Volance vs
Fingerprint
Fingerprint, formerly FingerprintJS, is best known for device identification: a visitor ID that persists for months even after cookies are cleared, with "Smart Signals" layered on top — including bot detection and AI-agent detection. Volance does a different job. It does not identify the device; it scores a session on-site and returns the evidence behind the call.

Approach
Identification vs. scoring
Volance
Volance answers "what is this session, and why". It returns a graded score and the checks that produced it, without building a persistent identifier for the visitor.
Fingerprint
Fingerprint answers "have I seen this device before" — its core is a stable visitor ID across visits, with risk signals attached. That is powerful for account linking and returning-visitor flows, and it is a different product category from session scoring.
Output
What you get back
Volance
A 0–100 human-likeness score, a policy verdict, and named evidence, ready for your own allow, flag, or block policy.
Fingerprint
A visitor ID plus a set of Smart Signals. Its browser bot detection returns good, bad, or not detected and is available on the Pro Plus tier and above.
Classification
Humans, agents, and bots
Volance
Human, agent, and bot are separate classes, and a verified agent can be allowed by policy without being called human.
Fingerprint
Fingerprint also detects AI agents and verifies signed Web Bot Auth requests, distinguishing signed agents from spoofed ones. On this axis, treat it as a close call rather than a clear gap.
Enforcement
Where enforcement happens
Volance
Out of your request path: your backend calls Volance with a secret key and applies your own policy. Nothing of ours can take your site down.
Fingerprint
Also server-side: the browser agent collects an event, and your server calls the Fingerprint API to read the result.
Privacy
Data and privacy
Volance
On-site signals only, no cross-site identifiers, no device fingerprinting unless you explicitly enable it, IP addresses hashed in product records, and 30-day raw retention.
Fingerprint
Persistent identification is the point, and it works without cookies, so the privacy trade-off is different from Volance by design. Fingerprint publishes privacy documentation and controls; review them against your own obligations.
Pricing
Pricing model
Volance
Free to start with 10,000 customer scores a month; Pro is $49/month for 250,000. Only scoring calls are metered, and developer tests are never billed.
Fingerprint
Free for 1,000 API calls a month; Pro Plus starts at $99/month for 20,000 web and iOS calls, with additional requests at $4 per 1,000. Enterprise is custom.
Fit
When Fingerprint is the right call
Volance
Choose Volance when you want to classify a session and explain the decision, without taking on a persistent device identifier or its privacy weight.
Fingerprint
Choose Fingerprint when you need to recognise returning devices across visits — account linking, repeat-abuse detection, or personalising logged-out users — alongside its broader device-intelligence signals.
The verdict
These are more complementary than competing. Fingerprint is device intelligence: identify the device, then decide. Volance is session intelligence: score the behaviour, explain it, and keep the decision on your server. If you need a persistent ID, Fingerprint is the fit; if you want to avoid fingerprinting while still separating humans, agents, and bots with evidence, Volance is the fit.
Frequently asked
Does Volance fingerprint visitors?
Not by default. Volance scores on-site behavioural and client signals. Fingerprint-style signals such as canvas or WebGL checks are a workspace setting that is off unless you turn it on, and turning it on changes what your own privacy policy must disclose.
Is Volance a replacement for device identification?
No. Volance does not claim a persistent visitor ID across visits. It scores a session and returns evidence; if you need to recognise returning devices, that is a different capability.
Can I use both?
Yes. Some teams use device identification for account-level decisions and behavioural scoring for session-level ones. They sit at different layers and can coexist.
