Best Retool Alternatives in 2026: 10 Internal Tool Builders

Best Retool Alternatives: The Short Answer

Appsmith is the best overall Retool alternative, because it covers the same SQL-and-API internal tool use case with a free self-hosted edition and simpler per-user pricing. Budibase is best for unlimited self-hosted users, ToolJet is the closest feature-for-feature cloud rival, Softr and Noloco suit non-technical teams on Airtable, Glide suits spreadsheet apps, and Bubble suits tools that grow into products. For a native mobile app for staff or customers, Superapp builds and publishes one from a description.

Quick answer: Appsmith is the closest open-source swap. If the tool needs to become a native iPhone app, Superapp writes native Swift apps for iPhone, iPad, Apple Watch and Mac and handles App Store submission on a paid plan. As a disclosure, Superapp is our product, so weigh this accordingly. Its limits: it is not an internal-tool builder with SQL query panels, it has no Android yet, and credits run out.

Prices were checked on the vendors' own pages in November 2026 unless a row says otherwise.

What Does Retool Cost?

Retool's plans, per Retool pricing on November 10, 2026, billed annually:

External users are metered separately, and Retool says annual billing saves 20%.

Why Do People Look for a Retool Alternative?

• Per-user cost. Every internal user is a seat, so a tool used by a whole company gets expensive.
• Self-hosting. Some teams need to run the tool on their own infrastructure without an Enterprise contract.
• Skills. Retool rewards JavaScript and SQL. Non-technical teams want something simpler.
• Customer-facing apps. Retool is built for internal tools, not polished apps for customers.

The 10 Best Retool Alternatives, Reviewed

In its own words: "ToolJet is the open-source, AI-native low-code platform for internal tools." (source)

Compared with Retool: a Retool-style cloud builder priced per builder.

• Price: Free; Basic $23 per builder a month
• Best for: Teams that want cloud or self-hosted options
• Pitfall: End-user caps per plan
• Not for: Very large internal audiences on low tiers

4. Softr: Best for Non Technical Teams on Airtable

Softr builds portals and internal tools on Airtable, Google Sheets or its own database without code. Basic was $19 a month billed yearly when we checked in October 2026, after an August repricing; see our Softr alternatives page for its limits. It is far easier than Retool and far less flexible.

In its own words: "Softr is an AI app builder for creating portals and internal tools for your business operations, without code." (source)

Compared with Retool: no code at all, for portals on Airtable.

• Price: Basic $19 a month billed yearly (October 2026)
• Best for: Ops teams without developers
• Pitfall: User allowances per plan
• Not for: Complex SQL tools

5. Noloco: Best for Client Portals

Noloco builds portals and internal tools with permissions and workflows on Airtable, Sheets, SQL or its own tables. Build was $65 a month billed annually with 1,000 active clients when we checked Noloco pricing in October 2026.

In its own words: "Noloco brings your team, clients, and data into one system for complex operations." (source)

Compared with Retool: portals for many external users.

• Price: Build $65 a month billed annually (October 2026)
• Best for: Portals for many external users
• Pitfall: PWA only
• Not for: Developer-heavy tools

6. Glide: Best for Spreadsheet Apps

Glide turns spreadsheets and its own tables into mobile-friendly apps for field teams, and GlideOS builds from a prompt. GlideOS Basic was $25 a month when we checked Glide pricing in October 2026.

In its own words: "Glide turns spreadsheets into beautiful, intelligent apps." (source) "Apps stay private to your company by default." (source)

Compared with Retool: mobile-friendly apps from spreadsheets.

• Price: GlideOS Basic $25 a month (October 2026)
• Best for: Field and operations teams
• Pitfall: PWA only
• Not for: SQL-heavy tools

7. Bubble: Best When the Tool Becomes a Product

Bubble suits internal tools that may become customer products, with its own database, workflows and plugins, and native iOS and Android publishing on mobile plans. Starter was $29 a month billed annually when we checked Bubble pricing in October 2026.

In its own words: "Hosting, a built-in database, security, and auto-scaling infrastructure are included, for web and native mobile." (source)

Compared with Retool: tools that grow into products.

• Price: Starter $29 a month billed annually (October 2026)
• Best for: Tools that will grow into SaaS
• Pitfall: Steep learning curve
• Not for: Quick admin panels

8. Airtable Interfaces: Best if Your Data Is in Airtable

Airtable's Interfaces let teams build dashboards and forms on their bases with no extra tool. Team was $20 per editor a month billed annually when we checked Airtable pricing in October 2026.

In its own words: "Teams at over 500,000 forward-thinking organizations use Airtable every day." (source)

Compared with Retool: dashboards with no extra tool.

• Price: Team $20 per editor a month billed annually (October 2026)
• Best for: Teams already on Airtable
• Pitfall: Limited logic and branding
• Not for: SQL databases

9. Superapp: Best for a Native Mobile App

Superapp is not an internal-tool builder with query panels. It is an AI app builder for people who want the finished product without the setup: you describe the app, and it writes native Swift and SwiftUI for iPhone, iPad, Apple Watch and Mac, or a React web app with a managed cloud backend, then publishes the Apple app to the App Store on a paid plan. There is no IDE, terminal, Xcode project setup or API key to manage, and the generated Xcode project can be exported.

