The Stack / Automation
StackAI
04 AutomationA harder yes than it used to be — Stack AI dropped its self-serve Starter/Pro tiers in 2026 and now sells only a capped Free plan or custom Enterprise (five-to-six-figure annual minimum, 60–90 day procurement). It's still the right call for governed internal AI apps at real enterprise scale; teams that outgrow the free cap without enterprise budget now have no bridge tier and should look elsewhere.
The job in the stack
The internal-AI-apps seat: drag-and-drop LLM workflows — document processing, internal assistants, approval chains — deployed to your team.
Pricing
| Plan | Price | Notes |
|---|---|---|
| Free | $0 | 500 workflow runs/mo, 2 projects, 1 seat, Discord community support |
| Enterprise | custom | Unlimited runs/projects/seats, SSO, SOC 2/HIPAA/GDPR, on-prem/VPC, dedicated engineers — 5-to-6-figure annual minimum typical |
Pricing verified 2026-08-26. Plans change — the source of truth is StackAI's own pricing page.
Models & versions
- Workflow builderMulti-model LLM chains, RAG, forms, and app interfaces
The honest read
What works
- +Internal AI apps with real interfaces, not just chat windows
- +Enterprise posture: access control, data governance, on-prem options
- +Multi-model: route steps to whichever LLM fits
What breaks
- −No self-serve mid-tier anymore — it's Free (500 runs/mo) or Enterprise procurement, nothing between
- −Overlaps n8n for workflow automation; justify the second seat
- −Complex apps still need someone who thinks in data flows
Use it for
- →Enterprises with the budget and compliance need to justify custom pricing
- →Document-heavy operations: intake, extraction, approval flows
- →Teams that need AI apps non-technical staff can actually use
Skip it if
- ×You're solo or mid-size without enterprise budget — there's no bridge tier now; n8n plus Claude covers this cheaper
- ×You just need one chatbot on your site — that's CustomGPT's job
Questions operators ask
?Stack AI or n8n?
n8n if you're automating workflows and comfortable with a builder's learning curve. Stack AI if you're shipping governed internal AI apps to a team that needs interfaces, permissions, and compliance — and has the enterprise budget the pricing now requires.
What changed
- Freshness sweep: no changes. Still Free (500 runs/2 projects/1 seat) or custom Enterprise — no self-serve bridge tier has reappeared.
- Rebrand and domain move: "Stack AI" on stack-ai.com is now "StackAI" on stackai.com (301, affiliate parameter survives — we repointed both links anyway). Pricing unchanged and re-verified: Free at 500 runs/2 projects/1 seat, Enterprise custom, still nothing self-serve in between. Our URL slug stays /tools/stack-ai.
- Freshness sweep: real strategic shift found. Stack AI discontinued its self-serve Starter (~$199/mo) tier entirely — the official pricing page now shows only Free (500 runs/mo) and custom Enterprise (5-to-6-figure annual minimum, 60-90 day procurement). Rewrote verdict, cons, best_for, and skip_if to reflect the missing bridge tier.
- Added to the stack (internal-AI-apps seat). Pricing seeded from January 2026 baseline, pending fresh verification by the update loop.
