Lantern is a local Solana RPC cache powered by FluxRPC data. It can serve selected account-state reads locally for very low latency while forwarding unsupported or uncached requests upstream.
Lantern - Local Solana RPC
Lantern: The fastest local Solana RPC. Run your own high-performance Solana node with minimal latency. Available for macOS, Linux, and Docker.
Local cache for frequent Solana account reads
Lantern streams updates for the programs you configure, keeps selected account state local, and answers supported requests from that local cache when possible.
Built for low-latency and high-throughput workloads
FluxRPC docs describe Lantern response times around 0.1-0.25ms for common cached reads and local throughput above 10,000 requests per second in test conditions.
Uses FluxRPC as its data source
Lantern still relies on FluxRPC for upstream data and synchronization. That means your cost model remains tied to FluxRPC bandwidth while cached reads can reduce repeated upstream calls.
