Polycam and OpenUI serve completely different needs. Polycam is a mature 3D scanning tool for creating digital twins and floor plans, ideal for AEC and media professionals. OpenUI is a developer-first generative UI framework for building token-efficient, streaming UIs powered by LLMs. Choose Polycam if you need reality capture; choose OpenUI if you want AI-generated interfaces for agents or dashboards.
OpenUI is an open-source framework that lets AI agents stream interactive UI from your own React, Vue, Svelte or React Native components instead of raw JSON.

Openui
39 mentions across 3 sources · 48% positive — mixed (averaged across 3 sources)
Hacker News, GitHub, Lemmy
What users praise
- • Up to 67% token savings versus JSON for UI generation.
- • Streaming-first architecture enables progressive UI rendering.
- • Supports all major LLMs and agent frameworks as drop-in.
- • Built-in component libraries (ShadCN, Material, DaisyUI).
What frustrates them
- • Frequent regressions break local model support (Ollama).
- • Blank page on Windows 11 and Docker in early versions.
- • Name clashes with W3C OpenUI, causing search confusion.
- • Installation fails on M1 Mac due to weave dependency.

Polycam
68 mentions across 5 sources · 42% positive — mixed (weighted across 5 sources)
Reddit, Hacker News, YouTube, Product Hunt, App Store
What users praise
- • Produces usable point clouds and meshes from a plain iPhone in a single site visit
- • Genuinely fast — users report scan-to-model turnaround in minutes, not days
- • Broad export coverage: seven mesh formats plus six point cloud formats
- • Fire investigators use it for measurements, 3D models, and Meta Quest walkthrough training
What frustrates them
- • Aggressive trial auto-billing: multiple users report $400/yr charges after 7-day trials
- • Long-standing Pro users report older scans reverting to unprocessable Draft status
- • Measurements and dimensions sit behind an expensive tier above the monthly plan
- • Floor plans described as poor and measurements 'very inaccurate' by paying users

Who should pick which
- Architect needing on-site floor plansPick: Polycam
Polycam's automatic floor plan generation with measurements and LiDAR scanning is ideal for capturing interior spaces and producing accurate digital floor plans.
- Developer building AI agent with dynamic UIPick: Openui
OpenUI's token-efficient OpenUI Lang and streaming-first rendering create interactive UIs for AI agents, replacing static chat responses with dashboards and forms.
- Forensics team documenting crime scenesPick: Polycam
Fast LiDAR scanning, photogrammetry, and the ability to export point clouds create precise 3D documentation for evidence.
- Full-stack engineer prototyping generative UIPick: Openui
OpenUI's cross-platform support and custom component libraries allow rapid prototyping of AI-generated interfaces without reinventing UI generation.
- Product designer scanning physical prototypesPick: Polycam
Polycam's photogrammetry from photos and video captures detailed 3D models of objects for digital review and export to CAD tools.
Frequently Asked Questions
Openui vs Polycam: which should you choose?
Polycam and OpenUI serve completely different needs. Polycam is a mature 3D scanning tool for creating digital twins and floor plans, ideal for AEC and media professionals. OpenUI is a developer-first generative UI framework for building token-efficient, streaming UIs powered by LLMs. Choose Polycam if you need reality capture; choose OpenUI if you want AI-generated interfaces for agents or dashboards.
Can Polycam generate 3D models from photos alone?
Yes, Polycam offers AI-assisted photogrammetry from photos and video. You can upload images, and it processes them into 3D models.
Is OpenUI free to use?
Yes, OpenUI is open-source and free for self-hosting. OpenUI Cloud offers paid tiers with additional features like editable artifact generation.
Does Polycam support Windows?
Polycam is primarily for iOS and Android devices, but the web interface allows viewing and editing captures. There is no dedicated Windows app for scanning.
What programming languages does OpenUI support?
OpenUI is a framework for JavaScript/TypeScript. It renders UI in React, React Native, and Vue.
Can OpenUI work with any LLM?
OpenUI supports all major LLMs: OpenAI, Anthropic, Gemini, Mistral, xAI, DeepSeek, and can integrate with agent frameworks like Vercel AI SDK and LangChain.
Does Polycam export to CAD formats?
Polycam exports to multiple formats including OBJ, FBX, GLTF, USDZ, STL, DXF, and point cloud formats. DXF is a CAD-compatible format.
What is OpenUI Lang?
OpenUI Lang is a compact, line-oriented language designed to represent UI components. It is up to 67% more token-efficient than JSON, reducing LLM cost and latency.
Can both tools be used for real-time applications?
Polycam captures are processed asynchronously (not real-time scanning). OpenUI supports streaming-first rendering, making it suitable for real-time AI UI generation.
