• https://raw.githubusercontent.com/juicedata/juicefs/main/LICENSE recorded 2026-09-30

  LICENSE file is the Apache-2.0 text: "Apache License" and "Version 2.0, January 2004" and "TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION".

• https://raw.githubusercontent.com/juicedata/juicefs/main/README.md recorded 2026-09-30

  README says JuiceFS is a file system "released under Apache License 2.0" and closes with "JuiceFS is open-sourced under Apache License 2.0"; searched the body for enterprise, paid tier, license key and pricing: none.

JuiceFS ships as a Go binary and a CSI driver rather than through a package registry this map can measure, leaving GitHub stars as the closest available adoption signal. A juicefs package exists on PyPI, but it is an unofficial third-party client published from another organization's repository, not JuiceFS's own distribution channel, so its downloads are not counted.

JuiceFS is a complete, distributed POSIX file system over object storage, with a pluggable metadata engine, caching, clones and quotas, and it is a storage system rather than a search index. That keeps it one step below Vespa, which covers retrieval as well as storage.

• https://juicefs.com/docs/community/guide/cache/ recorded 2026-09-30

  Cache page states "The use of caching technology can significantly reduce the latency of storage operations".

• https://juicefs.com/docs/community/guide/clone/ recorded 2026-09-30

  Clone page states "Cloning specific data does not involve copying the actual object storage data but only copies metadata."

• https://juicefs.com/docs/community/guide/quota/ recorded 2026-09-30

  Storage quota page states "JuiceFS supports both total file system quota and subdirectory quota".

  Introduction page describes JuiceFS as "an open-source, high-performance distributed file system designed for the cloud".

• https://raw.githubusercontent.com/juicedata/juicefs/main/README.md recorded 2026-09-30

  README says the S3 Gateway "provides an S3-compatible interface", a CSI driver "is provided for easily using JuiceFS in Kubernetes", and metadata "can be persisted in various compatible database engines such as Redis, MySQL, and TiKV".
