CircuitLab Reviews

Feedback from users evaluating CircuitLab leads us to discover that there are many problems with this PCB design software. Users generally feel that the software is not truly free, and that they are asked to pay a high subscription fee once they register, which seems extremely unfriendly to users who want an easy way to get started. In addition, while users generally found the interface to be simple and easy to use, and the editing tools to be intuitive, many expressed disappointment at the lack of documentation support and feature updates, particularly the lack of PCB design features and file import/export options. Meanwhile, development of the software seems to be at a standstill, and the active user community is calling for more support and improvements. Overall, user reviews of CircuitLab show a more negative bias.

• Not worth it, recommend another program :)They try to pretend it's free, but after a few minutes they force you to create an account. Suddenly locked out while working on a complex project.
• It's a total scam.This site is not free at all. After creating a circuit, it will ask you to pay a hefty subscription fee.
• BAD EXPERIENCE.Initially thought I could use it for free, forced to register after I started designing circuits, and then asked to pay in order to continue using it.
• Fraudulent marketing tactics :.When I first signed up I thought I would be able to design circuits and soon found out there was a fee.
• Unreliable.Very disappointed in this company and will be forced to pay a fee after signing up.
• Regarding the development of the software.Developers were struggling to keep CircuitLab up and running and could only develop at night and on weekends.
• Feedback on the book.Many users have given feedback that they would like better starting material, and the text book addresses just that.
• Disappointment with lack of functioning/I am disappointed with the use of the subscription fee and wish the online simulator was updated with more features.
• Community Activity.Despite the seeming stagnation of development, the community still seems to be active.
• User Interface Rating.CircuitLab's editing tools are very intuitive and easy to use, and are the easiest schematic editor I've ever used.
• Easy to learn and use.I started using CircuitLab in February 2012 when it was first released, and while it made progress quickly, it has stagnated since then. Pros are easy to learn and easy to use; great looking circuit diagrams.
• Insufficient documentation support.Lack of documentation support, no ability to import vendor .su side circuit models, and only very limited symbol creation support.
• PCB not supported.Another drawback is that there is no PCB support, and all work done in CircuitLab is completely limited to that platform, with no ability to import or export data.
• CircuitLab is not working properly.I've tried running CircuitLab on various computers, browsers, and in stealth mode, but it never works. Editing an existing schematic jumps to an error page.
• Open Source Recommendations.Perhaps CircuitLab could consider opening up the source code for their now-abandoned tool? That way we could make some small improvements to a tool that hasn't been updated in years.

Articel Comments

All things considered, my rating for CircuitLab is ★★★★☆. Although the software is easy to use and powerful, some major issues, such as fees and lack of necessary documentation support, seriously affect the user experience. I hope its development team will take this feedback seriously and continue to improve the software to increase user stickiness.

• Friendly User Interface.CircuitLab's interface is designed to be simple and straightforward, making it easy for users to get started in the process of circuit design and simulation, especially for beginners.
• Powerful Features.The software supports mixed-mode simulation and high-quality output to meet the needs of multi-scenario circuit design, and is one of the essential tools for electronic engineers.
• Fee issues.Despite claiming to be free, the actual use of the program requires users to pay a fee, which deteriorates the experience for those who wish to simply get started and creates user dissatisfaction.
• Lack of documentation support.The software's documentation support is relatively inadequate, and users feel overwhelmed when solving specific problems or learning in depth, resulting in a steep learning curve.
• PCB design not included.Although it is convenient for circuit simulation, it lacks PCB design function, users can only complete the project within the platform, and it lacks the flexibility of importing and exporting data, which limits the scope of use.

Despite its feature-rich approach to circuit design and simulation, CircuitLab has faced a number of user feedback issues, especially those involving fees and feature limitations. When comparing other circuit simulation tools, CurveLab, despite its advantages, needs to continuously improve the user experience to better meet market demands.
