Attestly vs Openlayer

These solve different-sized problems. Openlayer is a full AI evaluation, testing, and observability platform that also addresses EU AI Act compliance as one of its use cases. Attestly does one thing: Annex IV documentation for AI agents, generated from their runtime traces.

Openlayer integrates into CI/CD pipelines to run evaluations on every model or prompt change, and offers observability, tracing, alerting, and a model-testing library across any ML or LLM system — not agents specifically. Its free Basic plan (20,000 inferences/month, one workspace) covers the core evaluation and observability tooling. Compliance reporting, custom regulatory mappings, and the deeper governance features sit in the Enterprise plan, which is custom-quoted and sales-led (“Contact sales”, no self-serve pricing published).

Attestly doesn't do model evaluation, testing, or general observability — there's no dashboard for prompt performance or model drift. What it does is narrower: read agent runtime traces and draft the Annex IV documentation sections (monitoring, human oversight, change log) with evidence links back to specific events, available starting on the free tier.

Where each one fits better

If you need a single platform to evaluate and monitor AI/ML systems broadly — accuracy testing, drift detection, prompt evaluation — across an organization with the scale to justify an enterprise governance contract, Openlayer's platform covers far more ground than Attestly attempts to.

If what you actually need is the Annex IV documentation itself, specifically for an AI agent, without adopting a full evaluation platform or a custom enterprise quote to get the compliance-relevant features — that's the narrower job Attestly is built for. See what Annex IV actually requires if you're scoping which approach fits.
