Open source · MIT

Your agent. Your infra. Your data.

LFG is fully open source. Run the entire AI product-development agent on your own server with Docker, bring your own model and API key, and keep every byte of your data in-house. No vendor lock-in.

Quick start

Up and running in one command

The default setup uses SQLite and local file storage, so there's nothing external to provision for local dev.

bash
# Clone and install (needs Bun)
git clone https://github.com/lfg-hq/lfg.git && cd lfg
bun install

# Configure: set BETTER_AUTH_SECRET + one AI provider key
cp example.env .env

# Start (runs migrations, serves on :3000)
bun run dev

Sandboxes

Run builds on your own machines

Every app the agent builds runs in an isolated sandbox. Choose where that compute lives.

Docker (self-hosted)

Each sandbox is an isolated Docker container on your own server, from a prebuilt image with Node, Python, and the coding agents baked in. No third-party compute, your code never leaves your box.

Managed VMs (hosted)

Prefer not to manage compute? Point LFG at hosted Firecracker micro-VMs and get public preview URLs out of the box. Flip a single env var to switch backends.

Bring your own model

Works with every major model

Use your own API keys. Switch models per task, cost, or capability, no provider lock-in.

Your database

SQLite out of the box, or point it at your own Postgres. Your data lives where you put it.

Your files

Store uploads on the local disk, or plug in S3. One env var flips between them.

Your keys

Secrets are encrypted at rest and stay on your infrastructure. Nothing phones home.

Managed hosting

Prefer we run it for you?

Don't want to manage the infrastructure? We offer fully managed, dedicated LFG instances, hosted, scaled, and maintained by us, with your models and isolated data. Tell us what you need and we'll set you up.

Custom deployments, SSO, SLAs, and volume pricing available on request.
