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 (Kilo Auto — no credit card, no token limit on the free model tier). Paid plans run $20–$50/month for higher-tier model access. BYOK is the recommended path for serious use: connect your own API key to any of 500+ models via Kilo Gateway and pay providers directly. A solo developer on BYOK with Claude Sonnet typically lands at $30–$80/month in API costs depending on usage intensity. | Free tier with meaningful daily usage — generous enough for individual evaluation, no credit card required. Pro at $15/month unlocks unlimited Supercomplete and higher Cascade usage. Teams at ~$30/user/month adds collaboration and admin controls. Enterprise pricing on request for SSO, audit logs, and SOC 2 requirements. BYOK is available for serious-volume Cascade users wanting direct OpenAI API access. |
| Best for | Developers who want Claude Code-style agentic workflows but need JetBrains support, want model flexibility, or care about open-source licensing. Strong for teams running mixed IDE setups, cost-conscious solo developers, and anyone burned by Cursor's pricing changes who wants a free / BYOK alternative. | Developers who want the fastest IDE-native coding agent in 2026. Strong on Supercomplete autocomplete speed, large-codebase understanding, autonomous multi-file refactors, and goal-driven Flows that run without per-step approval. The right pick when your team works primarily in an editor and wants the agent to actively drive work rather than just suggest completions. |
| Not for | Non-technical users wanting a no-code interface. Teams already happy with Claude Code who don't need JetBrains or alternative models — Claude Code's polish is hard to beat when you only need Claude in VS Code. Builders who want the largest community and most mature documentation — Cline is upstream and more established. | Teams wanting terminal-first or headless agent workflows — Windsurf is IDE-bound. Claude Code or Aider are better for CLI-driven automation. Teams committed to JetBrains IDEs — Windsurf is VS Code-shaped and JetBrains support lags. Teams wanting model-agnostic flexibility — the OpenAI acquisition has clarified the model strategy but reduced near-term choice. |
Our verdict on Kilo Code
The best-priced agentic coding tool for developers who need JetBrains support or want to switch models mid-session. Apache 2.0, BYOK, multi-IDE. The right pick when Cursor's editor lock-in and Claude Code's model lock-in both bother you.
Full Kilo Code review →Our verdict on Windsurf
The fastest AI IDE for developers who want autonomous execution baked into the editor. Cascade and Flows handle multi-file refactors and goal-driven work end-to-end. OpenAI-acquired and actively developed. The right pick when speed and IDE-native autonomy matter more than terminal workflows.
Full Windsurf review →Kilo Code
What works
- VS Code, JetBrains, and CLI — broadest IDE coverage of any coding agent on this list
- 500+ models via Kilo Gateway — switch between Claude, GPT, Gemini, DeepSeek, local mid-session
- Apache-2.0 open source — auditable, self-hostable, no vendor lock-in
- Generous Kilo Auto free tier with no credit card required
- BYOK pricing means you pay model providers directly — no platform markup
- Slack, Discord, Telegram integrations for async agent workflows
- Cloud agents run 24/7 without your laptop open
What doesn't
- Documentation depth lags Cline (the upstream project) — newer, smaller community
- JetBrains plugin lags the VS Code experience in feature parity
- 500+ model menu adds decision overhead — most users would be better served by a curated default
- Cloud agent feature is newer and less proven at scale than CI/CD-based approaches
- Free tier model quality is fine for evaluation but BYOK is the right serious-use path
Windsurf
What works
- Fastest autocomplete in the category — Supercomplete predicts multi-line edits before you finish typing
- Cascade agent completes multi-file tasks autonomously end-to-end — less per-step approval friction than Cursor
- Flows layer handles complex goal-driven work with full autonomy inside the editor
- Strong large-codebase understanding — indexes your full repo for cross-file context
- Active development post-OpenAI acquisition — clear roadmap and integration with GPT-5+
- Free tier is genuinely usable — meaningful daily Cascade usage with no credit card
- Pro tier is $5/month cheaper than Cursor with comparable feature depth
- Strongest in-editor autonomous-agent UX of any AI IDE in 2026
What doesn't
- IDE-bound — no CLI or headless mode for server-side automation
- Less customisable than Claude Code for complex multi-step workflows
- JetBrains support lags significantly behind the VS Code experience
- VS Code extension ecosystem support slightly behind pure VS Code
- Model flexibility narrowing post-OpenAI acquisition — long-term roadmap favours GPT-5+
- Cascade autonomy can over-execute on ambiguous prompts; guard-rails are looser than Roo Code's mode-based approach
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, want model flexibility, or care about open-source licensing. strong for teams running mixed ide setups, cost-conscious solo developers, and anyone burned by cursor's pricing changes who wants a free / byok alternative.
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.
