Peek v0.3.0 — local proxy and safe sharing.

Public previews now route through a loopback proxy that rechecks ownership of the verified dev port, with password protection, WebSocket origin validation, failed-auth throttling, private mode, and optional expiry.

Install: npm install -g @usepeek/peek@0.3.0

0.3.0 — 2026-10-10

  • Route public tunnel traffic through a loopback proxy that rechecks ownership
    of the selected dev port before forwarding HTTP and WebSocket requests.
  • Preserve HTTP framing and reject unsupported WebSocket upgrades with a
    complete response instead of a half-written handshake.
  • Add --password with hidden terminal input and HTTP Basic authentication at
    the proxy. Peek removes the credential before requests reach the app.
  • Throttle repeated failed authentication and validate the browser WebSocket
    Origin against the active preview URL.
  • Add --private for previews without a public tunnel, explicit --public,
    and --expires for automatic teardown after first readiness.
  • Show access mode and expiry in terminal output and JSON events.
  • Explain why a preview is unreachable, including protected-preview and
    HMR/WebSocket diagnostics.
  • Make shutdown deterministic and report the concrete reason when cleanup
    cannot confirm every descendant exited.
  • Bound dev-server and tunnel output buffering, and stream the cached
    cloudflared download and checksum verification to lower peak memory on a
    first run.
