Compare / Manus AI vs OpenAI Codex
Head-to-head
Manus AI vs OpenAI Codex.
Side-by-side on ratings, pricing, pros, cons, and the honest take on which to pick. Cross-category comparison: Manus AI is a autonomous agent and OpenAI Codex is a coding agent.
| Manus AI | OpenAI Codex | |
|---|---|---|
| Rating | 3.5 / 5 | 3.5 / 5 |
| Category | Autonomous Agent | Coding Agent |
| Tech level | no code | developer |
| Open source | No | Yes (Apache 2.0) |
| Pricing | Free tier with limited daily usage. Paid plans start at ~$39/month. Enterprise pricing on request. Pricing has shifted multiple times in 2025–2026. | Pro $20/month base + usage-based credits ($20/mo of frontier model included). Pro+ $60/month (3× usage). Ultra $200/month (20× usage). No free tier. Rolling 5-hour credit limits frustrate heavy users. |
| Best for | Non-technical builders who want an autonomous agent that can browse the web, research, and produce structured deliverables — without setting up a CLI or writing prompts repeatedly. | Developers committed to GPT-5+ models who want a Claude Code equivalent without leaving the OpenAI ecosystem. Teams that prioritise the most recent OpenAI features. |
| Not for | Developers who already have Claude Code, OpenAI Codex, or a similar agentic setup. The autonomous-browser angle is less useful when you already have a code-aware agent that can browse via MCP. | Anyone who needs predictable monthly costs (rolling credit limits cause unpredictable workflow blocks) or who wants to use Claude or Gemini in their workflow. |
Our verdict on Manus AI
Went viral in 2025 for autonomous browser demos. Genuinely capable for research tasks; less differentiated for builders who already have a coding agent setup.
Full Manus AI review →Our verdict on OpenAI Codex
3M weekly active users and 70%+ MoM token growth. Rolling 5-hour credit limits are a real operational pain. Best if you're in the OpenAI ecosystem.

What works
- Genuinely autonomous — can complete multi-step tasks without per-step prompting
- Browser-native — handles workflows that require navigating real websites
- No-code interface, accessible to non-developers
- Free tier available for evaluation
- Strong viral mindshare — clients sometimes recognise the brand
What doesn't
- Pricing has shifted multiple times — verify current rates before committing
- Quality varies significantly by task type
- Less useful for builders who already have a code-aware agentic setup
- Closed-source, China-based provider — data residency may matter for some
- Slower than direct API approaches for tasks that don't need browser access
OpenAI Codex
What works
- Fastest-growing tool in the category — 3M weekly active users
- Multi-agent v2 workflows with inter-agent messaging
- Integrated terminal reader — sees stdout/stderr from your dev server
- Rust-based for speed and efficiency
- Strong cross-platform: Windows native, macOS, Linux, WSL2
- Open source CLI — Apache 2.0 licensed
What doesn't
- Rolling 5-hour credit limits cause unpredictable workflow blocks
- OpenAI model lock-in — can't use Claude or Gemini
- No model selection — system chooses automatically
- Pricing increased ~20% in 2026 even though models got more efficient
- MCP server support unclear — limited extensibility vs Claude Code
Which to pick
These two are closely matched. Don't pick on overall rating — pick on use case. Manus AI for non-technical builders who want an autonomous agent that can browse the web, research, and produce structured deliverables — without setting up a cli or writing prompts repeatedly. OpenAI Codex for developers committed to gpt-5+ models who want a claude code equivalent without leaving the openai ecosystem. teams that prioritise the most recent openai features.
Honest middle: most serious operators end up using more than one tool. If you're early in your AI agent journey, our five-question picker recommends a starting platform from your specific situation.
