The short version

  • Each has a real cost: 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; Signal signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
  • They diverge on capability: RudderStack covers Data collection, Signal covers End-to-end encryption.

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

Signal

  • Signal must be installed on a phone before the desktop app can be used, so there is no phone-free desktop-only account
