eSim (formerly known as Oscad / FreeEDA) is an open-source EDA (Electronic Design Automation) tool that offers circuit design, simulation, analysis, and PCB (Printed Circuit Board) design functionalities. It is built with open-source software such as KiCad and Ngspice and is released under GPL. eSim provides similar capabilities and ease of use as equivalent proprietary software in the market, making it an affordable alternative for educational institutions and small to medium-sized enterprises.

I have personally used eSim for circuit design and PCB layout and found it to be a reliable and powerful tool. The integration with KiCad for circuit design and Ngspice for simulation makes the workflow seamless and efficient. The interface is user-friendly and intuitive, allowing both beginners and experienced users to navigate through the software with ease.
