Projects (Chen Fengyuan) versus jsDelivr
Compare	Projects (Chen Fengyuan)	jsDelivr
Verdict	Depends	Worth it
Best for	Frontend devs wanting small JS utilities	Open-source library authors
Who it's not for	Buyers wanting a supported product with SLAs	Commercial apps needing SLAs or support contracts
Privacy	No known public vulnerabilities found in the sources reviewed.^²	No CVEs against the service itself in sources; a 2023 incident served already-removed malicious npm packages used in phishing.¹¹
Support quality	No vendor; community-based support only.	No support-quality evidence in sources
Public sentiment	No user reviews of these projects surfaced; sources reviewed covered unrelated project-management tools.	Users on Reddit and G2 call it one of the best free JS CDNs for offloading scripts, but complain when outages and 404s break their sites.^⁷
Biggest gotcha	No vendor support, SLAs, or migration help; you depend on the GitHub community^¹	Free means no SLA: its outages and 404s become your site's incidents. Pin exact versions.¹⁴
