# Healthchecks, Open Source Kickback, and Variables Autocomplete

This week, we bring long awaited improvements to the developer experience on Railway. We've made it easier to ensure your deploy is working with Healthchecks, began work on a Variables revamp with Autocompletion, and lastly- began to integrate the Open Source Kickback directly in our product.

## Project Healthchecks

How can you guarantee the new version of your app is live and able to handle requests? By using our new configurable healthcheck! Go to Deployments → Settings and fill out **Healthcheck**:

Railway will ping this endpoint and ensure it returns a successful response before cutting traffic over to the new version of your deployment.

## Open source kickback landing page

A few weeks ago, we announced our open-source kickback program. An initiative where we give open-source project owners a percentage of what we make when a user deploys their project on Railway.

This week, we built a landing page explaining in detail how the kickback program works. To sum it up, we pay (in Railway credit) *open-sourcerers *25% of whatever we make whenever a user is billed for using their project.

Check it out at [railway.app/open-source-kickback](https://railway.app/open-source-kickback).

## Autocomplete for template variables

Last week, we introduced our new UI for r[aw SQL queries](https://railway.app/changelog/2021-10-22#raw-sql-queries) with autocomplete for SQL keywords and table-related data. This week, we extended that autocomplete behaviour to our environment variables UI where we now automatically prompt template variables to our users!
