peekin

A lightweight, read-only file browser for your web browser. Browse a folder and preview images (swipeable gallery), video, audio, PDF, rendered Markdown, and source code with syntax highlighting. Works on desktop and phone. Fully offline.

Run

uvx peekin                     # share the current folder on http://127.0.0.1:8000
uvx peekin ~/Pictures --open   # share a folder and open the browser
python -m peekin               # after: pip install peekin

Share on your network

uvx peekin --host 0.0.0.0

peekin needs a password whenever it listens on something other than localhost. If you don't set one, it generates one and prints it at startup. Set your own with PEEKIN_PASSWORD=... or --password-file FILE. --no-password turns the password off (not recommended on shared networks).

Options

Security

• Read-only: nothing in the shared folder can be changed through peekin.
• Paths cannot escape the shared folder, including through symlinks.
• Five wrong passwords lock that IP address out for 60 seconds, doubling each time.
• HTML and SVG files are downloaded, never rendered, so files you share can't run scripts in peekin.
• Other websites you visit can't read your files through peekin: cross-site requests are blocked, and without a password peekin only answers to IP addresses, localhost, and *.local names.
• No HTTPS: use it on networks you trust, not on the public internet.
