Provision encrypted storage backed by R2. Your encryption key never leaves your machine.

tinymount create my-vol
2

Mount

FUSE mount with full POSIX semantics. Works on Linux and macOS.

tinymount mount my-vol ~/data

Use

Read, write, chmod, symlink. It's a real filesystem. Stream TB-scale datasets.

cp model.pt ~/data/

Why tinymount?

01

Zero egress fees

Cloudflare R2 charges $0 for data transfer out. Download your 500GB dataset as many times as you want.

02

Real POSIX semantics

Not a leaky S3 abstraction. JuiceFS provides actual filesystem behavior—chmod, symlinks, atomic renames.

03

Client-side encryption

Your password derives an AES-256 key locally. We store ciphertext only. We cannot read your files.

04

One command setup

No IAM roles, no bucket policies, no credential files. Create a volume and mount it in seconds.

Built on proven tech

We didn't reinvent the wheel. tinymount combines battle-tested open source projects into a seamless experience.

Built for

ML

Training data pipelines

Mount datasets on GPU instances. Stream terabytes from R2 without paying egress. Ephemeral volumes auto-delete when you're done.

Research

Lab data sharing

Share datasets across lab machines without copying. Same volume, multiple mounts. Zero egress means zero surprise bills.

CI/CD

Build caches

Persistent caches that survive ephemeral runners. Mount, build, unmount. Faster than downloading from S3 every time.

Backup

Encrypted archives

rsync to the cloud with zero-knowledge encryption. We store ciphertext. You keep the key. Restore anywhere.
