They diverge on capability: KeystoneJS covers REST API, Volt covers Pay by bank.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

KeystoneJS

Database support is limited to PostgreSQL, MySQL and SQLite
Keystone 5 is a separate legacy product documented on a different site and is not covered by the Keystone 6 docs
Upgrading requires following a dedicated Migrate to 8.0.0 guide, so major versions are not drop-in
Free support is a community Slack; enterprise-grade consulting and support is a separate paid engagement with Thinkmill and no published price

Volt

Account-to-account payments carry no chargeback mechanism, so consumers lose scheme dispute protection and merchants lose a familiar framework for handling claims.
Refunds are outbound payments rather than reversals, which changes treasury handling and means a refund can fail for reasons a card refund never would.
Conversion is lower than a stored card because the shopper must complete a bank authentication journey, and drop-off varies significantly by bank.
Core pay by bank pricing is per transaction but refunds, payouts, virtual IBANs, Verify and fraud tooling are billed separately, so the real cost is a stack of line items.
Bank API availability and quality vary across markets, and an outage at a major bank removes a slice of your checkout with no fallback unless you keep cards live.
