Inner work that actually matters (meaning it makes a genuine and relevant impact) isn't going to be specific to whatever you mean by "indie" and "maker" and such. It may align with some particular philosophy that resonates with you; the nature of the "work" may fit what seems "right for you" within your particular context (not everyone needs, wants, or benefits from a psychedelic meltdown, or a ten year hardcore meditation retreat, or three months of sensory deprivation, or prayer, or splitting logs, or ...); but there is an "essential" core underlying the things that would actually matter. "Self-development and inner work" largely amounts to clarity/awareness. Most of us are completely clueless regarding the values that drive us, and fewer of us are aware we can choose them. We don't examine the goals that drive our choices and behaviors. We don't actively monitor and adjust our physiology. We allow thinking errors in their wide variety to accumulate and distort. We over-identify with thinking/feeling/states/etc. We don't examine the beliefs we have about ourselves and the world, and again, we don't realize we can change these. There are lots of ways to examine/inspect/alter the software you're running, installed by you, your family, your friends, your teachers, your culture, your country, your experiences, your environment, your everything else. Find one that clicks and go for it. The idea that this will be somehow unique to "indie and maker world" is, ah, "not very helpful". Personally, I mostly use hypnosis/self-hypnosis/some forms of meditation/inquiry and the like, but that's what suits my inclinations. (And I'm a hypnotist, so of course that's what I prefer.) I got interested in that when I was a wee teen and it's been a very fine tool. But your mileage varies because you're driving a different vehicle.
