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.

Usage

Website

Browse metrics and charts at bitview.space, no signup required.

API

curl https://bitview.space/api/mempool/price

Query metrics and blockchain data in JSON or CSV.

Documentation · JavaScript · Python · Rust · llms.txt · LLM-friendly schema

Self-host

cargo install --locked brk_cli && brk

Run your own website and API. All you need is Bitcoin Core.

Note: BRK uses sparse files. Tools like ls -l or Finder report the logical file size (>1 TB), not actual disk usage (~350 GB). Use du -sh to see real usage.

Guide · Professional hosting

Library

cargo add brk
