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)
Light daily and weekly quotas, only some models available, with unlimited Tab autocomplete and inline editing (changed from a credit system to a quota system on 2026/3/19). Re-check on 2026-08-11 found that windsurf.com/pricing now permanently redirects to devin.ai/pricing, that the page is entirely Devin-branded and that the standalone Windsurf pricing page no longer exists (the brand has been folded into Devin). The plan figures here are still consistent with the new page and have not changed.
