Backlott is a lightweight browser previewer for animation files with support for Lottie JSON, dotLottie, SVG SMIL, and GIF (with reduced functionality).
Your files stay in your browser. Backlott reads them locally and does not upload your animation files to a server.
This app was made with the assistance of AI coding tools, but human attention and care was taken to keep the app lean and pleasant to use. It is provided as-is.
