Show HN: Jsonl Viewer Pro – Open 5GB Security Logs Instantly on Mac

3 points by hilti 2 months ago · 0 comments · 1 min read

Native Mac app for analyzing massive JSONL files (Suricata, Zeek, EDR, CloudTrail logs). Opens 5GB+ files in seconds, automatically flattens nested JSON into filterable columns, supports advanced queries like "alert.severity <= 2".

Built with C++ + simdjson for actual native performance, not Electron. 6MB app, zero telemetry, data stays local.
