Npmjs vs NuGet Gallery

Npmjs lands on Worth it, and NuGet Gallery lands on Depends.

Npmjs

Worth it

Confidence: Medium

If you write JavaScript, npm is effectively mandatory . it's the default package registry and free for public packages.

Depends

Confidence: Medium

Nothing to buy: if you build .NET, this is the default public package registry and you simply use it.

Npmjs versus NuGet Gallery
Compare	Npmjs	NuGet Gallery
Verdict	Worth it	Depends
Best for	JavaScript/Node.js developers	.NET/C# developers
Who it's not for	Non-JavaScript stacks . use PyPI, NuGet, or Maven instead	Anyone needing private or internal package hosting
Privacy	High-risk: repeated supply-chain compromises, including a Sept 2025 worm affecting 19 popular packages; 19 CVEs tracked.^⁷	Two CVEs against the Gallery itself (2024 input flaw, 2026 critical RCE), rising typosquatting pressure; the 2025 deletion incident was officially not a breach.
Support quality	Reddit users call the site abandoned	FAQ, status page, GitHub issues; no paid support.
Public sentiment	Review volume is tiny; G2 users find package management easy, while Reddit threads criticize site neglect, publishing friction, package quality, and security.^²	Users treat as indispensable .NET infrastructure, but the 2025 package-deletion incident and supply-chain chatter eroded some trust.¹⁶
Biggest gotcha	One compromised maintainer account can push malicious updates to hundreds of millions of weekly installs.	Typosquatting and dependency-confusion attacks are rising; double-check exact package names before installing.
