Sinatra
A ticket-taking coding agent that runs on your Claude or ChatGPT subscription.
Sinatra (sinatra.dev) is a coding agent that takes tickets. Users assign it a Linear issue, label a GitHub issue, mention it in Slack or start a task from the terminal. It checks out the repo in its own sandbox, makes the change, runs the tests with two tries to fix failures, and opens a draft PR with a summary and its own review notes, pushing fixes when reviewers comment. Models run on the user's Claude or ChatGPT subscription or an API key, and a committed .sinatrarc.json can pin the test command, model, engine or reasoning effort. The free tier runs one agent at a time; Pro ($20/month) runs three.
