The short version

  • Only PubNub has a free tier, so it costs nothing to try first.
  • Each has a real cost: Plaid no dollar amount is published for any product, and the pricing page states no per request rate or minimum commitment; PubNub free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • They diverge on capability: Plaid covers Bank account linking, PubNub covers Pub/sub messaging.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Plaid

  • No dollar amount is published for any product, and the pricing page states no per request rate or minimum commitment
  • Three different billing models apply depending on the product, being one time per connected account, monthly per connected account, and per successful API call
  • That mix means total cost depends on which products are combined rather than on a single unit
  • Discounted rates require the Growth plan, which is a 12 month commitment

PubNub

  • Free plan storage history is limited to 7 days, which is short for apps needing longer message retention.
  • MAU-based pricing means costs scale directly with user growth, which can be less predictable than flat message-based pricing.
  • Pro-tier custom pricing above 50,000 MAU requires contacting sales rather than self-serve checkout.
