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