UI Discovery verdict
UI Discovery is the right pick for product designers and vibe-coders who want real, shipped interfaces rather than curated mockups, especially when they are already working inside Cursor, Claude, or ChatGPT via MCP. Its library skews heavily toward iOS apps (3,836 entries) and marketing sites, so web-app and dashboard coverage is thin compared to what a dedicated component library offers. Teams expecting shared workspaces or member invitations should look elsewhere; those features are explicitly not available yet.
Strengths
MCP connector is free on every plan and works with ChatGPT, Claude, Cursor, and Codex, letting AI editors query 111,083 real sections mid-session without leaving the editor.
Free tier is genuinely usable: full catalog browsing, palette and font data for every site, and 200 API requests per day with no credit card required.
Weaknesses
Web app and dashboard coverage is sparse: only 62 web-app UIs and 42 admin dashboards in the entire library, which makes it a poor reference source if your project is a data-heavy product UI rather than a marketing site or iOS app.
The Team plan at $39/month includes one account and a higher API limit but no shared workspaces, member invitations, or comments, making the tier name misleading for anyone expecting actual team collaboration.
FrameThrower verdict
FrameThrower works best for filmmakers, advertising creatives, and AI developers who need richly tagged film-still references and flexible integration via API or MCP. It delivers deep metadata, depth maps, and composable prompts, but it does not license images and forbids AI ingestion of frames, which may limit reuse. If you need licensed assets or broader design features, consider Canva instead.
Strengths
Rich metadata and depth maps included with every frame at no extra cost
Multiple integration options. REST API, MCP server, npm SDK, ComfyUI node
Weaknesses
Frames are reference-only; no licensing or rights clearance provided
Credit-based API/MCP usage adds complexity and cost tracking
