Building it yourself means owning two signing chains, a certificate renewal calendar, an APNs client, and a device registration database. Passmint owns those and exposes one API. Generating a pass takes an evening either way; the difference is everything that happens after the first pass ships.
| Dimension | Passmint | building it yourself |
|---|---|---|
| Time to first signed pass | About five minutes, following the quickstart | An evening for Apple only, longer once Google is in scope |
| Pass Type ID certificate | Managed, including renewal | You hold it, and you remember to renew it |
| WWDR intermediate | Managed | You track a second expiry with its own schedule |
| Both wallets from one definition | Yes | Two integrations, two formats, two signing models |
| Live updates after install | Change a field; the push and refetch are handled | You build the update web service, device registry, and APNs client |
| Where the code runs | Any runtime with Web Crypto | Whatever you build for, usually Node with native crypto |
| Ongoing maintenance | None on the signing path | Certificate rotation, API changes, and platform policy shifts |
| Cost at low volume | Free up to 10 active passes, then from $15/mo | Free, apart from your own engineering time |
