Tools for a
Freer Internet.
Everything you need to own your digital identity, protect your data, and take back control from the platforms.
Free Forever
Flowsta Identity
The foundation of everything you do on Flowsta — and across an open ecosystem of apps. One sovereign identity for signing in, signing files, and any new app built on the standard.
Not another login. The heart of a new internet.
Centralised digital ID puts a middleman between you and who you are. Flowsta removes that. Your identity lives on a distributed network — powering Sign It, future Flowsta apps, third-party developers, and anything else built on the standard.
Zero-Knowledge
Mathematically impossible for anyone to access your data — not even Flowsta staff.
Truly Yours
Your identity belongs to you. No corporation owns it, controls it, or can take it away.
One Identity, Everywhere
Sign in with Flowsta on a growing number of websites and desktop apps.
Decentralized
Powered by Holochain — no central server to hack, no single point of failure.
Document Signing
Sign It
Sign your work. Prove it's yours. Anyone can verify — no platform owns it.
Cryptographically sign any file. Your signature, content rights and AI training policy travel with the file — and anyone can verify by dropping it on a free public page.
Desktop App
Flowsta Vault
Your sovereign hub on your desktop. Manage your identity, sign your files with Sign It, and run third-party Holochain apps.
Vault keeps your private keys on your machine — never on a server. The 24-word recovery phrase you use to set it up is never stored at all.
Sign your files with Sign It
Cryptographically sign any file. Declare your rights, AI policy and authorship — all from the same desktop app.
Run third-party Holochain apps
Vault hosts a local conductor. Apps install side-by-side with your identity, and you approve every connection.
Offline desktop logins
Sign in to Holochain apps on your machine without an internet connection. Your identity is on disk, not on someone else's server.
One identity, every device
Cryptographically link your desktop vault to your web account. Same identity in your browser, on your phone, and in Vault.
