The 11 best Appsmith alternatives in 2026, compared

The short answer. ToolJet is the closest swap: open source, self-hostable, and with SSO on a published plan below Enterprise. Retool is the closest commercial swap, with the deepest internal-tools feature set and a self-hosted option, though its SSO is Enterprise only too. If your people now build with Claude Code, Codex or Cursor and want to ship that code as it is, Tray Helix deploys and governs those apps with SSO, managed credentials and an audit trail. Microsoft Power Apps fits a company already standardized on Microsoft, Superblocks fits a team that wants a governed builder priced per team, and Lovable, v0 by Vercel, Replit, Bolt and Base44 suit one builder who wants a hosted app from a prompt.

Two groups search for Appsmith alternatives, and they want opposite things. The first is a developer team that picked Appsmith on purpose and still likes it. What changed is the bill or the checklist. Appsmith’s Business plan charges $15 a month for every member, builders and app users alike, so a tool that started with five engineers grows with every colleague who opens it. And when security asks for SAML or OIDC single sign-on, the answer is Enterprise, which starts at $2,500 a month for 100 users. That group wants the same kind of platform with a different meter or a lower SSO threshold, and it stays among the internal tool platforms on this list.

The second group has stopped assembling widgets. Its engineers and analysts build in Claude Code and Cursor now, and what comes out is ordinary TypeScript and React. Appsmith’s copilots generate widgets and logic inside the Appsmith editor; this group wants to keep the code where the assistant wrote it and give it somewhere governed to run. It ends up at the runtime end of the list.

Appsmith alternatives at a glance

Pricing last checked against each vendor’s published pricing page on 6 October 2026. Lovable, v0, Replit, Bolt, Superblocks and Appsmith show monthly prices; Retool, ToolJet, Base44 and Power Apps Premium are billed yearly. Enterprise tiers are custom-priced everywhere on this list except Appsmith’s, which starts at $2,500 a month for 100 users.

The Appsmith row is worth a worked example, because the jump between tiers is where most searches start. Free covers up to five users on the cloud. Business is $15 per user a month for up to 99 users, with audit logs and granular roles, and Enterprise, which carries SAML and OIDC SSO and SCIM, is $2,500 a month for 100 users.¹

A 40-person team on Business pays $600 a month. The day it needs company SSO, the same 40 people cost $2,500 a month. The Community Edition is free to self-host, though it doesn’t include those enterprise identity features either.

A governed runtime for apps built in your own assistant

Tray Helix

Best for: teams whose builders already work in Claude Code, Codex or Cursor, where IT wants every resulting app deployed, identified and owned through one path.

A Helix app is plain TypeScript and React with whatever component library the team prefers, which is the code AI assistants write best. The builder runs it locally with helix dev, where the assistant can make real authenticated calls and read logs without deploying, then ships it with helix deploy to Tray’s managed runtime and a URL. Each app deployed that way goes live behind your company SSO, with credentials held in Tray auth aliases and kept out of the code, an audit trail, a named owner and a registry entry. Activity, logs and health are visible from the first request.

For an Appsmith team, the backend matters. Appsmith apps read and write the databases and APIs you connect. A Helix app gets a database, a key-value store, persistent file storage with audit logs, scheduled functions and triggers from the runtime, plus native OAuth into more than 800 services, so the app can reach Salesforce or Slack without anyone pasting an API key.

Helix publishes its pricing: it starts at $50 per workspace a month plus $1.00 per HCU of usage, cheaper on a commitment. With no per-user line, the colleagues who only open an app aren’t on the bill, and AI and compute spend is visible per app.

Helix runs on the Tray platform, which runs workloads for Airbnb, DoorDash, DocuSign and Cisco, with SOC 1 Type II, SOC 2 Type II and GDPR, and data residency in US, EU and APAC regions.

Trade-offs: Helix doesn’t write the app, and there’s no drag-and-drop fallback. If the developers who maintain your Appsmith tools won’t open an AI assistant, stay on a builder. Helix is managed cloud only today, so a team that chose Appsmith to run everything on its own servers, or air-gapped, has no equivalent here, and that is a real reason to look at ToolJet or Retool instead. There’s no import path for Appsmith apps. An app moves by being rebuilt in the assistant, which is ordinary code work, and it’s still work. Apps that stay on Appsmith stay outside what Helix governs.

