One of the best parts of the early web was View Source. You could right-click any page and learn how it was built. Glorious.

But that only ever applied to the front-end. Back-ends? Proprietary. Learning to write great web apps meant books, tutorials, and hello-world code—not production-grade software.

The O’Saasy License fixes that. It’s MIT, but reserves commercial SaaS rights for the copyright holder. More open source, creators still get paid.

We need more production-grade code to teach juniors and LLMs. A view source that extends to the back-end. Fix bugs, propose features, run it yourself for free.

This is what DHH’s doing with Fizzy, and now O’Saasy has a home at osaasy.dev. Download it, use it, and maybe we’ll finally see more real SaaS code in the wild.
