The honest brief

Manus

A general operator that plans and executes multi-step non-code work autonomously, not a single-prompt chatbot.

  • Runs tasks autonomously over hours
  • Multi-agent orchestration in a Linux sandbox
  • Strong GAIA benchmark scores
  • Browses, drafts, and schedules for you
  • Credits drain fast on complex tasks
  • Reliability gaps; tasks fail mid-stream
  • No SOC 2 / ISO 27001 / HIPAA as of 2026
  • China data-flow compliance concerns

OpenAI Codex CLI

Open-source Rust rewrite of OpenAI's terminal coding agent; sign in with a paid ChatGPT plan or bring your own API key.

  • Runs locally in your terminal
  • Fast Rust implementation
  • MCP tools and parallel subagents
  • Reviewable conversational edit loop
  • Best with OpenAI/GPT models
  • Terminal-only, no full IDE
  • Newer than rival CLIs
