Jan pros and cons
Runs LLMs fully offline on your own hardware, so conversations stay private by default
Simple point-and-click model downloads from Hugging Face, no command line required
Genuinely open source under the permissive Apache-2.0 license
Exposes an OpenAI-compatible local API server (localhost:1337) for wiring into other apps
Local model quality depends heavily on your RAM and GPU; small models are far weaker than ChatGPT or Claude
Decent performance effectively needs 16GB+ RAM and ideally a supported GPU
Still maturing, with a fairly high open issue count and occasional rough edges
Piper pros and cons
Runs fully locally and offline, even on low-power devices like the Raspberry Pi
Large library of pre-trained voices across many languages
Multiple interfaces: CLI, HTTP server, and Python and C/C++ APIs
Proven in real use by Home Assistant and the NVDA screen reader
Maintainers are actively seeking new owners, a long-term support risk
GPL-3.0 license can complicate use in closed-source products
Voice quality trails top cloud and voice-cloning TTS engines
