I know you won't believe this, but you don't need any of these GTOS (giant towers of shit) to write & ship code. "Replace one GTOS with another" is a horizontal move to still using a GTOS.
You can just install the dev tools you need, write code & libraries yourself, or maybe download one. If you don't go crazy with the libraries, you can even tell a team "here's the 2 or 3 things you need" and everyone does it themselves. I know Make is scary, with the mandatory tabs, but you can also just compile with a shell script.
Deployment is packing it up in a zip and unzipping it on your server.
