Open-source alternatives to Portkey

Portkey is a hosted AI gateway that sits between your application and LLM providers, adding routing, observability, and guardrails behind a unified API — priced on a per-log basis with a free tier capped at 10,000 logs a month and paid tiers starting at $49/month. Portkey was acquired by Palo Alto Networks in 2026, which has pushed some teams toward gateways they can run entirely on their own infrastructure instead.

LiteLLM is the closest self-hostable match, unifying 100+ LLM providers behind one API with spend tracking, without requiring you to route traffic through a third-party account. Proxed AI is a narrower option focused specifically on securing AI API calls from iOS apps.
