Key features	AI-generated Playwright and API tests from real user sessions Automatic test healing in real time as the application changes Human engineer verification before any test is marked ready Generated tests run as standard Playwright code in the team's own repo No per-seat or per-run fees, priced only by workflows maintained	Formal verification proving functional equivalence, not just plausible output Auto-generated test suites reaching full MCDC coverage Static analysis segments codebases into independently verifiable components Supports C++, Python, VHDL, CUDA, Rust, and other systems languages Reports reducing manual coding time by at least 80% on qualifying work
Pros	Human verification adds a real reliability check beyond pure AI output Usage-based pricing avoids per-seat costs as a team scales A bootstrapped, revenue-generating company rather than a pre-revenue startup	Formal verification addresses certification requirements general coding tools ignore Real traction in defense and aerospace, not just a stated ambition Supports systems-level languages most AI coding tools don't touch
Cons	No self-serve trial or published pricing; every deal starts with a demo Only a LinkedIn company presence was found, no other public social account Relies on Playwright specifically, so teams on a different test framework aren't served	Pricing isn't published, requires a sales conversation Narrow focus on regulated, safety-critical industries limits general applicability Less relevant to a team writing standard web or application code
