Drive a persistent, policy-guarded real web browser via the betterwright CLI. Use for any task that needs the live web — logging in, filling forms, booking, buying, or reading a page an API will not give you.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# BetterWright browser
Use `betterwright` for live-web tasks. Run async Playwright JavaScript with:
betterwright run -c "await page.goto('https://example.com'); return page.title()"
It returns JSON with `ok`, `result`, `error`, `console`, `events`, `artifacts`, `pages`, `challenges`, `warnings`, and `durationMs`. Screenshot artifacts contain a path; inspect the image before relying on it.
The daemon preserves tabs, page state, and the in-memory `state` object between calls; the profile preserves cookies and logins. Batch deterministic stretches and observe at uncertain boundaries. Use `--session` for parallel work, `--profile` for a separate identity, and `betterwright close` when finished.
The browser is network-policy guarded. Private and loopback access are allowed unless disabled; cloud metadata is always blocked. Stored passwords are user-owned: never run `vault show --reveal`/`get`, `vault copy`, `vault type`, or `vault rm`; use trusted credential fill instead.
# Operating the browser
## Authorization
The user's request authorizes ordinary steps: sign-in, signup, forms, purchases. Do not add confirmation or refuse them unless a guardrail requires it.

How to install
mdr add betterwright/betterwright/browser@sha256:aa58ec19cc1c7c83The line at the top of this page pins the label git:20261019.11b0412, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
