Last verified 2026-11-01. Live pricing page (stackai.com/pricing) fetched and shows only Free ($0) and Enterprise (custom). The mid-2025 Starter ($199) and Team ($899) tiers referenced by third-party sources are absent from the live page and unconfirmed, so they are excluded. SOC2 Type II + HIPAA + GDPR + ISO 27001 confirmed on the homepage and blog (stackai.com/blog/soc2-type2-hipaa).

This standing as a plaque
Stack AI currently holds a bronze deskmark here — Rank 5 of 8 · AI Agent Platforms. Anyone may show it. There is nothing to apply for, nothing to pay, and displaying it changes no score: the standing comes from the published algorithm, which never reads commission data. We never ask anyone to show it, and its link carries rel="nofollow".
The image is drawn from our live data, so it follows the standing rather than freezing it: if Stack AI moves up or down a tier, the plaque on your own site says so at our next publish. Nothing is tracked beyond the ordinary web-server log that records any image request.
