Self-hosted alternatives to Bolt.new
Bolt.new is a hosted AI builder that creates websites, web apps and mobile apps from a chat prompt, with a database and hosting included. 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 Bolt.new describes on its own site.
Bolt.new features, app by app
| Feature | VibeSDK |
|---|---|
| Build websites and apps by chatting with an AI agent | Yes |
| Plan mode before code is written | Partly |
| Live preview of the running app | Yes |
| Visual edits on the preview | No |
| Code view for editing files | Partly |
| Backups, restore and version history | Yes |
| Built-in database and hosting | Partly |

Self-hostable AI app builder from Cloudflare: describe an app and an agent plans, builds, previews and repairs it
- What a Bolt.new 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 websites and apps by chatting with an AI agent. An agent builds full-stack apps from a description and streams its plan, file edits and tool activity.
- Partly Plan mode before code is written. The agent asks structured clarifying questions when a request is underspecified, but there is no separate plan mode.
- Yes Live preview of the running app. Previews load as Dynamic Workers without a long-running development server.
- No Visual edits on the preview. No visual editing on the preview found.
- Partly Code view for editing files. An integrated code editor shows generated files but is read-only in the chat view; projects can be exported.
- Yes Backups, restore and version history. Restore points and rollback through Cloudflare Artifacts, which is off unless ENABLE_ARTIFACTS is set.
- Partly Built-in database and hosting. Isolated SQLite storage per generated app; deploying to the user's own Cloudflare account is behind ENABLE_USER_ACCOUNT_DEPLOY, and no hosted database service for generated apps is described.
- Partly GitHub import and version control. Generated apps can be exported to GitHub repositories through a separate GitHub export flow; importing an existing repository is not described.
