The short version

  • Each has a real cost: Activiti the last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.; 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: Activiti covers BPMN 2.0 engine, curl covers HTTP/HTTPS.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Activiti

  • The last stable release was 8.2.0 in January 2024, and while release candidate builds continue, a two-year gap between stable versions is a real risk signal for a production dependency.
  • Both Camunda and Flowable forked away and took large parts of the contributor base with them, so the community, tutorials and third-party tooling around Activiti are much thinner than around either fork.
  • Commercial support is only realistically available by buying Hyland Alfresco subscriptions, so there is no way to pay for Activiti support on its own.
  • Activiti Cloud imposes a distributed architecture of several Spring Boot services plus Keycloak, which is heavy for teams who simply wanted an embeddable engine.
  • Documentation is dated and partly split between old Alfresco sites and Hyland Connect, and the transition between Activiti 6, 7 and 8 architectures makes much of the older material actively misleading.

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
