VERDICT

Should I use NiceGUI?

Easy-to-use, Python-based UI framework that shows up in your web browser. - nicegui.io

Depends. Take it if you're a Python developer building internal tools, dashboards, or quick MVPs — it's free and genuinely easy. Skip it for polished consumer frontends or public-facing apps until you've audited and patched; the CVE history is real.

Confidence

Medium. Based on 25+ public sources: Reddit threads, GitHub discussions, blogs, and CVE databases (NVD, SentinelOne, Miggo).

CVE-2026-25732 is an upload path-traversal RCE; audit file-upload flows before public exposure.

No paid support tier found; help is community GitHub plus docs, with reported gaps.

() had an XSS (CVE-2026-25516); sanitize user content before rendering.

Guess: backend-driven UI couples tightly to Python; migrating to a JS frontend later means a rewrite.

Pros and cons
