Anvil: Next-Generation Object Storage Built for AI
S3-compatible object storage written in Rust, designed from the ground up for AI model hosting, multi-tenant applications, and high-performance workloads. Deploy in minutes, not hours.
Why Choose Anvil?
🦀 Built in Rust for Performance
Memory-safe, blazing fast, and resource-efficient. Anvil leverages Rust's zero-cost abstractions and fearless concurrency to deliver performance that outpaces traditional Go-based solutions while using less memory.
🪣 True S3 Compatibility
Drop-in replacement for MinIO with full S3 API compatibility. Use your existing AWS CLI, SDKs, and tools without modification. Seamlessly integrate with your current infrastructure.
🧠 Optimized for AI Workloads
Purpose-built for hosting open-weight models and large binary files. Efficient handling of multi-GB model files with optimized read patterns for ML inference pipelines and training workloads.
⚡ gRPC API Built-In
Native gRPC support alongside S3 HTTP API. Get better performance for internal service communication with binary protocols and bidirectional streaming—something MinIO doesn't offer.
👥 Multi-Tenant by Design
First-class multi-tenancy with isolated namespaces, per-tenant policies, and granular access control. Perfect for SaaS platforms, managed services, or departmental isolation within enterprises.
📜 Apache 2.0 Licensed
Truly open source with a permissive license. Unlike MinIO's AGPLv3, you can modify, distribute, and use Anvil in commercial products without viral license restrictions.
