One unified API gateway for a vast range of AI models
Route requests to many upstream AI models through one standard, OpenAI-compatible API protocol, so your code stays the same as providers change.
High-concurrency handling with automatic load balancing spreads traffic across your configured channels to keep responses reliable.
Pay-as-you-go accounting with real-time usage monitoring and clear per-key, per-model spending so you always know where budget goes.
Add API keys, set up channels, and assign access permissions for multiple users from one central admin panel.
One open-source AI gateway for 100+ LLM providers
Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
Provides a massive hosted model catalog with instant access, but requires trusting a third-party platform instead of self-hosting.
