  • They diverge on capability: RudderStack covers Data collection, Spring Cloud Gateway covers Routing.

Where each one falls short

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

RudderStack

  • On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
  • The free plan allows 250,000 events a month
  • Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
  • Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step

Spring Cloud Gateway

  • Released under the Apache 2.0 license, free and open source with no commercial tier
