Whereby

Whereby (formerly appear.in) is a famously simple, browser-based tool that requires no downloads or accounts for guests. It emphasizes ease of use and the ability to create permanent, custom-named meeting rooms (e.g., whereby.com/yourteam). For large teams on its Business plan, it supports up to 100 participants and includes features like meeting recording, live streaming to YouTube, and integrations with Miro, Mural, and Google Drive. While it lacks some advanced enterprise features, its simplicity and reliability are its hallmarks.

It ranks for its frictionless user experience, strong performance directly in the browser, and appeal for teams that prioritize quick, hassle-free collaboration.
