Delta updates for electron apps

Provide blazing fast update experience for your users. It reduces the bandwidth usage by 90%. Users download only the delta. It uses binary diffing (HDiffPatch) to generate the delta.

Get Started

It's an electron-builder plugin


True delta updates

@electron-delta/builder uses binary diffing instead of blockmaps of electron-builder. Thus the delta size is a lot smaller. Basically whatever you have changed is shipped to the user.

  • Uses binary diffing
  • Do more releases
  • Faster update experience

Save bandwidth cost

If you have 1000 active users and everyone downloads 40 MB for each release and you do 2 releases/week then total bandwidth consumption for a month would be (40 MB x 4 x 2) x 1000 Users = ~312 GB .


One time payment. I have spent nearly two years building this solution. 14 days money back guarantee.

Sandeep profile picture

It's being deployed in production with thousands of users and running smoothly. The delta update mechanism based on the blockmap approach uses a very good amount of bandwidth. The binary diffing approach works better and downloads only the diff, generally less than 1MB to update the app.
