I recently won a contest, and I won 750$ funds in my Vultr account
Applause!
So I am willing to use my vultr funds to contribute a dozen block explorers for a whole year.
Very public-spirited of you ...
$62.50 will get you a reasonably capable machine.
If I were you, I'd be looking at
RPC-ACE (php) or one of the open source explorers based on node.js such as
Iquidus that read the metadata via the RPC port (with the attendant caveats about inspecting the coin source before taking the RPC output on trust, there have been examples where crooked devs have hacked their coin's RPC code in order to mask a hidden premine).
Abe, the original Python-implemented explorer actually reads the metadata direct from the blockchain and stores it into an RDBMS, so is correspondingly more challenging to set up but has the advantage that it is very difficult, even impossible to fool it into reporting false values. It has fewer features than the more recent explorers based on node.js.
This might also help:
