I unironically like meta.ai better. It uses both Google and Bing for web searches, and is better at citing its sources.

My https://chatcraft.org offers free models and is open source. They start throttling under heavier usage tho.

Gonna add some free models with search in future

I've been using https://yaddle.ai. It's got a nicer UI, free to use, and has a lot of models to try.
