Self-hosted alternatives to Base44
Base44 is an AI platform that builds apps, websites and agents from plain-language descriptions, with a built-in backend and hosting. 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 Base44 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 Base44 user would miss
- Managed auth, integrations, custom domains for apps and analytics; 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 account, with model calls routed through AI Gateway and isolated SQLite storage per generated app.
- Yes Build apps, websites and agents from plain-language descriptions. An agent plans, edits files and iterates from a description.
- Partly Built-in backend with database and authentication. Isolated SQLite storage per generated app that you can inspect and reset; no auth service for generated apps found.
- Partly Built-in hosting. Previews run as Dynamic Workers; deploying generated apps to your own Cloudflare account is behind ENABLE_USER_ACCOUNT_DEPLOY.
- No One-click integrations with services such as Gmail, Slack and Notion. No one-click integrations for generated apps described.
- No Custom domain support. The custom domain in the setup guide is for the platform itself, not for generated apps.
- Partly In-app code editing. An integrated code editor shows generated files but is read-only in the chat view; projects can be exported.
- No Analytics dashboard. No app analytics described.
- Yes Conversational refinement with the AI. Follow the agent's plan, edits and tool activity as it works and steer it.
