Creepjs
Cross-checks every API against the others and reports the lies.
CreepJS is the research tool that looks for tampering rather than for identity. It asks the same question through several APIs, compares the answers, and flags the ones that cannot all be true at once — which is exactly the method an anti-detect browser has to defeat.
What it checks
- Lies: APIs whose answers contradict each other
- Prototype and function tampering in the JavaScript engine
- Engine, OS and hardware claims against measured behaviour
- A trust score with every failed check listed under it
How to read the result
Read the lie list, not the hash. Each entry names the API that was caught and what it should have returned, which is the part you can act on.
What it does not prove
CreepJS is public and old enough that every serious anti-detect build is tested against it. Passing means the build covers the checks it publishes, not that nothing is detectable.
These tools are run by their own operators, not by us. Opening one sends your IP address and browser details to that site.
