Your AI Coding Assistant Shouldn’t Be a Black Box
You’re paying $20/month for Cursor, and you have no idea what’s happening under the hood. Which model is it actually using? Is it compressing your context? Is it silently dropping important files from your prompt?
These aren’t hypothetical complaints — they’re the exact frustrations driving over 1.4 million developers to Kilo Code.
Kilo Code is an open-source (Apache-2.0) AI coding agent that gives you full visibility into every request, lets you choose from 500+ models, and charges you the exact API price with zero markup. No subscriptions. No hidden fees. No mysterious “slow pool” degradation.

What is Kilo Code?
Kilo Code started as a fork of Cline (itself a popular VS Code extension for AI-assisted coding) but has rapidly evolved into a full agentic engineering platform. Built by the team behind one of VS Code’s most-downloaded extensions, it now supports VS Code, JetBrains IDEs, and a standalone CLI.
Unlike subscription-based competitors like Cursor or GitHub Copilot, Kilo uses a pay-as-you-go model where you pay the exact API price from providers like Anthropic, OpenAI, and Google. There’s no monthly fee — you only pay for what you use.
The platform is fully open-source under Apache-2.0, meaning you can inspect every prompt, see exactly what context is being sent, and verify there’s no silent compression or model switching happening behind the scenes.
Key Features
Multi-IDE & CLI Support: Code Anywhere, Continue Everywhere
Kilo Code doesn’t force you into a single editor. Start a task on your phone, continue in VS Code, finish in the terminal — your session state, agent context, and variables persist automatically across all interfaces.
This is a genuine differentiator. Cursor locks you into their modified VS Code fork. GitHub Copilot works across editors but lacks the agentic capabilities. Kilo gives you both.
500+ Models, Zero Markup
Choose from over 500 models across 60+ providers. Use Claude 4 Sonnet for complex architecture, GPT-5 for quick fixes, Llama for budget-friendly work, or local models via Ollama and LM Studio.
The pricing model is refreshingly honest: you pay exactly what Anthropic/OpenAI/Google charges. Kilo makes money on Teams and Enterprise plans, not by marking up API calls. They even offer a “Kilo Pass” with up to 50% bonus credits on AI subscriptions.
Orchestrator Mode: Be Everywhere at Once
Orchestrator Mode lets you plan, build, and audit simultaneously with multiple agents working in parallel. Think of it as having a senior engineer, a code reviewer, and a planner all working on your codebase at once.
Combined with built-in AI code review, you can go from “commit” to “live” without leaving your IDE.
Memory Bank: Your Codebase’s Living Documentation
The Memory Bank stores architectural decisions, coding patterns, and project context. New team members (human or AI) can onboard automatically by reading from the Memory Bank instead of asking the same questions repeatedly.
This is particularly valuable for teams — capture what your best developers know and make it accessible to everyone.
Full Transparency: See Everything
Every request shows you exactly what model is being used, the full prompt being sent, the context window size, and what’s included. No auto-model switching, no silent context compression, no cut-offs you can’t see.
For developers who’ve been burned by opaque AI tools, this level of visibility is non-negotiable.
Pricing

After extensive testing across multiple programming languages and project types, Kilo Code demonstrates several advanced capabilities that set it apart from basic AI coding assistants:
Context-Aware Code Generation
Kilo Code excels at understanding project context beyond individual files. During testing with a React application, it automatically recognized the component structure, state management patterns, and styling approach without explicit instruction. When I requested a new component, it generated code that perfectly matched the existing architectural patterns and naming conventions.
The system maintains context across coding sessions, remembering previous decisions and coding patterns. This persistence proved particularly valuable when working on multi-day projects where consistency is crucial.
Intelligent Code Refactoring
One of Kilo Code’s standout features is its sophisticated refactoring capabilities. I tested it with legacy JavaScript code that needed modernization, and it automatically identified opportunities for ES6+ improvements, performance optimizations, and better error handling—all while maintaining functional equivalence.
The refactoring suggestions aren’t just superficial changes. Kilo Code understands code smells, design patterns, and best practices, offering meaningful improvements that enhance maintainability and performance.
Multi-Language Project Support
Testing revealed impressive capabilities across different programming languages within the same project. For a full-stack application using Python (Flask), JavaScript (React), and SQL, Kilo Code seamlessly transitioned between languages while maintaining consistency in naming conventions, error handling patterns, and architectural decisions.
The system understands the relationships between different parts of a tech stack, generating complementary code across frontend, backend, and database layers that work together cohesively.
Advanced Debugging and Error Analysis
Kilo Code’s debugging assistance goes beyond simple error identification. When presented with complex runtime errors, it analyzes the full stack trace, identifies potential root causes, and suggests specific fixes. During testing with a memory leak in a Node.js application, it not only identified the problematic code but also explained why the leak occurred and provided a detailed solution.
The system also performs static analysis, identifying potential issues before they become runtime problems. This proactive approach significantly reduces debugging time and improves code quality.
