I wouldn't call it third tier. If anything alongside opencode, and codex, its one of the "first tier" and the only non-VC-backed (at least before mario joined earendil (idk about earendil raising or not)
anyways. Pi is good. I dont need a telegram client for it, but this precisely show why pi is great, because its really easy to extend pi building plugins or modifying the source (yay, open source)
peace
So I tried Hermes, it had first-class telegram support, but then I never use it for coding and was asking it to delegate to codex / pi. There wasn't much I was gaining from hermes, so I stopped using it.
Then I started using Pi more and liked its extensability. Pi is the first software I have forked and developing to meet my needs. I genuinely love how extensible it is.
I was in the market to see any extensions that help me run Pi, and sure enough there were. One was from Mario himself, the creator of Pi (https://github.com/badlogic/pi-telegram), but it was a bridge instead of being a client itself. I need to start a chat in the TUI and then continue it in telegram. I didn't like that. Most others were same.
So I built my own!
I was confused.
