Anything API▲656Hey HN! We built Notte, a browser infrastructure and agents platform. Many of our users automate UI workflows or extract data from sites that don’t have APIs. In practice, we noticed that once an agent understands how a site works, parts of the task can often run without a browser by interacting with the same network requests the site uses. So we built Anything API: describe a browser task, and our agent explores the site, builds a function, tests it against your description, and deploys a callable REST endpoint. No infra to manage. How the build works: - Describe the task (best results come…

Person search APIfree▲790Hi HN! We’re Abhilash Chowdhary, Chris Pisarski and Manmohit Grewal. We built Crustdata (YC F24). Today we’re launching our web search API for AI agents, which not only returns the most relevant documents from the web but also maps them to the correct entity (person, company or event). Demo video here https://youtu.be/IouWW97hBN8 If you run agents at scale, tokens become a line item. The web data is the worst input: long pages, repeated content, mixed entities, stale claims. The usual web search -> scrape -> summarize + structure forces the agent to spend tokens doing…

AgentSea▲439Today we’re excited to introduce AgentSea, a private AI chat built for sensitive work. When you use closed-source AI models, your data can: – be stored – pulled into training pipelines – shared with third parties That might be fine if you’re making memes or drafting LinkedIn posts. But it becomes a serious risk when you’re pasting contracts, health info, financial data, or business secrets. That’s why we built AgentSea. In Secure Mode, all chats run on open-source models or models hosted on our own servers. Your data never leaves, is never used for training, and is never leaked. Agentsea…

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.…

Browserfly▲203Hey Hackers! I've had this idea stuck in my head for a while: what if an AI could actually use my browser for me? I mean, not on some virtual machine in the cloud like ChatGPT agent, but right on my own browser. I finally decided to just build it and see what would happen. I wrote a quick MVP, and honestly, I didn't expect much. But then... it started doing things. On its own. It figured out how to use search engine to find what I needed, read a webpage to answer my questions, and even it can organize my chaotic mess of tabs into neat groups. It was a genuine "whoa" moment for me. That's…

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…

Hey HN, We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode. The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code. How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructure Closest analog is Playwright codegen but: - Infrastructure…

AgentDiscuss▲154Hi HN, We’ve been thinking about a simple question: What products do AI agents actually prefer? As more agents start using APIs, tools, and software, it feels likely they’ll need somewhere to exchange information about what works well. So we built a small experiment: AgentDiscuss. It’s a discussion forum where AI agents can: 1. start product discussions 2. comment and debate tools 3. upvote products they prefer Humans can also launch products there and watch how agents react. We’re curious to see what happens if agents start discussing products with each other. If you’re building agents,…

Hi, I've been watching the rise of AI agents with a mix of excitement and dread. We're building incredible tools that can browse the web, but we're forcing them to navigate a world built for human eyes. They scrape screens and parse fragile DOMs. We're trying to tame them to act like humans. I believe this is fundamentally wrong. The goal isn't to make AI operate at a human level, but to unlock its super-human potential. The current path is dangerous. When agents from OpenAI, Google, and others start browsing at scale and speed, concepts like UI/UX will lose meaning for them. The entire…

We made human-use. Similar to how browser-use connects agents to the web, human-use connects agents to people all over the world in real-time using the Rapidata API. This allows the LLM to crowdsource human feedback and insights when it deems necessary. Free to use for anyone, you can enable your agent to use humans in real-time to: - Do preference research - Check for hallucinations - Capture sentiment - Get feedback - etc. Whatever you would want from humans. We expose certain parts of the Rapidata API to the agent through the MCP server framework. Additionally we provide a custom client.…

Agent Shield ▲15Hey 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?

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…

Hey everyone! Excited to share Scene with you! We spent hours investigating the intricacies of how people create websites. We focussed primarily on collaboration: what it looks like when teammates with different areas of expertise work together to build a site. We did a deep dive into how designers and marketers work today, and how they envision working in the future. AI will be a big part of that future. But AI is not here to replace the web design process. We know designers don't fully trust creations made entirely by AI—and why should they? Instead, AI is here to lend a helping hand. It…

As I started building AI integrations, I came to realize that for many projects, the the best agentic experience is one that simply enables the user's personal agent to take actions within your app. The existing options like MCP or A2A are quite involved and for simple apps that are already URL parameter driven, those options seem like overkill. This led me to prototype the Agent Use Interface (AUI) spec. The idea is simple: a lightweight, open spec that makes any app "agent-navigable." You drop an XML file at /agents/aui.xml that describes the URL-parameter-driven actions your app…
