Last year I started pushing the limits of my JavaScript text editor engine – wondering where the performance ceiling really is. Turns out it can go head-to-head with Monaco (VS Code) and CodeMirror in many scenarios.
To show what it can do, I built FlixLines: a web-based log viewer that opens huge files directly in the browser – often faster than klogg (which is a native desktop app).
Real numbers from my 2021 laptop: - 10 GB log opens in ~10 seconds - 20 GB in ~17 seconds - Memory usage under 100 MB - Smooth 165 FPS scrolling on my 4K screen, regex search, bookmarks, highlight rules
Everything happens 100% locally – no uploads, no installation, no server-side processing.
Try the free demo (2 GB limit per file, limited bookmarks & highlight rules): https://flixlines.com/demo-app
Here is a short video showing opening a 10 GB file in ~10 seconds: https://www.youtube.com/watch?v=_ZWFltvotKI

Pro version (unlimited everything) coming very soon – attractive early-bird pricing planned.
Curious to hear your thoughts: what are your biggest pains when dealing with large log files?
Thanks! Kamil
