A native macOS editor for 10GB logs and 2M-row CSVs. Memory-mapped, fully indexed, no Electron.
Caxton is a native macOS editor for the files that other editors refuse: production logs, database exports, two-million-row CSVs. Not a mockup: this is Caxton holding the 10 GB benchmark log. The workflows that have been exclusive to EmEditor on Windows for fifteen years, rebuilt as a native Mac app. Memory-mapped I/O, a piece-table document model, and a tiered line index that scales past 120 million lines. CSV mode auto-detects delimiters, freezes headers, and sorts millions of rows by any column: click the header, get an external merge sort.
