Try a working demo

This is a multistep signup demo that connects Arengu with an external API.

1. Adaptative sign up

The form can jump between steps based on advanced validation flows — asking for extra data if it's a new signup, or jumping to a step that logs users in, if it's an already registered email.

1. Inline data validation
Validation error

Form verifies user’s email with your own business rules. You can require an MX record or auto login users that have been registered before, among other options.

2. Enrich your database

Add additional questions after signup is complete. Add more user’s data to your database, by asking questions before or after registration.

3. Sign up and integrate with other tools

Add API-based integrations on top of the onboarding logic: update your Hubspot CRM or send Slack notifications, among others.

3. Auto login

Configure your onboarding flow by easily adding an auto-login if user have been registered before and no error is detected. Email, password, and logged in!

Frequently asked questions about user registration forms.

We don't handle users. Arengu allows you to easily build sign up flows that connect with your auth system or custom API but doesn't provide user management capabilities. We are basically like a middleware between your auth systems and your end-users.

We don't provide user management capabilities but we can generate and verify JWT tokens using our native flow actions. Currently we only support setting authentication tokens in cookies but we have plans to support Storage API in the future.

It’s not necessary but you will take more advantage if you are a tech profile.

Arengu is designed to save developing time from recurrent issues, like user login and registration process, providing a low code SaaS and an interface to automatize and personalize it, amplifying features of most common authentication services.

We don’t generate tokens or administrate users, but we allow you to create completely personalized forms and logics and provide a better UX for your users. Your marketing coworkers will love the results!

You need just a line of code to embed the form in all your websites and landing pages, even with popular frameworks as React, Vue, Angular, Gatsby...

Copy and paste our JavaScript SDK to your pages' HTML where you want your form to appear. It's that simple to inline embed. You can find embed options in your form editor page under the Share tab.

It’s a really easy and quickly way to provide an unified process everywhere!

You can easily integrate with common identity providers like Auth0, Onelogin, Firebase Auth and Okta, or you can connect with your own auth system if it has an API using our flows HTTP Request action.

By default, Arengu has a database per form and it stores all submitted form data and meta data. If you worry about privacy or security, you can enable or disable data persistence per form or even per field basis, this is very useful in case you want to avoid storing sensitive information in Arengu.

If you disable data persistence, remember to link a flow to your form to send it to your CRM or API, otherwise, it will be lost forever.

Everytime a flow is executed, we save all input/outputs/errors of every flow step, so in case an error comes up, you can easily debug it and fix it. You can find this debugging section in your flow editor under the "Executions" tab.
