ShareX is a free, open-source Windows-only capture tool that records screen and audio via FFmpeg and uploads to external services. It has no video editor, no hosting, no analytics, no Mac version — you configure upload targets and use other tools for everything after capture.

Tella records on Mac, Windows, and the browser, then handles the rest in one place: a full editor, AI auto-cut and auto-zoom, cloud hosting with analytics, embedded players, and team collaboration — no upload pipeline to configure.
