Both are popular terminal coding agents. Here is how ANUS and OpenAI Codex stack up on price, strengths and weaknesses, and which one we would pick.

ANUS

Free terminal coding agent that auto-routes between free LLM tiers

6.5 /10

Pricing: Open source

Pros

Costs nothing to run end to end by cycling across multiple providers' free tiers (OpenRouter, Gemini, Groq, Cerebras, Mistral) as rate limits hit
Active project with MIT license, transparent local key storage, and a model-ranking list that refreshes twice a day

Cons

Quality and availability depend entirely on whichever free tier is currently up, so behavior can vary day to day; some providers' free tiers use submitted data

Our pick

OpenAI Codex edges it with a score of 9.1 versus 6.5. OpenAI Codex is the better fit if you value: included with chatgpt plans you may already pay for, open-source cli plus cloud tasks that open pull requests. Choose ANUS instead if you need: costs nothing to run end to end by cycling across multiple providers' free tiers (openrouter, gemini, groq, cerebras, mistral) as rate limits hit, active project with mit license, transparent local key storage, and a model-ranking list that refreshes twice a day.
