OKZest

OKZest is a dynamic image personalization platform that generates a unique image for each viewer in real time. Data such as the recipient's name, company, score, or an automated website screenshot is injected into a template at the moment the image is viewed, so a single URL can serve thousands of different versions. The output is a standard image URL, which means it can be embedded in emails, web pages, chatbots, or anywhere else a normal <img> tag works.

The workflow starts in a drag-and-drop template editor where you layer text and images and mark fields with merge tags. When a recipient opens an email or loads a page, OKZest renders the image with their data filled in — content can even change after an email has been sent, since generation happens at open time. Non-technical users can trigger image creation through Zapier or Make, connecting CRMs, forms, spreadsheets, and e-commerce data. Developers can call a REST API that accepts JSON and returns an image URL for use in custom applications. There is also MCP support for wiring the platform into AI assistants.

Beyond marketing images, OKZest includes a certificate generator that produces personalized certificates from a single template, updating values like name, score, rank, and date in real time. Team features cover roles, projects, and custom permissions, so design, marketing, and client-facing staff can share one account. The editor includes royalty-free images from Pexels and font options such as drop shadows and borders. Pricing starts with a free plan — described as a free plan for life — that includes 2,500 watermarked images per month with no credit card required. Paid plans exist, but the reviewed pages don't list exact tiers or prices; the site states that all features are available on every plan, with usage limits as the main difference.

Frequently asked questions

Is OKZest free?

There is a free plan with 2,500 watermarked images per month and no credit card required. Paid plans increase usage limits, but the pages reviewed don't show their exact prices.

How does personalization work if I only embed one image?

You build a template with merge tags and embed a single URL. The platform renders a unique version of the image each time it's viewed, using the data you pass in.

Can I use it without writing code?

Yes. The template editor plus Zapier and Make integrations cover no-code workflows. Developers who want programmatic control can use the REST API instead.

Where can the generated images be used?

Anywhere a standard image URL can be embedded: email campaigns, websites, chatbots, social posts, and certificate pages.

Do free-plan images have a watermark?

Yes. The 2,500 monthly images included on the free plan are watermarked; removing the watermark requires a paid plan.

Does it support teams?

Yes. Roles, projects, and custom permissions let different functions — design, marketing, finance, or client teams — work within one account.