It also covers what comes after the build. The Max plan adds Selfdrive, a marketing agent that the pricing page lists as covering "Apple Ads", "App Store optimization", "SEO" and "UGC creators". Selfdrive now markets web apps as well as iOS apps, and its own page says it "Works with apps made in Superapp and outside of it."

The trade-off is control. Developers who want to edit code line by line, work in their own repository or use any language will be better served by the coding tools below. Superapp has no Android output yet, and building and revising spend credits.

In its own words: "AI that builds your iOS or web app and runs your marketing while you sleep." (source) "Superapp generates real, production-ready Swift as a standard Xcode project you own and can export anytime, with no lock-in." (source)

Compared with Retool: a native App Store app or web app instead of an internal panel, marketed with Selfdrive.

• Price: Free credits to start in most countries; Pro $25 a month (50 credits, App Store publishing); Max $100 a month adds the marketing agent
• Best for: Non-technical founders who want a shipped app, not a coding tool
• Pitfall: Less hands-on code control than an editor; credits run out
• Not for: Developers who want to work in their own repo or language

10. Lovable: Best AI Builder for Web Tools

Lovable builds full-stack web apps from a chat, with a database, sign-in and hosting, and it publishes marketing sites too. It is a better fit than a template builder when your "website" is really a product with logged-in users. The free plan gives 5 daily credits up to 30 a month, and Pro is $25 a month, per its plans documentation. Its docs say it does not build native mobile apps.

In its own words: "If you can describe it, you can build it." (source) "Lovable handles hosting, SSL, and backend infrastructure." (source)

Compared with Retool: AI-built web tools.

• Price: Free; Pro $25 a month
• Best for: Web apps and startup sites built by chat
• Pitfall: Credits go fast on complex changes
• Not for: Native iPhone apps or simple brochure sites

What Does Each Retool Alternative Say About Itself?

Marketing copy is not proof, but a vendor's own one-line pitch shows what it is built to do. Each line below is copied verbatim from the vendor's site on November 10, 2026.

Scorecard: How the Retool Alternatives Compare

Our editorial ratings (High, Medium or Low) for the reader each tool suits, based on the facts in this article. They are judgments, not measured scores.

Which Retool Alternative Fits You?

What Does a 20 Person Team Pay per Month?

Our own arithmetic for 2 builders and 18 other users, from published list prices, not vendor quotes.

Retool's entry tier is cheap for small teams; the gap widens on Business at $50 a builder and $15 a user.

What Does Retool Still Do Best?

Retool's component library, database connectors and developer features are among the deepest available, and Retool Mobile gives organizations native apps for staff. For engineering teams that live in SQL and JavaScript, it is still a benchmark.

What Does a 100 Person Team Pay per Month?

Our own arithmetic for 5 builders and 95 other users, from list prices on November 10, 2026.

At this size the open-source self-hosted route is cheapest by far, if you can run it.

Which Retool Alternative Fits Each Kind of User?

Where Does Superapp Fit?

Superapp does two jobs most tools on this list split across separate products. First it builds: a website, a React web app with sign-in and a managed cloud backend, or a native Swift app for iPhone, iPad, Apple Watch and Mac, from a plain-English description. Its features page says "Superapp builds native apps for iPhone, iPad, Apple Watch, Mac, and Vision Pro from one project," and that the output is "a standard Xcode project you own and can export anytime, with no lock-in."

Then it markets. On the $100 Max plan, Selfdrive runs growth after launch, and it now markets web apps as well as iOS apps. The Selfdrive page says "It coordinates Apple Search Ads, App Store optimization, a website and SEO, and UGC creator campaigns," and that it "Works with apps made in Superapp and outside of it." For a web app, the relevant channels are the website, SEO, content and creator campaigns; Apple Ads and App Store optimization apply to App Store apps.

The honest limits: Superapp has no Android output yet, it does not build online stores, credits run out on heavy builds, ad spend and creator fees are paid separately, and Selfdrive is new, so judge it on your own numbers.

What Mistakes Should You Avoid When Leaving Retool?

1. Comparing Retool Team's small-team price with alternatives at company scale.
2. Self-hosting without someone to patch and back up the server.
3. Pricing a builder for today's user count. Model the cost at three times your users.
4. Assuming a PWA is the same as an App Store app. It is not found in App Store search and works differently offline.
5. Locking business logic into a tool with no export.
6. Ignoring permissions. Test what each role can see with a separate account.
7. Rebuilding everything at once. Move one app or portal first.
8. Choosing a developer tool for a team with no developers, or the reverse.

Checklist Before You Switch From Retool

• List every app, page and user role you have.
• Export data and note each data source.
• Count internal and external users today and in a year.
• Rebuild one workflow on the new tool and test permissions.
• Check mobile needs: web, PWA or App Store.
• Plan a cutover date and tell users.
