The most advanced browser-based schematic editor ever built. AI analysis, real-time SPICE simulation, and professional exports — in one click.
From hobbyist to aerospace — CircuitLab Pro adapts to your workflow with unmatched depth and speed.
"Switched our entire firmware team from Eagle to CircuitLab Pro. The AI analysis alone saved us from 3 costly PCB respins. The speed is absolutely insane."
"I've been designing circuits for 22 years. CircuitLab Pro is the first tool that feels like it was built by engineers FOR engineers. The SPICE engine is brutally fast."
"Our university lab uses CircuitLab Pro as the standard. 400+ students, zero installation issues. The collaboration features transformed how we teach circuit design."
"As a solo maker I can't afford expensive EDA tools. CircuitLab Pro's Pro plan gives me everything Altium does for a fraction of the price. Export quality is exceptional."
"The 50k component library with real SPICE models saved weeks of research. Automatic BOM generation integrated directly with our procurement system. 10/10."
"Real-time collaboration is a game-changer. Our Berlin and Seoul teams now design on the same schematic simultaneously. Version history saved us after an accidental deletion."
