ExpressionEngine add-ons
Tools for the sites you're proud of.
Nerdgency makes add-ons for ExpressionEngine that stay out of your markup, explain themselves, and hold up on the sites that matter. Every one is documented to the last parameter.
{exp:formidable:form form_handle="contact"}
Products
Built for ExpressionEngine, and nothing else.
Forms, signatures and Vite. Each add-on does one job thoroughly, follows ExpressionEngine's conventions, and leaves the front end to you.
Formidable
Forms for ExpressionEngine
Build forms in the control panel or keep the ones you wrote. Conditions, multi-page and repeating sections, submissions you can work with, workflows, and a JSON API.
- Visual builder, or capture your own markup
- Themes you change one part at a time
- Email, webhooks and CRM connections
Autograph
Signatures for Channel Forms
A signature fieldtype for ExpressionEngine, for capturing signatures directly through Channel Forms.
Vitesse
Vite for ExpressionEngine
Vite's dev server while you work, and its hashed, preloaded build when you publish, from one template tag.
How we build
Three promises, in every add-on.
Your markup stays yours
Sensible output from a single tag, and every layer of it replaceable. Nothing is locked in a template you can't reach.
The server has the last word
What the browser shows is a convenience. What gets stored is decided again on the server, every time.
Documented to the parameter
The docs are checked against the source on every build, so a parameter you read about is a parameter that exists.
