ChatGPT is synonymous with AI chat, but data being sent to OpenAI servers and API costs are concerns for some. devpick lists OSS alternatives that run locally without sending data externally.
- Local LLM execution via Ollama keeping all data on your machine
- ChatGPT-like UI with Open WebUI providing an equivalent conversational interface
- RAG support in AnythingLLM for building knowledge bases from internal documents
- Visual workflows in Flowise for building AI apps with drag-and-drop
- Multi-model switching between OpenAI, Anthropic, Ollama, and other LLMs
For local LLM execution choose Ollama plus Open WebUI, for internal document RAG choose AnythingLLM, and for AI workflow building choose Flowise.
