The short version

  • Each has a real cost: Cucumber gherkin's plain-language layer adds a real maintenance burden, keeping feature files, step definitions and implementation code synchronised across a large suite is a known source of drift and duplicated effort.; PostHog the free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • They diverge on capability: Cucumber covers Gherkin syntax, PostHog covers Product analytics.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Cucumber

  • Gherkin's plain-language layer adds a real maintenance burden, keeping feature files, step definitions and implementation code synchronised across a large suite is a known source of drift and duplicated effort.
  • Ownership has moved twice in under a decade, from independent to SmartBear-owned to independent community ownership again, which should temper confidence in any specific long-range roadmap claim.
  • Non-technical stakeholders who are meant to read and write Gherkin scenarios often do not engage with them in practice, leaving the readability benefit unrealised while the maintenance cost remains.
  • Step definition reuse across a large feature file set can become tangled, with ambiguous step matching causing hard-to-debug failures as a suite grows.
  • As a community-owned project without a corporate backer's support infrastructure, enterprise buyers wanting a formal support contract have no vendor to buy one from, unlike some competing BDD tools still sold commercially.

PostHog

  • The free tier covers 1M events, 5K web session recordings and 2.5K mobile recordings per month before usage-based billing starts
  • Accounts without a card on file are limited to 1 project; adding one raises it to 6
  • Data retention is 1 year until a card is added, which extends it to 7 years
  • Support is community-only until the account is on a paid plan
  • Error tracking is capped at 100K exceptions and surveys at 1500 responses per month on the free tier
