It is widely used in academia because its visual simulation environment helps students grasp complex electronics concepts without needing physical hardware.
While there is no permanent free version of Proteus, the official trial offers an excellent opportunity for students and professionals to learn the interface and simulate complex circuits. For long-term use without cost, transitioning to open-source tools like KiCad is the best path forward. proteus free version download

If you cannot afford a license and the trial period expires, consider these open-source alternatives:
Many universities have site licenses. If you are a current student, check your university’s IT portal. Some institutions allow students to download a limited-feature version for the duration of their course.
Microcontroller simulation is restricted to a 14-day evaluation period due to past abuse.
