OpenSave, a tool for peer-to-peer synchronization of game saves between devices, has been released in version v2.3.0.
After moving to a project-owned relay in version 2.2.3, 2.3.0 now adds dedicated save detection for Linux and Steam Deck along with an OS-aware updater. It also brings streaming support for large files and optional pre-release builds for anyone who wants to test in-progress work.
release: 2.3.0 - Steam Deck & Linux save detection, pre-release support, large-file streaming
Adds save detection and an OS-aware updater for Steam Deck and Linux installs. The desktop app can now offer pre-release builds for users who want to test in-progress work before it ships. A QA pass hardens track-path safety, the file watcher lock, and snapshot resilience, and adds streaming support for large save files.
