Simple setup
Up and running in minutes
Add your provider keys
Securely store your OpenAI, Anthropic, Mistral, or Cohere API keys. Encrypted with AES-256-GCM at rest.
Point your app to the proxy
Change one line: swap the base URL in your SDK to your Llummo instance. No other code changes needed.
Watch costs in real-time
Every request is logged with token counts, cost, model, route, and function name. Anomalies are flagged instantly.
Everything you need
Full visibility. Full control.
Multi-Provider Proxy
One endpoint for OpenAI, Anthropic, Mistral, and Cohere. Streaming and non-streaming — all transparently proxied.
Real-Time Cost Tracking
Every token logged. Daily charts, per-model breakdowns, and linear month-end projections.
Anomaly Detection
Auto-alerts when costs spike, plus optional hard spending limits — block requests at the proxy before the bill climbs.
Hard Spend Caps
Set daily or monthly limits. Block requests at the proxy the moment your cap is hit — no more end-of-month surprises.
Encrypted Key Storage
Provider keys stored AES-256-GCM encrypted. Never exposed in the UI beyond the last 4 characters.
Proxy Key System
Issue separate bearer tokens for each app. Real API keys never leave the server.
Usage by Route & Function
Tag requests with route, function, and prompt version. Track cost changes across prompt iterations — see exactly which version is cheaper.
Per-Customer Cost Attribution
Tag requests with a customer ID. See exactly which of your users is costing you the most.
Agent Trace View
Group all LLM calls in one agent run under a single trace ID. See the full call chain, cumulative cost, and duration in one view.
Prompt Version Tracking
Tag requests with a prompt version label. Track cost changes across prompt iterations — see exactly which version is cheaper.
Shareable Budget Link
Share a live, read-only cost summary with your team, CFO, or clients. One link, no login required.
Zero friction
One line. That's it.
Swap the base URL in your OpenAI SDK. Llummo intercepts, logs, and forwards every request transparently. No wrappers, no SDK changes, no behavior difference.
- Streaming and non-streaming fully supported
