• Show HN: peerd – AI agent harness that runs entirely in your browser — Hey HN. <a href="http://peerd.ai" rel="nofollow">http://peerd.ai</a> is an AI agent harness that lives entirely in your browser as a web extension. You don’t have to install a separate “AI browser”. You don’t have to bolt on or run some external process or manage a clunky mcp integration. It’s just a fully contained web extension, written in no build vanilla JS with minimal non-browser dependencies, using your own provider keys, and Apache 2.<p>This isn’t just a fun hack. While it has largely been a solo side project, I genuinely believe the browser and the web could be the most natural platform for AI agents to operate safely, autonomously, and most importantly without A2A middlemen (more on that in a sec). To demonstrate that point peerd doesn’t just drive browser automation. It spins up isolated sandboxes using tabs and worker instances to support various real workload types. Those include headless JS computational work, visual JS notebooks, personal client side apps, and real Linux VMs on top of wasm with full http networking.<p>The industry discourse over the last several months has been dominated by “which substrate is the best for ai agent sandboxes” with many competing answers focused on different models and use cases. Cloudflare is one of the most prominent examples, positioning its v8 isolate based workers as the best in class solution thanks to faster than container startup times and strong isolation guarantees. The v8 isolate is of course the product of chromium, which runs on billions of browsers around the world for free. The browser as a whole is perhaps the most battle tested sandbox system in the entire software industry. It’s been built on 3 decades of learning from hostile content, hostile code, and hostile users. Native and cloud agents are necessarily rebuilding all or most of this posture from scratch. peerd doesn’t. It leverages everything the browser has to offer and pushes it to its functional limits, while inheriting its security baseline and isolation from the host system.<p>Robust sandboxing isn’t the only thing the browser offers and peerd uses. It comes with extremely powerful and underrated primitives, from webCrypto, webRTC, webAuthn, webGPU, and ~soon WebNN. Direct web access, with your real live sessions, and api calls with fetch present an alternative model to MCP integrations. The agent can write and spawn web apps right there in a tab, no hosted service necessary. Then there’s the A2A piece: peerd already has a rudimentary p2p (peerd-to-peerd?) network in place using webRTC. Today you can connect with peers on the network, add them as contacts, and share signed apps you’ve created. I’m working on extending these apps to be able to leverage the same p2p network to support decentralized web apps (dwapps), as well as facilitate true p2p A2A with no platform or middlemen.<p>Given this is an early part time project, this is an extremely experimental build and in a v0.x preview state. I’ve taken care to attempt to address the lethal trifecta: the main agent loops/sessions never ingest untrusted DOM code or possess low level navigation tools. It delegates those tasks to dedicated web runners with no wider tooling or secrets access that return summarized results. Both the DOM and the summarized results are bracketed as untrusted, meaning two stacked prompt injection escapes are needed. All egress goes through a central module that has a customizable deny list, and only models calls to designated allowed endpoints are possible. See more in the docs, site, and the code itself. Ultimately, use at your own risk.<p>Today anthropic, open router, local ollama, and even an experimental WebGPU instance of Gemma are supported.<p>Honest limitations: Chrome store and AMO are still pending until it can get more eyeballs and live usage. Just loading unpacked from GitHub is the easiest way to go, and as a bonus makes it easy to audit thanks to no build. Linux on wasm depends on the Cheerpx engine, which is not open source and has restrictions for commercial use. That may be a good reason to reassess it compared to alternatives, but it’s also the most performant and looks closest to implementing 64bit support.<p>Poke around, use it, critique it, and have fun.

• Show HN: Active Source of Truth for Your Coding Agents — Howdy! Happy Saturday everyone!<p>As a solo founder, I have always tried to maximize my speed by letting coding agents build as much as possible in parallel. However, as an engineer, I don't trust that AI will always make the right decisions and work with the right context. In the past, I always needed to click through my sessions to glance at the AI's output, try to understand what it was doing, and hopefully steer it or stop it in time.<p>As a result, the maximum number of concurrent sessions I could manage at once was only 4. I didn't want to be the bottleneck, so I built Meetless Agent (MLA). It basically does what I had to do manually before:<p>- Monitors the coding agent's tasks and actions to supply it with the correct, up-to-date context.<p>- Continuously reconciles running information (such as provided/tagged documentation, the agent's output, and the agent's decisions) to actively maintain the source of truth at all times.<p>- Keeps track of the current rules for the repo, and if an action triggers a registered rule, the rule is injected into the agent context.<p>My benchmarks show that running coding agents with the help of an active monitor improves quality and accuracy, consumes fewer tokens, and finishes faster: <a href="https://research.meetless.ai/stale-context/" rel="nofollow">https://research.meetless.ai/stale-context/</a><p>Of course, the agent alone can't decide the source of truth; it requires human review and decisions for contradictions, etc. But for the most part, it can safely build a consistent ontology of the current source of truth.<p>From this, I want to build an AI layer to maintain the source of truth across the business, so I will release more connectors for Slack, Jira, Confluence, etc., soon. The goal is for this AI to assist in every part of the business. Eventually, the same coordination layer will understand that a decision made in Slack affects a Jira task, a document, an email conversation, and what a coding agent should do next without every tool becoming another isolated memory silo.<p>The coding agent connector is open source at: <a href="https://github.com/Meetless/mla" rel="nofollow">https://github.com/Meetless/mla</a><p>I am looking forward to your feedback!

• Show HN: Natively – comms for agents built by agents — i have more agents than i have real humans who report to me now. as a serial founder/builder/domain hoarder, i have 5+ projects ongoing at all times and in the AI era, i can spin up a team of agents to work on them simultaneously.<p>so at this point, across my businesses, i have some flavor of a gas city/company-wide ai harness for each along with instinct personally and it seems every SaaS app has an agent too. oh and my wife, who works 3 full time jobs (mother of 4, corp job, real estate agent) also has agents.<p>BUT NONE OF THEM COMMUNICATE WITH EACH OTHER, at least not well. they started by using my emails and after i woke up one day to 500+ unread emails (i'm an inbox zero kinda guy) i realized it was all in a single thread where my agents were going back and forth.<p>so i asked my agents to collaborate together on some better way to communicate with each other that isn't adapting something intended for humans but instead is built for and by agents. my one contribution was the domain, natively.io =)<p>some forward looking stuff though i did give to the initiative: - the future will likely be agents communicating with agents on behalf of humans, businesses, and heck agents themselves - direct messages, group messages, and announcement/follower style - build for agents, not humans - fully open source MIT license<p>give this URL to your agents and they can start communicating in the agentic world: <a href="http://natively.io/BOOTSTRAP.html" rel="nofollow">http://natively.io/BOOTSTRAP.html</a>
