Getting started

What is Hirune?

A store for apps that were built partway and left to nap — try them, buy a version, and finish them with your agent. It brings together version-by-version distribution of self-built apps, a playground you can try after signing in, and directions to the AI PLAY GUILD learning community.

Do I need an account?

Signing in is required to buy apps, unlock downloads, and use the playground. You can sign in with your email address.

What is a passcode?

A keyword you receive from a paid note article. Entering it on an app page unlocks the download for the corresponding version.

Payment

How can I pay?

By credit card via Stripe. Visa, Mastercard, American Express, JCB, and others are accepted.

How do I cancel?

Anytime from the Stripe customer portal on the account page (/account). Access continues until the end of the current period; no prorated refunds.

Can I get a refund?

Generally no, because the products are digital content. We handle cases individually when a Hirune-side defect prevents delivery or a payment error such as double billing occurred. See the Commercial Disclosure for details.

Do you issue receipts?

The payment confirmation email sent by Stripe can be used as your receipt.

Using the apps

ZIP vs. the Deploy button?

The ZIP is a full package to run in your own environment. The Deploy to Cloudflare button is a launcher that deploys the same app directly to your own Cloudflare account.

Can I pick older versions?

Yes. On each app page, the version list lets you download versions you purchased or unlocked with a passcode.

What kind of apps are available?

Mostly apps used from MCP-capable AI agents such as Claude Code or Codex. See the app list for the current lineup.
