Open a 50 GB log. Start reading straight away.

Measured, not promised

In our published benchmarks of the editor engine, a 50 GB log opened in about 10 milliseconds while the engine used around 40 MB of memory. In the full app window, the same file opened in about 17 milliseconds. Counting through all of a 10 GB file took about a second. These are engine benchmarks on an Apple Silicon Mac with a warm disk cache; your results depend on your Mac and disk, and there is no fixed maximum file size.

Built for the size you have

• Size modes switch automatically: normal files get every feature, large and very large files keep scrolling, search and navigation fast.
• Files with no line breaks, such as minified JSON, are detected and handled safely.
• Jump to any line or byte offset instantly, even deep inside a huge file.
• Search, count matches and replace across the whole file, with progress you can cancel.
• Your original file is never touched until you choose to save.

Good for

• Application and server logs
• Database dumps and SQL exports
• Large CSV and JSON exports
• Build output and crash reports
• Any text file other editors refuse to open
