hanzoai/s3 was an AGPL-3.0 MinIO fork whose network-copyleft blocks embedding
and reselling as a managed service. Replace it wholesale with a fork of
SeaweedFS (github.com/seaweedfs/seaweedfs, Apache-2.0, Go) which ships a
built-in S3 gateway + Filer.
- License: AGPL-3.0 -> Apache-2.0 (upstream LICENSE kept verbatim, incl.
"Copyright 2025 Chris Lu"); NOTICE added crediting SeaweedFS. No AGPL/BUSL/
SSPL/GPL or enterprise ("ee") files remain.
- Module: go.mod path set to github.com/hanzoai/s3 with a self-replace
(replace github.com/seaweedfs/seaweedfs => ./) so the ~1800 internal Go files
keep their upstream import paths with zero churn. Internal identifiers and
import paths are intentionally NOT renamed.
- CLI rebrand: the binary is built as `s3` (was `weed`); root usage, per-command
help/usage/flag strings, shell autocomplete program name, and the product name
in CLI output now read "Hanzo S3" / `s3`. Users never see `weed`.
(e.g. `s3 server`, `s3 filer`, `s3 master`, `s3 volume`, `s3 s3`, `s3 mount`.)
- Build: `make` (or `go build -o s3 ./weed`) builds the `s3` binary green;
`cmd/weed-db` and `cmd/weed-sql` also build; `go vet ./weed/command/` clean.
- README/LLM.md rewritten for Hanzo S3; AGENTS.md/CLAUDE.md symlinks preserved.
- Dropped a 33MB prebuilt Mach-O `stress` binary upstream had committed; `.gitignore`
updated to ignore the `s3` build output.
Hanzo S3
Hanzo S3 is Hanzo AI's S3-compatible object store: a fast, simple, scalable distributed storage system with a built-in S3 gateway, Filer, and FUSE mount.
It is an Apache-2.0 fork of SeaweedFS.
The only differences from upstream are branding: the command-line binary is
shipped as s3 (instead of weed), and user-facing help/branding reads
"Hanzo S3". All internal Go packages keep their upstream import paths, so the
fork tracks SeaweedFS with minimal divergence.
Why this exists
The previous hanzoai/s3 was an AGPL-3.0 MinIO fork. AGPL's network-copyleft
makes it impractical to embed and resell as part of a managed offering.
SeaweedFS is Apache-2.0, so Hanzo S3 can be embedded, modified, and offered as
a service without copyleft obligations.
Build
Requires Go 1.25+.
make # builds ./s3 at the repo root
# or
go build -o s3 ./weed
Full build with optional backends (elastic, sqlite, tikv, ydb, tarantool, rclone, gocdk):
make full_install
Usage
The binary is s3. Common commands:
s3 server -s3 -filer -dir=/data # all-in-one: master + volume + filer + S3 gateway
s3 master # start a master server
s3 volume -dir=/data -max=5 # start a volume server
s3 filer -master=localhost:9333 # start the Filer
s3 s3 -filer=localhost:8888 # start the S3 API gateway
s3 mount -filer=localhost:8888 -dir=/mnt/s3 # FUSE mount
s3 mini # single-process setup for S3 beginners / dev
s3 -h # full command list
s3 help <command> # help for a specific command
s3 version
The S3 gateway speaks the AWS S3 API; point any S3 SDK or aws s3 client at it.
Documentation
Hanzo S3 is API- and behavior-compatible with upstream SeaweedFS, so the upstream documentation applies directly:
- SeaweedFS Wiki: https://github.com/seaweedfs/seaweedfs/wiki
- S3 API reference: https://github.com/seaweedfs/seaweedfs/wiki/Amazon-S3-API
Wherever the upstream docs say weed, run s3 instead.
