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.; Insomnia git Sync on the free tier covers up to 3 users only
- They diverge on capability: Cucumber covers Gherkin syntax, Insomnia covers REST API Client.

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.

Answered from the vendors’ own pages
Cucumber: Is Cucumber owned by SmartBear?
No, not currently. SmartBear acquired Cucumber Ltd in 2019 but the open source project returned to independent community ownership in December 2024.
Insomnia: How much does Insomnia cost?
Insomnia offers a free Essentials plan. Pro plans cost $12 per user per month with annual billing offering 17% savings. Enterprise plans cost $45 per user per month with support for up to 50 users self-serve; contact sales for larger teams.
SourceCucumber: Is Cucumber free?
Yes, entirely open source with no licence fee across all its language implementations.

Yes, the Essentials plan is free and includes unlimited Cloud and Local projects, Git Sync for up to 3 users, 1,000 mock server requests per month, Inso CLI, E2EE, custom linting, plugins, and AI features.
SourceCucumber: Does Cucumber replace Selenium or Appium?
No, Cucumber provides the Gherkin specification layer and step definition binding; the actual browser or mobile automation still needs a driver such as Selenium or Appium underneath.
Insomnia: What mock server request limits apply to Insomnia plans?
Essentials includes 1,000 mock server requests per month. Pro includes 10,000 requests per month. Enterprise includes unlimited mock server requests. Additional mock server requests beyond plan allowances cost $10 per 25,000 requests.
