No-code apps and databases decision
Bubble
A compact, opinionated no-code builder (visual editor + data bindings + deploy) is feasible for a small team to build and run, but reproducing Bubble's full product, integrations, polish, and scale is not practical.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Bubble alternatives, with the arithmetic →
What a replacement has to do
- Provide a minimal web-based no-code app builder that lets a user define data models, drag UI elements onto a canvas, bind UI elements to data endpoints, add simple workflows (button → API/database), and publish the app to a URL.
What it still won’t have
- polish and production UX of Bubble's editor
- broad third-party integrations and plugin marketplace
- scale, uptime guarantees, and multi-tenant operational maturity
- enterprise features (teams, roles, billing, advanced data connectors)
What remains hard
- Product polish and ongoing maintenance

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hostable no-code web app builder using React for the editor, Node.js/Express for the backend, and Postgres for storage. In scope: a drag-and-drop canvas with a component palette and property inspector, a schema editor to create simple data models (strings, numbers, relations), a REST API that exposes CRUD for models, client-side bindings from components to API endpoints, a simple workflow runner (button → API call → state update), user signup/login (email+password), and a one-click deployment script to a single managed server (Docker). Out of scope: plugin marketplace, advanced multi-tenant billing, mobile-native export, and third-party enterprise connectors. Deliver error handling for API/database failures, input validation, and unit tests for backend endpoints plus end-to-end tests for the editor's basic flows.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 3 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score64
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
