It conforms to a subset of the Heroku Platform API, which means you can use the same tools and processes that you use with Heroku, but with all the power of EC2 and Docker; Envoyer: A brand new way to deploy PHP and Laravel applications with zero downtime. Envoyer deploys your PHP applications with zero downtime. Just push your code, and let Envoyer deliver your application to one or many servers without interrupting a single customer.
