Bitcoin Research Kit
"Shout out to Bitcoin Research Kit. [...] Couldn't recommend them highly enough." — James Check (CheckOnChain), What Bitcoin Did #1000
Open-source, self-hostable on-chain analytics for Bitcoin. Block explorer, address index, and thousands of metrics, everything computed from your node, even the price.
Similar to Glassnode + mempool.space + electrs + UTXO Oracle in a single package.
Bitview is a free hosted instance of BRK.
Data
Zero external dependencies. BRK needs only a Bitcoin Core node. Historical prices are built in, live price from your mempool. Every metric is computed locally from your own copy of the blockchain. Your node, your data.
Blockchain: Blocks, transactions, addresses, UTXOs.
Metrics: Supply distributions, holder cohorts, network activity, fee markets, mining, and market indicators (realized cap, MVRV, SOPR, NVT).
Indexes: Date, height, halving epoch, address type, UTXO age.
Mempool: Fee estimation, projected blocks, unconfirmed transactions.
