Everything you need to know about Luvian plans.
Instead of locking your work inside Luvian, we save your designs as files in a GitHub account that you own. You keep the full history of every change, your team's existing review process still works, and you can leave at any time without losing data. Free uses GitHub. Pro and above also let you use our cloud workspace if you'd rather not manage Git yourself.
Coverage analysis tells you whether your design actually meets every requirement you set out to satisfy — so nothing slips through the cracks before testing. Luvian checks coverage across seven angles: structure, behavior, interfaces, performance, safety, security, and verification. Pro plans cover the first four; Team and Enterprise plans check all seven.
Anything you ask the AI to do — generate a design block, rewrite a requirement, suggest a hazard — counts as one request. Background AI assistance (included on Team and above) runs quietly while you work and doesn't count against your quota. Enterprise customers can plug in their own AI and remove the limit altogether.
Yes. Pro and above can move either direction whenever you want. Because your work lives in standard files, switching is a one-click change with no data loss.
Accredited universities, K-12 STEM programs, INCOSE and SAE student chapters, and open-source safety projects (such as openpilot, F′ / F Prime, and Apollo Auto). You fill out a short application and renew it once a year. Exports carry a small “Luvian for Education” watermark.
Enterprise customers get a complete document set ready to hand to an auditor. Each pack pulls together your design, requirements, hazards, trade-off studies, and tests into the format that automotive (ISO 26262, ISO 21434), aerospace (ARP4754A, DO-178C), and medical (IEC 62304) assessors expect. No more chasing artifacts the night before an audit.
Yes — annual billing saves 20% on Pro and Team. Enterprise contracts are quoted yearly and include volume discounts above 25 seats.
Start free, invite your team when you're ready, and step up to audit-ready paperwork once you're shipping.
