Lumber: Encrypted Logs

Server Logging for Developers

Free

Your logs are encrypted on your own servers, and only your devices hold the key. Lumber's servers keep ciphertext they can't read. 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 No ads and no tracking.
