Browsing and searching the marketplace is free. 21st AI generation runs on credits available with Builder or Team when AI is enabled. Both plans start with AI off; enabling it requires choosing a monthly credit allowance. The free tier cannot generate.

What uses credits

Plans

21st AI generation requires Builder or Team with AI enabled and available credits. Paid plans unlock the whole marketplace. Builder starts with AI off and no monthly credits; turning AI on requires choosing 500, 1,000, or 2,000 credits per month and unlocks the AI features. On the free tier, browsing and search are free but generation is unavailable.

Free

Free forever. Full marketplace browsing, unlimited UI inspirations, and two free retrievals per day — a component copy or install, an icon, a theme or a prompt all draw on the same two. Search is free. 21st AI generation is not included — use a paid plan with available credits to generate.

Builder

AI is off by default. Without AI, Builder unlocks unlimited component copy and install for $8/month billed quarterly or $6/month billed yearly. Turn on AI by choosing 500, 1,000, or 2,000 credits / month; the configured totals are $20, $40, or $80 per month billed quarterly, or $15, $30, or $60 per month billed yearly. AI-enabled Builder adds multi-model component generation, premium models, and priority generation capacity.

Team

Seats start with AI off at $10/month billed quarterly or $7.50/month billed yearly. For AI-enabled seats, choose 500, 1,000, or 2,000 credits / month per seat. Their configured per-seat totals are $25, $50, or $100 per month billed quarterly, or $18.75, $37.50, or $75 per month billed yearly. Monthly allowances combine in the Team’s shared pool. Includes centralized billing, shared collections, and admin controls.

Buying more credits

With AI enabled and running low? Buy a credit pack: +100 credits for $5. Pack credits roll over and are used after the included monthly allowance. You can also turn on auto top-up (off by default) to buy a pack automatically when you run out, up to a monthly cap you set.
Paid plans are billed quarterly or yearly. For current prices and exact allowances, the live pricing page is always the source of truth.
