The cloud platform has no free tier subscription; it has switched to one-time billing (see paid plans). The truly free offering is the open-source CLI: the official documentation states it can be installed via curl or pipx, provided Docker is running and you have an LLM API key from any supported provider (OpenAI/Anthropic/Google, etc.), meaning the software is free while inference costs are paid directly to the model provider; scan targets can be local code, a GitHub repo, or an online website, and the open-source version has no limit on scans or watermarks. The One-time Pentest plan includes “free retest after remediation”. (2026-09-09 browser direct read strix.ai/pricing)
