NinjaCode vs OpenAI Codex
Codex is OpenAI’s coding agent, tied to OpenAI models and ChatGPT plans. NinjaCode runs the same agentic workflows with any frontier model — including OpenAI’s — under one credit plan.
| Feature | NinjaCode | OpenAI Codex |
|---|---|---|
| Editor | VS Code, JetBrains, Zed, Neovim + CLI | Terminal + IDE plugin |
| Source code | Open — GPL-2.0 agent core | CLI open, service closed |
| Models | Anthropic, OpenAI, DeepSeek, Mistral, Scaleway, xAI, Kimi, GLM | OpenAI only |
| Pricing | Credit plans from €20/mo, degressive tiers | ChatGPT plan bundles |
| BYOK | Yes, free | API key mode only |
| Permissions & checkpoints | Granular, shadow-git restore | Sandbox approvals |
| Usage transparency | Per-request tokens and credits | Plan limits |
If you want one vendor’s models, Codex is fine. If you want the best model for each task without switching tools — and a usage meter you can read — that’s what NinjaCode was built for.
