Until now, making geometry on Bitbybit meant writing it: wiring nodes in Rete, snapping blocks in Blockly or typing TypeScript. Those editors shine when a model is a program, a family of parts generated from a few numbers. But a lot of design isn't programming. You want to draw a profile, pull it into a solid, round an edge, drill four holes and see the result straight away.

The Designer is our answer: a parametric CAD modeller you use with the mouse, in your browser. Draw a sketch, extrude it, fillet it, drill it, then put parts together with joints and pose the assembly. Every step is kept, so changing a size later rebuilds everything that depends on it. The Bitbybit OCCT Kernel does the modelling on your own machine, so there is nothing to install. And because the Designer was built for AI agents as much as for people, an agent can work in the same document beside you, while you keep or undo each of its changes.

Bitbybit has three coding editors: Rete, where you wire nodes together; Blockly, where you snap blocks; and TypeScript, where you write code against the same API. This release rebuilds a large part of all three. Most of the work went into Rete, which now stays readable when a script grows to hundreds of nodes. Blockly functions can await geometry, TypeScript scripts can span many files, and an AI agent can drive any of the three editors.

To show what that adds up to, we built one drone in all three editors: a quadcopter with a carbon frame, motors with cooling slots, propellers that alternate their spin, a canopy traced with a honeycomb and the bitbybit logo on its hatch, sprung landing legs and a camera on a gimbal. Each build is a tutorial with a picture after every step.

More and more of the code that uses Bitbybit is not typed by a person. It is written by an AI coding agent, inside an editor or a terminal, while a person describes what they want and judges what comes back. We think this is where 3D development is heading, and we want Bitbybit to be the CAD library that agents get right. That is why Bitbybit now runs its own MCP servers: one that teaches any agent the exact Bitbybit API, and one that lets an agent run real CAD operations for you.

To show what that looks like in practice, we asked an agent to build something far beyond a demo cube: a two-spool turbofan engine with 130 unique parts placed 4,853 times, bolted flanges, blades seated in slotted disks, a casing that opens, an exploded view and a welded transport stand. This post explains what MCP is, the use cases we care about most, what they mean for you, and how the engine was made.

Some companies pick a name and then have to live up to it. Gamechanger Furniture builds gaming chairs by hand in northern Germany, and when they decided that every customer should design their own chair - the fabric, the colours, the stitching, their initials embroidered on the headrest, even their own logo - they needed a product page that could keep up with the name. What they launched is, quite literally, a game changer for how a chair gets sold: shoppers put it together in 3D, watch the price follow every choice, see their name appear on the chair, and take a PDF of their design away with them. All of it was built inside the 3D Bits app for Shopify, without a single line of code.

In April 2026 Bitbybit travelled to Hannover, where Matas Ubarevičius delivered the presentation titled "The Browser Is the New CAD: From Code to Configurable Products" at Hannover Messe, the world's leading trade fair for the manufacturing industry. The talk was accepted by CAE-Forum for their curated presentation stage and featured in their newsletter. In this blog post he shares his experience from the event and explains why this discourse matters for the manufacturing industry today.

After nearly 100 releases in the 0.x.x range and a release candidate phase, Bitbybit v1.0.0 is officially here. This release brings our new CAD foundation, cloud infrastructure, and an expanded toolkit for developers.

This post outlines the major architectural changes and new capabilities available across our NPM packages, TypeScript SDK, Bitbybit Studio, and the Managed CAD Cloud.

Demand for customizable products that don't need to be redesigned from scratch for every unique customer or situation is growing across the manufacturing industry. STOCKMHS recognized this early and created the modular EZ~FLO 2.0 Chute System (Patent Pending), which gives their team the freedom to adapt a proven product to any situation. Through our collaboration, we built a browser-based 3D configurator that serves as a digital twin for the entire spiral chute product line - letting the sales and engineering teams explore configurations, generate bills of materials, and produce branded PDF reports without ever leaving their browser.

How do you sell a modular power rack online when every customer wants a different combination of uprights, crossbars, pull-up bars, and accessories - and needs to see the result before committing? Strength Shop answered that question by building a fully interactive 3D configurator powered by 3D Bits, with a completely custom user interface designed and developed by their own team.

How do you let customers design their own precision-cut metal parts online - with exact dimensions, real manufacturing constraints, and instant visual feedback? That was the challenge facing The Shim Shack. Through our collaboration, we delivered a suite of parametric 3D configurators that run directly inside their existing WordPress store. You can try them yourself at buildyourparts.theshimshack.com.

Bitbybit is heading to Hannover Messe 2026. On April 24, founder Matas Ubarevičius will be giving a 30-minute presentation titled:

The Browser Is the New CAD: From Code to Configurable Products

Here is what the talk will cover and why it matters.
