E2E testing platform that writes and runs tests in plain English across UI, API, CLI, and mobile, continuously adapting as the product changes.
Lark automates end-to-end testing by allowing teams to write tests in plain English instead of code, making them easier to maintain and more robust when the product changes. Tests run continuously across UI, APIs, SDKs, async workflows, and mobile, with native integrations to GitHub Actions, GitLab CI, and other CI tools. When tests fail, Lark sends alerts via Slack, email, or PagerDuty with logs, screenshots, and videos. Built by ex-Stripe engineers; provides first-class support for Claude Code, Cursor, and Codex. Lark is a product of Lark.
