The short version
- Only RudderStack has a free tier, so it costs nothing to try first.
- Each has a real cost: Brex the free Essentials tier is limited to two legal entities; 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
- They diverge on capability: Brex covers Corporate cards, RudderStack covers Data collection.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Brex
- The free Essentials tier is limited to two legal entities
- Premium is $12 per user per month, so cost scales with headcount using the card
- Enterprise and Smart Card pricing is not published
- Eligibility criteria are not stated anywhere on the pricing page, which matters for a product that extends credit
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
