Here is my list of 44 (mostly) reviewed Bitcoin forks. This list is not comprehensive, I am not adding anymore forks that I newly learned about that very clearly have just a website (and maybe an old source code) and never really took off, it would be just a waste of my time.
Feel free to suggest a bugfix, addition or any other improvement.
The difference between this list and most of the other lists is that I personally compile the source code, run the software, sync or import all the shared pre-fork blockchain data (using the method I described here, if possible - almost always is), sync-up the blockchain, replace wallet.dat with my Bitcoin Core's encrypted wallet.dat, zap/rescan the wallet and verify that my balances are properly present. Since I never import any private key (and so far never made a since transaction on any of these new forks, thus never unencrypted and revealed my keys) even if the software is evil and would like to babble out the private keys it can't. I am only interested in forks with full-node source code based on Bitcoin Core. If all this checks out I deem the fork as "seems to be working". If I cannot readily find the value of given fork then the value is "unknown", if the amount of forked coins corresponding to 1 BTC is of value lesser than 1% of 1 BTC then the value is "next to zero".
(Last update: June 30th, 2018)
Total number of reviewed Bitcoin forks: 44
of which
- seem to be working: 20 (2806 GB) +1 fork of Bitcoin Cash (143 GB)
- somewhat working: 1
- first worked then stopped: 2 (328 GB)
- seem to have no nodes: 1
- haven't published full-node source code based on Bitcoin Core: 11
- seem like a waste of my resources to compile/sync/test (sorry): 3
- seem abandoned: 1
- don't seem to exist (anymore): 5
(Blockchains deduplication statistics: 20 BTC forks + 1 BCH fork + BTC + BCH + BTG + BTX = 3.41 TB, deduplicated down to 940 GB, savings rate 73%)

Honorable mentions
Stellar Lumen (XLM)
- https://www.stellar.org/
- bitcoin holders could have claimed free lumens until August 27th, 2017
Byteball Bytes (GBYTE)
- https://byteball.org/
- bitcoin holders (as well as byteball holders themselves) were getting free bytes and blackbytes in distribution rounds since December 25th, 2016, distributed 64.5% of the total supply
- the distribution was cut short suddenly and without any prior announcement => loss of credibility
Bitcore (BTX)
- https://bitcore.cc/
- originally the bitcoin holders received free coins in two rounds and then all the bitcore holders have been receiving weekly airdrops for several months
Bitcoin Hush (BTCH)
- http://btchush.org/
- bitcoin holders can claim BTCH in 1:1 ratio
- "BTCH takes the value from four different blockchains (HUSH, SUPERNET, DEX, BTC), and then dumps it onto a host chain Komodo (KMD). It does not fork from KMD, nor does it fork from BTC or HUSH. It is technically NOT A FORK, but a merged airdrop."
