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.
The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
Provides a massive hosted model catalog with instant access, but requires trusting a third-party platform instead of self-hosting.
