Frequently asked questions
How is anonymous publishing different from the free plan?
Anonymously, you get 1 site for 24 hours through the web form, with no account. On the free plan, after you sign up, a site lives for as long as people visit it.
How is yearly billing different from monthly?
With yearly billing you get 2 months free: a year costs the same as 10 months of monthly billing. You're charged once for all 12 months. With monthly billing we charge every month.
How much space do my projects get?
Storage is shared by all projects on your account: Free — 20 MB, Pro — 1 GB, Business — 5 GB. Limit per project: 200 MB, but no more than your free space. Delete a project and its space frees up.
When do I need the Pro plan?
When you need more than one site, sites without the promo banner, a PIN to hide a site from strangers, or leads collected from an HTML form.
Which plans include lead collection?
Lead collection is available on Pro and Business: Pro — 10 forms and unlimited submissions per form, Business — unlimited forms and submissions. Submissions are kept until you delete them, the form or your account.
Which plans include custom domains?
All of them, including the free one. You can connect a custom domain to every active site — the domain limit matches the plan's site limit, and the SSL certificate is issued automatically. On paid plans a site can have any number of mirrors — extra addresses that lead to the main one.
Which plans include the REST API and MCP?
All of them, including Free: you only need an account. Create an API key in your dashboard, and Claude, Claude Code, Cursor or your own script publishes and updates sites on its own. The request rate is limited by plan.
How does payment work?
By card via Stripe, with auto-renewal. You can change or cancel your plan at any time in your dashboard.
