Build the
New Internet.
Integrate Flowsta's self-sovereign identity for authentication and data privacy no one else can match — then layer on capabilities like file signing whenever you're ready. You focus on the features your users want; together, we build the New Internet.
Developer Solutions
Everything You Need to Ship
Start with identity — a login button for an app you have, or full Holochain integration for something new — then layer on the rest. Free to start, scale as you grow.
Sign in with Flowsta
The foundation everything builds on. OAuth 2.0 + PKCE authentication with a hosted login page — no client secrets needed. Your users get sovereign identity with zero-knowledge privacy and censorship resistance, out of the box.
OAuth Documentation →SDKs & Login Buttons
TypeScript-first SDK under 10kb. Pre-built login buttons for React, Vue, Qwik, and vanilla JS. Install with npm, authenticate in minutes.
SDK Documentation →Sign It API
Add cryptographic file signing and verification to your app. Users sign with their Flowsta identity — no keys to manage, no passwords to hash. Anyone can verify the result on the public Holochain DHT.
Sign It Documentation →Webhooks & Events
Subscribe to real-time events from your users' identities — new signatures, OAuth authorizations, profile updates. HMAC-signed payloads with a 10-second timeout. Auto-disabled after repeated failures.
Webhook Documentation →Vault Integration
Connect your Holochain app to Flowsta Vault for desktop identity. Agent linking, source chain backups, and IPC communication on localhost.
Vault Documentation →Developer Dashboard
Register apps, manage client IDs, view OAuth analytics and MAU tracking. Invite team members and manage roles from one place.

Choose Your Integration Path
Two ways to build with Flowsta: add sovereign identity to an app you already have, or build a new kind of app that runs entirely on your users' machines. Either way, layer on capabilities like Sign It as you grow.
