Hey Product Hunt! 👋Robert here, maker of Log4jAnalyzer.I'm an HP Indigo Application Engineer, and I built this because I was genuinely frustrated. Every time our presses had issues, I'd need to: Boot Windows emulation (on my Mac) Open Chainsaw or Log4View from 2008 Manually try to correlate timestamps across 5+ log files Lose my sanity The breaking point was a 4-hour debugging session where I knew the answer was in the logs, but I just couldn't see the connection between systems.What makes this different:The core innovation is timestamp synchronization. Open your API gateway logs, database logs, application logs - whatever you need. Click any row. Every other window instantly shows what was happening at that exact moment across your entire system.I spent months optimizing SwiftUI Tables to handle massive files (we're talking 5GB+) without performance degradation. The result maintains 60fps no matter what you throw at it.Technical Details:For the developers here, the biggest challenge was SwiftUI's Table performance with large datasets. I implemented: Research-based pagination that only renders visible rows + buffer Binary search algorithms for O(log n) timestamp matching GCD-based file system monitoring for live tail Sophisticated memory management for multi-GB files I'm here all day to answer questions!Common questions I'm expecting: "Why not just use grep/awk?" - You can! But when you need to correlate 10 files and see the visual timeline, this is faster "Why not open source?" - I'm considering it, but want to validate the product first "Windows version?" - macOS-only for now, built specifically for native performance Try the free version - it's genuinely useful, not a crippled demo. The Pro version removes limits for professional workflows.What questions do you have?
