S3

An MCP server and CLI for shared notebooks for agents, with pull/commit workflows, durable S3 storage, and text-based conflict handling.

ZeroFS turns S3-compatible buckets into a primary storage layer with POSIX access over NFS and 9P, or raw block devices over NBD. It includes encryption, compression, caching, checkpoints, read replicas, and a web UI, with public CI and recorded demos backing the project.

A serverless document database that runs inside request handlers and stores state in S3/R2. The repo shows a small TypeScript API, quick-start flow, local dev support, and example scaffolds for app integration.

WalTier is a Rust embeddable tiered write-ahead log coordinated through S3 conditional writes. It provides durable ordered logging, compaction, replicas, and local disk or memory stores for development and testing.

Sana is an object-storage-native search database for vectors, full-text search, and attribute filters. The repo describes durability, indexing, backends, operations, and quick-start commands for running the service or demo.

A Rust library for sparse byte-range caching and async read coalescing on immutable objects, with support for range semantics, eviction, and optional read-through caching.

CLI tool for migrating Claude Code sessions across machines and backing them up to S3-compatible storage.
