Sourced.dev

Read the actual source of any PyPI or npm package — every file, every version — as if the dependency were checked out locally.

Summary
The fix for a model that confidently describes an API that changed two releases ago.

Instead of recalling how a library works, the agent reads the version you actually depend on — read, grep and glob are the same three moves it already uses on your own code, pointed at a dependency's tree. Pinning by version is the part that matters most: the answer comes from the release in your lockfile, not from whatever was current during training. New releases show up within 5 minutes of publication, so this stays useful for packages that move quickly.

What it is

A hosted service that indexes the source of every published PyPI and npm package and exposes it through three familiar file tools.

What you get
  • read — a file from a package's source, with line numbers
  • grep — a regex search across a package's whole source tree
  • glob — files matching a pattern inside a package
  • Every tool takes an ecosystem, a package_name and an optional version, defaulting to the latest release
  • 800,000+ Python packages and 3,000,000+ npm packages, with new releases indexed within 5 minutes of publication
  • Ready-made configuration for a long list of coding agents, written by the installer
Requirements

A GitHub account — the one-line installer authorizes through GitHub, creates an API key and configures your agents, then you restart them. Maven, Gradle, RubyGems and Crates.io are listed as planned, not available.

Setup effort

One command — curl -sL sourced.dev/install | sh
