Never lose code to power outages – offline-first sync for Ghanaian devs
Ghanaian developers lose unsaved code and experience downtime with cloud-based tools like VS Code and AWS due to frequent 'dumsor' power outages.
DumsorSync is a PWA that mirrors your VS Code and AWS projects locally in browser storage, auto-saving every 15 seconds. It queues changes during outages and syncs seamlessly when power/internet returns. Works with any cloud IDE without extensions.
