CircuitLab
What CircuitLab is
CircuitLab is a circuit design and simulation tool for students, hobbyists, and professional engineers. It provides schematic capture and supports analog, digital, and mixed-mode simulation, along with frequency-domain analysis and parameter sweeps. Users can import SPICE device models and use CSV files as signal sources. Schematics can be exported as PDF, PNG, EPS, or SVG, and unique circuit URLs let users share designs or ask for help online. CircuitLab runs on the web and lists Windows, macOS, Linux, and extension platforms; membership information also describes use in an iPad browser and offline access through the Chrome Web Store. The service offers a free plan and paid subscriptions. The pricing note starts at $2/mo (annual); listed options include CircuitLab Micro at $24 a year, Hacker Lite at $16 a month, Hacker at $26 a month, and Pro at $39 a month. Pro and Enterprise subscriptions allow commercial use; otherwise, terms describe use as personal and non-commercial unless otherwise specified. Online documentation and community forums are available, and Enterprise support is listed with a response within 24 hours.
