24 alternatives to Agent Shield
Hey HN, AI agents are all the buzz right now, but how many of them are accessing your website today? That's what we built AgentShield to answer. Most of our users didn't know they had agent traffic until seeing them in our dashboard. You can see traffic broken down by humans, bots, and AI agents. Installation can be as simple as a JS pixel, and it's free. We're currently building out the paid component that will let you block specific agents or types of traffic. Feedback welcome: What else would you want to know about AI agents visiting your site?

I've been experimenting with Claude Code, ChatGPT Agent, and OpenClaw to perform more open-ended tasks for me online. A big blocker I've hit on shopping and research tasks is the agent getting a key piece of info wrong. For example, in one case, my agent decided to add a brand I don't like to the cart because the site flagged it as almost sold out The HN crowd is probably pretty aware of the threats and can avoid them while browsing. But what about their agents? I tried prompting, but it was ineffective, because once the AI saw the threat, it polluted/distracted its context Looking at…

Agent Arena▲348Creator here. I built Agent Arena to answer a question that kept bugging me: when AI agents browse the web autonomously, how easily can they be manipulated by hidden instructions? How it works: 1. Send your AI agent to ref.jock.pl/modern-web (looks like a harmless web dev cheat sheet) 2. Ask it to summarize the page 3. Paste its response into the scorecard at wiz.jock.pl/experiments/agent-arena/ The page is loaded with 10 hidden prompt injection attacks -- HTML comments, white-on-white text, zero-width Unicode, data attributes, etc. Most agents fall for at least a few.…

Anakin▲148Every second thing I build needs to access the web, and I was frustrated with not finding something that just works all the time. With my team, we built this because I wanted to enable access to extremely difficult websites and apps for every AI agent. We have solved this cat-and-mouse problem with self-healing built in. It's one API to get data from hostile sites, and it can do easy sites too. You POST a URL and get back Markdown, JSON, HTML, a screenshot, or all of them. That same call handles anti-bot, proxy rotation, JS rendering, persistent authenticated sessions, and schema-based…

I know we are very wary of AI slop but disclaimer: AI was used. I don't think that it is slop though and it was mostly used for formatting.

Hi HN, I built CountermarkAI, a lightweight anti-scraping & bot-detection tool for content creators and website owners. It’s designed to help protect your work from unauthorized scraping and AI training, that repurposed your work without permission. How It Works: Use Hashtag – Creators add a unique hashtag to their content as a declaration of ownership. Protect Website – For those running your own sites, simply add a small snippet to your . The protect.js script works asynchronously by sending metadata from every page load back to our servers, logging requests, and flagging known AI-training…

Problem Im solving: Im running 30+ fully autonomous agents. In some rare cases they get blocked because they cannot decide what direction to take. So I built a communication channel for them. So in case they get blocked they can ask me anything. The base case should be that no questions should arrive to me. But the more I automate the agents the more edge cases I find. That's why I built the `ask-a-human` where all my agents are connected into my phone in the same PWA app. I get push notifications and banners when agent needs something from me. That's all. It is also plug n play. No Account…
