Open WebUI fits multi-LLM compare demand

This is just a Reddit help thread, but it captures a real shift in AI tooling: developers no longer want one “best” model, they want a repeatable way to compare several on the same task.

• –Open WebUI is the best match for the post’s BYO-keys angle because it supports OpenAI-compatible APIs, multiple providers, concurrent model use, and many-model chat features
• –OpenRouter now has a polished chat playground for side-by-side model comparisons, but it is more of a hosted aggregation layer than a bring-your-own-subscriptions dashboard
• –The strongest unmet need is not model access but evaluation UX: saved prompt suites, four-model layouts, scoring, and reusable comparison sessions
• –Threads like this are a useful signal that multi-model benchmarking is moving from hobbyist curiosity into a normal developer workflow
