Coding sessions: environments, browser use, and updated pricing

Linear Agent can now set up, run, and test your code before returning its work. That means fewer handoffs and changes that are further along when they come back to you.

We’re also introducing lower, more transparent pricing, making AI credit usage easier to understand and control.

Configurable environments

Coding sessions now automatically adapt to each codebase's configuration, with broader out-of-the-box support for Python, Ruby, Go, and more.

During a session, Linear detects and installs the toolchains and dependencies it needs to complete the task. Teams can go further by pinning runtime versions, adding setup scripts, and defining environment variables.

To get started, create an environment in settings. Visit the docs for more details.

Browser testing

Once the application is running, Linear Agent tests its work where users experience it: in the browser.

The agent opens the app, navigates through a flow, and verifies its implementation. It also captures before-and-after screenshots, making visual changes easier to review alongside the code.

Browser testing can catch broken interactions and visual regressions that code review alone might miss. If the agent finds a problem, it can make a fix, rerun the test, and return the work with that validation complete.

Transparent pricing

As coding sessions take on more work, costs need to be easy to understand and easy to control.

Starting today, coding sessions use a lower-cost pricing model with two components:

Model usage: Tokens are charged at the provider’s published rates, with no markup

Sandbox runtime: Charged at $0.25 per 20-minute block

Together, model usage and runtime determine the AI credit cost of a session. The usage dashboard shows the breakdown, along with token usage and cost by model.

Admins can also set workspace-wide and per-user spend limits that reset daily, weekly, or monthly. When a limit is reached, additional AI credit usage is paused until the limit resets or an admin increases it.
