Choose c15t for broader framework support, individual vendor choices and a supplied consent backend. Compare CookieYes SDKs and hosted services fairly.

c15t is the stronger fit when your products span multiple web frameworks and need individual vendor choices alongside category consent. Your team can use native components, own the interface and choose where policy and records live.

CookieYes offers both a hosted service and open-source SDKs. Its SDKs include React components, Next.js server support, headless primitives and a JavaScript core. Both tools offer these features.

Use c15t's framework guides to connect each application to the same consent model. A Vue product and a React account page can each use native components.

With vendor consent, a visitor can accept a category but refuse one named vendor. The interface and registered integrations can use that choice.

CookieYes also offers reactive state and category controls. Its reviewed network rules use categories. The cited guides do not establish an equivalent individual-vendor preference model outside TCF.

This distinction matters when two services serve the same purpose but a visitor wants only one of them. Test that case in both tools.
