What works
- BYOK — no Cline subscription, just your API costs. Often cheaper than Cursor Pro for heavy users
- 61k GitHub stars — the largest open-source coding agent community
- Works in VS Code, JetBrains, and CLI — not locked to one IDE
- Fully model-agnostic: Claude, GPT, Gemini, local models via Ollama
- Full agentic loop — reads, plans, edits, runs commands, and iterates
- Open source and auditable — you can see exactly what it's doing
What doesn't
- BYOK setup adds friction vs Cursor or GitHub Copilot's one-subscription model
- No built-in usage dashboard — tracking costs across sessions requires external tooling
- Less polished UI than Cursor — it's a power-user tool, not a beginner IDE
- Enterprise support is newer and less mature than Cursor's
Stack AI

- Good UI for non-technical configuration
What doesn't
- Expensive at team scale ($199+/month)
- Limited flexibility for multi-step process automation
- Weaker for external-facing or trigger-based workflows
