On my first day of using the website, I could use a lot of things, but after that, I can’t do anything. For example, when I add 2 risitors, the website tells me to use the purchased plan. I need to know how to use the free plan and what it can do

DCACLab is a self-funded project (no investors or grants), so we can’t provide full free access—we need to cover AWS server costs, development time, and maintenance to keep simulations running reliably for students worldwide.
After signing up, you get a limited time of free trial which allows you to use all components and features except the Save feature .
Once the trial expires, you will be able to use one (1) piece of each component except :
- Multimeters
- Oscilloscope
- Wattmeter
- Integrated Circuits (555, LM317)
- Integrated Circuits Creator
- Analysis (Kirchoff, DC Sweep, Time Domain)
- Save
We have 2 paid plans: Starter and Premium.
The Starter plan has all components and features except :
- Digital multimeter
- Oscilloscope
- Wattmeter
- Integrated circuits and integrated circuits Creator.
- Analysis (Kirchoff, DC Sweep, Time Domain)
The Premium plan has all features and components.
To summarize, all paid plans allow you to save circuits, but the Premium plan has more components suitable for advanced electricity/electronics work.

We hope that answers your question
