Compare Caxton vs. UltraEdit

Caxton is a native macOS large file text editor and CSV editor in one: a workbench for logs, CSVs, TSVs, JSON, SQL dumps, and exports of any size. One app instead of a text editor, a spreadsheet, and a log viewer: open the file and work. Every delimited file opens as text and as a typed grid; edits made in either view show in the other, and saving writes the same file back. Nothing is imported, converted, or uploaded. It memory maps the file instead of loading it into RAM. On an M1 Max a 50 GB log (403 million lines) opens immediately, indexes in 75 s, and memory stays under 160 MB throughout. A search returns 8,059,509 matches counted exactly; Replace All across 1,574,039 sites is one undo step. A 10 million row CSV (5.1 GB) opens as a sortable, filterable grid in 4.4 s, past Excel's row limit. Every number, including a run on a base 8 GB M1 Air, is published with its methodology at caxton.app/docs/benchmarks. Text: find and replace with exact counts and regex, Batch Replace, Find in Files, filters that keep line numbers, a log viewer mode with Go to Time and severity filters, follow mode, side by side compare, multi-cursor editing, snippets, clipboard history, 18 encodings. CSV: typed sorting, filter by value, fill series, remove duplicates, split and combine columns, change the delimiter, fixed-width to columns, cell editing in place. Native AppKit and Swift, no Electron. Files never leave the Mac: no upload, no cloud processing, no telemetry. Apple Silicon and Intel, macOS 13 or later, a 5 MB notarized download, also installable with Homebrew. Built for data engineers, SREs, DBAs, and analysts. 7-day trial, no card. After it, opening, searching, filtering, and copying stay free; a license adds editing and saving.

UltraEdit has spent more than 30 years serving users who work beyond the comfort zone of general-purpose editors. It is widely used for tasks such as handling very large files, manipulating complex text and data, and supporting workflows where sensitivity, control, or reliability matter more than they do in everyday editing. For individual professionals, UltraEdit is often the tool people reach for when standard editors start to feel limiting — whether that means repetitive advanced edits, heavier files, or more demanding data work. For organizations, it fills a different role: a commercially supported editor for sensitive workflows and regulated environments such as banking, insurance, healthcare, government, and other settings where unsupported tools create too much uncertainty. Today, UltraEdit reports more than 4 million users worldwide and is used by enterprise customers across the Fortune 100, 500, and 1000.
