PDF editing and markup

Butter Paper

Butter Paper is a free, open-source PDF editor and markup app for macOS, Windows, and Linux, built natively in Rust with GPUI. It also acts as an alternative to Bluebeam Revu for architecture, engineering, and construction workflows.

Beta builds get new features first and can be less stable. Butter Paper Beta installs alongside Butter Paper and is available for macOS only.
