Show HN: Zs3 – S3 server in ~1K lines of Zig, 250KB binary, zero dependencies

3 months ago

S3-compatible storage implemented in ~1.4K lines of Zig with zero dependencies.
Supports basic S3 operations: PUT, GET, DELETE, LIST with full AWS SigV4 authentication.
Comparison with RustFS and MinIO shows significant advantages in lines of code, binary size, and RAM usage.
Features include multipart uploads, range requests, versioning, lifecycle policies, and pre-signed URLs.
Designed for local development, CI artifact storage, self-hosted backups, and learning S3 internals.
Performance benchmarks show zs3 outperforming RustFS by up to 537x in operations like LIST.
Easy to set up with simple commands for building and running the server.
Supports integration with any S3 SDK, demonstrated with boto3 Python example.
Security features include input validation, request size limits, and no external network calls.
TLS not included; recommends using a reverse proxy like nginx or caddy for HTTPS.
