Practical overview

When it fits

Use it when a task requires the AI to operate on websites while you watch, steer, approve important actions, or take over manually.

Who it is for

  • People researching across multiple web pages
  • Users who need help navigating sites or filling forms
  • Developers building browser workflows with MCP or external agents
  • Users who want to connect a selected AI provider through BYOK

Documented uses

  • Research pages and compare information across sources
  • Navigate websites and summarize content
  • Fill forms with review of important actions
  • Continue longer browsing tasks using sessions, checkpoints, notes, and run history
  • Expose browser interaction to compatible MCP clients
Before you choose

Requirements & limits

The project is open source under the MIT license. It documents Linux, Windows, and macOS desktop support; Linux is described as the most mature install target, while macOS release packaging is available from source. Research Desk plan approval, sub-agent execution, and report export require Vessel Premium.

  • Whether you need visible browser activity rather than hidden automation
  • Whether durable sessions, checkpoints, and run supervision matter for longer tasks
  • Whether your preferred AI provider is among the documented integrations or offers an OpenAI-compatible endpoint
  • Whether MCP control or an external agent integration is part of your workflow
  • Whether Linux maturity or source-based macOS packaging fits your setup

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
