The short version

  • Only KeystoneJS has a free tier, so it costs nothing to try first.
  • Each has a real cost: KeystoneJS database support is limited to PostgreSQL, MySQL and SQLite; Rutter a unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
  • They diverge on capability: KeystoneJS covers REST API, Rutter covers Accounting and ERP.
  • Prices and features above were last checked on 31 August 2026.

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

Rutter

  • A unified schema exposes only the fields common across platforms, so the platform-specific detail underwriting models want usually requires passthrough calls and per-platform code, which is the work the unified API was bought to avoid.
  • Write operations into accounting systems are where these products break, because each system validates differently, and a rejected journal entry surfaces as a support ticket against you rather than against the ERP.
  • No pricing is published beyond a sandbox trial, so cost cannot be compared against alternatives without a sales process, and pricing tends to scale with connected accounts.
  • QuickBooks Desktop and other on-premises systems require a local connector or hosted agent, which introduces installation steps your customers must complete and support burden you inherit.
  • Sync freshness varies by platform and by customer authorisation state, so a product promising near real-time figures will find some connections update far less often than the marketing implies.
