Infinitely scaleable

Use unlimited namespaces for isolation between tenants and unbounded horizontal scalability.

% loonfs

Read and write to your LoonFS durable workspace.

Filesystem operations

ls List a directory. stat Describe one visible path or inode. cat Print a file's content to stdout. get Download a file or directory tree. put Upload a file or directory tree. mkdir Create a directory. rm Delete a file or directory. mv Move or rename a path. cp Copy a file or directory tree.

Transactional and durable

LoonFS is built around correctness, with ACID guarantees for all familiar filesystem operations.

Collaborative for humans and agents

Version history, copy-on-write forks, and configurable retention; LoonFS provides the primitives for collaboration at scale.

Performance

Built for scale

Max throughput currently observed in production.

Throughput measured against each provider's API on the same benchmark suite. Higher is better.

The alternative providers do not primarily serve the same embedded use case, but we have chosen them to illustrate performance over comparable feature sets.

Developer experience

Interfaces for easy embedding and operation

SDKs

Typed clients for TypeScript, Python, and Go to seamlessly embed LoonFS in your platform.

Admin CLI

Monitor and maintain LoonFS directly from the terminal, or use the CLI interface to automate administrative namespace operations.

Pricing

LoonFS has a minimum usage of $16/month.

Frequently asked questions

How is LoonFS different from S3?

LoonFS is a filesystem layer over object storage, creating an indexed, transactional, and versioned filesystem from object-storage primitives. S3 is a better choice when your data model treats objects as values with keys. LoonFS is a better choice when you need files with paths, folders, stable IDs, revisions, transactional updates, and a consistent filesystem history.

How is LoonFS different from Git?

Git is version control for code-first projects; LoonFS is a transactional, versioned filesystem for platforms. Git is the better choice when clients treat the entire filesystem as a single atomic project. LoonFS is the better choice for applications that need to upload, organize, search, update, and restore files in a shared workspace.

How is LoonFS different from Dropbox, Box, or Google Drive?

At the feature level, LoonFS has a lot in common with cloud drives. The key differences are in the deployment model and scalability: LoonFS is built for embedding (in other words, it's API-first), so it can run as a native part of your own platform. LoonFS is also built for agent scale and can handle orders of magnitude more operations per second than these other platforms.

Can I bring my own object storage bucket?

Yes. Though LoonFS provides the object storage bucket by default, you may configure your own bucket from any supported provider.
