As answered by people managing VoltPlan.app and SourceForge.
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.
