Device intelligence you actually own
Prynt is MIT-licensed and self-hostable. Run the entire stack yourself, keep every byte of visitor data, and skip per-API pricing forever.
MIT-licensed
Permissive licensing across the whole stack — use it, fork it, ship it, no strings.
Self-host in minutes
One docker compose up brings up the API, admin console, browser CDN and datasets.
Own your data
Raw visitor data stays on your infrastructure — nothing is phoned home to a vendor.
No per-call pricing
Fingerprint every request. Your only cost is the infrastructure you already run.
Batteries included
Seven server SDKs, four mobile SDKs, and Cloudflare/nginx edge connectors ship with it.
Open protocol
A documented identify + verify contract means no lock-in and a clean migration path.
Why open source wins for fraud tooling
Closed fraud vendors ask you to send them your users' most sensitive signals and trust a black box. Open source inverts that: you can read exactly how every signal is computed, run it on your own infrastructure, and prove to auditors that nothing leaves your environment. Transparency also means the detection logic improves in the open.
The whole stack, in one repo
The monorepo contains the browser agent, the Flask API and matching engine, the admin console,
SDKs for seven server languages and four mobile platforms, and the
edge connectors. Bring it all up with a single
docker compose up.
