FingerPrint Checker vs fingerprint.com
fingerprint.com is a mature visitor-identification service that gives you an identifier and a large catalogue of signals to build rules on. FingerPrint Checker gives you the decision itself for trials, coupons, quotas and referrals. They suit different jobs, and some teams could use both.
| Topic | FingerPrint Checker | fingerprint.com |
|---|---|---|
| What you get back | A decision: allow, human check or deny, with a reason, plus quota, household and claim-group logic. | A visitor identifier and Smart Signals; you write the rules that decide. |
| Signals shown to you | Every event carries signals you read with your secret key: network, VPN, proxy, bot, tampering, virtual machine, velocity and, for apps, emulator, root or jailbreak, hooking, traffic interception, device VPN, location spoofing, cloned app and attestation. The decision call returns the decision and reason; rule names and scores stay on the server by default. | A large catalogue of Smart Signals, such as bot, incognito, VPN, tamper, virtual machine and suspect score (browser), and emulator, root, jailbreak, Frida and cloned app (mobile). |
| VPN and proxy | Yes: separate VPN, proxy, datacenter, Tor and iCloud Private Relay fields on each event, with the reasons for VPN. | Yes: VPN and proxy signals; Tor via the IP blocklist. |
| Bot and tampering | Yes: bot (good, bad or not detected, with the kind seen), tampering and anti-detect browser, plus privacy browsers named when known. | Yes: bot detection, tamper detection and related browser signals. |
| Bot classification | Yes: each event says good bot, bad bot or not detected. A good bot is one we can confirm; a named bot we cannot confirm, or one that imitates a bot we can, counts as bad. | Yes: good and bad bot classification. |
| AI agent detection | Yes: AI crawlers, AI search, AI assistants and AI agents in our directory are recognised by name, agents that sign their requests can be confirmed, and impersonators are flagged. AI browsers that look like an ordinary Chrome are not detected. | Yes: AI agent detection. |
| Bot directory | Yes: a public directory of 142 named bots with operator, category and label, and rules that allow or deny a bot by name or category. | Yes: a public bot directory. |
| Bot check without the browser script | Yes: your backend can send the details of a plain HTTP request and get the bot result and network facts back, with no script in the page. It is not billed and writes no event. | Yes, in preview: a bot API that works without the browser script. |
| Virtual machine | Yes, for browsers. | Yes, for browsers. |
| Velocity | Yes: distinct IPs, countries and linked IDs, and event counts, over 5 minutes, 1 hour and 24 hours. | Yes: velocity signals. |
| IP blocklist | Yes: IPs known to belong to malicious infrastructure; unknown, not clean, when the check is unavailable. | Yes: IP blocklist signal. |
| Incognito detection | Yes, in Chrome and Firefox on desktop. Other browsers and apps return null. | Yes, for browsers. |
| Developer tools detection | Not available. The field is always null. | Yes, for browsers and mobile. |
| Pricing model | Prepaid packs, one credit per decision, 2,000 free on sign-up. 10,000 for $19, 60,000 for $99, 300,000 for $399. Identify is free. | Free plan up to 1,000 API calls a month with a 14-day Pro Plus trial; Pro Plus $99 a month for 20K API calls, then $4 per 1,000; Enterprise by quote. Billed on API requests. |
| Regions | One region, no choice. | Global (US), EU and Asia API regions. |
| Platforms | Web agent; Android, iOS and macOS SDKs (open source); Flutter and React Native wrappers; CLI and MCP server; server SDKs for Node.js, Python, Go, Java, PHP and .NET. | Web, Android and iOS SDKs, plus server API and webhooks; more frameworks and server libraries are listed in their docs. |
| Team members and roles | Yes: invite teammates to an account with owner, admin, billing, editor or viewer roles. | See their documentation. |
| Audit log | Yes: every change to projects, keys, webhooks, rules and members is recorded with who made it, and you can read it in the console or through the Management API. | See their documentation. |
| Environments | Yes: add environments such as staging under a project, each with its own keys, events and webhooks, and copy settings between them. | See their documentation. |
| Management API | Yes: account-level management keys (mk_…) with read and write scopes manage projects, environments, key rotation, webhooks and rules, and read usage, audit, events and visitors. | See their documentation. |
| MCP server and CLI | Yes: the fpchecker command line and a local MCP server for Claude Desktop, Cursor and Claude Code. The server is read-only unless you turn writes on. | See their documentation. |
| Cross-browser and household | Browsers on one computer and network resolve to one visitor; household limits; claim groups across your site and apps; later flags for related claims. | Visitor identifiers per browser or device. Check their docs for related-visitor features. |
| Mobile platform proofs | Play Integrity, App Attest and DeviceCheck verified on the server. | Mobile signals such as emulator, root, jailbreak, Frida and tamper detection. |
| Mobile device signals | Root or jailbreak, hooking frameworks, emulator, debugger, developer mode (Android), traffic interception, device VPN, location spoofing and cloned app (Android), each true, false or unknown. Recorded and returned to you, but not scored yet: they do not change the trust score or the decision, and act only through rules you write. Factory reset detection is not available. | Emulator, root, jailbreak, Frida, cloned app, factory reset, location spoofing, MitM, VPN and app tampering. |
| Human check | Built-in proof-of-work or your own Turnstile widget. | Bot detection and other signals; you decide what to do with them. |
| Events API and webhooks | Every identify is an event you can read and search with your secret key, tag with your own ids, and receive as a signed webhook. Browsers and apps only see the event id. | Server API and webhooks. |
| Open source | Client SDKs and protocol (Apache-2.0); server hosted. | Hosted commercial service; its open-source library is a separate product (see our guide on client-side libraries). |
The difference in one paragraph
With fingerprint.com your backend receives an identifier and many signals and decides. With FingerPrint Checker your backend receives allow, a human check or deny, and the rule names stay on the server so a response cannot teach an attacker what to change. If you want to design your own rules from rich signals, fingerprint.com gives you more to work with. If you want one-claim-per-person enforced without writing the rules, that is what we do.
Where fingerprint.com is stronger
- A much larger catalogue of signals, including factory reset detection and other mobile-only signals, and the developer-tools signal, which we do not offer. Our incognito signal covers Chrome and Firefox on desktop only.
- Three API regions (Global, EU and Asia); we run one.
- More platforms and frameworks, and server libraries listed in their docs.
- A longer track record in this market.
Where FingerPrint Checker is stronger
- A decision API that returns allow, a human check or deny with a reason.
- Household logic: several browsers on one computer, devices on one home network, claim groups across your site and apps, and later flags for related claims.
- Platform attestation checked on our server: Play Integrity, App Attest and DeviceCheck.
- A built-in proof-of-work human check, or your own Turnstile widget.
- Single-use, purpose-bound attestations, so a captured request cannot be replayed.
- Prepaid credits, and free identification.
Pricing is not directly comparable
fingerprint.com bills API requests; we bill decisions. The units differ, so compare against your own traffic rather than the headline price. We do not publish a fraud-prevented figure, and neither side’s price tells you the cost of your abuse.

Frequently asked questions
Can I switch from fingerprint.com?
The integration is different: instead of reading signals and writing rules, your backend asks for a decision. Many teams start by running both on one flow and comparing the outcomes.
Is this comparison complete?
No. It covers the points we can verify from public pages. If something here is out of date or wrong, tell us through the contact form and we will correct it.
