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; Yodlee ownership has changed twice in two years, from Envestnet to Bain Capital control and then to STG in 2025, so the roadmap is now set by a financial sponsor and long term product direction is harder to rely on than it was.
  • They diverge on capability: KeystoneJS covers REST API, Yodlee covers Account aggregation.
  • 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

Yodlee

  • Ownership has changed twice in two years, from Envestnet to Bain Capital control and then to STG in 2025, so the roadmap is now set by a financial sponsor and long term product direction is harder to rely on than it was.
  • Parts of the connection estate still depend on credential based access, which banks and regulators are phasing out in favour of FDX APIs, so coverage will shift as institutions withdraw the older method and the migration is not under your control.
  • The platform predates modern API design and developers consistently find the integration heavier and the data model more idiosyncratic than newer aggregators, which lengthens build time.
  • Pricing is enterprise shaped with annual commitments and nothing published, so small and mid sized buyers have no anchor and cannot start without a sales cycle.
  • Investment data, document retrieval and analytics are licensed on top of core aggregation, so the capabilities that justify choosing Yodlee over a cheaper rival are the ones that raise the price above it.

Source
Yodlee: Why choose Yodlee over Plaid?

Longer transaction history, deeper investment and held-away account coverage, and document retrieval. Those are wealth management and underwriting requirements rather than consumer fintech ones.

KeystoneJS: Does KeystoneJS offer paid support?

Enterprise support with tailored options is available from Thinkmill, the company behind KeystoneJS. Pricing details available upon request.

Yodlee: Does it still use screen scraping?

Parts of the estate rely on credential based connections, which the industry is phasing out in favour of regulated APIs. Ask for direct API coverage by institution before signing.

No. It is quoted by connected users, refresh frequency and data types, with investment data and document retrieval priced separately.
