Orvain UI vs shadcn/ui

shadcn/ui is the default answer for a React project that wants owned, Tailwind-styled components and nothing else to manage. Orvain is aimed at teams who also need the design file and the code to stay the same thing.

Where Orvain is today

Orvain's Figma library is finished and available. The code library and the MCP server are still being built, so anything below about generated code describes what is being shipped rather than something you can install today. Where that changes a comparison, it is said in the row.

What shadcn/ui is

shadcn/ui is a collection of accessible React components you copy into your own repository rather than install as a dependency. A CLI writes the source into your project, and from that moment the files are yours to edit — there is no package to upgrade and no abstraction between you and the markup.

It is free and MIT-licensed, styled with Tailwind, and built on top of established headless primitives. It is the most widely adopted approach of its kind by a considerable distance, which means an enormous amount of community work, examples and answers already exists around it.

The differences

	shadcn/ui	Orvain UI
How you get the code	A CLI copies component source into your repository. No runtime dependency, no upgrade path — the files are yours from the first minute.	The same idea: copied code you keep. The difference is what it is copied from, not what you end up owning.
Frameworks	React, officially. Ports to other frameworks exist and are maintained by the community rather than by the project.	React and Vue are both first-class targets, built from one shared contract rather than one being a translation of the other.
Design file	No official Figma library. Community kits exist and are not kept in step with the code by the project itself.	The Figma library is the part that exists today, and the props and token names are the same on both sides by construction rather than by discipline.
What an AI assistant reads	Whatever it absorbed during training, plus whatever you paste into the prompt. Very widely represented in training data, which helps — but it is still a snapshot.	A hosted MCP server is the plan: the assistant queries the real component surface instead of recalling it. Not live yet, so today this row favours shadcn/ui on availability and Orvain on approach.
Cost	Free, MIT.	A free component set plus paid tiers. If cost is the deciding factor, shadcn/ui wins it outright.
Maturity	Years of production use, an enormous community, and an answer to almost any question already written down somewhere.	New. The Figma library is finished; everything else is in progress. That is a real difference and it is not in our favour.

Which to choose

Choose shadcn/ui if

You are building in React and have no Figma file to keep in step with.
Cost matters more than anything else on this page.
You want the largest possible pool of existing examples, answers and community components.
You need it today, in production, with no unknowns.

Choose Orvain UI if

Designers and engineers are both working from one system and the drift between the file and the code is costing you real time.
You ship React and Vue and do not want two libraries that diverge.
You expect AI assistants to write against your components, and want them reading the real API rather than guessing.

Questions

Is Orvain UI a fork of shadcn/ui?

No. They share one idea — that you should end up owning the component source rather than depending on a package — because that idea is correct, and shadcn/ui is what popularised it. Everything else differs: the components are built independently, Vue is a first-class target rather than a community port, and the design file is maintained as part of the system rather than alongside it.

Can I use both in the same project?

Yes. Both give you plain source files in your own repository, so there is no dependency conflict to resolve and no runtime to reconcile. The practical cost of mixing them is stylistic: two sets of components mean two sets of naming and token conventions, and reconciling those tends to be more work than picking one.
