If you already have a backend, whether Postgres, Supabase, Xano, Firebase or a REST API, you do not need an all-in-one platform that wants to own your data too. You need a front end that connects to what exists. The main split is who the front end is for: your own team, or your customers.
Below are eight no-code front-end builders, with the point where each one stops. For database-specific options, see the best PostgreSQL frontend builders.
What a no-code front end for your backend needs
- Native connectors to your database or API, not just a built-in database.
- Reading and writing data, with validation.
- Authentication and per-user access to data.
- Room for custom code when the visual editor runs out.
- Hosting on your domain.
The eight builders at a glance
| Builder | Best for | Connects to your backend |
|---|---|---|
| Jet Admin | Internal tools and portals | 200+ databases and APIs |
| WeWeb | Customer-facing web apps | Supabase, Xano, REST, others |
| Softr | Simple portals | Airtable, databases and others |
| Bubble | Full web apps | API connector; built-in database |
| Glide | Mobile-first apps | Sheets, SQL and others |
| FlutterFlow | Native mobile apps | Firebase, Supabase, APIs |
| Webflow | Marketing sites | CMS; limited app data |
| Retool | Developer-built internal tools | Databases and APIs |
Front ends for your team and partners
1. Jet Admin
Jet Admin builds the front ends that run a business on top of an existing backend: admin panels, internal tools, dashboards and customer or partner portals. It connects to Postgres, MySQL, Supabase, Xano, Firebase, REST and GraphQL APIs and 200+ other sources, queries data in place and adds its own sign-in and roles, so each user sees only their rows. You describe the app and Jet generates it; custom React, Vue or Angular components and 2-way GitHub sync cover what the visual editor does not.
Users are unlimited on every plan. Granular permissions, SSO and audit logs are on the Business plan and above.
Where it stops: it is not for pixel-perfect consumer apps or marketing sites.
2. Softr
Softr builds portals and internal apps from blocks, fast, on Airtable and other sources.
Where it stops: when you need a component or logic its block library does not have.
3. Retool
Retool gives developers components and JavaScript to build internal tools on databases and APIs.
Where it stops: developer-first, with per-user pricing.
Front ends for your customers
4. WeWeb
WeWeb is a visual front-end builder designed for external backends like Supabase and Xano, with full control over design.
Where it stops: internal admin screens take more work than in internal-tool builders.
5. Bubble
Bubble builds full web applications with workflows and a built-in database, and connects to APIs.
Where it stops: it works best when Bubble owns the data; external databases go through the API connector.
6. Glide
Glide builds mobile-first apps quickly on spreadsheets and SQL databases.
Where it stops: design flexibility and row limits by plan.
7. FlutterFlow
FlutterFlow builds native mobile and web apps in Flutter with Firebase, Supabase and API support.
Where it stops: mobile-first; back-office tools are not its focus.
8. Webflow
Webflow builds marketing sites with a visual editor and CMS.
Where it stops: it is a website builder, not an application front end.

Frequently asked questions
What is a no-code front-end builder?
A visual tool for building the interface of an app, screens, forms and navigation, on top of a backend you connect to.
Can I use a no-code front end with my existing database?
Yes, if it has a native connector or can reach your API. Check whether it queries your data in place or copies it.
Will I be locked in?
Your data stays in your backend. Lock-in is mainly in the front-end logic, which is why code export or GitHub sync matters.
