What's the difference between coqui-ai/TTS and mozilla/TTS?

[ProgrammingLife]

Sorry for the stupid question but what's the difference between coqui-ai/TTS and mozilla/TTS? They are both install with the same command pip install TTS, they both have the same command-line syntax. Why then there are two different githubs for them?
Are they use the same models format?

Coqui-TTS is the successor to Mozilla-TTS: some time ago Mozilla stopped their STT and TTS project. Coqui.ai was founded by members of the former Mozilla team.

but now Coqui is dead, we need to wait for the next successor :(

@bernaferrari Why you say that. I am fresh here and I think it's the most active tts project,do I missing something？

Im a bit confused about this one as well. How do they both relate to https://commonvoice.mozilla.org/ then? If Mozilla abandoned the project, why are they still collecting data?

CommonVoice, Mozilla-TTS and Mozilla-STT were/are completely separate projects.
Mozilla has stopped working on TTS and STT but not on CommonVoice.
When Mozilla stopped working on TTS/STT, Coqui continued working on those projects, as domcross said.

CommonVoice: A publicly available voice dataset
TTS: A text to speech library
STT: A speech to text library

Another question on this front - the Mozilla team was previously making this an open-source system and "free to all". Is there any intention of having the better quality voices (i.e. studio ones) be free for users using API?
