What it is

Pure Trace is an offline log-analysis tool built around a knowledge base + keyword matching: preset keywords auto-detect errors and warnings in your logs, and tapping a matched line opens the linked solution doc — experience becomes knowledge, so every troubleshooting pass follows a playbook.

Logs are parsed entirely on your device and never uploaded to our servers, so you can safely point it at logs containing sensitive information.

Who it’s for

Developers and ops engineers who need to pinpoint issues in large logs
Anyone who handles local log files and wants data to stay local
Teams that want to turn troubleshooting know-how into a reusable knowledge base

Key features

Block search: see matches with surrounding context (adjustable, 3–20 lines) to understand the full scenario
Time-range filtering: quick ranges (last 1h / 6h / 24h), custom windows, and automatic timezone conversion for cross-timezone logs
Automatic keyword matching: highlight errors, warnings, and keywords with custom keyword groups and colors
Minimap navigation: visualize the whole log and jump to any position in seconds
Regex search: flexible pattern matching that hits exactly what you mean
And more: automatic log-level detection, hide-rule filtering, multi-select copy, dark mode
Bilingual adaptive: the UI language drives which language keywords and knowledge-base entries are matched

Why I built it

Log analysis has two classic pain points: data leaving your machine, and hard-won experience evaporating. Pure Trace solves both — logs are always parsed locally, and every pit you’ve climbed out of can go into the knowledge base, ready to match on the next keyword hit.
