| What makes it different | - One endpoint replaces every client config, eliminating need for each client to store every server and secret
- Coding agent builds the server automatically with no adapter needed
- Credentials held once by Rayrun instead of distributed across clients
- Built-in security review with published controls and audit trails for compliance teams
- Support for multiple service types without writing adapters
| - Bounded prompt under a fixed cap while history grows, so costs per call stop climbing on long sessions
- Every run recorded with cryptographic proof: rebuilable prompts, hash-chained journal, re-runnable engine
- Resumes from crash without repeating finished actions using stable idempotency keys
- Budget enforcement before each model call, not reactive overage billing
- No model key storage or logging; your provider bills you directly
