NiceGUI versus Gradio
Compare	NiceGUI	Gradio
Verdict	Depends	Worth it
Best for	Python teams building internal tools	ML researchers demoing models
Who it's not for	Pixel-perfect consumer-grade frontends	Production, customer-facing apps
Privacy	Mixed: multiple public CVEs in 2025-2026 (XSS, upload-path RCE, DoS, info disclosure); maintainers publish security guidance.^⁹	Recurring CVEs (path traversal, info disclosure, ACL bypass) mostly hit publicly shared or self-hosted apps . patch fast and strip secrets.
Support quality	Docs complaints; community-dependent help	No support evidence in sources reviewed
Public sentiment	Developers praise NiceGUI's Pythonic ease but flag docs gaps, UI polish, and production-readiness doubts.^⁷	ML practitioners and reviewers call it the quickest way to demo models, while warning it isn't built for production.
Biggest gotcha	CVE-2026-25732 is an upload path-traversal RCE; audit file-upload flows before public exposure.^⁹	File-read bugs have let attackers steal secrets from public apps . never hardcode HF tokens
