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

ClickHouse

  • Limited multi-row atomic transactions and expensive UPDATE/DELETE operations unsuitable for transactional systems
  • Requires upfront schema design discipline with MergeTree engine choices and sort/partition keys
  • Experimental vector search support, not production-ready for vector operations
  • Different query syntax from standard SQL requiring migration planning
  • Limited JOIN capabilities compared to traditional relational databases
  • Migration complexity with 2-4 weeks estimated for data type mapping and query translation
