Aicss

AICSS is a library of copy and paste UI components for the interfaces of AI agents. It covers the elements an agent shows mid conversation: thinking and reasoning states, animated orbs, audio waves, tool and action states such as file diffs and image processing, text responses, streaming text, code blocks and inline citations, structured outputs such as to do lists, data tables and comparison tables, and interactive pieces including message actions, a reasoning effort control, an agent input box and approval cards. It is aimed at front end developers building chat and agent products who want polished agent specific UI without designing it from scratch. The catalog currently lists 17 components, several with multiple variants, and every component ships with ready code for React, Vue and Svelte. The copied snippets are self contained CSS, so they do not require Tailwind in the host project. After purchase, code is available on the site's Code tab and through a CLI and shadcn registry authenticated with an account token. Some components are free to use in personal and commercial projects without a license. The rest require a one time Pro license with lifetime access to every current and future component: Personal costs $89 once for a single developer, and Enterprise costs $299 once and covers entire teams and organizations. Both licenses allow commercial and client work, and neither is a subscription. Licenses grant usage rights only; redistributing or reselling the components as they are, for example in a competing template or component library, is not permitted, and because full source is delivered immediately, licenses are generally non refundable.
