You've chosen Supabase as your backend. Now you need a frontend.
Can you use Bubble? A short answer: no.
Bubble uses a proprietary database and can’t connect to Supabase.
So which Bubble alternatives actually work with Supabase?
This guide evaluates five platforms on five Supabase-specific criteria: integration method, real-time subscription support, Supabase Auth, row-level security compatibility, query flexibility, and handoff.
Let’s dive in.
Why Bubble Can't Connect to Supabase
Bubble is built around a proprietary database, and it stores your data in its own closed system. You can't point it at an external PostgreSQL database or use Supabase as a data source.
If you've chosen Supabase for its PostgreSQL foundation, row-level security, real-time capabilities, or Auth system, keep in mind that these don’t carry over to Bubble.
In this article, we’ll explore Bubble alternatives for Supabase.
What "Good Supabase Integration" Means
Here's what a “good Supabase integration” should have.
Integration method: is Supabase a first-class plugin with visual setup, or are you manually configuring REST endpoints? Native plugins give you faster setup, built-in error handling, and automatic access to Supabase-specific features. REST-only connections treat Supabase like any generic API, and you miss real-time, Auth, and RLS support out of the box.
Real-time subscriptions: Supabase Realtime lets your app subscribe to database changes and update instantly without polling. If real-time data matters to your use case (dashboards, collaboration features, notifications) check this before committing.
Supabase Auth integration: when a frontend uses Supabase Auth natively, your user's JWT token flows through database queries. That enables row-level security at the database layer. When auth is managed separately, you get two identity systems and a manual wiring job. Aim for the first architecture model.
Row-level security compatibility (RLS): RLS enforces per-user data isolation in Supabase. Frontends that send user-scoped JWTs let RLS do its job at the database level. Frontends that connect with a service role key bypass RLS entirely, shifting security responsibility to the application layer. For multi-tenant apps, this is a serious concern.
Query flexibility: most apps have relational data. You need filters, joins, foreign key traversal, and complex conditions. A tool that only fetches all rows from a single table will force you to flatten your database to work around its limitations.
WeWeb: Best Overall Supabase Integration
WeWeb is a visual no-code app builder with two native Supabase plugins: one for data, one for auth.
How the integration works: You can connect your Supabase project with your project URL and API key. WeWeb's data plugin gives you a visual query builder for fetching, filtering, sorting, inserting, updating, and deleting records.
Complex queries such as relationships, foreign key traversal and PostgREST filter conditions, are all configured without SQL.
The auth plugin handles Supabase Auth natively. Login, signup, and session management all flow through Supabase's auth system. Your authenticated user's JWT passes through queries automatically, which means Supabase's RLS policies apply at the database level without additional frontend logic.
Real-time: WeWeb supports Supabase Realtime subscriptions natively, including database change events, broadcast, and presence. Components update live when Supabase data changes without polling or manual refresh.
Edge Functions: you can trigger Supabase Edge Functions from WeWeb's visual workflows without leaving the builder.
Pricing: From $16/month. Unlimited app users on all paid plans, no per-user fees.
Lovable: Supabase As Default Backend, But With Caveats
Lovable is an AI-first builder where Supabase is the default backend. Every Lovable project automatically provides a Supabase project. You describe what you want in chat and Lovable generates the UI, database schema, RLS policies, and Edge Functions.
How the integration works: Supabase Integration 2.0 improved error handling, role management, and schema editing. Supabase Auth is supported natively: email/password and OAuth providers configured via the AI chat interface.
Real-time is available. RLS policies are set up as part of the generation flow.
The trade-off: Lovable is chat-first. After AI generation, making precise changes means re-prompting and hoping the AI interprets your intent correctly. This is what builders call "prompt purgatory." In addition, to understand what was generated, you need to be able to read and fix AI-generated code.
Pricing: the pricing model is credit-based and it can become unpredictable depending on the complexity of your app.
FlutterFlow: Mobile-First Supabase Apps
FlutterFlow generates Flutter/Dart code primarily for iOS and Android from a single visual builder.
How the integration works: you can connect via your Supabase project URL and anon key in FlutterFlow's settings panel. Full CRUD operations are configured as backend actions in the visual editor.
Supabase Auth is supported for email/password, Google, and Apple sign-in.
The trade-off: the JWT token generated for authenticated users is not included in requests made using FlutterFlow's native triggers, which prevents RLS policies from working effectively.
This forces builders to work only with public tables or use workarounds like custom curl-based API calls to pass the user's JWT.
In addition, Supabase Realtime backend queries exist, but reliable real-time behavior in production often requires workarounds.
Pricing: seat-based, no per-user fees.
Retool: Supabase as a Database
Retool is a popular internal tools builder with strong SQL capabilities. It connects to Supabase but as a generic PostgreSQL database, not as a native integration. There is no dedicated Supabase plugin.
This means that Retool can query your Supabase tables with SQL but it can’t use Supabase Realtime, integrate with Supabase Auth, or access any of Supabase's platform-specific features without significant manual engineering.
Real-time: not built in. Adding Supabase Realtime to Retool requires manually importing the Supabase JS library via Retool's Libraries menu and writing custom JavaScript. This is a community workaround, not a supported feature.
Auth and RLS: Retool manages its own authentication separately. Queries run with a service role connection by default, which bypasses row-level security entirely. Access control must be enforced manually at the application layer. For trusted-admin internal dashboards, this is often acceptable. For any multi-tenant or user-facing application, it is a security gap.
Query flexibility: strong. Retool gives you full SQL access to your Supabase Postgres tables. If your team knows SQL and needs a fast internal dashboard, Retool might be a good choice.
Pricing: per-user fees for app users, costs compound with headcount.
Appsmith: Open-Source, With Certain Supabase Limitations
Appsmith is an open-source internal tools builder. It connects to Supabase via PostgreSQL through Supabase's Supavisor connection pooler or REST API. Appsmith is listed as an official Supabase partner but there is no dedicated Supabase plugin.
Real-time: not supported natively. You can import supabase-js into Appsmith's custom JavaScript blocks to get real-time behavior, but this is a manual workaround, not a platform feature.
Auth: requires a workaround. OAuth2 flows and supabase-js enable auth. But there is no native "connect Supabase Auth" option. It requires developer configuration.
RLS: same service key concern as Retool. PostgreSQL driver connections typically use a service role, bypassing RLS.
However, compared to Retool, Appsmith is open-source and self-hostable at no cost. For teams with on-premise requirements and the engineering bandwidth to operate it, this is a meaningful advantage.
Pricing: free (open-source, self-hosted); cloud tier available.
