About smol developer
smol developer is a single-prompt app generator — it scaffolds a full multi-file project from a one-sentence brief.
Its whole idea is one prompt to a scaffold: an open-source CLI tool that takes a natural-language brief and generates the project structure, using your own LLM key so you control the model.
It's for developers who want a fast starting scaffold and are comfortable on the command line. Two limits: you bring and pay for your own LLM API keys, and the interface is CLI-only — no first-party IDE or web UI.
It's a one-shot scaffolder, closer to Pythagora's generate-an-app approach than to the iterative in-editor agents.
