# Spend $5 / month to build a full SaaS

I am building [remiind.cc](https://remiind.cc), random email reminder for your ideas.

All my tech stack is in AWS, this is my cost:

Around $5 / month.

To be clear, remiind.cc has < 100 users, and it's a simple web app. All I want to say is, it's cheap to start a SaaS.

### This is my tech stack

**Frontend:**

* reactjs as framework;
    
* S3 to host static files;
    
* CloudFront as CDN;
    
* Route53 for domain name;
    

**Backend:**

* Lambda functions + API Gateway for API and cron jobs;
    
    * I use [claudiajs](https://www.claudiajs.com/claudia-api-builder.html) to build and deploy the API;
        
* DynamoDB for data storage;
    
* S3 for file storage;
    
* [loops.so](https://loops.so) for email (I am still on the free plan).
    

I hope to pay more to AWS and loops, which means I will also earn more :)
