Ship with confidence: one system of record for manual, automated, and CI tests
Manual test cases, automated test runs, and CI pipeline results consolidate into one dashboard so there are no blind spots about coverage or pass rates.
Paste a manual test case, choose a framework, and Qase generates an automation script for Playwright, Cypress, or Selenium, shrinking the manual backlog instead of growing it.
Bidirectional links connect every requirement to its test cases and results, so when something breaks you can trace exactly what was verified.
Pass rates, coverage gaps, blockers, and flaky-test history come together in shareable readiness views for confident go/no-go decisions.

Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.
