Quickstart

Complete walkthrough from installation to your first Agent task.

Step 1: Install the VS Code Extension

Search for Cooder in the VS Code Marketplace, or install directly:

→ Install Cooder on VS Code Marketplace

After installation, make sure GitHub Copilot is installed and enabled — Cooder works through Copilot Chat.

Step 2: Create an Account

1. Open your mobile browser and visit cooder.co
2. Click Sign Up in the top right and register with your email
3. Verify your email, then sign in

GitHub login is also supported for one-click sign-in.

Step 3: Add a Device (Pairing)

1. In VS Code, open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
2. Run Cooder: Generate Connection Token
3. Copy the displayed Relay URL and Token
4. In the Cooder app, tap Add Device, paste the Relay URL and Token
5. Once your device appears in the list, pairing is complete ✓

QR Code Pairing

In the Cooder app, select Scan QR Code and scan the QR code displayed in VS Code. One step, done.

Note: Both PWA and native clients require camera permission for QR login, device pairing, and payment flows.

Step 4: Start Your First Task from Your Phone

1. In the Cooder app, tap your paired device to enter the device view

2. Tap + to create a new Agent session

3. In the input box at the bottom, describe what you want the AI to do:

   implement user login with email/password and GitHub OAuth

4. Tap Send — the VS Code extension receives the instruction and starts executing immediately

Step 5: Watch the Logs in Real Time

After sending, the session view streams the Agent's execution live:

• Tool call records: which files were read, created, or modified
• Reasoning output: the AI's analysis and decision-making
• Progress status: current round number, completion, or errors

You can send follow-up instructions anytime (e.g., "also add rate limiting") and the Agent responds in real time. Once complete, a done marker appears — head back to VS Code to review the diff.

• Web (PWA): Visit cooder.co — works in any mobile browser, add to home screen. Recommended for iOS users.

Q: Do I need to set up a Relay Server?
