Shelf

Shelf gives every tool you build a place to live: one local library that launches them in a click, shares them with a coworker in two, and serves them to your AI agents under your own brand, with no cloud and no account. The pain it names is familiar to anyone building with AI, a hard drive littered with csv-de-duper.py, client-resizer-v1, and docker compose folders nobody can find again, including you last Tuesday. Shelf is a free, open-source macOS app for Apple Silicon that keeps these tools alive and addressable, so an agent can reach the utility you built last month instead of the workflow forgetting it exists. The no-account, no-cloud stance means your tools and their access stay on your machine, which is the right default for internal utilities handling real files. For teams accumulating one-off automations faster than they can document them, this turns throwaway scripts into a durable toolbox. Free download, open source.
