Self-hosted alternatives to Lovable
Lovable is a hosted AI platform that builds and deploys full-stack web apps from natural-language prompts. One listed app does its main job and runs in your own Cloudflare account.
Each answer comes from the app’s README and source code, compared with the features Lovable describes on its own site.

Self-hostable AI app builder from Cloudflare: describe an app and an agent plans, builds, previews and repairs it
- What a Lovable user would miss
- Visual edits on the preview, a built-in backend with auth and file storage, two-way Git sync and a managed publish flow; setup needs a Workers Paid plan, Workers for Platforms access for production previews and model provider credentials.
- What it adds
- MIT licensed and the code behind Cloudflare's hosted builder at build.cloudflare.dev, run in your own Cloudflare account; model calls route through AI Gateway to the providers the reader configures, each generated app gets isolated SQLite storage, and the agent reads browser console output and repairs runtime errors.
- Yes Build apps by chatting in natural language. An agent plans, edits files and iterates from a description, and asks structured questions when a request is vague.
- Yes Live preview of the running app. Each commit is bundled and loaded as a Dynamic Worker preview with signed, branch-scoped URLs.
- Partly Code editor and code download. An integrated code editor shows generated files but is read-only in the chat view; projects can be exported.
- Yes Version history with revert. Restore points and rollback through Cloudflare Artifacts, which is off unless ENABLE_ARTIFACTS is set.
- Partly Built-in backend with database, auth, storage and functions. Each generated app gets isolated SQLite storage through a Durable Object Facet that can be inspected and reset; no auth or file storage service for generated apps found.
- Partly Publish with hosting and custom domains. Previews run as Dynamic Workers, and deploying generated apps to the user's own Cloudflare account is behind ENABLE_USER_ACCOUNT_DEPLOY; the custom domain in the setup guide is for the platform itself.
- Partly Git sync to GitHub. A separate GitHub export flow exports generated apps to repositories; no two-way sync found.
- No Visual edits on the preview. No visual editing on the preview found.
