Slint versus Tauri
Compare	Slint	Tauri
Verdict	Depends	Depends
Best for	Rust or C++ desktop apps	Web teams shipping desktop apps
Who it's not for	Web app teams . not a web framework	Teams with zero Rust experience
Privacy	No known public vulnerabilities found in the sources reviewed.^⁴	Several CVEs disclosed in 2026 including SSRF, XSS, and updater auth bypass; maintainers ship patches quickly.
Support quality	No support-quality evidence in sources	Community and GitHub only; no SLA evidence
Public sentiment	Rust developers call Slint a promising, lightweight declarative GUI toolkit while flagging rendering issues, async friction, and licensing confusion.^⁸	Web developers shipping Tauri v2 apps are largely happy with size and performance, but the Rust learning curve is the recurring complaint.
Biggest gotcha	Commercial license needed beyond royalty-free desktop terms . read the FAQ before committing	Rust knowledge effectively required; debugging beyond the web layer stalls teams without it¹¹
