Open-source blockchain explorer for regtest mode

I’m trying to find an open-source Bitcoin blockchain explorer that will work in regtest mode, so I can more easily inspect the blockchain, see what transactions are getting processed and included, etc.

I found the following ones, but all of them seem to have issues:

  • blockcypher is “not easily compatible with running your own version locally, and this is no longer recommended (except for expert users).”
  • bitcoinchain is not open-source AFAICT.
  • Bitcore’s insight-ui [1], [2], [3] does not work with bitcoind AFAICT.
  • toshi does not work with bitcoind AFAICT. Not sure how to set it up in regtest mode to connect to another bitcoind full node.
  • bitcoin-abe does not seem to support regtest mode, though it could be as easy as adding a new Abe/Chain/Regtest.py file.
  • blockchain.info: can’t really tell if the My-Wallet-V3-* repos [1], [2] are for the block explorer website or for the wallet-management side of the website.

So, any suggestions for an easy-to-setup blockchain explorer that works with a local bitcoind node ?
