Whaile: Large File Log Viewer
Open multi-GB log, text & CSV
$24.99
Open an 8 GB log in a second, not minutes. Scroll without lag, search the whole file, jump to any line, and let your AI assistant read it too.
Whaile (yes, like the whale) swallows files whole. The multi-gigabyte logs and text files that crash TextEdit and choke VS Code open here in about a second. The ones you'd normally only dare to touch from the terminal.
It's native on Mac, iPad and iPhone. Whaile memory-maps the file instead of loading it into RAM, so an 8 GB log opens right away and scrolls smoothly from the first line to the last. No "file too large" error, no progress bar to stare at.
WHAT IT DOES
• Opens 1 GB, 8 GB or bigger files in seconds
• Scrolls smoothly, even 50 million lines in
• Searches the whole file and highlights every match
• Jumps straight to any line number
• Barely touches your RAM: the system pages data in and out as you scroll
• Sandboxed and offline, so your files never leave your device
WHO IT'S FOR
• SREs and platform engineers digging through giant nginx, syslog and crash logs
• Data engineers spot-checking a 2 GB JSONL, NDJSON or CSV dump before running the real pipeline
• Anyone who got sent a log or an export that's too big for their usual editor
LET YOUR AI READ THE FILE
On Mac, Whaile has a built-in MCP server: switch it on in Settings and AI assistants like Claude can search and read huge files directly, without blowing through their context window. Point your agent at a 10 GB incident log and ask what went wrong, instead of scrolling through it yourself.
WHY IT'S FAST
• Memory-mapped access: nothing gets loaded or copied up front
• A sparse line index, built in the background, makes jump-to-line instant
• Byte-level search written for files that don't fit in memory
Whaile is read-only on purpose. It does one job: open, read and search the files that are too big for everything else.
