jsDelivr versus Amazon Web Services (AWS)
Compare	jsDelivr	Amazon Web Services (AWS)
Verdict	Worth it	Depends
Best for	Open-source library authors	Enterprise engineering orgs
Who it's not for	Commercial apps needing SLAs or support contracts	Small sites and simple apps . massive overkill
Privacy	No CVEs against the service itself in sources; a 2023 incident served already-removed malicious npm packages used in phishing.^⁹	Mature security organization with public CVEs and customer-side breaches on record; shared responsibility means misconfigurations are on you.
Support quality	No support-quality evidence in sources	Trustpilot 'Bad' at 1.3/5
Public sentiment	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.^⁵	Review volume is enormous, but customer sentiment on Trustpilot is poor while marketplace ratings run higher.¹⁵
Biggest gotcha	Free means no SLA: its outages and 404s become your site's incidents. Pin exact versions.¹²	Managed services create lock-in; migrating off later is slow and expensive
