Passmint vs building wallet passes yourself

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	Yours; Passmint generates and holds the key and shows expiry	Yours; you export the .p12 and 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

When building it yourself is the better choice

You would rather hold the signing key yourself than have anyone hold it for you, for contractual or compliance reasons.
Wallet passes are the product rather than a feature of it, and the signing pipeline is something you want to own end to end.
You are issuing a handful of passes that never change, in which case a static .pkpass generated by a script is genuinely enough.
Your organisation cannot send pass data to a third party at all.

When Passmint is the better choice

You need both wallets and you would rather write one integration than two.
Your passes change after install, whether gate numbers, balances, or appointment times, and that is where the real engineering lives.
Nobody on the team wants to own a certificate renewal calendar.
You are running on Workers, Deno, or Bun, where native crypto modules are not available.

Common questions

Generating one is not hard. A pass is a ZIP of pass.json, images, a manifest of file hashes, and a signature, and you can build one in an evening. The hard part is the certificate chain, the update web service, and doing it all again for Google Wallet.

Usually the certificate. A Pass Type ID or WWDR intermediate expires on a day nobody is watching, and every new pass silently stops signing while already-installed passes keep working, so the failure is easy to miss.

Yes, for live passes. Apple requires passes to be signed under the issuing brand's own Pass Type ID, whoever generates the bytes. The difference is the work around it: Passmint generates the CSR, holds the private key, signs every pass, bundles WWDR, and shows expiry, so your part is one exchange in the Apple portal. Test mode uses Passmint's certificate so you can build before that.
