  Hey HN, I often check raw logs - out/error.log, nginx's access.log, etc, but they're hard to read So I built beautiful parser & formatter with filtering and syntax highlighting PrettyLog supports many common log formats out of the box: - nginx access logs - Apache error logs - Syslog (RFC 5424) - Logfmt (Heroku/Go style) - Docker logs - standard/node.js logs - Spring Boot logs - AWS VPC Flow logs - Kubernetes kubectl get events If you need something specific, you can use custom regex parser. Processing is 100% local. Your data never leaves the browser. I hope you find it as…

  LogLayer – Unified logger that routes logs to various logging libraries2025 · loglayer.dev · ▲56

  As a longtime TypeScript/Node.js developer, I've often faced challenges with logging—choosing, using, and maintaining the right logger for various projects. While most loggers offer the usual methods like "info", "warn", and "error", they vary significantly in how they handle structured metadata or Error objects. This can lead to ad-hoc solutions, like serializing errors or writing custom pipelines, just to get logs formatted correctly. I built LogLayer to address these pain points by introducing a fluid, expressive API. With methods like "withMetadata" and "withError", LogLayer…

  Hi HN, I'm the creator of LogLens. Like many of you, I spend a lot of time digging through massive structured (mostly JSON) log files. I've always relied on grep for its speed and then piped to jq for the actual filtering, but I find this workflow gets slow and complicated, especially with multi-GB files or complex queries. LogLens is my attempt to fix this. It's a single, fast CLI tool written in Rust that's designed specifically for structured logs. It combines a simple SQL-like query language (e.g., loglens query './logs' 'level == "error" && status >= 500') with parallel,…

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
