Download Atlas
Choose your platform. Available as an installer or a standalone portable .exe.
Atlas backs up profiles from 250+ browsers — nightly builds, obscure forks, UWP packages, Flatpak, Snap, and beyond. Fully offline. Fully yours.
Every operation is validated before it runs. No hidden writes. No surprises. Just reliable archiving.
Atlas runs entirely in user space. No elevated permissions needed, no system-level access required.
Profiles are never modified. 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 stage. Temp files are cleaned up, no state is left behind.
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.
The surface area Atlas covers is hard to overstate.
Every release, documented in full.
Zero external dependencies. Just Qt, Python, and the standard library.
