AI-built SolidCraft takes aim at Fusion 360’s cloud lock-in

A new open-source, locally run CAD project is challenging Autodesk’s subscription and cloud-first model, although it remains an early-stage work in progress.

The emergence of SolidCraft has added a new angle to the debate over proprietary design software, with the project presented as a clean-room, open-source recreation of Autodesk Fusion 360 built with AI assistance. According to Fabbaloo, it is freely available, runs locally and is intended to provide tools for sketching, modelling and assemblies without requiring a cloud account or subscription. For users who have grown frustrated with the cost and online dependence of mainstream CAD platforms, that combination is likely to be the project’s main appeal.

The enthusiasm around SolidCraft also reflects a wider backlash against software vendors that many users see as increasingly restrictive. In the source article, the author compares Adobe’s subscription model with Autodesk’s pricing and cloud-first approach, arguing that both can leave customers feeling trapped once they have built their workflows around them. That frustration is not limited to design software. It also sits within a broader argument about how much control users should retain over their tools, data and working environment, especially when companies are leaning more heavily on subscriptions and online services.

Fabbaloo says SolidCraft has already attracted attention in the 3D printing community since appearing on GitHub about two weeks ago. The project is described as a clean-room reimplementation, which matters because it suggests the software is meant to mimic Fusion 360’s behaviour without copying proprietary code. That distinction may help the project avoid some of the legal and technical pitfalls that have followed other software clones, while also making it more credible to users who want an alternative rather than a simple imitation.

Even so, the project appears to be early in its life cycle. The source material notes that SolidCraft still needs work and fixes, despite its promise as a locally run alternative to cloud-based CAD. That is an important caveat for anyone considering it as a production tool. For now, the software seems to represent more of a proof of concept than a mature replacement, but it points to a growing willingness among developers to use AI tools to challenge established software monopolies rather than reinforce them.
