The short version

  • Only Apollo GraphQL has a free tier, so it costs nothing to try first.
  • Each has a real cost: Apollo GraphQL pricing beyond the Developer tier requires contacting sales, making cost comparison harder for mid-size teams.; Solaris baFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • They diverge on capability: Apollo GraphQL covers Apollo Connectors, Solaris covers German banking licence.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Apollo GraphQL

  • Pricing beyond the Developer tier requires contacting sales, making cost comparison harder for mid-size teams.
  • Adopting GraphOS effectively requires buy-in to the GraphQL paradigm, which is a larger architectural shift than adding a REST gateway.
  • The free plan's 1-day data retention and 60 req/min self-hosted router limit make it unsuitable for production use.
  • Volume-based per-request pricing can become expensive at very high request volumes compared to flat-rate API gateways.

Solaris

  • BaFin appointed a special representative in 2022 and extended the mandate in July 2024, so a partner is joining a bank under active supervisory monitoring, with slower approvals and heavier compliance demands as a direct consequence.
  • BaFin fined Solaris EUR 6.5 million in March 2024 for systematically late suspicious activity reports and EUR 500,000 for breaching large exposure limits between January 2022 and March 2024, which is a track record a partner inherits reputationally.
  • Solaris has previously needed BaFin approval before onboarding new corporate clients, which can turn a commercial decision to launch into a regulatory timetable outside your control.
  • The 2024 restructuring involved job cuts and the closure of parts of a business unit, so product lines a partner depends on may not have the engineering behind them that the sales process implies.
  • SBI Holdings acquired majority control in 2025, so strategic direction now sits with a Japanese financial group whose priorities for the European business may differ from the roadmap you were sold.
