Not another AI app builder. the runtime that makes your agent's app real.
Your AI already builds the app. Synthonic makes it real.
Every AI builder hands you a stuck artifact — no state, no backend, no one to run it. Point your agent at a prompt, a CSV, even the spreadsheet you run on today; Synthonic turns the folder it writes into a real app: a database, a live URL, and an AI operator. You own what ships.
You need An AI agent you already use (Claude Code, Codex, any harness) and zero engineering. It writes the folder; Synthonic gives it a backend and an operator. New to AI agents? We'll walk you through it.

- views/board.jsoninterface
- policy.jsonrules

Same folder, now a real app: a database, a live URL, roles-based access — with an AI operator over MCP on the roadmap. Bring any agent. No React, no backend to wire.
Every business runs on tools that don't exist yet: the tracker, the intake form, the little CRM. Getting one meant waiting on engineering you don't have, and AI still just hands you a stuck artifact. Synthonic makes it a real app you run, and it's yours.
redline resolves the note: an idea a non-engineer can ship, no backlogFrom stuck artifact to running app.
You already do the first step inside your harness. Synthonic picks up the folder your agent writes and gives it the state, backend, and operator a static artifact never had.
It writes a folder, not an artifact
In Claude Code or any harness, describe the tool, or just hand it the CSV or spreadsheet you already keep. Your agent writes a small folder of data (schema, views, rules, an AI persona) instead of a one-off that stops at the canvas.
It gains state and a backend
One generic engine turns that folder into a real database and interface with persistent state: the functionality the artifact was missing. It's a versioned folder, so teammates and other agents can build on it with you. Nobody writes React or Go.
People and AI run it together
Live at a URL from turn one. Share it with your team — each signed in as the member and role you list. Connecting an AI collaborator over MCP is on the roadmap; the access model already reserves an agent role for it.
LLM-first: the artifact was only ever half the tool.
A generated artifact is a frozen front end. Synthonic makes every app the same kind of thing, a folder a generic engine reads, so it ships with the state, the backend, and the AI operator that make it a tool your team can actually run.
/mcpRoadmap The direction that defines Synthonic: every app will expose a standards-based MCP interface any AI collaborator can drive — Claude, ChatGPT, Codex, any MCP client — bounded by a default-deny policy, so the tool isn't just built by AI but run by one. It's on the roadmap, not shipping yet; the access model already carries an agent role built for it.
persistent A database, validation, and durable records sit behind the interface, not a stateless canvas. Your data lives, survives a refresh, and keeps its shape as the app changes.
no localhost No "run it on your machine" step to reason about. You build, it's hosted, here's the link. Draft to production on the same folder.
reconcile Edit the folder, redeploy. A failed build is the gate, with the errors to fix. Automatic snapshots of production data before every change are on the roadmap. Iteration doesn't accrue debt.
one folder One app, shared two ways today: build it together (the versioned folder, people and agents side by side) and let your team operate it (the live URL). Letting an AI collaborator operate it too — over MCP, bounded by policy — is on the roadmap. Solo grows into a team, no rebuild.
Watch a stuck artifact become a running app.
A walkthrough, end to end: describe the tool to your AI agent, and Synthonic turns it into a real app you run and share. No engineering team, no backlog, no infra.
Skip the waitlist. Use the beta.
Synthonic is an early, honest beta. The CLI is rough and it can break. There's no gate: you start as a guest, no signup, and the coding agent you already use drives it.
- No waitlist, no gate. Guest by default, no signup.
- macOS for now (Apple Silicon or Intel). Other platforms soon.
- Rough edges are expected. Things break, and we fix them fast.
- Built and run with the agent you already have.

synthonic init feedback-board
✓ Created feedback-board — describe your tool to your agent
# …your agent edits the folder, then:
synthonic deploy
