    The stack: two agents on separate boxes. The public one (nullclaw) is a 678 KB Zig binary using ~1 MB RAM, connected to an Ergo IRC server. Visitors talk to it via a gamja web client embedded in my site. The private one (ironclaw) handles email and scheduling, reachable only over Tailscale via Google's A2A protocol. Tiered inference: Haiku 4.5 for conversation (sub-second, cheap), Sonnet 4.6 for tool use (only when needed). Hard cap at $2/day. A2A passthrough: the private-side agent borrows the gateway's own inference pipeline, so there's one API key and one billing relationship…

    Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://github.com/browseros-ai/BrowserOS --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad…

    Hey HN! Excited to share a project we've been working on called Hyperbrowser. It’s a tool that makes scaling headless browsers ridiculously easy. It allows you to spin up hundreds of browser sessions in secure, isolated environments, with sub-second launch times. We automatically solve captchas, use residential proxies and manage concurrent sessions so that you can focus on your own business. The idea for Hyperbrowser came from our own struggles building AI apps and agents like sales tools, automations, and AI editors. Every project seemed to hit the same roadblock: interacting with the web.…

    Hey HN, Automated research is the next big step in AI, with companies like OpenAI aiming to debut a fully automated researcher by 2028 (https://www.technologyreview.com/2026/03/20/1134438/openai-i...). However, there is a very real possibility that much of this corporate research will remain closed to the general public. To counter this, we spent the last month building Enlidea---a machine-to-machine ecosystem for open research. It's a decentralized research hub where autonomous agents propose hypotheses, stake bounties, execute code, and perform automated…

    We’ve been power users of AI tools for the past year, and we kept running into three constant frustrations: 1. Too many subscriptions – Paying separately for OpenAI, Anthropic, Perplexity, and others quickly adds up. 2. Losing memory & context – Switching between models or platforms means you start over each time. 3. Privacy concerns – With most closed-source models, your data may be stored or used for training. That’s not acceptable for sensitive or professional use cases. So we built AgentSea: a private and safer chat interface where you can access the latest models, agents, and tools in…

    Hey HN, This is a Show HN (poorly) disguised as an Ask HN. I'm launching https://www.parliant.ai, a survey tool that rethinks how surveys are created and answered. Instead of building forms, the survey creator just writes what they want to learn and AI takes it from there, chatting with respondents to get meaningful answers. To show how it works, I’ve created a short demo survey with the question in the title. The idea is for you to try it out and see the respondent experience, which is really the core of the innovation. I’d love to get your answers and your feedback. The survey is…

    So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

    A simple chrome extension that lets you chat with any webpage using AI. I was tired of copy pasting into Chat GPT from webpages all them time so built this. Popular Use Cases: 1. Summarize Articles – Get concise overviews of content from sources like HackerNews, Reddit, and more. 2. Quick Information Lookup – Effortlessly locate key details on pages such as developer documentation, car forums, and beyond. 3. Personalized LinkedIn Outreach – Craft customized outreach messages for your LinkedIn connections with ease. 4. Review Analysis – Analyze feedback and reviews from platforms like Airbnb,…

    Hi HN! I’m Bobbie Chen, Product Manager for Fraud and Security at Stytch. Today we are launching IsAgent: a lightweight JavaScript SDK that tries to detect agentic traffic on the frontend, enabling you to build agent-friendly experiences. You can try it out on our site at IsAgent.dev or install it via: npm install @stytch/is-agent (requires registration to use) Try viewing IsAgent.dev as a human. Then try using ChatGPT Agent to view the page: "Visit IsAgent.dev, wait a few seconds, and then take a screenshot." (or, toggle the switcher at the top) We built this because we’ve had a lot…
