Lot

Quick Start

Get from sign-up to your first AI-powered coding session in a few minutes.

1. Sign up

Head to lot.dev and sign up with Google, GitHub, or email. You'll get a free $5 credit to get started.

2. Connect GitHub

After signing in, you'll be prompted to connect your GitHub account. This installs the Lot GitHub App on the repositories you choose. Lot needs read access to clone your repo and write access to push branches and create PRs.

3. Add your Claude credential

In the workspace sidebar, click your avatar and go to credentials. Add either a Claude Pro/Max subscription token or an Anthropic API key. This is what powers the AI agent in your sessions.

  • Claude subscription token — use your existing Claude Pro or Max subscription. Best if you already have a subscription.
  • Anthropic API key — pay-per-use via the Anthropic API. Best for teams or heavy usage.

4. Create a project

Click New Project in the sidebar. Select one of your GitHub repositories and the branch to work from. Choose a sandbox size:

  • Small (2 vCPU, 4 GB) — good for most projects
  • Large (4 vCPU, 8 GB) — recommended for Next.js apps or if you want auto browser verification

5. Wait for setup

After creating the project, Lot spins up a setup session. An AI agent will:

  1. Clone your repository
  2. Detect your stack and install runtimes (Node.js, Python, etc.)
  3. Install dependencies
  4. Configure the dev server command and port
  5. Take a snapshot of the environment

This typically takes 2-5 minutes. You can watch the setup agent work in real time. Once complete, all future sessions boot from this snapshot in seconds.

6. Start coding

Click New Session on your project. The sandbox boots from the snapshot, starts your dev server, and the agent is ready. Type a message to start:

Add a dark mode toggle to the settings page

Watch the agent work, review the diff in the Diff tab, see the live preview update, and when you're happy, click Create PR to send a pull request to GitHub.
