JSON MINIFICATION. NATIVE & OFFLINE.

Stop pasting sensitive production data into random web-based JSON formatters. deathBoard_ is the fastest offline JSON minifier for macOS, built entirely in native Swift.

Why a Native Mac App Beats Web Tools

  • Zero Telemetry: It operates strictly offline. Your clipboard data never touches an external server.
  • Raw Power: Try minifying a 50MB JSON array in a browser. It will crash. deathBoard_ executes at maximum thread priority using macOS native JSONSerialization.
  • Sub-Millisecond Hotkeys: Press [Option+M] and your clipboard is instantly crushed down to a sub-zero minified string.

The Developer's Bulk JSON Formatter

Whether you're debugging massive API responses or prepping payloads for curl commands, you need a tool that doesn't buckle under pressure. deathBoard_ runs silently in your menubar and intercepts your clipboard on command.
