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
