The short version
- Each has a real cost: Hoppscotch open-source project with no published commercial support plans or pricing; JUnit there is no large foundation or major corporate backer, unlike Jest under OpenJS or Cucumber under SmartBear, so long-term stewardship rests on a comparatively small independent team.
- They diverge on capability: Hoppscotch covers REST Client, JUnit covers Annotation-based test definition.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Hoppscotch
- Open-source project with no published commercial support plans or pricing
- No official enterprise tier or SLA information disclosed
JUnit
- There is no large foundation or major corporate backer, unlike Jest under OpenJS or Cucumber under SmartBear, so long-term stewardship rests on a comparatively small independent team.
- Commercial support is available only through OpenElements, a small specialist firm, not a major vendor with broad enterprise support infrastructure.
- Migrating a large legacy codebase from JUnit 4 to JUnit 5 idioms takes real effort even with the Vintage compatibility engine, since new features are only available in the Jupiter API.
- The extension model, while powerful, has a learning curve that teams building custom test infrastructure need to invest in before it pays off.
- Being free and community-maintained, feature requests compete for a small team's time with no commercial escalation path beyond the OpenElements support arrangement.

Answered from the vendors’ own pages
Hoppscotch: Is Hoppscotch free to use for API development?
Yes, Hoppscotch is a completely free, open-source API development ecosystem. There are no subscription fees, license costs, or registration requirements to access the core platform.
SourceJUnit: Is JUnit backed by a foundation like Apache or Eclipse?
No, it is maintained by an independent JUnit Team without a formal foundation affiliation, though some lead maintainers also work on Eclipse-related tooling.
Hoppscotch: Can I deploy Hoppscotch on my own infrastructure?
As an open-source project, Hoppscotch can be self-hosted and deployed on your own infrastructure. The source code is available for customization and deployment in private environments.
SourceJUnit: Can I buy commercial support for JUnit?
Yes, several core JUnit 5 maintainers offer commercial support and consulting through a company called OpenElements.
JUnit: Do I need to migrate from JUnit 4 to JUnit 5?
Not immediately; the Vintage engine runs JUnit 4 tests unchanged on the JUnit 5 platform, but new features require migrating to the Jupiter API.
