VoidSay is the Modern Cusdis Alternative
Cusdis is a great open-source commenting system. But it requires self-hosting and lacks rich media features. VoidSay gives you the same privacy-first philosophy with a fully managed, feature-rich experience.
Why People Are Switching from Cusdis
Fully Managed
No server to maintain. No Docker to configure. VoidSay handles everything — just paste one embed snippet.
Richer Features
YouTube embeds, X/Twitter cards, Instagram feeds, full Markdown. Cusdis keeps it minimal — VoidSay gives you more.
Same Privacy Focus
Like Cusdis, VoidSay never tracks your readers or sells data. But you get a managed experience with zero maintenance.
