Two different bets
Tailwind Plus — the product formerly sold as Tailwind UI — is a commercial, first-party catalogue of professionally designed, copy-paste markup from the team behind Tailwind CSS itself. You buy a license, browse 500+ UI blocks, full site templates and the Catalyst React kit, and paste the markup straight into your project. The design quality is high and unmistakably on-brand for Tailwind, which is exactly what you're paying for.
It's important to be precise about what Tailwind Plus is and isn't: it is not a runtime component library. There's no package you import and upgrade, no versioned API. It's markup you own the moment you paste it, with interactivity supplied by Headless UI for the parts that need behaviour (menus, dialogs, comboboxes). The upside is total ownership and no dependency; the downside is that every pasted block is markup you now maintain by hand, and fixes or new designs don't reach an existing screen automatically.
Vireya takes the opposite shape. It's a free, source-available, versioned package — `@vireya/*` with per-component subpaths — of real components, blocks and a charts library, themed through a `createTheme()` engine and styled with static CSS Modules driven by `--v-*` tokens. There's no Tailwind in the stack and no markup to re-paste: improvements arrive the way any dependency upgrade does, and one token layer re-themes components, blocks and charts together.
The honest framing is markup-you-buy-and-own versus a-package-you-install-and-upgrade. If you're already all-in on Tailwind and want the highest-polish ready-made designs to own outright, Tailwind Plus is a strong, well-supported product. If you'd rather have a free, maintained component library with real charts and a path to ship the same UI as a hybrid mobile app, Vireya is the different model — accepting that it's early (v0.1.0) and not a 500-block catalogue.
Under the hood
A paid copy-paste markup model, not a runtime library
Tailwind Plus sells access to designs, not a dependency. You purchase a license, copy the Tailwind-class markup for a block, and it becomes part of your source. There is no version number to track and no `import` to upgrade — what you pasted is frozen until you manually replace it. Maintenance and divergence are entirely on you, per project, per block.
Vireya is distributed as a versioned npm package with per-component subpaths, so you bundle only what you import and you upgrade the whole system at once. You trade source ownership for centralised, versioned maintenance — fixes and new components arrive through `pnpm upgrade` rather than a return trip to the catalogue.
Interactivity via Headless UI vs built-in behaviour
Tailwind Plus markup is static by itself; the interactive pieces lean on Headless UI, the team's separate unstyled-behaviour library, which you install and wire up. The styling is yours (Tailwind classes), the behaviour comes from a second package, and the integration is your responsibility.
Vireya ships components with behaviour already built in, accessible by virtue of building on Radix and base-ui primitives. A dialog or a combobox is one import with its keyboard handling, focus management and ARIA already in place — there's no separate behaviour library to bolt onto pasted markup.
Styling: Tailwind classes vs tokenized CSS Modules
Every Tailwind Plus block is expressed as Tailwind utility classes, so re-theming means editing class strings across the markup you pasted, or reaching into your Tailwind config. The design lives in those classes, distributed throughout your source.
Vireya ships static CSS Modules whose every value resolves to a `--v-*` token, with no Tailwind dependency and no runtime CSS-in-JS. You re-theme by changing token values once through createTheme(), and components, blocks and charts all follow — including light/dark and tier-based palettes.
Reaching mobile: web-only vs hybrid delivery
Tailwind Plus is a catalogue of web markup. Its templates and blocks render in the browser; shipping a mobile app from them means a separate effort — a React Native rebuild or your own native wrapper — because the markup has no delivery path off the web.
Vireya is built around hybrid delivery. You build and theme the UI once as a web app, then run it inside a native WebView shell with a typed RPC bridge (`@vireya/rpc`) that exposes native functions — payments, sensors, push — to the web layer. It's the Mobile Bridge pattern Shopify documented and that commerce apps like Mercado Livre and Magazine Luiza ship, so the same screens reach mobile without being rebuilt in React Native. The bridge is still maturing (Expo first), so treat it as the model Vireya is built around rather than a turnkey feature.

Where Tailwind Plus (Tailwind UI) shines
- A large, professionally designed catalogue — 500+ responsive blocks plus full marketing and application templates — at a level of polish that's genuinely hard to match by hand.
- First-party provenance: it's made by the Tailwind CSS team, so it tracks the latest Tailwind features and conventions closely.
- One-time lifetime pricing that includes future additions to the catalogue, rather than a recurring subscription.
- Multiple output formats — React, Vue and plain HTML variants, the Catalyst React UI kit and Next.js templates — so it slots into most stacks.
What Vireya does differently
- Vireya is free and source-available and distributed as a versioned package, so fixes and new components arrive through upgrades instead of a return trip to a paid catalogue to re-paste markup.
