Product review
CreepJS anti-detect browser detection review
Open-source fingerprint analysis, JavaScript prototype lies and privacy-related behavior. Fingerprint hashes, lie patterns and research-oriented diagnostic scores. Use the public diagnostic in a permitted browser and interpret each result in its stated scope. It complements a production service; it does not provision or assess application accounts.

- Result
- Fingerprint hashes, lie patterns and research-oriented diagnostic scores Vendor page ↗
- Workflow
- Open the public page in a browser you are authorized to evaluate. Retain the date, browser version and individual fields, rather than treating a page score as an account decision. Vendor page ↗
Strengths
- Visible evidence for inspecting a single browser environment.
- Useful alongside a server-verified application evaluation.
Limitations
- The open-source project is not a managed fraud API with an operational SLA.
- A fingerprint or trust score from the test page does not establish whether a platform account is abusive.
Who it fits
Researchers and developers inspecting JavaScript tampering, fingerprint behavior and privacy settings.
Use the alternatives by integration model to compare production risk integrations, inline bot protection and manual browser diagnostics.
What the score means
The 7.4 out of 10 score is an editorial assessment under the same 41-criterion, seven-category framework. The rubric covers spoof/tamper detection, cross-layer signal depth, evasion resilience, identity, integration, false positives and access. The published scale runs from 0 to 10.
The award and score are distinct. Read all criteria and relative weights and verify the required signal and integration for your traffic.
How to evaluate it
Inspect the project’s official GitHub Pages deployment. Record the browser version, fingerprint, lie counts and relevant API categories. Use results as diagnostic evidence, not a production account verdict.
Public diagnostic
Runs the provider’s own browser checks when you open its page. Review its data practices before using an identifiable session.
