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 Design Bug Bot pull request reviews using AI credits,
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.
Design Bug Bot
Design Bug Bot reviews connected GitHub pull requests and periodically checks the default branch for UI problems. It suggests specific code changes. Screenshots add visual evidence when rendering works; a complete source analysis still returns its recommendations as Code-backed recommendations when a screenshot is unavailable. Every personal account or team gets five successful reviews free, with no subscription or expiration. No UI changes, failed, and incomplete reviews do not use a successful-review slot. A team shares one allowance across its repositories; reconnecting or adding another repository does not reset it. After five successful reviews, new reviews require a subscription with AI enabled and use its available AI credits. A Builder subscription without AI or leftover credits without an AI-enabled subscription do not unlock more reviews. If access or credits are missing, reviews pause and show the next step. You can disable reviews in repository settings. Reviews started for free stay free.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.
