Openrouter
Open-source platform for routing LLM-based requests and managing AI agent interactions efficiently.
A near-essential unified gateway to hundreds of LLMs with no token markup; you pay a small credit-purchase fee for the convenience and reliability.
Community ratings
Third-party ratings shown verbatim; aggregate weighted by review volume.
A unified API that routes requests to 300+ LLMs from 60+ providers through one key and bill - with no markup on token pricing, plus automatic fallbacks and usage analytics.
It solves provider sprawl elegantly: one integration to reach Anthropic, OpenAI, Google, Meta, DeepSeek and many more, with pooled uptime/failover, per-request cost metadata, consolidated billing and even free model options. The catch isn't a subscription - it's a 5.5% fee on credit purchases (token rates match providers exactly), plus a BYOK fee above a generous free-request threshold.