- Styling is static CSS Modules driven by `--v-*` tokens with no Tailwind dependency, where Tailwind Plus is Tailwind markup you edit class-by-class.
- A real, tokenized charts library is bundled; Tailwind Plus is markup blocks and templates with no charting at all.
- Behaviour is built into Vireya's components on Radix and base-ui primitives, rather than coming from a separate Headless UI install you wire into pasted markup.
- Vireya is built for hybrid delivery — the same web UI ships as a native mobile app through a WebView shell and a typed bridge — where Tailwind Plus is web markup that stops at the browser.
When to choose Tailwind Plus (Tailwind UI)
- You're already committed to Tailwind and want the highest-polish ready-made marketing and application markup.
- You want a large catalogue of designs to copy and own outright, with no runtime dependency.
- You're comfortable maintaining the pasted markup by hand and wiring up Headless UI for interactive parts.
- You value first-party Tailwind provenance and lifetime access to a growing design catalogue.
When to choose Vireya
- You want a free, maintained component package instead of a paid copy-paste markup catalogue.
- You'd rather theme through `--v-*` tokens than edit Tailwind classes across pasted blocks.
- You need real components and a charts library, not static markup you assemble and animate yourself.
- You want a path to ship the same UI as a hybrid mobile app and want accessible behaviour built in rather than bolted on.
Switching from Tailwind Plus (Tailwind UI) to Vireya
Moving from Tailwind Plus to Vireya means trading pasted markup for imported components. Where you previously copied a block and maintained its Tailwind classes, you import a Vireya component or block and theme it through tokens. The interactive pieces you wired up with Headless UI are replaced by Vireya's built-in behaviour, so that integration code can usually be deleted rather than ported.
The main planning consideration is design fidelity: Tailwind Plus blocks are bespoke markup, so a screen-by-screen migration is the realistic path — rebuild a section with Vireya components and tokens, confirm it matches, then remove the old markup. Because Vireya carries no Tailwind dependency, you can also retire Tailwind from migrated areas entirely once nothing left depends on its classes.
The bottom line
Tailwind Plus and Vireya answer different questions. Tailwind Plus sells you beautiful, first-party Tailwind markup to own and maintain forever — if you live in Tailwind and want a deep catalogue of polished designs, it's worth the license and hard to fault on craft. Vireya is a free, versioned component library with built-in behaviour, a token engine, bundled charts and a path to ship the same UI as a hybrid mobile app, where improvements arrive through upgrades rather than re-pasting. Choose Tailwind Plus for the catalogue and the ownership; choose Vireya for a maintained, tokenized system — provided you're comfortable with a younger, smaller project.

Frequently asked questions
Is Vireya a Tailwind UI / Tailwind Plus alternative?
Yes, for teams who want a free, versioned component package instead of paid copy-paste Tailwind markup. Vireya bundles tokenized components, blocks and a charts library you upgrade like any dependency, with built-in behaviour and no Tailwind requirement, where Tailwind Plus is markup you buy and maintain by hand.
Is Vireya free? Tailwind Plus is paid.
Vireya is free and source-available — every component, block and chart is included with no feature paywall. Tailwind Plus is a commercial product with a one-time license. With Vireya you install a package and upgrade it; with Tailwind Plus you buy access and paste markup that you then own and maintain yourself.
Is Tailwind Plus a component library like Vireya?
Not in the same sense. Tailwind Plus is copy-paste markup with no runtime package — interactivity comes from a separate Headless UI install. Vireya is an actual versioned component library: you import components whose behaviour and accessibility are already built in on Radix and base-ui.
Does Vireya use Tailwind?
No. Tailwind Plus is Tailwind markup. Vireya ships static CSS Modules driven by --v-* tokens, with no Tailwind dependency and no runtime CSS-in-JS — you theme by changing token values through createTheme().
Does Vireya include charts, and can it reach mobile?
Yes to both. Vireya bundles a tokenized charts library sharing the components' tokens. For mobile it's built around hybrid delivery: the same web UI runs inside a native WebView shell with a typed bridge (`@vireya/rpc`) for native functions — the Mobile Bridge pattern Shopify documented and apps like Mercado Livre and Magazine Luiza use — so you reach mobile without a React Native rebuild. Tailwind Plus is web markup with no charting and no native delivery path; the bridge is maturing, Expo first.
Which should I choose?
Choose Tailwind Plus if you're all-in on Tailwind and want a large catalogue of polished markup to own outright. Choose Vireya if you want a free, maintained component library with built-in behaviour, a token engine, bundled charts and a path to ship the same UI as a hybrid mobile app, where fixes arrive through upgrades rather than re-pasting.
