Stich is SaaS only. That by nature makes it suitable for some uses, and unsuitable for others (like when you have a provision that your data can't leave your network or when you are in a company where adding a new vendor isn't a quick process.
Meltano and Pipelinewise are open source projects that someone built for themselves but are sharing. You can just start playing with it and change the code or whatever, but there's no support to pay for.
For example where I'm standing the best one would be "Stitch I can self-host for free for a PoC and then eventually engage vendor about a support contract while still self-hosting it for security reasons" but there doesn't seem to be anything like it.
