H33-BotShield
Replace reCAPTCHA with cryptographic proof of work
What it does
Frictionless session token cryptography run out of browsers that removes all bots as people use it (because the math gets harder over time) All we do is move the math cost to the bots from you the user. There are no walls...just math models bots won't touch. https://h33.ai/demo/fraud-prevention/ unalias npm npm install @h33/botshield

- SAStop AI scrapers from hammering your self-hosted blog (using porn)Dec 2025 · github.com · ▲373
Alright so if you run a self-hosted blog, you've probably noticed AI companies scraping it for training data. And not just a little (RIP to your server bill). There isn't much you can do about it without cloudflare. These companies ignore robots.txt, and you're competing with teams with more resources than you. It's you vs the MJs of programming, you're not going to win. But there is a solution. Now I'm not going to say it's a great solution...but a solution is a solution. If your website contains content that will trigger their scraper's safeguards, it will get dropped from their data…
- CHCloakbits - Headless web scraping with bypass for anti-bot WAFs2021 · ▲8
There is a growing number of companies offering anti-bot protection SaaS to protect websites from scraping by automated bots based on Puppeteer/Selenium. Most of them rely on browser properties such as headers, javascript properties (window., navigator.), behavior analysis, to build device/user fingerprints and match it against a database of "whitelisted" fingerprints (typical user behavior/settings/device props etc). For the past few months, together with two other devs I have worked on a customized Puppeteer/Playwright scraping backend. It's essentially a drop-in…
- RCReplace CAPTCHAs with WebAuthn passkeys for bot prevention2024 · github.com · ▲71
I built Nocaptcha after getting frustrated with traditional CAPTCHAs both as a user and developer. WebAuthn passkeys offered a promising alternative that's both more secure and user-friendly. What makes Nocaptcha different: - Uses WebAuthn standard instead of puzzle-solving - No need for users to remember passwords or solve puzzles - Open source Current limitation: Working with W3C WebAuthn Community Group on true passkey disposal for this use case. Looking for feedback particularly on: 1. Integration experience 2. User experience compared to traditional CAPTCHAs
- TTTalk to AI Models in Terminal2023 · github.com · ▲9
Hi everyone, nice to meet you and I am a newcomer of HN. I have made a binary tool Aih that could communicate with Bard, ChatGPT, Claude, and Llama(HuggingChat) from the terminal. https://github.com/Databingo/aih Since CAPTCHA challenges and bots detecting have become increasingly difficult, I've changed my strategy from hacking the APIs to simulating a real browser's action. The tool first takes the logged-in cookies of Google, ChatGPT, Claude, and HuggingChat accounts from the real Chrome browser, then it opens an invisible instance of Chromium for communication, then…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…
