Open Source 3D Printing Software

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

Manyfold is an open-source 3D collaboration platform that reimagines how distributed teams and communities can meet, create, and interact in immersive spatial environments through the web. Instead of forcing users to download native apps or create accounts on closed metaverse services, Manyfold runs entirely in the browser, letting people join 3D spaces with simple links and participate in real time using avatars, voice chat, and object interaction. Users can build or import shared 3D worlds, arrange media, embed content, and design interactive layouts that support presentations, workshops, social events, games, and team gatherings without heavy software installations. The platform emphasizes accessibility and flexibility, making 3D collaboration as easy as sharing a document link while still providing spatial audio, synchronized interactions, and physics-aware environments that feel alive and responsive.

AlohaMini is a lightweight self-hostable productivity and note-taking platform designed to help individuals organize thoughts, tasks, and knowledge in a fast, minimal interface that avoids unnecessary complexity. It combines hierarchical notebooks, rich text editing, and tagging, allowing users to structure information the way they think and refine that structure over time. The platform focuses on speed and responsiveness, with a UI that loads instantly and feels smooth even on modest hardware, making it ideal for both desktop and small server deployments. AlohaMini also supports internal linking between notes, enabling a web-like connected knowledge space that grows organically as users create and connect ideas. Collaboration features are integrated so teams can share notebooks, leave comments, and work simultaneously on a shared knowledge base without leaving the platform.
