Coding sessions: environments, browser use, and updated pricing

Linear's coding sessions can now set up, run, and test code before returning it. Sessions detect and install dependencies, and you can create an environment in settings to pin runtime versions, add setup scripts, and define environment variables.

Once the app is running, the agent can test a flow in the browser and capture before-and-after screenshots. If it finds a problem, it can fix it and rerun the test.

Pricing now combines model usage at the provider's published rates, with no markup, and sandbox runtime at $0.25 per 20-minute block. Admins can set workspace-wide or per-user spend limits that reset daily, weekly, or monthly.
