Why these together

This is the 'I want to build with LLMs without paying OpenAI per token' stack. Ollama runs the models on your hardware (consumer GPU box or rented A100); Open WebUI is the ChatGPT-equivalent UI that talks to Ollama and lets non-technical teammates use the same models you're prototyping with; Continue is the IDE-side companion that wires the same Ollama endpoint into VS Code or JetBrains for completions and chat; LibreTranslate handles language pairs without round-tripping to DeepL. Cross-tool integration is one URL: every component points at `http://ollama:11434` and shares the loaded model. The honest cost call: this stack is hardware-bound, not VPS-bound — budget $1500 for a 24GB GPU box or $0.50/hr for a rented A100 when you actually need scale.
