RPC Plane

Solana RPC proxy with intelligent multi-provider routing, automatic failover, and slot-aware health scoring. A single binary that sits between your app and your RPC providers.

Your App → http://localhost:9400 → [Helius / QuickNode / Triton]

Quick start

# Download and install
curl -sSf https://rpcplane.dev/install.sh | sh

# Generate a starter config
rpc-plane init

# Add your provider URLs and start the proxy
rpc-plane run

Point your app at http://localhost:9400. No other changes needed.

What it does

  • Routes reads to the healthiest provider based on latency, error rate, and slot freshness
  • Broadcasts writes (sendTransaction) to all healthy providers simultaneously — maximises landing probability
  • Circuit breaker per provider: opens on failure, probes for recovery, resumes automatically
  • Slot tracker: detects slot drift, deprioritises stale nodes
  • Auto-retry on transient errors (429, 503, timeout) — tries the next-best provider
  • Hot reload: edit the config file, changes apply within 2 seconds, no restart needed
  • Prometheus metrics on :9401/metrics
  • Zero infrastructure: one binary, one config file, no databases, no Redis
