In their own words
BrowserOS
BrowserOS is an open-source Chromium-based browser with AI agents for carrying out web tasks from natural-language directions. The agents can navigate, click, type, fill forms, extract data, and run workflows across multiple steps. Chat Mode answers questions about the page in view; visual Graph Mode for repeatable workflows is marked as coming soon. BrowserOS supports Gemini, Claude, OpenAI, and local models through Ollama or LM Studio. Its maker lists more than 40 MCP app integrations, including Gmail, Slack, Notion, and Calendar, as well as 53 built-in browser tools. An included MCP server connects with Claude Code, Gemini CLI, or Codex. As a Chromium fork, it supports Chrome extensions and import of Chrome bookmarks, passwords, and settings. Browsing data stays on-device unless cloud syncing is enabled; syncing is off by default, and synced activity is encrypted on BrowserOS servers. BrowserOS says it does not store or log AI prompts or responses, though providers may handle submitted data under their own policies. It is free and licensed under AGPL-3.0.

ChatGPT and Gemini are available from the sidebar, and Opera says its AI tools do not require sign-up. The sidebar also offers WhatsApp, Slack, Discord, Messenger, and Telegram, while Music Player supports Apple Music, Spotify, YouTube Music, and Deezer. Users can set browsing data—including history, cookies, passwords, and autofill data—to clear on exit. Opera browser costs nothing. VPN Pro is separate: plans cost $4 per month billed $48 yearly, $5 per month billed $30 every six months, or $8 per month billed monthly.
