Choose ECC if…

  • ECC is primarily JavaScript; SAM is Swift.
  • License: ECC is MIT, SAM is GPL-3.0.
  • Pricing: ECC is free for open-source projects, but private repositories require a paid subscription starting at $19 per seat per month..
  • Requirements: ECC requires a JavaScript environment and can be installed via guided setup or native plugin commands..
  • Tags unique to ECC: ai-agents, anthropic, claude, claude-code.
  • Also covers Developer Tools.
  • Use ECC when you need to optimize the performance of AI agents and large language models, particularly if you are working with platforms like Claude Code, Codex, Opencode, or Cursor.

When NOT to use ECC

  • Avoid ECC if your project does not require the specific features it offers, such as skills, instincts, memory, security, and research-first development, and if you are looking for a more generalized L

Choose SAM if…

  • SAM is primarily Swift; ECC is JavaScript.
  • License: SAM is GPL-3.0, ECC is MIT.
  • Requirements: Min 4 GB RAM; For optimal use with local AI models, a system with 16GB+ RAM is recommended.; The system should be equipped with macOS 14.0 (Sonoma) or later..
  • Tags unique to SAM: ai-assistants, apple-silicon, open-source.
  • You should use SAM when you are working on a macOS system equipped with Apple Silicon as it is optimized for such hardware.

When NOT to use SAM

  • Avoid using SAM if you are developing on an Intel-based Mac or any system running a different operating system as it is specifically designed for macOS and Apple Silicon.
  • Do not opt for SAM if your project requires low memory consumption, because supporting local AI models typically demands high RAM (16GB+) and significant disk space.
