In past years, innovation in cloud services has made it quite convenient to host static websites. Since they don't require servers, these sites are usually faster, more secure, and cheaper to host/maintain than their dynamic counterparts; making them perfect for something like your new landing page. But what if you need to gather data from your visitors? You could add an html form, but you would need some sort of back-end for doing things like saving submission data or sending notifications. A web form is in essence a very simple application. a user interacts with an interface (the form) and submits a request with the form data to a server that processes it and then returns a response. A web form can be useful for collecting things like contact information from leads, email addresses for a mailing list, responses for a survey, payments for goods/services, and much more. Super easy forms is an open source and easy to use solution that uses services from the AWS cloud to help you generate your own fully customizable serverless contact forms (front-end and back-end). Some of the Benefits of Super Easy Forms Free and Open Source Fast and easy to use Completely customizable (front-end and back-end) Create unlimited projects, forms and submissions Monitor your forms and retrieve submissions locally has several built-in options like CAPTCHA To learn more about super easy forms check out and . If you want to see the source code or adapt it for your use case go to the project's . our website read the docs repository Why Serverless? serverless, or function as a service (FaaS), refers to an infrastructure as a service model were a cloud provider dynamically allocates machine resources and charges you a variable cost per execution load/time. There's a lot of fuzz in the community about AWS lambda and serverless technology. Some people love it and want to use it for everything while others hate it. Personally, I'm a big supporter of serverless technology but Im aware that its not meant to be used for everything. Alike any new technology its got its perks and drawbacks and these should be assessed before any implementation. As a rule of thumb, code that you execute inside lambda should be a function with defined inputs and outputs and a short execution time. In the case of super easy forms, we found it convenient to use AWS lambda because its a fully managed service but it still allows us customize the backend of each form independently. Also since form submissions aren't constant (high idle time) paying a completely variable cost per execution is more convenient than paying the fixed monthly cost of a virtual machine. Getting Started with Super Easy Forms Before you begin you will need an AWS account. If you don’t have one you can easily create one .

It stores the form output in a DynamoDB table. It sends an email message to notify stakeholders about a new form submission Collaborating Want to help make Super Easy Forms better?
