Kilo Code started as an open-source fork of Roo Code, which was itself a fork of Cline. That lineage matters because it tells you something about the philosophy: this is a tool built by engineers for engineers, with a preference for transparency over polish. The company behind it is co-founded by Sid Sijbrandij, GitLab’s former CEO, and positioned from the start as the anti-vendor-lock-in answer to Cursor and Claude Code.

The core product is an AI coding agent that runs inside VS Code, JetBrains, or your terminal. You install it, point it at your codebase, and start telling it what to build. What makes Kilo different from Cursor is the model selection: it supports over 500 models, from Anthropic Claude to OpenAI GPT to Gemini to open-source alternatives, all routed at exact provider API rates with zero markup. If you’re already spending on API credits, Kilo doesn’t add a layer on top. That’s a real differentiator against tools that charge a flat subscription and then route you through their own model inference with a margin baked in.

The App Builder: Kilo’s play for non-coders

In early 2026, Kilo shipped an App Builder — a browser-based, natural language interface for spinning up full-stack web apps. The pitch is direct: describe what you want, watch it build in a live preview, deploy with one click. It runs on Next.js under the hood. You can take the generated code and continue developing it inside VS Code or hand it off to a developer.

The comparison to Lovable is intentional. CEO Scott Breitenother has been explicit about it: “Lovable is not a tool that engineers use. It’s for that cute proof-of-concept, or an idea, or that internal tool. Kilo is where you start building actual, real products.” Whether that’s accurate depends on what you’re building, but the App Builder does give you full code export and deploys to your own infrastructure — not a Lovable-controlled environment. For founders who’ve bumped into Lovable’s hosting constraints or wanted more control over the stack, that’s the relevant distinction.

Who uses this

The primary audience is software engineers who want a Cursor alternative with better model flexibility and no subscription commitment. The free tier is genuinely usable — you’re paying provider rates, not Kilo’s markup — so it suits developers who prefer to bring their own API keys and control costs directly.

For non-technical founders, the App Builder is the only real entry point. It’s more capable than it was at launch, but it still trails Lovable on polish and guided onboarding. If you’ve never used a vibe coding tool before, start with Lovable or Bolt. If you’ve hit their walls — code ownership, model constraints, pricing above a certain usage level — Kilo’s App Builder is the upgrade path worth trying.

Pricing

Kilo Code is free to install and use. You pay actual provider API costs through Kilo Credits (1 credit = $1 of API spend, no markup) or bring your own API keys entirely for free. Kilo Pass at $19/month bundles a credit allowance for teams that prefer predictable billing. There’s no premium model lock — every model available through Kilo is available on the free tier, limited only by your credit balance.

What works

Model freedom is the headline. Being able to swap between Claude Sonnet, GPT-5.5, or a locally-hosted Ollama model mid-project without changing tools is genuinely useful for workflows where different tasks suit different models. The codebase awareness (Kilo reads your entire project before acting) is solid, and the VS Code extension is actively maintained with frequent updates.

What doesn’t

The App Builder is early. It can build simple full-stack apps reliably, but complex multi-page apps with custom auth flows and third-party integrations still require handholding. Deployment is limited to a handful of supported hosts; if you’re not on Vercel or Netlify, expect friction. The 500-model pitch is technically true but practically overwhelming — most users will settle on two or three models and ignore the rest.

Documentation is improving but was sparse at launch. If you run into a problem, the GitHub issues page and Discord are your best resources.

Verdict

Kilo Code is the most honest tool in the coding agent category: open-source, no margin on API costs, full code ownership. For engineers, it’s a strong Cursor alternative. For non-technical founders, the App Builder is interesting but not yet polished enough to replace Lovable for a first project. Watch this space — the trajectory is right, and the pricing model is genuinely founder-friendly.
