OKZest is an image personalization platform that lets marketers and developers automate the creation of personalized images at scale. Users build one branded image template, add merge tags for the elements that change, and OKZest renders a unique image for each recipient the moment it is viewed, embedding it in emails, newsletters, chatbots, certificates, social media, or websites as a standard HTML img tag. It offers both a no-code visual design tool for marketing teams and a REST API with MCP server support for developers.
