Pricing
Simple, usage-based pricing
Start free and scale as your test suites grow. Every plan includes valid checksums and deterministic seeds.
Edge-case mode
Flip one flag and every record is drawn from the awkward-but-valid corners of the format — the leap-year dates, maximum-length names, rare-but-legal identifiers that quietly break naive validators. The bugs your fixtures never hit.
Extreme mode
The next step beyond edge: correct values wrapped in the most hostile encoding a real system ever sees — untrimmed whitespace, invisible and zero-width characters, homoglyph lookalikes, right-to-left overrides. Answers the question your validators never ask: does your pipeline trim, normalise, and compare safely?
