VerdictWorth itDepends
Best forJavaScript developersNew JS/TS projects wanting one fast toolchain
Who it's not forNon-technical buyers wanting a ready-made appProduction-critical apps that cannot absorb runtime churn
PrivacyActive security program with an official security page; a 2026 HTTP/2 CVE was patched after a delayed release, and npm supply-chain malware is the main recurring risk.³Two recent CVEs (command injection, trusted-dependencies spoofing) plus active malware campaigns abusing the runtime.
Support qualityNo direct evidence in sources reviewedPost-acquisition support called limited and deprecated
Public sentimentProduct Hunt shows a perfect 5.0 rating across roughly 25 reviews, but the reviewed sources contain little substantive user feedback.²Users praise Bun's speed and resource efficiency, but the 1.4 Rust rewrite and post-acquisition support draw criticism.⁹
Biggest gotchanpm supply-chain malware exists; audit dependencies before installing.⁴Acquired December 2025 with zero revenue; priorities may shift toward Anthropic's goals.14
