DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Ollama, the case for llama.cpp, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Ollama
96.2 / 100- 114k+ GitHub stars; 1-command `ollama run` pulls, caches, and serves GGUF models with zero flags
- Automatic model lifecycle unloading and clean OpenAI/Anthropic-compatible localhost endpoints
- Turnkey integration with Cursor, Cline, Continue, Open WebUI, and Raycast
When to Pick llama.cpp
93.5 / 100- 131.3k+ GitHub stars; the upstream C/C++ GGUF engine with zero runtime wrapper overhead
- Native `llama-server` supports parallel request slots, speculative decoding, and grammar constraints
- 8-14% lower VRAM footprint and faster time-to-first-token on Apple Silicon Metal and CUDA
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
