The short version

  • Only Stainless has a free tier, so it costs nothing to try first.
  • Each has a real cost: Stainless starter and Pro plan prices are not published and require contacting the company.; 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: Stainless covers SDK generation, 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.

Stainless

  • Starter and Pro plan prices are not published and require contacting the company.
  • The free plan caps APIs at 25 endpoints, which excludes larger production APIs.
  • Overage charges apply per SDK/endpoint/month once limits are exceeded, which can make costs unpredictable at scale.

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.

Stainless: What happens if I exceed my plan's endpoint limit?

Customers exceeding their endpoint limits are billed per SDK, per endpoint, per month for the overage.

Source
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.

Yodlee: Is pricing published?

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