Cline
Open-source agentic VS Code extension — bring your own API key, plan-then-act flow, very transparent.
Best for
- Engineers who want a transparent agentic flow with explicit confirmation steps
- Teams that need to run on their own API keys for privacy or cost control
- Workflows mixing local and frontier models (switch via dropdown)
Weak at
- Simplest day-to-day completion — Cursor's Tab is faster
- Discoverability — the deep settings surface takes time to learn
Pricing
| Tier | Price | Notes |
|---|---|---|
| Solo (free) | $0 / month | Software is free; you pay model API costs (typically $15–120/mo) |
| Teams | Free → $20 / seat | Free now, $20/seat/month from Q2 2026 — first 10 seats permanently free |
| Model API costs | Variable / usage | Anthropic, OpenAI, Gemini, Bedrock, Azure, OpenRouter, or local Ollama |
What it is
Cline is an open-source AI coding agent that runs as a VS Code extension (with JetBrains and a preview CLI also available). It scaffolds whole features across files, runs test suites, debugs failures, and iterates — under explicit user control via Plan and Act modes.
What it does well
The Plan/Act split is unusual and useful: Plan mode is non-destructive reasoning that’s much cheaper than Act mode, so you can think out loud with the model before authorizing changes. Provider support is unmatched — 30+ model providers as of 2026, from frontier APIs to local Ollama.
For BYOK workflows where the user wants control over data and cost, Cline is the leading option.
Where it falls short
Tab-style completion is not its strength; it’s an agent first. Settings and configuration surface is deep, which means more power but also a steeper learning curve than Cursor or Copilot.
Verdict
Best free agentic option for VS Code users who already pay for an API key. Plan/Act mode and broad provider support make it especially good for cost-conscious or privacy-sensitive teams. Less polished than commercial competitors, but you can read the source.
