Hey Stackers,

I made this simple CLI tool in one day Bun + TS for fun. It’s called ChainChirp and it spits out live Bitcoin + Lightning stats right in the terminal—price, mempool fees, block height, etc.

Examples:

chainchirp price       # quick shot of the price
chainchirp fees        # see current feerate

No API keys, just public endpoints with some caching so you don’t 429 yourself. I tried to give it a nice ux with unicode icons, chalk colours, and ora spinners.

It’s free and open-source, get it here: https://www.npmjs.com/package/chainchirp
