Pricing
Buy it once. It's yours.
Shopify's cheapest plan costs more than KahunaCart every single year, forever. Here, you pay once per site, and renewal is a choice, not a hostage situation.
includes a year of updates & support
- The complete platform: catalog, checkout, tax, shipping, digital delivery, accounts, admin
- Stripe, Polar, PayPal, offline, and the test provider bundled
- SQLite, MySQL, or PostgreSQL
- Unlimited products, orders, and customers. It's your database.
- No transaction fees from us, ever
After the first year
Keeps you on the latest version, with every new feature and every security fix. Skip it and your store keeps running on the version you have: nothing gets disabled, ever. Renew later whenever you want to jump forward.
Ecommerce needs this in a way a blog never will: payment providers change their APIs constantly, and the renewal is what keeps fourteen live integrations current.
Founders lock in $29/year for the life of the license.
One renewal covers everything on the site. Provider add-ons are one-time purchases, and your site's single renewal keeps every add-on you own updated. No per-plugin renewal stack, no surprise invoices.
Questions
The fine print, in plain words
What happens if I never renew?
Your store keeps working on the version you have, with no time limit, no nag screens, and nothing disabled. Renew later and you jump straight to the current version. One honest caveat: security fixes and compatibility work land in new versions rather than being backported, so a store that never updates won't receive them, and a major PHP or Grav upgrade down the road may eventually need a current version to run on.
Is this hosted? Do you touch my data?
No and no. KahunaCart runs on your own server, on any ordinary PHP host. Products, orders, and customers live in your database. We never see your sales, your customers, or your revenue.
Do I have to worry about PCI compliance?
Card entry happens on your payment provider's hosted, PCI-compliant checkout page, so card numbers never pass through your server. Your site handles the catalog, the cart, and the order record; the provider handles the sensitive part.
What do I need to run it?
A Grav 2.0 site and PHP. SQLite works out of the box with nothing to configure; point it at MySQL or PostgreSQL if your shop outgrows it.
What does early access mean, honestly?
The core is solid and heavily tested, with over 3,900 automated tests and a full security audit behind it. But no amount of testing replaces real stores selling real things. Early access buyers get half price now and a $29/year renewal forever, in exchange for helping find the rough edges before 1.0.
Can I use my existing Grav theme?
Yes. KahunaCart ships theme-agnostic templates and Twig functions, so you can drop a buy button or a product grid into any theme. The free Kahuna theme is there if you'd rather start from a storefront design.
Let's build some stores.
Half price during early access, a founders renewal locked at $29/year, and a store that's yours for good.
