24 alternatives to Fingerprinting browser-impersonating bots w/o JavaScript (open spec)
I've published an open specification for a detection method I'm calling RQ4 (Request Context Fingerprinting). It analyzes whether HTTP request headers are logically consistent with real browser behavior - not just what headers are present, but whether they make sense together given the request context.
Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Owl Browser▲145I've been working on browser automation infrastructure for a while and kept hitting the same ceiling: Playwright and Puppeteer are great for scripting but fall apart when you need stealth at scale. Cloud-based solutions like Browserbase work but you're sending all your data to a third party and can't control the environment. So we built Owl Browser, a self-hosted Chromium-based engine that runs in a single Docker container. The core technical problem we tried to solve was fingerprint consistency. Most browser automation tools either ignore fingerprinting entirely or apply surface-level…

BoringSSL and nghttp2. Matches JA3N, JA4, and JA4_R fingerprints. Supports HTTP/2, async/await, and works with Cloudflare-protected sites. Not trying to compete with curl_cffi - just a learning project that turned into something functional.

This is a small PoC Python project for web server access logs analyzing to classify and dynamically block bad bots, such as L7 (application-level) DDoS bots, web scrappers and so on. We'll be happy to gather initial feedback on usability and features, especialy from people having good or bad experience wit bots. *Requirements* The analyzer relies on 3 Tempesta FW specific features which you still can get with other HTTP servers or accelerators: 1. JA5 client fingerprinting (https://tempesta-tech.com/knowledge-base/Traffic-Filtering-b...). This is a HTTP and TLS layers…

Not new but quite cool. Note: https://creepjs.org/ is NOT official the repo is https://github.com/abrahamjuliot/creepjs Anyone knows how fingerprinting works mathematically? what do they use? when the signals may vary even slightly, your final hash should be sufficiently accurate and stable. A simple hash won't do it. Changing IP, missing cookies/session, resizing window, TLS/SSL browser handshake, screen depth, font rendering, MTR, network latency if you want to measure, etc... any signal alone means little but as a whole mathematically what is…

IPDetective collects data from about 60+ different sources such as official cloud provider endpoints and public VPN/Proxy/Tor/Bot net lists. Then aggregates this data into a fast and easy to use API that can be integrated into applications or scripts easily. IPDetective started as a hobby project for my other hobby projects :) and I decided to wrap a simple website around and offer it as a service. Let me know what your thoughts, if you find value in this service or if you have any feature requests.

I made FingerprinterJS, a small library with no dependencies that creates browser fingerprints from signals like canvas, WebGL, audio, fonts, userAgent, and screen info. It’s written in TypeScript, lets you enable/disable collectors, add custom data, and includes a simple suspicious-activity score. Would love feedback.

This is a simple single-file python program that can find basic XSS (cross-site scripting) vulnerabilities in a target url. Most XSS discovery tools use a payload refelection strategy in which payloads are injected in url parameters and the GET response is inspected for places where the payload content is reflected. This is a very low precision XSS detection strategy because most reflection does not support execution. This program uses a different approach, and instead opens the target url in a browser, tests alert(...) payloads directly in the browser context, and listens for an alert being…
