How we built Townie – an app that generates fullstack apps

Like Claude Artifacts, but with a backend and database

Recent advances in code generation (“codegen”), particularly in Claude 3.5 Sonnet, has enabled a completely new style of building software through conversation with an LLM. Tools like VSCode Copilot and Cursor let you build larger software with a frontend and a backend, but now you need a place to deploy it, which is a significant barrier to non-programmers, and slows the iteration cycle. This vision is taking shape with frontend-only apps, but if we’re really talking about “the full power of computers”, then this should include entire applications, with persistence, authentication, external API calls — really everything that professional programmers build.
