ripienaar/free-for-dev ? reverse-engineered prompt

I want to build a simple, single-page website that serves as a big directory of free services for developers and DevOps people. The goal is to create a go-to resource for finding SaaS, PaaS, and IaaS products that have a generous "always free" tier, not just a short free trial.

The site should be organized into logical categories like Major Cloud Providers (AWS, Google Cloud, Azure), CI/CD, Databases, DNS, Web Hosting, Monitoring, and so on. Under each category, list the service, a link to it, and a quick summary of what its free plan includes.

Please research and compile this list for me. Focus on services useful for infrastructure and development. The design should be clean, text-heavy, and fast-loading, maybe with a table of contents at the top that links to the different sections on the page.
