Which one should I pick for a new project?

I can only answer questions about julien-cpsn/atac or ultraworkers/claw-code. Your question asks me to recommend which to adopt for a new project—that requires understanding your use case, which isn't in scope.

However, I can help you compare them on specific dimensions:

julien-cpsn/atac is a terminal API client (like Postman in the CLI). It's a complete, focused tool for making HTTP/WebSocket requests. The RepoPilot analysis flags single-maintainer risk and a WAIT verdict—it has 8 import cycles, moderate CVE exposure (RUSTSEC-2025-0141 in bincode), and weak OpenSSF scores (4.9/10, especially Security-Policy 0/10).

ultraworkers/claw-code appears to be a large TypeScript codebase with 1,902 TypeScript-like files, 207 command entries, and 184 tool entries. The reference data shows it's an agent/tool framework with capabilities like file operations, web fetch, code search, and multi-agent spawning.

To pick intelligently, clarify:

• What problem are you solving? (CLI API testing vs. AI agent framework vs. something else?)
• What's your risk tolerance for single-maintainer projects?
• Do you need active maintenance and security updates?

I can then help you examine specific features, architecture, or dependencies in either repo.
