shadcnblocks alternative, compared
sources read 18 August 2026shadcnblocks sells the largest blocks library in this comparison and it already works through the shadcn MCP server, so it is a genuinely agent-friendly purchase. Buy it if you build pages out of blocks. TailThemes is the alternative when you want whole sites instead of blocks, a framework-free HTML edition, and a price under a hundred dollars for the one thing you are launching.

| What one payment buysOne item, or the shelf? | Blocks and components at every tier. Templates, Figma kit and admin kit from $299. Pre-built pages and the page builder at $399.[1] | One template, in unlimited projects including client work, with 12 months of updates. |
| Catalogue sizeHow much is in there? | 2,093+ components, 1,678+ blocks, 19 templates, 49+ pre-built pages.[1] | 13 complete site templates. 11 paid, 2 free. |
| Editions per itemCan you use it without React? | shadcn/ui, React, Next.js, Astro and Figma, as listed on the pricing page. No framework-free HTML edition listed.[1] | React and Next.js, plus a framework-free HTML edition. Both in every zip. |
| Light and darkDo you get both, on everything? | not publishedNot stated on the pricing page.[1] | Both, on every template. Light-only is not a shipping option here. |
| Contrast evidenceHas anyone checked the colours against WCAG? | not publishedNo contrast testing published on the pricing or licence pages.[1] | Every foreground and background pair is computed against WCAG AA in both modes and recorded before a version ships. Computed, not eyeballed. |
| Agent toolingCan your coding agent find and install it? | Reachable through the shadcn MCP server: "Ask your AI assistant to browse and install blocks with natural language."[1] | An MCP server, a shadcn-compatible registry at /r/<slug>.json, and an AGENTS.md in every zip. |
| Client work and resaleWhat are you allowed to build with it? | Unlimited end products for yourself, your company or clients. You may sell end products where the components are not the primary value. No reselling components, no publishing them, no training AI generators on them.[2] | Unlimited projects, client work included. No reselling or redistributing the source, and no using it as model training data. |
| Updates and supportWhat happens after you buy? | Lifetime access and updates on every tier.[1] | 12 months of updates per template. Every version you bought stays downloadable forever. |
| RefundsWhat if it is wrong for you? | not verifiedNot stated on the pricing or licence pages we read. | 14 days, no questions asked. |
shadcnblocks reaching agents through the shadcn MCP server rather than its own is worth noting: the shadcn registry format is becoming the distribution channel for paid UI, which is the same bet we made with /r/<slug>.json.
Every template, twice: React and plain HTML
Every one of our 13 templates ships a Next.js and React project and a framework-free HTML build in the same zip. Hand the HTML to a client on any stack, or open the React project and keep going. No other product in this comparison ships both editions of the same design.

Which one to buy
- You build with shadcn/ui already and you want the blocks that match it.
- You want volume. Nothing else in this comparison is close on block count.
- You want a Figma kit and a page builder alongside the code.
- You want a finished site. Blocks are the assembly job we have already done.
- You need HTML with no React and no build step.
- You are buying one template, not a library. Ours start at $14; their entry tier is $149.
- You want the contrast computed and both modes guaranteed rather than inherited from the base library.
Where these numbers come from
Every competitor figure above was read from the vendor’s own page on the date beside it. Nothing is estimated. Where a vendor does not publish something, the table says so instead of guessing.
