I use suckless terminal because the entire terminal is 4888 lines of C (including comments). Builds immediately. Starts immediately. Does everything I need it to do.

Have several running; resident set size between 10MB and 19MB.

Start with the person that is instrumental in this - Mitchell Hashimoto - you probably use products built on top of or with his tooling somewhere in your daily life already without knowing it. https://mitchellh.com/

I suspect you're getting down voted on this as it feels like this is a failure to educate yourself on something that feels like it should be relatively easy to do so in less time than it took to type your message.

Wait until it is packaged for your distro. It should be vetted then.

If on Mac/Win, you should be used to trusting notarized apps after a cooldown period.

any idea why people downvoting a legit question? what's wrong with them ?

Reply and then downvote, but silently downvoting ? not a real men, hiding behind their keyboard :)
