RCH: Remote Compilation

RCH (Remote Compilation Helper) transparently intercepts cargo commands and routes them to powerful remote build servers. Your local machine stays responsive while heavy Rust compilations run elsewhere.

When running multiple AI agents that all trigger builds, your local CPU becomes a bottleneck. RCH solves this by syncing source to remote workers, building there, and streaming artifacts back.

RCH intercepts cargo commands via a Claude Code hook and offloads them to remote workers.

# Local: You run cargo build
cargo build --release
         ↓
# RCH Hook intercepts the command
         ↓
# Source synced to worker via rsync
         ↓
# Remote: Build runs on powerful server
         ↓
# Artifacts synced back to local machine

Get started with these essential commands.

RCH supports multiple remote workers with priority-based scheduling.

# Workers are stored in ~/.config/rch/workers.toml
[[workers]]
name = "build-server-1"
host = "ubuntu@192.168.1.100"
slots = 48
priority = 100
tags = ["fast", "baremetal"]
[[workers]]
name = "build-server-2"
host = "ubuntu@192.168.1.101"
slots = 16
priority = 80
tags = ["secondary"]

RCH includes comprehensive diagnostics to troubleshoot issues.

RCH configuration lives in ~/.config/rch/.

# View current config
rch config show
# Set default worker
rch config set default_worker=build-server-1
# Update RCH binaries on all workers
rch update --remote

RCH integrates seamlessly with other flywheel tools.
