Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
For example, Mailjet created its own template language as well as an email framework, MJML. You can build independent templates and send them with any provider without a need to stick to Mailjet. MJML is the most popular responsive framework, which uses custom tags. On GitHub, you will find several comprehensive tutorials on building personalized emails including abandoned cart and e-receipt.
As for template languages, Handlebars and Jade are among the most popular ones.
