Show HN: LogSieve – A Client-Side Log Viewer (No Back End, No Build Step)
ilovetux Wednesday, November 05, 2025I built LogSieve as a small experiment: Can I build a small, completely client side application to parse and visualize logs.
It turns out the answer is Yes.
Drag and drop a .log or .txt file into the page, and it parses, filters, and visualizes entirely in your browser — no server, no upload, no dependencies. It supports text and regex filters, named-group field extraction, sorting, summary stats, and JSON/CSV export.
You can open it directly on GitHub Pages or just clone the repo and double-click it. Source: https://github.com/notesofcliff/logsieve
Built as a "one-problem" weekend project — it’s basically "just" 900 lines of HTML, CSS, and JS.
Summary
LogSieve is a powerful open-source log analysis tool that provides a user-friendly interface to search, filter, and visualize log data from various sources. It offers a range of features, including real-time data processing, custom dashboards, and advanced analytics capabilities.
