About the startup
Caxton is a native macOS text editor built for files that break everything else, multi-gigabyte logs, CSVs past Excel's row limit, SQL dumps, minified single-line files. It memory-maps files instead of loading them, so a 10GB / 80M-line log opens immediately, a full-file search returns 1.6M matches in 1.3s, and memory stays under 200MB the whole time. Large CSVs open as a typed, sortable grid — 2M rows parse in 2.6s — with header-click sorting, dedupe, and split/combine. Native AppKit, no Electron, notarized, works fully offline. Benchmarks and methodology are published at caxton.app/docs/benchmarks. 7-day free trial, no card, no account. $9.99/mo, $99.99/yr, or $179.99 lifetime, and if a subscription ever lapses, your files open read-only, never locked.
