One gateway, explicit governance
Authenticate with gateway keys, apply plan and budget policy, and keep the request path consistent for your application.
EU control plane for BYOK AI
Govern every model call without surrendering provider control.
Built for European software teams that need one OpenAI-compatible endpoint, enforced project budgets, understandable diagnostics, and provider billing that stays on their own accounts.

What the product actually does
Operational controls that stay close to the real architecture
BYOK without shared billing
Customer traffic still bills against the customer's own provider account rather than a pooled platform key.
Ordered failover
Team plans can define provider order so requests keep moving when a preferred model path is unavailable.
Hard spend ceilings
Project budgets are enforced on the request path instead of being decorative dashboard numbers.
Diagnostics people can use
Review usage, request duration, token counts, and fallback reasons per request without exposing prompts or secrets.
EU-hosted control plane
Keep gateway configuration, team controls, budgets, and diagnostics on European infrastructure. Upstream inference location remains determined by the provider account and endpoint you choose.
How teams work through it
A concise flow from provider key to governed production traffic
Connect provider credentials
Add your OpenAI or Anthropic key once, then keep that boundary separate from your application runtime credentials.
Issue app-facing gateway keys
Give each environment a scoped key and direct existing SDK traffic at the OpenAI-compatible endpoint.
Operate with budgets and diagnostics
Watch request health, review activity, and control fallback order without changing the application contract again.
Start with the real product surface
Free tier: one project, two keys, seven days of retention.
No card required. Create an account, add a provider key, and send your first request through the gateway.
