What is Doable?

Doable is an open-source AI app builder. You describe what you want — “Build me a landing page for a coffee shop with a contact form” — and Doable's AI agent generates a working web app, runs it in a live preview, and lets you keep iterating with chat, visual edits, or code.

Doable in action — chat with AI on the left, live preview building on the right

Think of it as a self-hostable alternative to commercial AI builders like v0, Bolt, Lovable, or Replit Agent — except you own the data, the code, the infrastructure, and the AI keys.

Who is it for?

  • Creators, designers, producers, founders, and CEOs who want to ship without writing code.
  • Developers who want to bootstrap projects 10× faster and still drop into the code when needed.
  • Agencies and SaaS teams that want to host a branded AI builder for their clients.
  • Self-hosters who refuse to send their ideas, code, and business data to closed SaaS.

What makes Doable different?

The 60-second tour

  1. Sign up locally and open the dashboard.
  2. Describe a project in natural language. Doable scaffolds a Vite/React app behind the scenes.
  3. Live preview updates as the agent edits files.
  4. Chat to iterate — “Make the hero section dark mode” — or open the Monaco editor to tweak code by hand.
  5. Visual edit — click any element in the preview to instantly edit text, colors, or properties.
  6. Collaborate in real time using Yjs CRDT (cursors, selections, edits sync instantly).
  7. Publish with one click to a *.doable.me subdomain or your own custom domain.

What does Doable include out of the box?

  • A Next.js 15 frontend (React 19, Tailwind 4, Monaco editor, Yjs).
  • A Hono REST API for auth, projects, billing, AI chat, integrations.

  • A PostgreSQL schema with pgvector, pgcrypto, pg_trgm.
