Quickstart

Getting Sinatra running takes a few minutes. There's nothing to deploy — sign in, connect your tools, and assign an issue, mention Sinatra in Slack, or start a task from your terminal.

1. Sign in

Go to app.sinatra.dev and continue with GitHub, or enter your email to get a one-time sign-in link. The link works once and expires after 15 minutes, and a new address gets its account only when you use the link. For a new account, the page it opens lets you choose a password, so next time you can sign in with your email and password instead of waiting for a link; an existing email account can set one from Forgot password?. See Signing in. If your team already has a Sinatra workspace, accept its invitation or request access. Otherwise, continue to the GitHub App installation step to create one.

2. Install the GitHub App

From the dashboard, install the Sinatra GitHub App on the organization (or personal account) whose repos you want Sinatra to work in, and pick the repositories it can access. A new installation creates a workspace for that GitHub account. In the workspace's Repos tab, enable the repositories Sinatra should work on.

On an organization, you need write access to every repository the installation covers, as an organization owner has; otherwise Sinatra doesn't connect it. To install on your personal GitHub account after signing up by email, first use Link your GitHub account on the setup page, or Link GitHub in a workspace's Settings. You can also choose Start without GitHub to name a workspace now and connect GitHub from its settings later.

Installing the app requires permission on GitHub; changing shared Sinatra configuration requires the owner or admin role. See GitHub App for requested permissions. Sinatra works on branches and opens PRs; merging stays with you.

3. Connect Linear

An owner or admin can connect the Linear workspace from the dashboard. Each teammate who delegates work from Linear must also join the Sinatra workspace and use Link Linear identity in Settings. Authorize the same Linear organization that the workspace uses. See Linear setup.

You can skip Linear and run on GitHub issues alone.

To work from Slack too, an owner or admin connects it from Settings → Slack, then invites Sinatra to the channels you want to use. Sinatra matches each member's Slack account by email; anyone it can't match uses Sign in with Slack on the same card. See Slack.

4. Add model access

Every account, including existing and paid accounts, needs its own model credentials before delegating work. Each member can connect a personal subscription in Settings for their own tasks. An owner or admin can add a shared Anthropic or OpenRouter API key for authorized workspace members. A teammate's personal connection does not cover your tasks. See Models for all supported connections.

For reproducible setup, commit a .sinatrarc.json with dependency installation commands and your test command. You can also set personal agent preferences from Repos → repository.

5. Hand it an issue

Choose a small issue with a clear expected outcome. On Linear, assign it to Sinatra or @-mention Sinatra in a comment; name the target repository if it could be ambiguous. On GitHub, add the Sinatra label — sinatraai on the hosted app, provisioned on enabled repos. In Slack, mention @Sinatra in a channel with the request, adding repo: owner/name if the workspace has more than one repository.

Or start it from your terminal: run npm i -g sinatra.dev and sinatra login, approve the CLI in the browser page it opens, then run sinatra "fix the flaky retry test" inside a checkout of the repository you want it to work on. Claude Code and Cursor can start tasks too, through Sinatra's MCP server. See CLI, MCP and API.

If the issue is vague, Sinatra may first ask questions or propose a plan in an ordinary reply. Answer on the ticket, in the Slack thread, or in the task's conversation, adjust the plan, or tell it to go ahead. There is no separate approval step. During implementation it opens a draft PR, runs the configured test command after the agent finishes, and performs self-review. Check the reported results before merging. See How it works for review feedback and stopping a run.

Pricing

Free is 1 task at a time, plus 1 queued, with no daily limit and no card. Pro is $20 USD a month for the whole workspace: 3 tasks at a time, plus 10 queued, with as many people as you like. Team ($99) is 10 tasks at a time, plus 25 queued, and Scale ($249) is 25 tasks at a time, plus 100 queued. Assign as many tickets as you want. Your plan sets how many run at once; the rest are queued and start on their own as soon as one finishes. If the queue is full, Sinatra says so on the ticket instead of starting it. On Free, each request runs for up to 60 minutes. Sinatra never bills for model usage; your provider's charges and usage limits apply separately. See Billing for every plan, how the queue works, and Enterprise terms.
