Open-source Loom with automatic cursor-follow zoom — an amateur screencast that looks funded.

▶Repo detailsthe review · specs · pros & cons

What it is

A desktop screen recorder that captures your screen and webcam and produces a shareable link, in the mould of Loom. Its distinguishing trick is automatic zoom: it follows your cursor and pushes in on whatever you are clicking, without you editing a single keyframe.

What it is good for. Anyone selling something that is hard to describe in a sentence. Some ideas land in a video and die in a paragraph, and everything else in the marketing depends on someone understanding the product first. This is not about replacing an editing suite — it is about the twenty other recordings nobody opens an editing suite for: a reply to a support question, a feature teaser, a clip for a cold email. The auto-zoom removes the exact step that makes those feel cheap, and because the share link reports who watched and how far, a demo becomes a measurable marketing asset rather than a file.

Good
  • Cursor-follow zoom is genuinely automatic — the polish costs you no editing time
  • Share links carry view analytics, so a demo becomes a number and not just a file
  • Self-hostable if you ever want the videos on a machine you control instead of theirs
Watch for
  • Overlaps SnagIt and Camtasia — it adds a fourth recorder rather than replacing three
  • AGPL-3.0 on the main app. Fine as a tool you use; read it before embedding anything
  • The cloud tier is where the sharing lives; self-hosting the sharing half is real work
Works well with

Later it can run self-hosted alongside your other containers (see Coolify, 08) so demo links live on your own domain.
