The browser where agents act and humans supervise
Most browser automations are either headless or bolted onto browsers designed for humans. Vessel flips this model: built and optimized for agents while remaining visible to humans. Compatible with tools like Hermes Agent, Claude Code, BYOK API, or any MCP client, Vessel provides agents with a full Chromium browser featuring over 40 native MCP tools, persistent sessions, a real-time supervision sidebar with interactive approval, and agent-optimized pipelines.
For university students, Vessel enables autonomous web research and organized note-taking. For example, an agent can be tasked to find five academic papers on a specific topic, extract key findings, and save them to a designated folder, streamlining the research process.
For solopreneurs, Vessel allows for the automation of repetitive online business tasks. For instance, an agent can be configured to monitor competitor pricing across multiple e-commerce sites and compile a daily report, freeing up valuable time for core business activities.
For academic researchers, Vessel facilitates the systematic collection of data from diverse online sources. An agent can be set up to visit specific academic journals, extract citation data for a particular study, and store it in a structured format for analysis.
For content creators, Vessel helps in discovering and organizing inspiration from the web. An agent can be instructed to browse design blogs, identify trending visual styles, and save examples with annotations, providing a rich source for future content creation.
For web developers, Vessel provides a controlled environment for testing web applications using AI agents. An agent can be tasked to perform a full user journey on a new feature, such as signing up, making a purchase, and verifying order confirmation, reporting any discrepancies.
Vessel is open-source and free to use, with core features like navigation, page reading, and basic interaction available without cost. A premium version offers advanced capabilities for power users and production workflows.
The core Vessel browser is free and open-source. Vessel Premium, which unlocks advanced features like screenshot analysis and session management, costs $9.99 per month with a 5-day free trial.
Vessel is currently available as a desktop application for Linux. There is no mention of mobile or web versions in the provided information.
You can install Vessel via npm with `npm install -g @quanta-intellect/vessel-browser`, by downloading an AppImage for Linux, or by cloning and building from the source code.
Alternatives to Vessel would depend on specific needs, but general browser automation tools like Selenium or Playwright offer programmatic control. For agent-specific browser interaction with human oversight, Vessel appears to be a unique offering.
Vessel is described as being in active development and currently makes no security assurances. Information regarding GDPR compliance is not readily available.
Vessel is designed specifically for AI agents, offering persistent sessions and human supervision, differentiating it from general automation tools like Playwright or Selenium which are primarily human-centric. The choice depends on whether you need an agent-first browser or a general automation framework.
