# aider vs private-gpt

aider and private-gpt share 3 technologies: FastAPI, nltk, and llama-index-core. Both are written in Python.

- [Aider-AI/aider](https://seerepo.com/r/Aider-AI/aider): aider is AI pair programming in your terminal
- [zylon-ai/private-gpt](https://seerepo.com/r/zylon-ai/private-gpt): Complete API layer for private AI applications on local models: RAG, skills, tools, MCP, text-to-sql, and more. Works with any OpenAI-compatible inference server.
