<p>There is chainquery which allows you to try some cli commands online. Not all commands are available, but it's a good start to get your feet wet. <a href="https://chainquery.com/bitcoin-api" rel="noreferrer">https://chainquery.com/bitcoin-api</a></p>

<p>Currently I'm reading a great book <a href="https://www.bitcoinbook.info/" rel="nofollow noreferrer">Mastering Bitcoin</a> and the author on his first articles suggests to the reader build from the source <a href="https://github.com/bitcoin/bitcoin.git" rel="nofollow noreferrer">Bitcoin Core</a> environment and down load the whole blockchain ledger (about 60Gb) to my local storage to be able perform common queries. But it's to long way for me.</p>

<p>So, is there any where on Internet already exist an online <code>bitcoin-cli</code> command line tool where I could practice?</p>

<p>Thank you!</p>

# Online bitcoin tools playground?

(Asked by: username_0 on 2016-11-23)

Currently I'm reading a great book [Mastering Bitcoin](https://www.bitcoinbook.info/) and the author on his first articles suggests to the reader build from the source [Bitcoin Core](https://github.com/bitcoin/bitcoin.git) environment and down load the whole blockchain ledger (about 60Gb) to my local storage to be able perform common queries. But it's to long way for me.

So, is there any where on Internet already exist an online `bitcoin-cli` command line tool where I could practice?

Thank you!
