# Open-source alternatives to Fingerprint Identification

> We track one open-source alternative to Fingerprint Identification, but it doesn't have confirmed commercial use, local running and no paid services together. The one project we track doesn't cover all 3 Fingerprint Identification jobs, so you may need another tool alongside it.

Fingerprint Identification: Paid, hosted device intelligence API (formerly Fingerprint Pro) from the makers of FingerprintJS. Server-side visitor IDs that stay stable for months, Smart Signals (bot, VPN, tampering, incognito detection), webhooks, a query API and mobile SDKs. Pricing: Free up to 1,000 web API calls/month; Pro Plus $99/month for 20K calls, then $4 per 1,000; Enterprise custom (checked 2026-10-20). Facts checked 2026-10-20.
