HL: The Fastest Rust-Based JSON Log Viewer - 2GiB/s Parsing Speed & More! (2026)

Unleash the Power of Log Management with hl: A Rust-Powered Log Viewer

In the world of DevOps, efficient log management is crucial, especially when dealing with massive log files. Enter hl, an open-source log viewer built with Rust, designed to revolutionize the way you handle structured logs. With its impressive parsing speed of up to 2 GiB/s, hl is a game-changer for anyone working with large-scale log data.

But here's where it gets controversial: hl's creator claims it outperforms popular alternatives like hlogf, humanlog, fblog, and fblog-d. This bold statement has sparked debates among developers, leaving many curious about the truth behind these performance claims.

And this is the part most people miss: hl isn't just about speed. It's an all-in-one solution packed with features that make log management a breeze. With its integrated pager, you can effortlessly browse through log entries, and its rich set of filtering, searching, and sorting capabilities ensure you find exactly what you need.

One of the standout features of hl is its ability to handle complex queries. Using a combination of logical, comparison, and string operators, you can create powerful filters to analyze your logs. For instance, you can easily identify log entries with specific error levels or field values, making troubleshooting a snap.

Furthermore, hl allows you to explicitly manage missing fields in your queries. This level of control ensures you get accurate results, even when dealing with incomplete data.

In a recent discussion on Hacker News, user solatic praised hl as a simple yet effective alternative to complex tools like Grafan Loki. They highlighted the benefits of hl's ease of use, especially for scenarios with a single app instance. However, they also acknowledged the value of centralized log management for multiple machines, suggesting ssh multiplexing as an alternative.

With its impressive performance, feature-rich capabilities, and user-friendly nature, hl is a must-have tool for any DevOps engineer. Give it a try and experience the power of efficient log management.

So, what do you think? Is hl the future of log viewing, or are there other tools that deserve the spotlight? Let's discuss in the comments and share our experiences!
