What you give up either way

Enterprise-grade SSO, dedicated success managers and advanced user management
Polished, long-built integrations with many conferencing tools
Scale and reliability of an established service used by hundreds of thousands
Proprietary analytics and product polish (UX, moderation workflows, branding options)
Bundled proprietary AI features (Slido AI) and enterprise compliance packaging

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Slido, and it does not prove anyone has run it for a month. How we decide.
