The browser where agents drive and humans supervise

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.
Hey Product Hunt!
I'm Tyler, a self-taught AI research engineer in Portland. I built Vessel because I spent the last year using agents as a core part of my research and development workflow - and the browser was always the most appealing, but weakest link.
Every browser automation tool I could find was either not available on Linux, was forked from a human browser with AI features bolted on the side, or didn't provide enough compartmentalization between my data and the data I wanted the agent to have access to. The AI is often presented as first-class, but treated in practice as an afterthought. I wanted to flip that completely: design the browser from the ground-up around the agent as the primary operator, and keep the human in the loop as the supervisor.
Vessel is a browser designed for agents with human-in-the-loop visibility.
It's an Electron-based browser running a Chromium engine with 80+ MCP-native tools, semantic page understanding (agents get structured meaning, not raw HTML), persistent sessions that survive restarts, and a supervisor sidebar where you can see exactly what the agent is doing in real-time whether the agent driving is served over an API, or controlling Vessel through the local MCP server.
I built this solo. No team, and no funding. Just a lot of time dogfooding AI agents and getting frustrated enough to finally build the tool I wish existed. I was laid off from my job as a Systems Engineer in January, which allowed me to start really start grinding.
In the first week, Vessel Browser hit just shy of 1,000 npm installs with zero marketing budget - Just organic discovery and user curiosity. In the first 3 days, Vessel Browser also received 2 feature requests on Github which were fulfilled almost immediately.
Vessel is open source under the MIT license, and I just shipped a premium tier this week for power users who want advanced features like session management, workflow tracking, and extended tool iterations.
I'm truly committed to building the best open source AI browser out there, and I'm deeply passionate about my work. I'd love to hear what you think! I'm here all day answering questions and I'm always around on Twitter.
