Products that do what TunnelMind – reputation API for IPs, ASNs, and ad-tech supply chains does

I'm a network engineer that likes to think about the future of the internet and this is what I've built over many nights and weekends. One reputation graph over IPs, ASNs, domains, and entities, exposed as a JSON API. Try it: curl https://api.tunnelmind.ai/v1/check/1.1.1.1 Every answer is a signed receipt with an attestation tier so you can see what was produced and how your agents can use it. The protocol is opensource. Try it out let me know what you think and yes I am still working on the radar section of the site. Also What would make this useful for you?

    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…

    I tend to use AI to brainstorm domain names, but I kept wasting time pasting each idea into Namecheap to see if they were available. So I built DotComBuddy - it generates ideas (using DeepSeek V3 - switched from GPT-4o after realizing quality was just as good) and checks availability in real time via Name.com’s API. Built with Next.js and Vercel’s AI SDK, the app gives you a table of available domains with their price. 10 free searches to try it out, then $9/year (what I’d pay to never do this manually again). Sharing this for anyone else tired of switching tabs to check domains. Happy…

    Hello, my name is Andrei. My friends and I recently built CentralMind Getaway, an open-source tool that automatically generates AI-agent-optimized APIs from your database connection. It’s designed for those who don’t want to expose direct SQL access to their databases and prefer not to spend time building these APIs manually. What it does: - Auto-generates APIs from your database connection, infer schema & sample data using AI - Filters out PII and sensitive data for compliance (GDPR, SOC 2, etc.) - Optimized for AI-Agent with extra meta information and REST and MCP protocol support -…

    Hey HN, I pay for ChatGPT, Claude, Cursor, and use Gemini through work. Four vendors, four separate conversation histories, four profiles of how I think. None of them talk to each other. Switch providers and you start over. So I built a system where the memory is mine. I run a knowledge graph in Postgres (Supabase, free tier) with pgvector for semantic search. A small MCP server reads and writes to it. That server sits behind an MCP Gateway on a $6/month VPS, along with Brave Search and a GitHub server. TypingMind connects to the gateway as a BYOK client -- any model, any device, same…

    I built TraceAIO, an open-source tool that prompts LLMs on your behalf and tells you whether ChatGPT, Perplexity, and Gemini mention your brand — and which competitors and sources show up instead. Yeah, this category smells a bit like a grift, same as early SEO. And I think over time it will become just SEO again, and become about good content. The tool just helps you monitor over time. It queries the browser products through real browser sessions, not APIs, runs on Docker, with an MCP server so you can query your own data through an LLM. No business model, Apache 2.0, self hosted. If you…

    Hey HN, I'm Ankit, Founder Dottypost (https://twitter.com/ankit_saas) I've been writing content on LinkedIn for almost 2 years. But, the struggle to do consistent posting is real. So I built an AI SaaS that helps with LinkedIn content creation effortlessly. We'd love to get your feedback on the product and anything else that comes to your mind. It would be super useful for us. Thank you!

    Hi HN! After several months of work, I'm excited to share ProKZee, a free and open-source network security tool built with Go and React using Wails framework. ProKZee allows developers, security researchers, and penetration testers to intercept, inspect, and modify HTTP/S traffic — similar to tools like Burp Suite, OWASP ZAP, and Caido — but with a fast native UI, modern UX, and some unique features. https://github.com/al-sultani/prokzee

    hello everyone, my first post! AA here, founder of ⌘ Langbase.com — we are a developer platform for building and scaling serverless AI memory agents. I know surveys can be boring, but this one’s different—it’s interactive! That's very much intentional. My team and I have been up for the last 21 hours putting together this report. This was a looot of work, so I hope y'all like it. Introducing … State of AI Agents 2024 report On Langbase, we processed 184 billion tokens and handled 786 million AI agent runs from 36K developers. From all that data plus insights from 3.4K builders who filled out…

    Hey HN, I built RepoGPT, an open-source AI tool that lets you interact with your GitHub repos using natural language. Ask it things like: How is auth implemented? List API endpoints. What are the key dependencies? RepoGPT aims to make navigating large codebases easier with AI. Check it out: https://github.com/mbarinov/repogpt You'll need Node.js, pnpm, Docker (PostgreSQL), and an OpenAI API key. Full setup in the README. Feedback and contributions are welcome! Also, I'm looking for remote roles in EU time zones. Thanks!

    Hey HN, I’m Chris, a solo dev in Melbourne AU. For the past month I've been spending my after work hours building AgentVisa. I'm both excited (and admittedly nervous) to be sharing it with you all today. I've been spending a lot of time thinking about the future of AI agents and the more I experimented, the more I realized I was building on a fragile foundation. How do we build trust into these systems? How do we know what our agents are doing, and who gave them permission? My long-term vision is to give developers an "Agent Atlas" - a clear map of their agentic workforce, showing where…

    Hello HN, around October last year, I started to work on campaignkit.cc as a side project. It is a service to detect invalid and malicious email addresses. You can upload text files, and use the REST API or direct integration to retrieve a detailed report for each email address. End of March I added Stripe Payments and got my first paying customers via SEM. A coworker suggested starting a Show HN thread, so here we are :) I used golang for the backend since I wanted something lightweight with fast compilation times (coming from scala). For the frontend, I'm using Next.js and TailwindUI. On…

    Hi HN - Last month I attended MicroConf in Denver and met domain investor Andrew Allemann of Domain Name Wire. I know nothing really about that space, but of course the topic of AI came up. He mentioned that he’s tried a lot of domain name generators, and very few provided decent results, and the ones that did (using AI) didn’t show if the domains were available. I thought this problem could be solved pretty easily by combining the ChatGPT API and GoDaddy API into a single, easy to use app. A few weekends later, AI Domain Genius was born: https://www.aidomaingenius.com (And yes,…
