How much does Stack AI cost in 2026?
Quick Answer: Stack AI now publishes only two tiers (verified July 2026): Free ($0, 500 workflow runs/month, 2 projects, 1 seat, Discord support) and Enterprise (custom — SSO, audit log, SOC 2 Type II, private model deployment, dedicated support). The self-serve Builder ($99/month) and Team ($499/month) tiers that appeared in earlier data are no longer on the official page (they now show up only on third-party sites). LLM token costs are passed through at provider rates, with bring-your-own-key available. Stack AI is an enterprise AI-agent builder positioned for compliance-heavy deployments.
Stack AI Pricing (as of July 2026)
Stack AI's official page now shows only two tiers — a self-serve Free tier and a custom Enterprise.
| Plan | Price | Key Limits |
|---|---|---|
| Free | $0 | 500 workflow runs/month, 2 projects, 1 seat, Discord support, all LLM providers |
| Enterprise | Custom | SSO, audit log, SOC 2 Type II, private model deployment (Claude on Bedrock, OpenAI on Azure), dedicated CSM, custom SLAs |
The Builder ($99/month) and Team ($499/month) tiers implied by earlier data are no longer on the official pricing page — those figures now appear only on third-party sites, so treat them as unofficial. LLM token costs are passed through at provider rates (no markup), and bring-your-own-key (BYOK) is supported.
How Stack AI compares (enterprise AI agents)
| Platform | Model | Compliance |
|---|---|---|
| Stack AI | Free + Enterprise quote | SOC 2 Type II, private model deployment |
| Relevance AI | Free + Enterprise (Actions/credits) | SSO, dedicated infra |
| Dust | Pro $30/seat + Enterprise | SSO, SCIM |
| Lindy | Plus $49.99 → Enterprise | Standard |
Stack AI positions for enterprise use cases with a strong compliance and private-deployment story; the removal of public self-serve tiers pushes teams either onto the Free tier for evaluation or into an Enterprise conversation.
Editor's Note: Stack AI's differentiator is its enterprise deployment and compliance story — private model deployment on Bedrock/Azure and SOC 2 — which is why it competes with Relevance AI at the top of the AI-agent-builder market. Re-checked July 2026: the official page now lists only Free (500 runs/month) and Enterprise (custom); the Builder $99 and Team $499 tiers are gone from the official page (only third-party sites still cite them) — so evaluate on the free tier and expect an Enterprise quote for production, budgeting LLM token pass-through on top. — Rafal Fila, ShadowGen
