Our verdict on Physion
Physion is a browser-based 2D physics simulator for teachers, students, hobbyists, and classroom demonstrations. It lets users draw shapes, connect them with joints, springs, ropes, and motors, adjust physical properties, and run simulations in real time. The feature set includes rigid-body, liquid, soft-body, and particle simulation, along with JavaScript Node Scripts, Boolean shape operations, laser raycasts, live graphs, live free-body diagrams, and scene publishing. It runs in a desktop browser without installation, while phones and tablets can view and interact with existing scenes but cannot create new ones.
The pricing structure keeps the core simulation tools on the Free plan, which includes every simulation tool and link-based scene publishing, with ads. Basic costs $6 per month or $60 per year and adds an ad-free experience while retaining everything in Free. Pro costs $10 per month or $100 per year and adds premium support to the Basic features. This makes Physion a straightforward fit for learners, educators, and hobbyists who want 2D authoring without a higher subscription commitment. The Free plan suits casual use; Basic is the practical choice for users who want to remove ads; Pro is aimed at those who value premium support.
Physion’s standout strength is the range of visual and interactive elements available within a 2D workspace. Users can combine physical bodies with springs, ropes, motors, liquids, particles, raycasts, scripts, graphs, and free-body diagrams, then publish scenes for link sharing. That breadth supports experiments and demonstrations rather than only basic rigid-body examples. The trade-off is a narrow delivery model: authoring is desktop-browser based, with no offline access or 3D visuals. Choose Physion for affordable browser-based 2D model creation and sharing; choose an alternative if mobile authoring, offline work, or three-dimensional scenes are central requirements.
