Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pick-ui-library scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Guide for Selecting a UI Component Library

Choosing the right UI library is a crucial architectural decision that impacts development speed, application performance, and long-term maintainability. This guide covers how to evaluate and select the best UI library or styling solution for your project.

1. Evaluation Criteria

When comparing libraries, consider the following technical and operational factors:

Criterion What to Evaluate Why it Matters
Bundle Size & Tree-shaking Does it support ES modules? Can you import individual components? Impacts initial load time and overall app performance.
Accessibility (a11y) Does it follow WAI-ARIA guidelines? Are components keyboard navigable? Ensures legal compliance and usability for all users.
Theming & Customization How easy is it to override default styles? Does it support dark mode? Determines if you can match your brand identity without fighting the framework.
TypeScript Support Are types included or maintained via DefinitelyTyped? Are they strict? Enhances developer experience, auto-completion, and bug prevention.
Community & Maintenance Look at GitHub stars, open issues, release frequency, and ecosystem. Indicates longevity and likelihood of finding solutions to obscure bugs.

2. React UI Libraries Comparison

Library Paradigm Pros Cons Best For
shadcn/ui Copy-paste components (not a dependency) Full control, Tailwind native, high quality Requires manual updates, boilerplate in your repo Modern SaaS, custom designs, team with strong React/Tailwind skills
MUI (Material-UI) Full UI Framework Massive ecosystem, highly featured, robust Large bundle size, Material design look is hard to shake Enterprise apps, internal tools, rapid prototyping
Radix UI Unstyled primitives Perfect accessibility, bring your own styles Steep learning curve for styling from scratch Design systems, highly custom UIs
Chakra UI Styled components with utility props Excellent developer experience, accessible Runtime CSS-in-JS overhead Startups, fast-moving teams wanting good defaults
Mantine Full UI Framework Huge amount of hooks/components, fully featured Custom styling approach, learning curve Feature-rich web apps, dashboards
Ant Design Full UI Framework Comprehensive, great for data-heavy apps Large bundle, opinionated design, localization hurdles Complex enterprise admin panels
