Lumber: Encrypted Logs

Read your servers' logs on iPhone and iPad, end-to-end encrypted. Logs are encrypted before they leave your server, and only your devices hold the key, so Lumber's servers store nothing they can read.

SEE WHAT'S HAPPENING
• Every app at a glance: its last 48 hours of activity, with new logs, errors and fatals counted
• A heatmap of each app's days or hours, with a count for every level
• Logs set like terminal output, newest at the bottom, colored by level
• Filter by level, pick a day on a calendar, search the text, and flag the logs that matter
• Open a log for its message, request and trace IDs, context and metadata, and copy it as JSON

WORK IT OUT TOGETHER
• Write notes about a log, and your team's replies thread under it
• Invite teammates as admins or members, and guests to a single app
• Share an app with your whole team, or keep it to yourself

STAY AHEAD OF PROBLEMS
• Push alerts when an app logs an error, with a level for each app
• Fatal alerts are Time Sensitive, so they get through Focus
• New logs stream in while Lumber is open
• Live streaming and push alerts depend on your team's plan

ENCRYPTED END TO END
• Logs are encrypted with AES-256-GCM on your server, with a key made on your device
• Teammates get each app's key encrypted to their own account key
• Link a new device with a short code from one you already use
• Confirm a teammate's new key with a code before your devices share anything with it

SEND YOUR LOGS
• Create an app here, add an API key, and give it to Lumber's Node.js package (@infinitetoken/lumber) on your server
• On a Mac, the lumber command reads your logs in the terminal and hands them to AI agents over MCP, decrypted on your Mac

MAKE IT YOURS
• Dark or light, with an accent color of your own
• A color and logo for each app
