DeltaGlider Proxy documentation

DeltaGlider is an S3 proxy that sits between your applications and S3-compatible storage. It stores similar files as small binary diffs of each other instead of full copies, and you don't need to change your client code. The proxy is source-available (BUSL-1.1) and free up to 15 TB.

Using an AI assistant? Give it llms.txt (an index of every page) or llms-full.txt (all pages in one file). Every page is also plain markdown at its URL plus .md, for example /docs/reference/configuration.md.
