The open-source LLM gateway that fixes your agents' requests on the fly
One OpenAI-compatible endpoint reaches every configured model, provider, subscription plan or local server.
Broken or non-conforming LLM requests are repaired automatically before the error reaches your agent or app.
Automatic retry on another provider when one goes down keeps agents and workflows running.
Track every request, token and dollar broken down by agent, key and provider, with full request and response body logs.
One OpenAI-compatible gateway for adaptive LLM routing, guardrails, and spend control
Each prompt is graded and routed to the model that clears your quality bar, with configurable fallback chains that retry before a response starts.
Pay provider prices with $0 per-token added on pay-as-you-go and subscriptions, or bring your own provider keys and credits.
PII shielding, jailbreak and injection blocking, and per-call approval for tool and MCP actions run before you are billed.
Request logs, per-prompt receipts, routing and spend dashboards, and copy-as-cURL make every call auditable and attributable.
