Use the platform as just a proxy

Point your app at one endpoint, route requests through it, and stop there if that's all you need.

Proxy-only means you can

Route requests through one endpoint

Swap providers without changing app code

Keep model names stable with aliases

Turn on tracing, routing, or security later

You do not have to

Adopt every feature on day one

Run extra services or infrastructure

Set up Docker, Redis, or Postgres first

Start with the core stack free

16Providers, One EndpointRoute requests across OpenAI, Anthropic, Google, Groq, Mistral, and 11 more through a single URL.

✓Tracing From First RequestSee cost, latency, and token usage on every request. No setup beyond install.

✓Runtime ControlsCaching, rate limits, PII redaction, and safety filters you can toggle without redeploying.

Self-hosted · Source available · Unlimited requests

76 Middleware Modules

Toggle what you need. Ignore what you don't.

Every module is a config flag. Enable PII redaction, guardrails, auto-routing, or cost limits without redeploying.

Cost & routing

Auto-routes to the cheapest model that meets your quality floor. 100 free decisions/day.

Safety & guardrails

PII redaction, content filtering, injection detection, and output validation. Toggle per-route.

Replay & testing

Replay any logged request. Red-team your prompts. Stampede floods with synthetic traffic.

Prompt evolution

Breed optimizes prompt populations genetically. Verdikt gates outputs. Crucible scores confidence.

Caching & failover

Semantic caching cuts repeat costs. Local-plus-cloud fallback keeps you running when providers are down.

Audit & provenance

Brand logs every request to a hash-chained tamper-evident ledger. Export for compliance.
