Extensible Software in the Age of LLMs

LLMs enable users to create highly personalized, “software for one” extensions that integrate directly into web applications, bypassing the complexity of traditional feature development. By combining a stable core with LLM-generated code and modern sandboxing, platforms can safely expose extensibility points—such as record-triggered functions or custom parsers—and allow users to share these customizations publicly. This model, exemplified by Pi and suited to Cloudflare’s Dynamic Workers, promises a new class of extensible web software.
