Submarine Swaps vs Atomic swaps?

[MadGamer]

My current understanding is that they are different, atomic swaps are for off chain transactions while submarine are for the on chain transactions. Is that anywhere accurate?

If my above statement is indeed true then how come Submarine uses LN even the lightning network is actually off-chain? I'm a bit lost at this point.

Submarine swaps are more of an on-ramp to the Lightning Network. It allows someone to receive a payment on the Lightning Network without the payer using the Lightning Network. I believe it also works in the opposite direction too, i.e. the payer is using the Lightning Network but has to pay someone that doesn't use the Lightning Network.

I'm a bit lost in LN advancements but As there over was said submarine swaps are for normal bitcoin transactions ramped onto lightning and vice versa.

Atomic swaps I think are for exchanging different coins through the lightning network and with minimal costs and fees. As we know Litecoin Is developing on LN too so for example you could exchange your BTC for LTC without going out your channel and paying fee to a external exchange.

Please correct if wrong. I may be.

Interesting. Compared to LN and atomic swaps, is it going to take more time to be live? I've seen a video about it on /r/Bitcoin a couple of weeks ago and the only repository I found is this one: https://github.com/submarineswaps/swaps-service so It's hard to tell how active the development is.
