Bit by bit developers has always championed the democratization of CAD. The platform empowers users to run complex 3D algorithms directly in the browser - zero installation, zero friction. But as customer ambitions grow, so must the infrastructure.

Today marks the next evolution of the Bitbybit ecosystem: Managed Bitbybit CAD Cloud, powered by a RESTful API.

This is a fundamental expansion designed for enterprise B2B customers who demand more compute power, better IP protection, and scalable workflows than a browser-only environment can provide.

If you've ever tried to load, edit or create a complex STEP assembly in a web browser, you know how tricky it can be. STEP is the standard format engineers use to share CAD models, but browsers don't understand it natively. You usually need desktop software or a server to convert it.

With Bitbybit v1.0.0-rc.1, that changes. You can now load STEP assemblies directly in the browser, explore their structure, extract individual parts, and export to web-friendly formats. Everything runs locally using Bitbybit OCCT WebAssembly.

After nearly 100 releases in the 0.x.x range, version 1.0.0 Release Candidate 0 is now available. This is a huge milestone for Bitbybit and represents extensive engineering work to set the project on a solid foundation for years to come.

Modern AI assistants like Claude, Gemini, Grok or ChatGPT or are remarkably capable at writing code. However, they can struggle with specialized libraries and APIs they weren't extensively trained on. That's where AI Prompt Contexts come in - specially crafted documentation files that give your AI assistant deep knowledge of the Bitbybit API.

Bitbybit brings a brand new developer experience to the table. Say hello to @bitbybit-dev/create-app, a CLI tool that lets you scaffold fully-configured 3D CAD projects in just a few seconds.

We are excited to announce the release of our new open-source NPM package and runner for PlayCanvas, one of the most performant and feature-rich WebGL game engines available. The @bitbybit-dev/playcanvas package and PlayCanvas Runner continue our mission to make professional 3D CAD accessible across the entire web development ecosystem, now empowering PlayCanvas developers with industrial-grade geometric modeling capabilities.

How do you sell a modular gym rack with over 60+ customizable parts online? Static images don't cut it. Videos can only show so much. And asking customers to imagine how different components fit together? That's a recipe for confusion and abandoned carts.

Ironside Armour, a global fitness equipment company, faced exactly this challenge. Through close collaboration with our team, they developed interactive 3D configurators powered by 3D Bits - a rewarding journey that transformed how their customers shop.

In our ongoing mission to make powerful 3D design tools accessible to everyone, we're thrilled to announce a significant milestone: all components of Bitbybit.dev's Rete and Blockly visual programming editors are now translated into multiple new languages!

We are happy to announce that the 3D Bits app for Shopify has been updated with some powerful new capabilities designed to simplify common use cases! While parametric 3D models offer incredible flexibility, we understand that the learning curve associated with programming them can be steep.

Our Bitbybit Runners allow you to easily include Bitbybit.dev's powerful 3D CAD and computational geometry capabilities into your own websites via a single UMD JavaScript file. In our latest release, we're excited to introduce a completely new runner specifically for the ThreeJS game engine!
