> "Shout out to Bitcoin Research Kit. [...] Couldn't recommend them highly enough."

Open-source Bitcoin data toolkit that can parse blocks, index the chain, compute metrics, serve data and render it, all from a Bitcoin Core node. It combines what [Glassnode](https://glassnode.com) and [mempool.space](https://mempool.space) do separately into a single self-hostable package, with a built-in price oracle inspired by [UTXO Oracle](https://utxo.live/oracle/).

[Bitview](https://bitview.space) is the official free hosted instance of BRK.

## Data

**Zero external dependencies.** BRK needs only a Bitcoin Core node. 8,000+ metrics across 15 time resolutions, all computed locally from your own copy of the blockchain. Historical prices are built in, live price from your mempool. 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](https://bitview.space), no signup required.

### API

```bash

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

```

Query metrics and blockchain data in JSON or CSV. No rate limit.

[Documentation](https://bitview.space/api) · [JavaScript](https://www.npmjs.com/package/brk-client) · [Python](https://pypi.org/project/brk-client) · [Rust](https://crates.io/crates/brk_client) · [llms.txt](https://bitview.space/llms.txt) · [LLM-friendly schema](https://bitview.space/api.json)

### Self-host

```bash

cargo install --locked brk_cli && brk

```

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

> **Note:** BRK uses [sparse files](https://en.wikipedia.org/wiki/Sparse_file). 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](https://github.com/bitcoinresearchkit/brk/blob/main/crates/brk_cli/README.md) · [Professional hosting](./PROFESSIONAL_HOSTING.md)

### Library

```bash

cargo add brk

```

Build custom applications in Rust. Use the full stack or individual components (parser, indexer, computer, server).
