I search for a online block explorer that has a raw view for blocks.

Preferably in the getblocks.bin binary format as hex string.

It would also be great if it had testnet network.

A bonus would be if the explorer is open source somewhere.

Edit:

[For bitcoin its something like this][1] In [json][2] and here in [hex][3].

I am searching for the ["block_complete_entry"][4] data of a single block, there should be also pruned tx data in there.

  {
    blobdata block;
    std::vector<blobdata> txs;
    BEGIN_KV_SERIALIZE_MAP()
      KV_SERIALIZE(block)
      KV_SERIALIZE(txs)
    END_KV_SERIALIZE_MAP()
  };```
