Gradio versus NiceGUI
Compare	Gradio	NiceGUI
Verdict	Worth it	Depends
Best for	ML researchers demoing models	Python teams building internal tools
Who it's not for	Production, customer-facing apps	Pixel-perfect consumer-grade frontends
Privacy	Recurring CVEs (path traversal, info disclosure, ACL bypass) mostly hit publicly shared or self-hosted apps . patch fast and strip secrets.^⁸	Mixed: multiple public CVEs in 2025-2026 (XSS, upload-path RCE, DoS, info disclosure); maintainers publish security guidance.
Support quality	No support evidence in sources reviewed	Docs complaints; community-dependent help
Public sentiment	ML practitioners and reviewers call it the quickest way to demo models, while warning it isn't built for production.	Developers praise NiceGUI's Pythonic ease but flag docs gaps, UI polish, and production-readiness doubts.
Biggest gotcha	File-read bugs have let attackers steal secrets from public apps . never hardcode HF tokens^⁹	CVE-2026-25732 is an upload path-traversal RCE; audit file-upload flows before public exposure.
