Best forNew TypeScript-first projectsdevelopers running TypeScript
Who it's not forTeams migrating large Node codebases expecting zero frictionAnyone wanting the Toronto Stock Exchange
PrivacyPermission-model runtime with real 2026 CVEs (auth bypass, info disclosure); secure-by-default claims questioned by academic studies.One transitive esbuild vulnerability fixed in tsx v4.21.0; no dedicated security page found. (Intel 'TSX Asynchronous Abort' CVEs are unrelated hardware issues.)
Support qualityNo support evidence in sourcesNo evidence on support responsiveness
Public sentimentUsers like Deno's built-in TypeScript and developer experience but report migration friction, npm incompatibilities, and a smaller ecosystem than Node.⁵No formal ratings found; developer discussion centers on tsx as a modern replacement for ts-node.14
Biggest gotchaPermission sandbox has real bypass CVEs; not a hard security boundary⁹esbuild vulnerability required upgrading tsx to 4.21.0 . watch transitive dependencies
