|---|---|---|
| What it costs | ||
| Pricing | Open source | Freemium |
| Pricing details | The CLI and SDK are Apache-2.0 and free to install from npm as @openai/codex-security. Scans are billed as model usage against your own key, and OPENAI_API_KEY, Amazon Bedrock, OpenRouter and Fireworks all work as providers. Set a soft ceiling with --max-cost; the docs are explicit that it is an estimate, not a hard spending cap. Note that some cybersecurity requests and protected findings require approval through Trusted Access for Cyber. | Free tier gives 15 tasks a day and 3 concurrent tasks. Jules Pro raises that to 100 tasks a day and 15 concurrent with Gemini 3 Pro, and Jules Ultra to 300 tasks a day and 60 concurrent with priority access to new models. Paid tiers are sold through Google AI subscriptions rather than priced on the Jules page. |

An Apache-2.0 CLI and TypeScript SDK that finds vulnerabilities, validates them before reporting, and proposes fixes. | Google Labs coding agent that clones your repo to a cloud VM, plans with Gemini, writes the change and opens a pull request for review. Free tier included. |
