OpenRouter made single-API access to hundreds of models easy, but it comes with trade-offs: markup fees on credits and on bring-your-own-key usage past a free cap, no self-hosting option, and a catalog that's almost entirely text-based LLMs. Which alternative fits depends less on features and more on one question: do you want to self-host, use a managed service, or pay as you go with no infrastructure at all?
