3D Viewer Online
GeometryViewer is a free browser-based 3D model viewer and file sharing platform. No software installation required - everything runs directly in your browser using WebGL and Three.js technology.
Supported 3D file formats: STL, OBJ, GLB, GLTF, 3MF, and FBX. Upload any 3D model and instantly get a shareable link that works on any device, desktop, tablet, or mobile.
Key features:
Who uses GeometryViewer:
3D printing enthusiasts sharing models from Thingiverse, Printables, and MyMiniFactory without requiring viewers to install software. Product designers previewing models for clients. Teachers embedding 3D objects in educational presentations. Shopify and WooCommerce developers adding interactive product visualization. Engineers sharing CAD exports for remote review and approval.
GeometryViewer is the free browser alternative to Microsoft 3D Viewer (discontinued July 2026), Sketchfab Basic, ViewSTL, and other online 3D model viewers. It loads instantly, requires no account, and runs on every modern browser including Chrome, Firefox, Safari, and Edge. Also available as an Android app on Google Play. Supports offline use, embeds into any HTML page, and delivers a fast WebGL render on all modern devices.
PythonAnywhere
GeometryViewerPythonAnywhere is especially recommended for Python developers (beginners and intermediates), educators, students, and hobbyists who are looking for an easy and quick way to deploy and host their Python applications or who need an online python environment for coding practice.

GeometryViewer's answer:
Most 3D viewers make you install software, create an account, or pay for a subscription before you can even open a file. GeometryViewer does none of that. You drag a file in, you get a shareable link, and anyone with that link can view it in their browser, see it in AR on their phone, or export it as a GIF.
GeometryViewer's answer:
Because it is genuinely free with no catch. No account, no watermark on the free tier, no file size limit hidden behind a paywall, no install. Sketchfab requires an account and puts branding on free embeds. Most desktop viewers only work on Windows. Browser-based alternatives tend to support only one or two formats. GeometryViewer handles STL, OBJ, GLB, GLTF, 3MF, and FBX in one place, with AR preview on mobile and GIF export built in. It also works offline after the first visit.

GeometryViewer's answer:
Three.js for WebGL rendering, WebXR for augmented reality on mobile, and a custom Web Component that makes the viewer embeddable on any page with a single HTML tag. The PWA is built on standard Service Worker APIs for offline support. The backend is minimal - file storage and short URL generation. No server-side rendering of 3D content; everything runs in the browser.
GeometryViewer's answer:
It all started because sharing a 3D model with someone who has no 3D software is surprisingly painful. Sending a file means the other person needs software. Sketchfab requires an account. Microsoft 3D Viewer only works on Windows and is being discontinued in July 2026. GeometryViewer exists to solve that exact problem - open any common 3D format in a browser, get a link, share it. AR preview and GIF export came later as features users actually asked for.

The website is already built. Each comment will have a reddit post URL, and the bot should leave a comment on that URL. We can use pythonanywhere.com for this to make it easiest. Source: about 3 years ago
If you are learning, use pythonanywhere.com as they specialize in python, and make setup easy. Only $5 a month. Start with a barebones flask app, get it to run, then follow a tutorial. Actually better to build the app locally, easier to test with IDE like Pycharm. Then upload to the net. Source: about 3 years ago
Hello, I have a Minecraft server running on a Rpi with Paper. It works great and I use it to play with some of my friends. However, the server's public IP address often changes, meaning that I have to give my friends the new IP address daily. Being a programmer, I feel this could be automated. I don't want to buy a domain, so I want to try and setup a system where the server sends Its IP to my PythonAnywhere... Source: over 3 years ago
Hosting wise, I would reccomend pythonanywhere.com, combined with either https://imagekit.io or https://cloudinary.com. Source: over 3 years ago
So what is the best alternative? I have one Plotly Dash app on pythonanywhere.com where I spend 6 bucks a month so I don't want to spend anymore than 5 dollars per month on the PHP + MySQL. Source: over 3 years ago
