LiteLLM
the widest provider coverage, with the governance behind a paywall
the broadest coverage of any self-hostable gateway, but the features most teams deploy it for sit under a proprietary licence with no published price.
litellm's readme promises 'a single, unified interface to call 100+ llm providers ... using the openai format', and that breadth is the reason it is everywhere. self-hosted, it adds no per-token cost — your keys, your compute, provider bills direct at list. virtual keys, per-project spend tracking, load balancing, retry and fallback routing, and the admin dashboard all work on the free mit core.
the licence is where it gets complicated, and litellm is at least honest about it. the root licence file is mit but explicitly states that everything under the 'enterprise/' directory is governed by a separate licence, and that file is a proprietary berriai enterprise licence requiring 'a valid berriai enterprise license for the correct number of user seats' for production use. development and testing are permitted unlicensed.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
