Free local tool for previewing 2D PNG sequence effects

Hi everyone,

I made a free local-first tool called VFXRun Browser for previewing 2D PNG sequence effects before bringing them into a game engine.

It scans local folders, groups PNG sequences, and lets you preview them as animations instead of guessing from static thumbnails.

Useful things it can do:

  • Browse local VFX folders
  • Preview PNG sequences and GIF effects
  • Search and filter by filename, color, or effect type
  • Save favorites
  • Open the original folder
  • Test effects with a background, character, or object
  • Export edited results for your normal engine workflow

Files stay on your computer. No upload and no account required.

There is also SheetGen, a free online sprite sheet packing tool:

I’d be interested to know if this is useful for Defold users working with 2D effects.
