> Every AI system in your company. In one place. Under control.

Markdown copies of public Openlayer pages. Docs live on Mintlify.

## Product
- [Governance](https://www.openlayer.com/product.md): Prove every AI system is governed, not just documented. One system of record for all your AI, with policy enforced and evidence generated from intake to production.
- [Cost Controls](https://www.openlayer.com/product/cost-controls.md): Tie token spend to projects, teams, and business outcomes. Find the AI work with no business case, stop runaway spend, and bring portfolio-level cost controls to AI.
- [Development](https://www.openlayer.com/product/development.md): Easy to test. Fast to ship. Test prompts, models, and agents with the SDK, CLI, and Git workflow you already use.
- [Evaluation](https://www.openlayer.com/product/evaluation.md): Prove an AI change is better before you ship it. Evaluation for LLM, agent, RAG, and traditional ML systems. Measure quality, safety, and performance with 175+ ready-to-use tests and governance built in.
- [Gateway](https://www.openlayer.com/product/gateway.md): The Openlayer Gateway captures every LLM call at the network level and routes it through one point of control. Discover shadow AI automatically, enforce policy inline, and trace every request without wiring up each service by hand.
- [Guardrails](https://www.openlayer.com/product/guardrails.md): Real-time guardrails that block prompt injection, PII/PHI leakage, and harmful outputs inline. Enforce security and compliance policy at runtime, not in a document written after the incident.
- [Monitoring](https://www.openlayer.com/product/monitoring.md): Know how your AI behaves in production, every minute it runs. Openlayer traces, tests, and monitors every production request with the same suite that gates deployment, so quality, cost, and compliance never drift out of sight.
- [Testing](https://www.openlayer.com/product/testing.md): Catch unsafe AI in your pipeline, not in production. Git-native, CI/CD-integrated testing for AI systems. Block unsafe deployments before they ship with 175+ tests, pre-built bundles, and the same suite that monitors production.
