DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for Cua, the case for Open Interpreter, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick Cua
96.1 / 100- 30,045+ GitHub stars under MIT providing near-native (95% speed) macOS and Linux VMs via Apple Virtualization.framework (Lume)
- Full host filesystem and credential isolation so autonomous Computer-Use 2.0 agents cannot damage the host machine
- Unified Computer-Use SDK compatible with UI-TARS, Anthropic Claude Computer Use, OmniParser, and OpenAI CUA
When to Pick Open Interpreter
96.5 / 100- 68,642+ GitHub stars under MIT as the most popular open-source natural-language terminal and desktop coding agent
- Executes Python, Bash, AppleScript, and GUI actions locally with zero VM image download required
- Supports local Ollama, Llamafile, Kimi, GLM, and frontier BYOK APIs via `interpreter --os`
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.
