Welcome to the Bldrs GitHub organization.

We’re building open, browser-native tools that let engineers, designers, and builders collaborate with AI around CAD engineering models with the same ease and intelligence that modern software teams enjoy.

Share is a browser-based collaboration environment for sharing and exploring CAD engineering models.

• Instant share links for IFC and STEP
• Real-time navigation with your team
• Federated versioning inspired by modern software workflows
• No installs, no friction

We’re approaching v1.0 with our first full MVP and preparing the rollout of our Pro offering.

Conway is a high-performance, WebAssembly-powered 3D engine optimized for engineering workflows. This is the IFC/STEP engine behind Share.

Loads complex IFC, STEP, and open-standard models directly in the browser

• Fast, local execution for privacy and speed
• Lightweight, extensible, and open to integration
• This is the technical foundation for real-time collaboration and AI-driven model understanding.

We’re designing an AI that participates like a teammate rather than a tool.

That includes:

• answering model questions
• generating views, analyses, and checks
• helping teams explore alternatives
• translating natural language into engineering actions
• automating repetitive review workflows

Our vision is a design ecosystem where humans, AI, and open standards all collaborate in the same shared space.

We believe engineering workflows should evolve the way software development has:

• open standards
• transparent versioning
• lightweight collaboration
• automation and AI assistance
• portable, browser-first tools

GitHub is the natural home for these ideas, and our repos reflect our commitment to an open, interoperable future for engineering.

We welcome:

• issues and feature requests
• integrations with IFC/STEP workflows
• community discussions
• contributions that push open engineering forward
