Our Tech Stack

Toast’s products run on a stack that ranges from guest and restaurant-facing Android tablets to backend services in Java to internal, guest-facing and restaurant-facing web apps. Our backend services follow a microservice architecture written using Java 8 and DropWizard; we use AWS extensively, ranging from S3 to RDS to Lambda. We have our own platform for dealing with user management, service elevations and robust load balancing. Toast stores data in a set of sharded Postgres databases and utilizes Apache Spark for large scale data workloads including query and batch processing. The front-end is built primarily using React and ES6. The main Toast POS application is an Android application written in Java and Kotlin. For data between tablets and our cloud platform we operate RabbitMQ clusters as well as direct tablet communication to the back end.

Toast uses .Net/C# and Java for the backend. The front-end is primarily written in MVC, React and Angular. We also use SQL Server/Aurora postgres for our database. Other technologies include SQS, SNS, Dynamo, SageMaker, Cloudwatch, Redshift, etc.
