Registry Explorer: Interactively Explore Docker Images

2025-09-13

Registry Explorer is a powerful tool that lets you interactively explore the contents of Docker images, even drilling down into the filesystem. Running on Google Cloud Run and using google/go-containerregistry, it cleverly minimizes costs and registry traffic. Layers are downloaded and indexed only once, with subsequent access using efficient indexing and range requests. This saves bandwidth and reduces load on the registry. The project is open-source and sponsored by Docker.
