One-line integration. Zero risk.

Cut your LLM API
bill by 60%

Kestrel routes each request to the cheapest model that can handle it. You pay 15% of what we save you. If we save nothing, you pay nothing.

One line to integrate

Change your base URL. Everything else stays the same.

from openai import OpenAI

client = OpenAI(
  base_url="https://api.usekestrel.io/v1",
  api_key="ks-your-key",
)

# Your existing code works unchanged
response = client.chat.completions.create(
  model="gpt-4o",
  messages=[{"role": "user", "content": "Hello"}],
)

Built for trust

Encrypted at rest

Your provider API keys are encrypted with AES-256 before storage. We never log prompt content or responses.

HTTPS everywhere

All traffic is encrypted in transit. API, dashboard, and webhooks all enforce TLS.

Your keys, your control

You bring your own provider API keys. Revoke access instantly from the dashboard at any time.

Isolated by design

Each customer's cache and data is isolated. No cross-tenant data access is possible.

Start saving in under a minute

Sign up, add your provider keys, change one line of code. That's it.
