Prynt vs FingerprintJS
Prynt is the FingerprintJS alternative with a free tier — the same visitor IDs and Smart Signals, at flat, predictable pricing instead of a per-call meter.
FingerprintJS Pro is a strong, mature product — this page is an honest look at where Prynt differs. The short version: if you want the same visitor IDs and Smart Signals with a free tier and flat, predictable pricing instead of a per-call meter, Prynt is built for you. If you need a decade-old brand with SOC 2 in hand today, FingerprintJS is a safe choice.

Why teams switch to Prynt
- Start free: a genuine free tier with visitor ID and bot detection — no credit card, no trial clock — so you can validate before you pay a cent.
- Predictable cost: flat monthly plans, not per-identification metering. Identify every request without watching a meter climb.
- More signals, no upsell: behavioral biometrics, residential-proxy and AI-agent detection are in Pro, not a bespoke enterprise add-on.
- Built for LatAm too: Spanish and Portuguese docs and console, and a drop-in migration path from the FingerprintJS browser API.
Migrating is a small diff
Prynt’s browser agent mirrors the familiar load() / get() shape, so
migration is mostly swapping the script URL and endpoint. See the
migration guide for a side-by-side.
