SafeCoBrowser vs Playwright MCP
SafeCoBrowser is an open-source AI co-browsing browser for macOS that lets you bring Claude Code, Codex, or any MCP agent into your logged-in browser — only when you allow it, per tab, with an instant kill switch and a full audit log.
The short version
SafeCoBrowser is an open-source AI co-browsing browser for macOS that lets you bring Claude Code, Codex, or any MCP agent into your logged-in browser — only when you allow it, per tab, with an instant kill switch and a full audit log. Playwright MCP is an MCP server that lets an agent drive a Playwright-controlled browser — generally a fresh, automated context rather than your everyday logged-in profile.
How they differ
- Session: Playwright MCP spins up an automated browser; SafeCoBrowser is your real logged-in browser.
- Permission: SafeCoBrowser is off by default, per-tab, with per-action approval and instant revoke.
- Audit: SafeCoBrowser records a hash-chained log of every action.
- Isolation + reuse: SafeCoBrowser adds per-project containers and recordable, replayable recipes.
SafeCoBrowser is best when
- The task needs your logged-in state (dashboards, admin panels, tools with no API).
- You want explicit, revocable, audited control.
- You want to use Claude Code or Codex, not a fixed automation runner.
Playwright MCP is best when
- You want clean, reproducible automation in a throwaway browser.
- You're writing tests or scripted flows from scratch.
FAQ
- Does SafeCoBrowser use Playwright?
- No. SafeCoBrowser drives a real Chromium session via the Chrome DevTools Protocol behind a permission broker, rather than exposing raw Playwright automation.
- Can I use my logged-in session with Playwright MCP?
- Not as its default model — it favours fresh automated contexts. SafeCoBrowser is built specifically around your real logged-in session with permission and audit.
