Snap is not released. It is an early build with no installer on any platform. This page describes what exists so far and what is planned. See the roadmap for the current state feature by feature.
Snap is a screenshot tool built for people who document software: capture, organise, annotate, and hand the result to Compose as a ready-to-caption block.

Capture modes, the library, shortcuts.

What is built

An honest feature-by-feature status.

​
The idea

The library is a folder. A collection is a directory. A capture is an ordinary PNG. There is no database, no import step, and no proprietary container — you can open the whole library in a file manager, back it up with any tool, and keep every file if you uninstall Snap. Annotations are the one thing that cannot live inside a PNG, so they sit beside it in a small .snap.json file. The image itself stays a plain image any application can open; annotations are burned in only when a capture is exported, copied, or sent to Compose.

​
What works today

  • Region, whole-screen, window and delayed captures
  • A library view over your capture folder, with collections, filters, search and sorting
  • Global capture shortcuts that fire from the system tray with the window closed
  • Optional sign-in (not required for anything currently implemented)

​
What is not built yet

  • The annotation editor — numbered steps, callouts, spotlight, crop
  • Screen recording
  • Scrolling capture
  • Send to Compose
  • Cloud backup of the library

​
Platforms

Windows is the target. Snap builds and runs on Linux, and that build is maintained, but it is not shipped: a Wayland client is not permitted to read the screen, so the compositor owns the selection interface and region, window and full-screen capture all collapse into a single “let the user choose” prompt. That is a materially different product rather than a port.
