- Supports native subagents and MCP for complex multi-agent workflows
- Includes features like checkpointing, cron jobs, and web fetch
- Built in TypeScript, ensuring type safety and modern development experience
- Ideal for creating bespoke coding agents and CLI tools
Cons
- Requires familiarity with TypeScript and open-source development
- Limited out-of-the-box features; customization demands technical expertise
- No active user base or community support indicated currently
Best for
- • Developing custom AI coding agents for automation
- • Creating specialized CLI tools with complex workflows

Figma for Claude Code
Inspector reimagines the design-to-code workflow by integrating visual editing directly with AI-powered code generation. Designed for developers, designers, and product teams, it allows users to click on UI elements within a design interface, make visual adjustments, and have those changes automatically reflected in the underlying codebase. The tool connects seamlessly with popular AI agents like Claude Code, Codex, and Cursor, streamlining the often tedious handoff process between design and development. Its unique approach eliminates the need for manual code edits or back-and-forth communication, enabling rapid prototyping and iteration. By bridging the gap between visual design and code, Inspector enhances productivity and fosters a more collaborative workflow, making it ideal for teams seeking to accelerate their development cycles with AI-powered precision.
Pros
