Praxa

Praxa provides a robust logging layer for high-risk systems, ensuring compliance with regulations such as the EU Act Article 12, which mandates per-event logging and at least six months of data retention starting August 2, 2026. Key features include: • Per-event logging of every decision • Tamper-evident SHA-256 hash chains • Auditor-verifiable evidence packs • Integrations with major model frameworks (OpenAI, Anthropic, LangChain) Praxa automatically records every decision, including input, score, rationale, and downstream actions, into a secure, forward-only hash chain. This design ensures that any alteration or deletion of a record immediately breaks chain continuity, providing verifiable integrity. The platform simplifies regulatory compliance by generating auditor-ready evidence packs in markdown or JSON format, directly verifiable without needing a Praxa account. This tool is ideal for engineering teams and businesses deploying high-risk systems in sectors like hiring, lending, insurance, or biometric identification. It addresses the critical need for transparent, verifiable records of system operations, helping organizations meet strict compliance deadlines and avoid liabilities. Praxa offers a free tier for up to 10,000 decisions per month, with paid options for higher volumes.
