AICSS
14 copy-paste agent-chat components in React, Vue and Svelte with plain CSS, 9 free
AICSS is a small collection of UI blocks for the things an AI agent shows mid-conversation: thinking states, tool calls, streaming text, citations, code blocks, to-do lists and data tables. It ships 14 components in five groups — Thinking & Reasoning (3), Tool & Action States (3), Text Outputs (4), Structured Outputs (3) and Rich & Interactive (1) — each with a live light/dark preview and a Code tab that toggles between React, Vue and Svelte. There is no Tailwind dependency: components are framework-native code plus CSS Modules. Nine components are free; the other five unlock with a one-time license, and you must sign in to copy the code. Currently labelled Beta V1.2 and built by a solo developer (@kvnkld).
Reach for AICSS over Vercel AI Elements only when the project is Vue or Svelte, or when the codebase has no Tailwind and you want CSS Modules instead — that is its real differentiator, since AI Elements is React-plus-Tailwind only. Do not plan an install step: there is no npm package, no CLI and no shadcn registry, so the flow is a human signing in and copying source out of the Code tab, and five of the fourteen components are behind a $190 paywall you cannot reach. Treat the component set as a spec you can reimplement rather than a dependency, and check accessibility yourself — nothing here claims ARIA or keyboard coverage.
Why it is here. It is one of the few agent-chat component sets that is not React-and-Tailwind, which makes it the fallback when a Vue or Svelte app needs credible thinking, tool-call and streaming UI.
