Hero Light ## Concept The idea of **Cascade** template is that it offers as little bloat as possible when it comes to technology choices. The only friction before fully working boilerplate on your `localhost:3000` is `.env` file with correct envorinmental variables and a database running. **Prerequisite** You should have installed Node.js (version 18.10.0 or higher). Cascade barebone setup is a Next.js app with Prisma ORM and PostgreSQL database. It takes around 10-20 minutes to set up the project locally and start developing your SaaS application. To have all services up and running, you would require couple of hours and it will mostly be setting up the hosted versions. **Good news** is that you can start with the barebone setup and add services as you go. ## Tools Most of the tools selected for Cascade are open-source(**OSS**). Some of them are self-hosted(**SH**). All tools that are SaaS have generous free plans and should get you started without any additional costs.
