Vessel Browser – An open-source browser built for AI agents, not humans
I'm Tyler - the solo operator of Quanta Intellect based in Portland, Oregon. I recently participated in Nous Research's Hermes Agent Hackathon, which is where this project was born. I've used agents extensively in my workflows for the better part of the last year - the biggest pain point was always the browser. Every tool out there assumes a human operator with automation bolted on. I wanted to flip that - make the agent the primary driver and give the human a supervisory role. Enter: Vessel Browser - an Electron-based browser with 40+ MCP-native tools, persistent sessions that survive…
Vessel Browser – An open-source browser built for AI agents, not humans launched on March 21, 2026 with 6 votes, #1,631 of 23,380 launches that month and more than 75% of that year's launches.
What it does
Most browser automation is either headless or bolted onto browsers designed for humans. Vessel flips that model: designed and optimized for agents with human visibility. Built for harnesses like Hermes Agent, Claude Code, BYOK API, and any MCP compatible client, Vessel gives autonomous agents a full Chromium browser with: 80+ MCP-native tools, persistent named sessions that survive restarts, supervisor sidebar with live approval, and agent optimized pipelines.
Vessel is a browser built for AI assistants. It lets agents open websites, click buttons, fill forms, remember sessions, and show their work in a real browser you can supervise.
Vessel lets an AI assistant open websites, click buttons, fill forms, remember sessions, and show every step in a real browser you can supervise. Free open-source core. Premium adds saved sessions, vision, page-change history, credential vaults, and longer agent workflows. One prompt. Vessel searches Powell’s, chooses books, and adds them to a cart in a visible browser — so you can see exactly what the agent is doing. Normal browsers are made for people clicking one step at a time. Vessel gives AI assistants a browser workspace where they can read, click, remember, and ask for your help when it matters. Ask an AI to browse real pages, collect useful information, compare options,…from quantaintellect.com

Browserfly2025 · browserfly.app · ▲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…
Nous – Open-Source Agent Framework with Autonomous, SWE Agents, WebUI2024 · github.com · ▲155Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…
Notte Browser Agents2025 · notte.cc · ▲275Hey 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…
ClarkJul 2026 · clarkchat.com · ▲264Hey folks, I've been building Clark solo, with the aim to match Manus agent (I really like it!) in features and capabilities, but also in its relentless ability to just complete tasks while using browser, computer etc. So far I think I've achieved 1:1 core feature parity: 1) computer use agent 2) browser use in same thread 3) wide and deep research - clark calls clark 4) integration with google tools Would love to have community feedback and for you to try it out, a couple thousand people already using it daily for very broad use cases. You can use this referral link, that hopefully works…
