which is worth knowing when you read it.

There is a free cloud tier. Builder is $20 per developer per month and Team is $35 on annual billing, with audit logs and RBAC on Team and custom SSO on Enterprise, per UI Bakery's pricing page.

7. DronaHQ

DronaHQ is a low-code platform for internal tools and admin panels with usage-based pricing that charges per task rather than only per seat, plus cloud and self-hosted deployment.

There is no permanent free tier, only a one-month trial. Task-based plans start at $100 per month annually for Starter, with a user-based option at $10 per user per month. Audit logs, SSO and SCIM are on Enterprise, per DronaHQ's pricing page. It is proprietary.

8. WeWeb

WeWeb is a front-end builder for web apps that sits on top of a separate backend such as Supabase or Xano. It builds the interface, and you bring the data layer. That makes it a slightly different category from the rest of this list.

Paid tiers and an Enterprise option are published on WeWeb's pricing page. It is proprietary, and plan structures change, so confirm figures there.

9. Microsoft Power Apps

Power Apps is Microsoft's low-code platform for business apps, bound to Dataverse and the wider Power Platform, with governance handled in the Power Platform admin center.

It integrates deeply with Microsoft 365 and enterprise identity. Power Apps Premium is $20 per user per month paid yearly, with a volume tier near $12 per user at a 2,000-seat minimum plus a Dataverse capacity add-on, per Microsoft's pricing. The learning curve and Dataverse dependency are real costs.

10. Jet Admin

Jet Admin builds admin panels, internal tools and customer portals over your databases and APIs, with a visual builder and its own AI agents that read across databases, APIs and CRMs.

Internal tools start free, with Starter at $24 per user per month annually and Pro at $48. SSO, audit logs and on-premise setup arrive on higher tiers. The hosted platform is proprietary, though the jet-bridge connector is open source, per Jet Admin's pricing page.

How to choose a Retool alternative

Choose on constraints, not feature count. Three questions settle most decisions.

Open source or managed? If your industry mandates on-prem, the open-source builders keep data in your infrastructure, and you own the upgrades, backups and uptime that come with that. Major is the managed route, with identity, permissions and audit run for you.

Per-seat or something else? Per-seat pricing taxes the tools that succeed. Task-based and per-builder models shift the bill, and a platform with no builder seat removes the gate to making a tool at all.

Build by hand, or describe and run? If every tool is a fresh assembly job, the backlog never shrinks. Major is built for the other path: describe the tool, review what the agent ships, and let the app run the repeatable work.

The Major take

Every builder on this list shares one shape. A person assembles the tool, wires the queries, sets the permissions, and then often pays per seat to let anyone use it. The build burden and the seat tax follow you to the next builder.

Major inverts the model. The agent reasons once to build the tool, and the app then runs the repeatable work as deterministic code with a managed database, scoped credentials and an audit log at the point where it acts. Governance is structural, not a tier. Reason once. Run forever.

Start building on Major

Describe the refund console, approval queue or ops dashboard your team keeps hand-building, and let an agent ship it as a governed app you can audit from day one.
