(3)4.2/5

Flux is browser-based PCB design software (EDA) with a built-in AI copilot that works as a hardware co-designer. It generates schematics from natural-language prompts, selects and places components, routes traces, and runs design rule checks, taking a project from idea to manufacturable board in one tool. There is nothing to install: projects run in the browser with real-time multi-user collaboration. Core capabilities: - AI copilot for schematic generation, part selection, placement, routing, and design review, including full plan-to-layout workflows from a text prompt - Schematic capture and PCB layout with live design rule checks - Real-time collaboration: multiple engineers can work in the same project simultaneously - Component library with sourcing data, plus BOM and Gerber export for manufacturing - Import support for Altium and KiCad projects Flux is used by startups, hardware teams, and individual engineers as an alternative to desktop EDA tools such as Altium Designer and KiCad, and by teams migrating off Autodesk EAGLE after its retirement in June 2026. As of 2026, Flux has 1.1 million registered builders and 6.4 million projects. Pricing: paid plans from $20 to $158 per month, with AI features metered through compute credits included in each plan. Free 14 day trial to start.
