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.; curl open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
- They diverge on capability: Cucumber covers Gherkin syntax, curl covers HTTP/HTTPS.
- 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.
curl
- Open-source with no vendor pricing: curl is free and open-source under GPL 3.0; no subscription or licensing costs apply
- Commercial support costs hidden: site references 'commercial support available' but pricing is not detailed or accessible from homepage
- No SaaS model: curl is a command-line tool and library; costs are limited to optional commercial support contracts (pricing unknown)
- Self-support burden: free software means customers rely on community forums or undisclosed commercial support pricing

Questions people ask
- Is Cucumber or curl better?
- Neither clearly leads. Cucumber starts at Free and curl at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Cucumber or curl?
- Cucumber starts at Free and curl at Free.
- Does Cucumber or curl run on more platforms?
- Cucumber runs on Linux, macOS, Windows. curl runs on Linux, MacOS, Windows, Unix, Mobile.
- Can I use Cucumber for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Cucumber best used for?
- Cucumber is most often used for a team practising behaviour-driven development that wants shared, readable specifications between product owners and engineers, an organisation wanting living documentation that stays synchronised with actual test coverage rather than a separate specification document, a qa team migrating acceptance tests from a proprietary bdd tool to an open source, community-governed alternative, a java, javascript or ruby project needing a mature bdd framework rather than building gherkin-style parsing from scratch. Of those, a team practising behaviour-driven development that wants shared, readable specifications between product owners and engineers and an organisation wanting living documentation that stays synchronised with actual test coverage rather than a separate specification document are not what curl is typically brought in for.
- What can Cucumber do that curl cannot?
- Cucumber covers Gherkin syntax, Step definition binding, Multi-language support, Living documentation. curl covers HTTP/HTTPS, FTP, Multiple protocols, Universal compatibility.
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.
curl: How much does curl cost?
curl is free and open-source software under the GPL 3.0 license. There is no cost to download, use, or modify the software.
SourceCucumber: Is Cucumber free?
Yes, entirely open source with no licence fee across all its language implementations.
curl: Is commercial support available for curl?
Yes. The curl website references 'commercial support available,' but pricing and details are not disclosed on the homepage and require visiting the support page.
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.
curl: Can I sponsor curl financially?
Yes. The curl website offers an option to 'Sponsor curl financially.' Visitors can donate to support curl development, but the donation link must be accessed through the site's support section.
