From my understanding, Browserbase mostly provides remote browsers for their users. We also provide remote browsers, but with a lot more infrastructure on top (single/multi web agents, caching/reliability support, an agentic IDE/editor, etc).
not really sure how that differentiates since those things you mentioned are ancillary to main value. Also - browser base is insanely cheaper, but looking at the prices this doesn't look like a real company mainly just a way to have users in free tier (with toy level limits)
