Atlas backs up browser profiles across your system and keeps everything stored locally for full offline control.
Every operation is validated before it runs. No hidden writes or surprises. Just reliable archiving.
Atlas runs entirely in user space. No elevated permissions needed, no system-level access required.
Zero writes to any browser directory, ever.
Space check, profile scan, and size estimate all run before a single byte is written.
Archives write to a .zip.tmp file, then
atomically rename on success. No corrupt partials.
No network calls. No telemetry. No analytics. What runs on your machine stays on your machine.
Cancel mid-operation at any point of the backup.
The pipeline never touches disk until all prior checks pass. Each step is independently cancellable.
From Mosaic-era relics to today's nightly dev builds — if it stores a profile, Atlas finds it.
Atlas works across a wide range of browser environments.
Every release, documented in full.
Zero external dependencies. Just Qt, Python, and the standard library.