AI app builders

Lovable

Best for: one person who needs a working, hosted app quickly and doesn’t need it on an internal tool platform.

Lovable is the fastest route from a description to a shareable URL, with a frontend, database, auth, storage and hosting in one flow. It is one of the few products here with SAML and OIDC SSO on a self-serve plan: Business, from $50 a month, with no per-viewer charge.² It carries SOC 2 Type II and ISO 27001 and syncs code two ways with GitHub or GitLab.

Trade-offs: Lovable is built for point solutions. Admin panels over your own production databases are Appsmith’s home ground, there’s no self-hosted option, and AI work is metered in credits.

v0 by Vercel

Best for: engineering teams who want generated React and Next.js interfaces on Vercel’s platform.

v0 generates the stack your engineers may already run, on a platform with SOC 2 Type 2, ISO 27001 and a 99.99% SLA on Enterprise. There is a free tier, and Business is $100 per user a month.³

Trade-offs: pricing is per user, so a team leaving Appsmith over its per-user bill trades one seat meter for a steeper one.

Replit

Best for: a small team that wants an IDE, a building agent and hosting together in a browser tab.

Replit bundles an agent that tests its own work, a managed Postgres database, storage and hosting. Core is $20 a month and Pro is $100 a month for up to 15 collaborators.⁴

Trade-offs: SSO is on Enterprise only, and the build environment is Replit’s own, which is no help to a team that has moved to local assistants.

Bolt

Best for: a person or small team that wants a hosted full-stack app from a prompt with nothing to install.

Bolt, from StackBlitz, runs its agent in a full Node.js environment inside the browser, and Bolt Cloud, launched in August 2025, supplies hosting, databases, auth, storage and edge functions.⁵ Every publish has run a security audit since July 2026, and projects sync two ways with GitHub. Pro starts at $25 a month and Teams is $30 per member a month.

Trade-offs: SSO and audit logs are Enterprise only, and token use grows with project size, so a long-lived internal tool gets more expensive to change over time.

Base44

Best for: a business user who wants a hosted app with a database from a description, without running Appsmith or writing queries.

Base44, owned by Wix since June 2025, builds the screens, data model, sign-in and logic from a description, then hosts the result with a MongoDB-compatible database, serverless functions, and email and file integrations included. Engineers can take over the code through two-way GitHub sync on paid plans. There’s a free tier, then Starter at $16 a month and Pro at $80, billed yearly.⁶

Trade-offs: Base44 is the build surface and the runtime together, so the app lives on Base44’s platform and its governance covers apps built there. Workspace SSO sits on its Business and Enterprise plans, a threshold much like Appsmith’s, its governance covers only apps built on Base44, and AI work is metered in monthly credits.

AI and internal app platforms

Retool

Best for: teams that want the most mature commercial internal tool platform, including a self-hosted option, and can live with Enterprise-only SSO.

Retool is what Appsmith is most often measured against, and for a team moving off Appsmith because it wants more depth, it is the natural swap. It has built internal tools since 2017 and claims more than 10,000 teams.

Credentials are applied server-side and Retool proxies data requests, so builders never hold database passwords, and the connector library and permission model have been refined across thousands of deployments. Self-hosted and air-gapped deployment are available, and Retool is SOC 2 Type 2 and ISO 27001 certified.⁷

Its AI work is the most developed in this group. In June 2026 Retool launched a React and TypeScript AI app builder, MCP support so Claude Code and other coding agents can build and edit Retool apps, and governance for AI-coded apps imported from Claude Code, Cursor, Lovable or Replit.⁸

On price, Retool solves neither Appsmith complaint on its own. Team is $10 per builder and $5 per internal user a month billed yearly, which is cheaper than Appsmith Business for a team with few builders and many users: three builders and 37 users come to $215 a month against Appsmith’s $600. But SAML and OIDC SSO and SCIM are Enterprise only on Retool as well, and Business, at $50 per builder and $15 per user, costs more than Appsmith’s.⁹

Trade-offs: every internal user is still a line on the bill, SSO is custom-priced, and AI is metered separately in credits and hourly agent billing. Retool’s core is closed source, so a team that picked Appsmith for Apache 2.0 gives that up.

