As answered by people managing SoFi and VoltPlan.app.
VoltPlan.app's answer:
VoltPlan is built with Next.js for speed and scalability, DaisyUI for a clean and accessible UI, and PocketBase as a lightweight backend for syncing and persistence. The app is designed to feel fully local and responsive while enabling optional features like cloud saves and sharing.
VoltPlan.app's answer:
VoltPlan combines visual wiring design with smart calculations for wire gauge, fuse size, and battery runtime—all in one easy-to-use browser-based tool. It’s built for real-world 12V/24V setups, not just abstract circuits.
VoltPlan.app's answer:
VoltPlan is free for personal use, requires no signup, and gives you accurate results tailored to vans, boats, and off-grid systems. While others focus on industrial schematics, VoltPlan puts DIY users first—with a library of real-world components and one-click PDF export.
VoltPlan.app's answer:
DIY van builders, boat owners, and off-grid enthusiasts who want to safely plan and share their electrical systems—without spending hours learning electrical engineering.
VoltPlan.app's answer:
VoltPlan started as a tool for designing a boat’s electrical system. Frustrated by spreadsheets and inconsistent advice in forums, we built something better: a clear, shareable, and accurate way to plan real-world 12V/24V installations. Today, it helps thousands build with confidence.
