NiceGUI versus Streamlit
Compare	NiceGUI	Streamlit
Verdict	Depends	Worth it
Best for	Python teams building internal tools	Data scientists building internal tools
Who it's not for	Pixel-perfect consumer-grade frontends	Non-technical teams . Python is mandatory
Privacy	Mixed: multiple public CVEs in 2025-2026 (XSS, upload-path RCE, DoS, info disclosure); maintainers publish security guidance.^⁹	One medium CVE (CVSS 4.7) found; vendor maintains a public security page.¹⁶
Support quality	Docs complaints; community-dependent help	Active community forum; no paid support evidence
Public sentiment	Developers praise NiceGUI's Pythonic ease but flag docs gaps, UI polish, and production-readiness doubts.^⁷	Sources show wide adoption in research and data science, with the main complaint being slow, reboot-prone free hosting.
Biggest gotcha	CVE-2026-25732 is an upload path-traversal RCE; audit file-upload flows before public exposure.^⁹	Free Community Cloud apps reportedly load slowly and reboot mid-session
