Head-to-head
Kilo Code vs Windsurf.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Both are in our coding agent category — direct competitors.
| Kilo Code | Windsurf | |
|---|---|---|
| Rating | 4.0 / 5 | 4.5 / 5 |
| Category | Coding Agent | Coding Agent |
| Tech level | developer | developer |
| Open source | Yes | No |
| Pricing | Free tier available (Kilo Auto, no credit card required). Paid plans for higher usage. BYOK supported — connect your own API key to any of 500+ models via Kilo Gateway. | Free tier (limited). Pro ~$15/month. Teams ~$30/user/month. |
| Best for | Developers who want Claude Code-style agentic workflows but need JetBrains support or broader model access. The multi-IDE story is the clearest differentiator from Claude Code and Cursor. | Developers who want the fastest IDE-native coding agent — strong on autocomplete speed, large codebase understanding, and autonomous multi-file refactors without leaving the editor. |
| Not for | Non-technical users wanting a no-code interface. Teams fully happy with Claude Code who don't need JetBrains or alternative model providers. | Teams wanting terminal-first or headless agent workflows. Windsurf is IDE-bound — Claude Code or Aider are better for CLI-driven automation. |
Our verdict on Kilo Code
Open-source coding agent for VS Code, JetBrains, and CLI. 500+ models via Kilo Gateway. #2 on OpenRouter this week. Trusted at Meta, Amazon, and Airbnb.

What works
- VS Code, JetBrains, and CLI — the broadest IDE coverage of any coding agent on this list
- 500+ models via Kilo Gateway — not locked to Anthropic or OpenAI
- Cloud agents run 24/7 without your laptop open
- Apache-2.0 open source — auditable and self-hostable
- Slack, Discord, and Telegram integrations for async agent workflows
- Free tier with no credit card required
What doesn't
- Newer than Cursor or Cline — smaller community, less battle-tested documentation
- 500+ model support adds decision overhead — more choices don't always mean better outcomes
- Cloud agent feature is newer and less proven at scale than established CI/CD-based approaches
- JetBrains support, while a key differentiator, lags VS Code in feature parity
Windsurf
What works
- Fastest autocomplete in the category — Supercomplete predicts before you finish
- Cascade agent completes multi-file tasks autonomously end-to-end
- Flows layer handles complex goals with full autonomy
- Strong large-codebase understanding — indexes your full repo
- Active development post-OpenAI acquisition
- Free tier is genuinely usable — low friction to evaluate
What doesn't
- IDE-bound — no CLI or headless mode for server-side automation
- Less customisable than Claude Code for complex multi-step workflows
- VS Code extension ecosystem support slightly behind pure VS Code
- OpenAI acquisition raises questions about long-term model flexibility
Which to pick
We'd default to Windsurf (4.5/5 vs 4.0/5) for most builders. Pick Kilo Code if you fit its best-for case specifically: developers who want claude code-style agentic workflows but need jetbrains support or broader model access. the multi-ide story is the clearest differentiator from claude code and cursor.
Honest middle: most serious operators end up using more than one tool. If you're early in your AI agent journey, our five-question picker recommends a starting platform from your specific situation.
