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
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model
