I design and build software tools that solve problems I run into as a solar homeowner, a privacy-conscious browser user, and a developer managing dozens of repositories. Every product ships with source code, documentation, and the reasoning behind each design decision.

  • PowerBeat: A concept for what a Home Energy Manager should look like: solar, battery, EV charging, and daily production decisions in one interface.
  • PowerNight: Automates overnight Tesla Powerwall grid charging so you use cheap energy during expensive hours. Runs locally via Docker.
  • Clean Autofill: One-click email autofill for catch-all domains. Unique addresses for every site, zero typing, fully offline.
  • Git-Same: Keep your local folders in sync with your GitHub orgs. One command, interactive TUI, parallel cloning.

About

I’m Manuel Gruber, a product manager who builds the tools I wish existed. These projects reflect real problems I encountered with home energy fragmentation, email privacy, and developer workflow friction. More on my background at ManuelGruber.com and LinkedIn.
