SIGNET is a great option for testing Bitcoin stuff.
Mempool.space supports it out of the box, so does Sparrow Wallet, and getting signet coins seems to be quite hassle-free.

For mainnet, there are many publicly available Electrum servers. Not so for Signet -- but fortunately our friends at Mempool.space make their Signet API available free-of-charge:
Unfortunately in the last few days the Mempool Signet API worked unreliably (most requests just onnection reseted), but hey, it's a free service. I think it's just an intermittent issue.

In case you want to set up your own BitcoinCore + Electrs stack for Signet:
it needs about 8GB ram & 30GB disk, and does the initial download and indexing in less than half an hour. After that it lives happily in 4GB RAM as well (possibly less).
