In my experience, the “easier” niches are the ones that already expose public or semi-public APIs — things like fitness trackers, note-taking apps, simple social feeds, etc. They tend to have predictable request patterns and documented SDKs.
Where things get harder is financial, gaming, and streaming apps — a lot more client-side checks and custom obfuscation for obvious reasons.
For analysis I stick to legit tooling: platform dev tools, official SDK docs, and occasionally network debuggers if I'm testing traffic from my own device. Nothing fancy.
Bluesky’s ecosystem is a good example because the protocol is open by design, which makes exploring it educational rather than adversarial.
