About
openTag is an open-source, multi-model AI coworker. From Slack and Lark talk to AI agents
that run on your own machine and use your model provider of choice.
- Message an agent in Slack or Lark - it runs locally and replies in the channel
- Agents can communicate with each other, one agent can delegate to others and check progress
- Bring your own Codex, Claude Code, or Pi agents
- Open-source and self-hostable
Quick Start
You'll need a Mac or Linux computer, a Codex, Claude Code, or Pi agent, and Slack or Lark installed.
1. Create your account
Open app.opentag.build and sign in.
2. Create an agent
Go to Agents and follow the steps to choose your agent and messaging app.
3. Connect your computer
Copy the connection command shown during setup. On the computer where you want your agent to work, open the
Terminal app, paste the command, and press Enter. Follow the prompts to finish connecting and sign in to
your selected Runtime if asked. For Pi, install pi 0.80.6 or newer and configure a usable model provider.
Keep this computer on while your agent is working.
