SnapPoint is an interactive system auditor designed to help developers maintain clean and conflict-free development environments. It specifically addresses the accumulation of software debris that occurs over years of development work, tutorials, experiments, and quick installations.

The tool provides several key capabilities including finding ghost binaries (binaries in /usr/local/bin that no package manager claims), resolving PATH conflicts (such as multiple versions of Node fighting for your $PATH), cleaning cache bloat (GBs of cache for tools you deleted months ago), and identifying orphaned packages (dependencies that stayed after the parent was removed). It also includes features for scanning systems to identify every global binary and its origin story, plus ghost busting functionality to find and purge orphaned binaries.

SnapPoint works through a command-line interface where users can run commands like 'snappoint doctor' to check system health and see which package managers are available, 'snappoint scan' to discover all binaries and their origins, and 'snappoint list' to view conflicts, orphans, and ghosts. The tool provides detailed output showing exactly what's installed and where it came from, including information about conflicts and ghost binaries.

The primary benefit is maintaining a clean development environment free from the clutter that accumulates over time. Use cases include cleaning up after years of development work, resolving version conflicts between tools, removing unused binaries and dependencies, and generally optimizing system performance by eliminating unnecessary software debris.

SnapPoint targets developers working on macOS and Linux systems who need to maintain clean development environments. It's built as a single binary using Go programming language, requires no sudo privileges, and is available as open source software under the MIT license.
