Cost
Depending on the features and scale of use, the platform can become costly, especially for small businesses or startups with limited budgets.
Learning Curve
While the platform is user-friendly, there may still be a learning curve for users unfamiliar with e-commerce tools or new to managing an online business.
Limited Support
Some users have reported that customer support can be slow or insufficient, impacting their ability to resolve issues quickly.
Feature Overload
For some small businesses, the extensive features may be overwhelming and unnecessary, leading to underutilization of the platform's capabilities.
Dependence on Internet Connectivity

Free and Open Source
Numbas is a free, open-source e-assessment system, making it accessible to educators and institutions without licensing costs. The open-source nature also allows for community contributions and customization.
Mathematical Focus
Numbas is specifically designed for mathematics and STEM subjects, offering robust support for mathematical notation, randomized numerical questions, and sophisticated marking algorithms that understand mathematical equivalence.
Randomized Questions
Numbas supports extensive question randomization, allowing educators to create template questions with randomized variables. This means each student can receive a unique version of a question, reducing the risk of cheating and enabling repeated practice.
LMS Integration
Numbas supports LTI (Learning Tools Interoperability) standards, making it easy to integrate with popular learning management systems like Moodle, Canvas, and Blackboard for seamless grade passback and student tracking.
Browser-Based and Offline Capable
Numbas exams run entirely in the web browser and can even be downloaded for offline use. This makes them highly portable and accessible without requiring students to install any special software.

Steep Learning Curve
Creating complex questions with advanced randomization and custom marking can require a significant learning curve, particularly for educators who are not comfortable with programming concepts or the JME expression language used by Numbas.
Limited Non-STEM Application
While Numbas excels at mathematics and STEM-related assessments, it is less suited for subjects that require essay-based answers, qualitative assessments, or non-mathematical content, limiting its usefulness across broader disciplines.
Interface Design
The default user interface and question editor can feel dated or unintuitive compared to some commercial e-assessment platforms, which may discourage adoption by less technically inclined educators.
Limited Community and Support
While there is a community around Numbas, it is relatively small compared to larger commercial platforms. Finding answers to specific problems or getting timely support can sometimes be challenging outside of the core development team.
Setup and Hosting Requirements
While a hosted version exists, institutions wanting full control need to self-host the Numbas LTI provider, which requires server administration knowledge and ongoing maintenance, adding technical overhead for IT departments.
