Plans

Free vs Pro
Yearly Pro is $250/year (shown as $21/mo billed annually, 42% off $36). Monthly is $25/mo (30% off $36). See Manage billing.
AI model
Everyone uses the same Standard coding agent (Free and Pro). There is no model picker in chat. Pro unlocks workspace features and more credits — not a different model. Underlying providers are not shown in the product.Where to manage your plan
In the app, open Plans & credit usage (/billing) from the workspace menu or account menu. Locked Free features (export, GitHub, custom domain, more credits) navigate there too.
Custom domains (Pro)
Pro includes custom domains — marketing may show this as “Free custom domain” (meaning included with the Pro plan, not available on the Free plan). Domain registration is billed separately from the Pro subscription (Stripe). Manage domains at/settings/domains or from Publish on a live project.
See Custom domains.
How to choose
- Free — try the product: Standard AI, Preview + terminal, publish from shared credits (hard-pauses when empty), read-only code
- Pro — edit/export/GitHub, credit top-ups, custom domain; same credit balance for chat and hosting
- Enterprise — organization-wide needs
