DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for OpenHands, the case for Aider, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick OpenHands
96.3 / 100- 46k+ GitHub stars with full Docker microVM sandboxing for untrusted code execution
- Multi-agent architecture supports autonomous browser interaction and Jupyter notebook execution
- 72.0% SWE-bench Verified resolution loop with autonomous terminal bash debugging
When to Pick Aider
98.0 / 100- 98.0/100 benchmark score with sub-1.2s local startup and zero daemon overhead
- Tree-sitter repository map fits 100k+ LOC context in under 8k tokens with 44% lower spend
- Deterministic, reviewable git commits with automated syntax check and git-diff verification
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.
