Why LogoRRR
Developers who want visual, local-first analysis of multi-gigabyte logs in a cross-platform desktop GUI.
- Platforms
- macOS, Windows, Linux
- Local / offline
- Files are processed on the desktop; no server is required.
- Trade-offs
- No regular-expression search, remote ingestion, triggers, or AI assistance.
- Line-oriented analysis does not provide rich JSON/XML field parsing.
- Multiple files open together, but are not chronologically merged into one stream.
