Code with confidence.

Speed up your feedback loops

Code with Clarity syntax support, run tests, and debug your code line by line, using a powerful command line interface.

Increase your code coverage

Tests don’t have to be tedious. Pummel your source code with unit tests, make sure your contracts function, and unleash a swarm of integration tests with the Clarinet SDK.

Run a private blockchain environment

Run end-to-end tests on a fully private blockchain environment with dedicated nodes, miners, and APIs. It's the closest thing you can get to testnet, without exposing your contracts to the world.

Improve code quality

Ship code your CompSci prof would be proud of. Catch errors and typos right away with Clarinet’s linter and other helper tools, and make your code easy to read with the Clarity formatter.
