What is Stack AI?

Stack AI is an enterprise AI agent factory with a visual workflow builder, RAG knowledge bases, 100–500+ integrations, and deployment options from multi-tenant cloud to VPC and on-prem. It helps GTM and ops teams turn document-heavy processes—Q&A over playbooks, CRM updates, research memos, and customer-facing chatbots—into governed agents without assembling retrieval, integrations, and compliance controls separately.

Key features

Visual Workflow Builder

Drag-and-drop canvas connecting LLMs, knowledge bases, logic, code (Python/JS), and app nodes with an in-builder assistant.

RAG Knowledge Bases

One-click ingestion from files, web scraping, Google Drive, Notion, and business systems with PDF/Office readers.

Multi-Model & BYOK

OpenAI, Anthropic, Google, Meta, Mistral, Azure, Bedrock, local endpoints, and admin governance over allowed providers.

Agents & Tool Calling

LLM nodes invoke tools, route requests, and execute actions across Salesforce, SharePoint, Slack, HubSpot, and more.

MCP Connectivity

Connect third-party Model Context Protocol servers alongside native StackAI integrations.

Publishing Surfaces

Deploy as hosted UIs, REST APIs, custom domains, Slack/Teams bots, and Chrome extensions.

Human-in-the-Loop

Approval steps and admin review on sensitive workflows before outputs or system writes ship.

Enterprise Security

SOC 2 Type II, HIPAA and GDPR support claims, PII redaction, RBAC, SSO (Okta/Entra), audit logs, VPC/on-prem.

Stack AI pricing

Public self-serve Free tier: $0/month with 500 runs, 2 projects, and 1 seat (community Discord support). Production deployments are Enterprise custom quotes—third-party guides cite five- to six-figure annual minimums and AWS Marketplace listings at $120K/year for 5,000 runs/month hosted. Model/API usage may be additional depending on deployment terms.

Pros & cons

Pros

  • + Visual builder lets non-engineers prototype GTM agents while IT keeps governance.
  • + Strong compliance posture for regulated industries (finance, healthcare, defense logos).
  • + LLM-agnostic design avoids vendor lock-in on a single model provider.
  • + RAG and integrations in one product accelerates internal copilots and customer bots.
  • + Flexible deployment (cloud, VPC, on-prem) fits strict data residency requirements.
  • + Mature observability and audit logging for production agent oversight.

Cons

  • − No published mid-tier plan; 500 free runs/month is sandbox-only for real GTM volume.
  • − Enterprise pricing is opaque and typically requires long procurement cycles.
  • − Integration counts vary across marketing pages (70–500+), so due diligence is needed.
  • − Complex workflows still demand technical owners for maintenance and testing.
  • − AWS and analyst estimates suggest high entry cost versus lighter no-code agents.
  • − Feature-rich UI can overwhelm teams seeking simple chat-first automation.

Who is Stack AI best for?

  • • Enterprise GTM and enablement teams building governed internal copilots over Salesforce and SharePoint.
  • • Regulated organizations needing VPC/on-prem and HIPAA/SOC 2 alignment.
  • • RevOps and solutions engineers codifying repeatable research, Q&A, and document workflows.
  • • Teams with budget for white-glove implementation and dedicated solution engineers.
  • • Companies standardizing on one agent platform across departments rather than many point tools.

Frequently asked questions

Is Stack AI really free?

Yes for evaluation: the Free plan allows 500 workflow runs per month with one seat. Production-scale usage requires an Enterprise quote with custom run and seat limits.

Can Stack AI deploy on-premises?

Yes. Enterprise offers customer VPC and on-prem deployment with the same builder, targeting data sovereignty and regulated workloads.

What counts as a run?

A run is one execution of a workflow or published agent interface. Heavy automation quickly exceeds the 500-run free cap.
