In their own words
CircuitLab
CircuitLab provides in-browser tools for schematic capture and circuit simulation for students, hobbyists, and professional engineers. It supports analog, digital, and mixed-mode simulation, plus 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 make it possible to share designs or ask for help.
CircuitLab runs on Windows, Mac OS X, and Linux and works in a browser on iPad. Its membership information also describes offline access through the Chrome Web Store and SSL-encrypted access. It offers a free plan and paid subscriptions, including Micro at $24 a year, Hacker Lite at $16 a month, Hacker at $26 a month, and Pro at $39 a month. The pricing note lists a starting rate of $2/mo (annual). Commercial use is permitted with Pro and Enterprise subscriptions; otherwise, the terms describe use as personal and non-commercial unless otherwise specified.
