Show HN: Arengu – Easily build forms that communicate with your API

Hello HN Community!

This is Jacobo, one of the cofounders @ Arengu. I am looking to receive some feedback of what we've been working for the last months.

We've created Arengu to help building and scaling your sign-up process without dealing with complex integrations or wasting valuable development resources.

Unlike other online form builders, Arengu allows you to connect your forms with any API and execute actions at different stages of your form. This is specially useful to cover advanced uses cases like a multi-step form with SMS verification, verify if an email is valid or if it's already registered in your system, validate data against 3rd party services, sign up users or authenticate them with your API, etc.

How we do this?

- We have a flows module where you can visually build your business logic: native integrations, custom HTTP requests, if/then conditions, etc. Validation flows need to finish with a return response action with a success or failure message that will be automatically mapped to your form.

- Inside our drag & drop form builder, you can trigger flows at different stages of your form: between form steps, before submission or after submission. As an example, if your flow validates users email (valid MX record) and someone provides a fake email, it will show an error message on the browser but, if the user provides a good email, it will allow the user to continue to the next form step or submit the form.

When Arengu is useful?

- As a SaaS boilerplate. When you start building a new SaaS there is always a bunch of non-core features that you always need to develop: registration and login forms, recurring payments, task automation like sending welcome emails, notifications, email subscription, etc. Arengu helps you building all of this without development overhead so you can focus on your core app.

- To scale user acquisition campaigns. Sometimes marketing teams need to create loads of landing pages with a sign-up form and they ask dev team for help. Arengu allows them to reuse that form in as many landing pages as they want with just a line of code without dealing with technical complexity.

Our short-term plan includes

- Adding a landing page module to easily create static pages based on a HTML template with editable content (HTML, text or images).

- Support main social login providers (Facebook, Google, etc).

- Adding workspaces to organize your account.

- Support styles on form editor.

I'd love to know what you think about the product, if there is something you don't understand, if you are missing some features, etc. Any feedback or comments will be really appreciated as this is very important for us to keep improving and offering the best experience for our users.

Also I am available to schedule free 1:1 meeting to help building sign-up flows with Arengu, you can email me to jacobo.vidal[at]arengu.com

Thank you very much for your time reading this!
