Great 2D Physics Library **Rating:** 4.0/5.0 stars **Reviewed by:** Jeff W. | Web Developer, Marketing and Advertising, Small-Business (50 or fewer emp.) **Reviewed Date:** November 09, 2017 **What do you like best about Box2D?** It is a high performance 2D physics engine, great for creating impressive looking games or tech demos. **What do you dislike about Box2D?** The learning curve can be pretty steep for a beginner. You'll need to brush up on basic physics terminology and vector math. Sometimes the code required to create physics objects can get a little verbose. **Recommendations to others considering Box2D:** If you're looking for just a 2D physics engine, then chances are you'll give Box2D a try and love it. If you want features found in a game engine like rendering sprites, user input, etc.. this is not for you. **What problems is Box2D solving and how is that benefiting you?** Box2d allows you to create impressive games or tech demos with interesting mechanics. It's a ton of fun to see images on the screen come to life and behave realistically. The performance is also better than many other 2D physics engines available. It has bindings for many different languages so you can use whatever language you are most comfortable with. The only downside for me is that there isn't an official javascript version to be used on the web (aside from a few 3rd party versions that may or may not be up to date with the official version. ### 11. Best 2D open source Physics Engine **Rating:** 5.0/5.0 stars **Reviewed by:** Arthur F. | Creative Technologist, Design, Mid-Market (51-1000 emp.) **Reviewed Date:** January 18, 2016 **What do you like best about Box2D?** Being open source is one of the best values in Box2D. If you ever need a 2D physics engine, there is probably a implementation of Box2D for you. Box2D is the base of almost every 2D game engine and it works very well without a game engine as well. It is very well developed and has an incredible performance even on high level implementations, such as on Processing. You might take a while to get adjusted into Box2D but after the initial setup you realize how powerful this engine is. You can basically develop anything that has any sort of physics, from top down shooters to platforms. This engine is so successful in doing what it was meant to do that even bigger engines like Unity used Box2D on the physics implementation. There is no doubt that Box2D excels on what it was made to do. **What do you dislike about Box2D?** If you are using Box2D without any other engine, it can take a while to understand and get everything working properly. It is an amazing engine but hard to master. As it is already 8 years old, it is not as modern as others engines around, but it definitely does the job better than any other. **Recommendations to others considering Box2D:** You can easily mess up Box2D with your rendering engine and have a very bad hierarchy. Take care of your organization and use Box2D only as a physics simulation. **What problems is Box2D solving and how is that benefiting you?** I've been developing small game engines and simple games. Box2D was my number one solution for 2D Physics for its performance. It is incredible how this engine can make so many collisions and interactions without consuming so much power. ## Box2D Discussions - [What is Box2D used for?](https://www.g2.com/discussions/what-is-box2d-used-for) - [View Box2D pricing details and edition comparison](https://www.g2.com/products/box2d/reviews?section=pricing&secure%5Bexpires_at%5D=2026-05-14+19%3A37%3A24+-0500&secure%5Bsession_id%5D=6fc4a768-776d-464d-87c6-ca10dfd647cb&secure%5Btoken%5D=2f58e354d9cfa361b68b0a1fcbd4fe0344bf5c29ffd4fc7f65406f00ec8937a5&format=llm_user) ## Top Box2D Alternatives - [PhysX](https://www.g2.com/products/physx/reviews) - 3.9/5.0 (37 reviews) - [Bullet](https://www.g2.com/products/bullet/reviews) - 4.0/5.0 (2 reviews) - [BeamNG](https://www.g2.com/products/beamng/reviews) - 4.5/5.0 (1 reviews)
