Enhanced debug logging for Unity, with file export and HTML viewer.


  • Output Unity debug info to log files (csv, tsv, json, txt)
  • A nice web interface to view the log files (csv, tsv, json)
    • HTML5 (single file)
    • No external dependencies
    • Searchable via message, stacktrace, timestamp, logtype
    • Filterable by logtype
  • Be able to drop it into existing projects

How to use

  1. Import the latest release's package into your project
  2. Move the prefab Unity File Debug into your scene
  3. Setup the filepath and settings in the inspector
  4. Copy the HTML to your output path via inspector button
  5. Use Debug.Log as normal, or for more advanced usage see Tester script in Demo folder
  6. Open the UnityFileDebugViewer.html file from your log folder, browse for a log file from the top left

If you don't specify an absolute filepath, Application.persistentDataPath will be used.

HTML viewer is designed for modern browsers (chrome/firefox)
