The most known are: Exodus.io, Jaxx.io, coinomi.com. Some of these wallets are not open source but they do give you control over your private keys. There is Bit.ac (I believe there is scam accusation agains them), holytransaction as web wallets but they don't give you control over your private keys, If they ever decide to scam people and walk away, there is nothing you can do to get your funds back.
