The general user free tier includes 2,000 completions and 50 chats per month. Open-source maintainers and teachers can upgrade to Pro for free. The free student plan has reopened for new applications since 2026-06-17, after being suspended since 2026-04-20 for 58 days. As of 2026-07-27, the model selection for Free and Student plans has been limited to only Auto, and manual model specification is no longer available, while Pro and above plans are not affected.
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)
