Easy start/stop commands gives you 15 deterministic addresses of various key types with an abundance of Sui coins.
Test Automation
Faster edit/publish/test cycles with Rust and Python helpers
Proxy Server
Reduce timeout failures with automatic fallback to alternative RPC servers.
Version Matching
A distinct Sui client binary to each network (localnet, devnet, testnet, mainnet).
Workdir 'Containers'
Your apps, client, SDKs can re-use the same Sui local repo for faster build and single source consistency.
