JointJS Reviews & Product Details

JointJS is an excellent diagram software. Out of the box, it provides all the core diagramming functionality, making it easy to get started without having to build everything from scratch.

One of the biggest advantages has been the speed of development. Instead of spending a large amount of time creating core diagramming behavior ourselves, we were able to focus on building the parts of the application that are specific to our needs. That made the overall development process much faster.

Performance is also a major strength. JointJS is fast, responsive, and handles diagram interactions smoothly, which is especially important when building more advanced or interactive diagram applications.

Another thing that really stood out was the quality of the demo diagrams. Being able to take one of the existing demos and build off of it made development even more efficient. Rather than starting from a blank canvas, we could use a working example as a base, learn from how it was structured, and quickly adapt it to fit our own use case.

Overall, JointJS has been a great choice because it combines strong out-of-the-box functionality, fast development time, great performance, and practical demo examples that help accelerate a project. Review collected by and hosted on G2.com.

The main downside is the learning curve when working with more advanced custom diagram behavior. It can take some time to understand how to best structure and customize everything for a specific use case. However, that flexibility is also what makes it powerful for building our SCADA diagrams.

"What I like best about JointJS is its flexibility and powerful diagramming capabilities. It allows us to build highly interactive and customizable diagram-based applications with ease. The library is well-structured, supports a wide range of diagram types (like flowcharts, UML, BPMN), and integrates smoothly into our frontend stack.

Additionally, the built-in support for SVG rendering and the ability to extend functionality through plugins make it a great fit for our project's evolving needs. Even with complex diagrams, JointJS remains performant and developer-friendly." Review collected by and hosted on G2.com.

“Overall, I find JointJS to be an almost perfect diagramming library — well-designed and surprisingly easy to get started with. What stands out most is the excellent help center; the guides and examples are clear and practical, allowing developers to learn and implement features quickly.

One small suggestion for the team:

It would be even more helpful if JointJS learning resources could be integrated into major AI coding assistants (like GitHub Copilot, ChatGPT, or Claude). This would lower the learning curve further and help developers discover features and solutions more intuitively.” Review collected by and hosted on G2.com.

Diagrams look great and work really fast. I'm building a product for my early-stage startup and needed solid UML diagrams - tried a few other libraries but JointJS was the only one that actually worked well for what I needed. Clean API, good docs. Review collected by and hosted on G2.com.

Price is a bit steep when you're bootstrapping a startup. Would love to see more affordable options for small teams. But honestly, I couldn't find anything better, so here we are. Review collected by and hosted on G2.com.

As a UI designer, what excites me most about JointJS is the level of visual customization it offers. We can imagine and design diagrams to look exactly how we want, which for a design shop like ours is essential. We also practice vibe coding for prototyping with our clients, and JointJS fits perfectly into that workflow, giving us the flexibility to quickly bring ideas to life. The documentation, demos, and examples clearly show how powerful and adaptable the framework is for tailoring visuals, interactions, and behaviors — exactly the kind of freedom we value in our projects.

We still need to get deeper into the framework, but as non-developers the only challenge might be that, because it’s such a feature-rich tool, the learning curve can feel steep at the beginning. That said, the quality of the documentation and examples really helps smooth that out, and thanks to the same good documentation, Cursor has been able to help us navigate and ramp.

JointJS has become the foundational diagramming library for my product. It's fast, has robust controls, multiple layout options, and is easy to use. Review collected by and hosted on G2.com.

It's difficult to integrate React components natively into the graph through foreignObject. Review collected by and hosted on G2.com.

JointJS has been an exceptional library for integrating interactive diagramming capabilities into my application. Its power and flexibility make it an ideal choice for developers looking to build customized and user-friendly visualizations. Review collected by and hosted on G2.com.

Documentation: While the documentation is comprehensive, it can be challenging to find examples for specific use cases, requiring additional experimentation.

Complexity: Managing complex diagrams with multiple layers of customization can become cumbersome, especially when dealing with dynamic updates and interactions Review collected by and hosted on G2.com.

JointJS is an extremely powerful tool when it comes to creating complex diagrams and interactive visualizations. The flexibility is particularly noteworthy: with the open-source version, many use cases can already be covered – from flowcharts to custom diagram types. The multitude of features and the possibilities for extension are impressive. Review collected by and hosted on G2.com.

The learning curve is relatively steep. Especially the beginning requires time and patience. Although there is an open-source version, the documentation focuses heavily on the premium version (JointJS+). Many examples and functions are described there, which does not always make it easy for users of the free version. Additionally, the price for the premium version is quite high – especially for startups, this poses a real hurdle. Nevertheless, we will upgrade to JointJS+.

JointJS is a very flexible and powerful tool for creating interactive diagrams. It is particularly noteworthy how well JointJS integrates with modern frontend frameworks like Vue – this makes development in existing projects significantly easier. Even with the open-source version, a lot can already be achieved: from classic flowcharts to custom visualizations. Review collected by and hosted on G2.com.

The entry is not quite easy. The learning curve is steep and the documentation focuses heavily on the paid premium version (JointJS+), which makes it more difficult to fully utilize the open-source version. Many advanced features are mentioned, but not sufficiently explained in the open-source context. Also, the price for JointJS+ is relatively high for young startups – here you have to carefully consider whether it is worth it. Review collected by and hosted on G2.com.

The amount of features and the quality of the documentation is outstanding. It took me less that three days to completely migrate our app from React Flow, and I even was able to add several new features in the process. I cannot recommend it highly enough. Review collected by and hosted on G2.com.

It's unfortunate that the documentation is not available as Markdown or PDF, so that it could be easily added to a projects docs folder and accessed by an LLM. Review collected by and hosted on G2.com.

What I like best about JointJS is its exceptional performance and extensive functionality. It's also very user-friendly, making it easy to get started and build diagrams quickly. It's incredibly fast, delivering smooth, responsive interactions even with complex diagrams. JointJS provides the richest set of features among all diagramming libraries I've used, including excellent support for custom shapes and powerful automatic layout capabilities, which make it extremely flexible and adaptable to various needs.

Moreover, JointJS integrates seamlessly with Angular, further enhancing its usability in modern web applications. The library itself is mature and reliable, backed by thorough and well-organized documentation, along with numerous practical examples that significantly reduce the learning curve.

Finally, the support team behind JointJS is outstanding—they're always helpful, responsive, and effective in resolving any issues. In my experience, every problem I've encountered has had a satisfactory solution. Overall, JointJS consistently exceeds my expectations, making it my top choice for diagramming projects.