Superblocks

Best for: teams that want a governed internal app platform with AI at the centre and a flat price per team.

Superblocks prices per team: Teams is $125 a month, or $100 billed yearly, for up to 15 builders, unlimited end users and one hosted app, with $10 a month for each additional app.¹⁰ Its agent, Clark, applies design systems, permissions and tests while it generates, and Enterprise customers can run the data plane in their own VPC.

Trade-offs: SSO, audit logs and VPC deployment are on Enterprise, which is custom-priced, so the SSO problem that sends some teams away from Appsmith is still there. There’s a 14-day trial, with no free tier and no open-source edition.

Appsmith

Best for: developer teams building admin panels, dashboards and CRUD tools over databases they already run, especially where open source or self-hosting is the requirement.

Appsmith is one of the few internal tool builders that is genuinely open source, and staying on it is a sound choice for many teams. The Community Edition is Apache 2.0 licensed, maintained in public with more than 41,000 GitHub stars, and free to run on Docker, Kubernetes or an AWS AMI; Enterprise adds an air-gapped edition.¹¹ You can read the code you depend on and change it if you have to. Few platforms on this list can say that.

The builder is quick at its core job. Widgets make a responsive interface, queries reach Postgres, MySQL, MongoDB, Snowflake, REST and GraphQL APIs and tools such as Salesforce and Slack, and JavaScript is available everywhere for logic. Apps sync to any Git provider with branch protection and separate environments.

Appsmith is SOC 2 Type II, audit logs and granular roles arrive on Business, and SAML and OIDC SSO, SCIM and 24x7 support arrive on Enterprise.¹² On AI, copilots generate custom widgets and logic from natural language, and the Appsmith AI datasource adds text and image operations without an API key.

Trade-offs: every member on Business counts toward the bill, and company SSO starts at $2,500 a month. The Appsmith editor is the build surface, so code written by an assistant outside it doesn’t become an Appsmith app. Its newer launches, Appsmith Agents in 2025 and the Kite website builder in April 2026, sit beside the internal tool product and leave it as it was.¹³

ToolJet

Best for: teams leaving Appsmith that want to stay open source and self-hosted, and need SSO below an Enterprise contract.

ToolJet is the most direct swap on this list. The core is on GitHub under AGPL-3.0, with more than 40,000 stars and a free Community Edition that runs on Docker, Kubernetes, a VPC or on-premise; Self-hosted Enterprise adds air-gapped operation.¹⁴ Note the licence difference: AGPL-3.0 places obligations on modified versions that Apache 2.0 doesn’t, so check it with whoever owns open-source policy before you move.

The product covers the same ground as Appsmith and adds to it: a visual builder with more than 80 components, a built-in PostgreSQL database in every workspace, and workflows. ToolJet AI generates screens, queries and data bindings from a description. Since 2 September 2026, ToolJet MCP has let Claude Code, Codex and Cursor build ToolJet apps on the builder’s own agent subscription, and those apps stay editable in the visual builder, so a developer and an operations lead can work on the same tool.¹⁵

The pricing answers the SSO complaint directly. ToolJet charges per builder: Basic $23, Pro $79 and Team $199 a month, billed yearly ($29, $99 and $249 monthly). SAML, OIDC and LDAP SSO and audit logs with 14 days of retention arrive on Team, which allows up to 100 end users; SCIM and unlimited end users are Enterprise.¹⁶ Three builders on Team come to $597 a month billed yearly with SSO, against $2,500 for Appsmith Enterprise.

Trade-offs: end users are limited below Enterprise, so a tool that spreads past 100 people forces the upgrade anyway. Apps built through ToolJet MCP are ToolJet apps, so you won’t find them as plain code in your repository. Audit retention on Team is 14 days.

