Everything your files need, nothing they don't.
CattStack is built around one idea: storage should protect your work, not hold it hostage. Here's what you get in every vault.
Continuous sync
A lightweight desktop agent watches your folders and seals changes the moment you save. Conflicts are versioned, never overwritten, so two people editing the same file both keep their work.
Selective & smart sync
Keep your whole library in the cloud and pull down only what you touch. Recently used files stay warm on disk; the rest free up space automatically.
Point-in-time recovery
Restore a single file or an entire vault to any moment in the last 90 days. Ransomware and fat-fingered deletes stop being emergencies.
Expiring share links
Send a link that dies on a date you pick, caps its download count, and can require a passphrase. Revoke it any time from the dashboard.
Local full-text search
Find that contract by a phrase inside it. Indexing runs on your device, so the words in your documents never touch our servers.
Team roles & audit trail
Owner, editor, and viewer roles per vault, plus a tamper-evident log of who opened, changed, or shared what — exportable for compliance.
Works where you work
Native apps and a fast web client, all reading the same encrypted vault.
