LogLineAlign

Merge log files from different time zones into one unified timeline, entirely in your browser

Problem

Debugging often means juggling logs from multiple services and time zones with inconsistent timestamp formats, making manual conversion and sorting painful. Existing log tools usually require uploading data or deploying heavy services, raising privacy and cost concerns.

Solution

A local-first web tool that auto-detects common timestamp formats, normalizes them to a user-specified time zone, and merges multiple logs into a single chronologically ordered view. Files never leave the browser.

Users

Backend engineers, SREs, and ops people who debug across teams and regions

MVP

Auto-detect several common timestamp formats; manual time zone offset override; drag in multiple log files and merge-sort them; all local, no upload; export merged text

Revenue

Free open-source core; paid subscription for team sharing, saved parsing templates and larger file support

Why now

Distributed systems and remote work make cross-time-zone debugging routine, yet lightweight, privacy-friendly log alignment tools remain scarce; a solo developer can build one with pure front-end tech