A platform IT may already run

Microsoft Power Apps

Best for: Microsoft-standardized companies whose internal apps live on Microsoft data.

Power Apps puts Entra ID sign-in on every app, which matters to an Appsmith team stuck on SSO: identity comes from the tenant, whatever the pricing tier. Managed Environments, data policies, Purview audit logs and the Power Platform inventory give IT governance in tools it already runs. Code apps, generally available since 5 February 2026, let developers build React or Vue in their own IDE and publish with pa app push.¹⁷ Premium is $20 per user a month billed yearly ($12 at 2,000 seats and up), and Microsoft 365 licences carry limited rights, so it is often already paid for.

Trade-offs: every end user needs a licence, and premium connectors need Premium. Outside Microsoft data, the fit weakens, and there is no self-hosted or open-source option.

Your own platform

Building it yourself

Best for: teams already self-hosting Appsmith, with platform engineers who maintain an internal developer platform.

If you self-host Appsmith, you already run a cluster, an identity provider integration and a backup routine. Building your own runtime for code-first internal apps extends that, with no licence and full control over where everything runs.

Trade-offs: every app still needs hosting, SSO wiring, secrets, logging and a tested way back to a previous version, and the work repeats with each new app.

How to choose

• Stay open source and self-hosted, with SSO on a published plan: ToolJet
• More depth, a mature commercial platform, self-hosting still available: Retool
• Builders in Claude Code, Codex or Cursor who want to ship plain code under SSO and an audit trail: Tray Helix
• A Microsoft-standardized company building on Microsoft data: Microsoft Power Apps
• A governed builder priced per team with unlimited end users: Superblocks
• Admin panels over your own databases, Apache 2.0, or air-gapped hosting: stay on Appsmith
• One person, one hosted app, fast: Lovable or Bolt
• A business user who wants a hosted app with a database from a description: Base44
• Engineering-owned React and Next.js interfaces on Vercel: v0 by Vercel
• A small team that wants the IDE, agent and hosting together: Replit
• Platform engineers and a reason to own the runtime: build it yourself

What actually moves teams off Appsmith

SSO arrived on the checklist. Free and Business support Google and GitHub sign-in, which is fine until security asks for the company identity provider. At that point the price moves from per user to $2,500 a month, and a small team feels that jump more than a large one.

The user count grew. Every member on Business is $15 a month. A tool that spreads across a department grows the bill with headcount, while the work of maintaining it stays the same.

The builders changed tools. The developer who wired widgets to queries last year asks Claude Code for a React app today. Appsmith’s copilots work inside its editor. Teams that want the code to stay ordinary code, in their own repository, go looking for a runtime.

Appsmith is still a strong product. For open-source internal tools on your own infrastructure it’s one of the best options. A team with dozens of working Appsmith apps should count the rebuild cost before moving anything. Teams that move are usually reacting to a change in who uses the tools, who has to sign in, or how the tools get built.

Frequently asked questions

What is the best Appsmith alternative?

ToolJet if you want to stay open source and self-hosted with SSO on a published plan, and Retool for a more mature commercial platform. If your builders work in Claude Code, Codex or Cursor, Tray Helix deploys those apps with SSO, managed credentials and an audit trail.

Why do teams leave Appsmith?

Mostly because SAML and OIDC SSO are on Enterprise only, because the Business bill grows with every user, or because builders have moved to AI assistants and want to ship the code those assistants write.

Is Appsmith cheaper than Retool?

It depends on who uses the tools. Appsmith Business charges $15 for every user. Retool Team charges $10 per builder and $5 per internal user billed yearly, so for a few builders and many users Retool Team costs less. Both put SSO on Enterprise, and at Business level Retool costs more.

Is there an open-source, self-hosted alternative to Appsmith?

Yes. ToolJet is open source under AGPL-3.0 with a free self-hosted Community Edition, and Retool offers self-hosting without being open source. Superblocks Enterprise can run its data plane in your VPC. Tray Helix is managed cloud only today, with data residency in US, EU and APAC regions.
