DevShelf
DevShelf is an open-source community directory for discovering verified free developer tools and APIs.
DevShelf provides a curated directory of free developer tools, verified free APIs, AI agents, and developer resources with zero paywalls. It solves the issue of link rot and trial-bait tools by using continuous CI health checks to verify every endpoint. Users can access the directory through an interactive web app, a terminal CLI using npx devshelf, an open JSON REST API, and an official Model Context Protocol server for AI coding assistants. It is designed for developers who want to discover reliable open-source utilities and free APIs without navigating paywalls or broken links. The platform also offers social media amplification for merged submissions.
