FEATURES

• Build with an AI Coding Agent: BuilderStudio gives you an AI-powered coding workspace designed to help you move from idea to working product faster. Instead of starting from a blank editor, you can

describe what you want to build, refine the result, and keep improving your app with an agent that understands your project.

• Choose from 300+ AI Models: Every project is different, and every task needs the right model. BuilderStudio gives you access to a wide range of AI models through OpenRouter, so you can choose the best option for speed, quality, reasoning, or cost.

• Connect Your Workflow with MCP: BuilderStudio includes built-in support for MCP, making it easier to connect your AI coding agent with the tools, services, and context your project depends on.

• Extend BuilderStudio with Skills: BuilderStudio is built to grow with your workflow. With skills, you can add focused capabilities to your AI coding environment, from accessibility checks and documentation support to release workflows, code quality improvements, and project-specific automation.

• Powerful Agentic Development, Made Affordable: AI coding tools should help you build more without making every experiment feel expensive. BuilderStudio is designed to make agentic development more accessible, practical, and affordable for solo builders, startups, and teams.
