StackAI

What it is for

StackAI is an enterprise agent studio: drop nodes on a canvas, attach a knowledge base, then publish the same workflow as a chat, form, Slack bot, or API. Use it when the job is a governed internal agent IT will actually deploy, not when you need n8n-style node spaghetti you host yourself.

What makes it unique: the cover is StackAI’s own homepage product still — sidebar (Knowledge Base, Connections, Published Agents) plus a workflow graph on the canvas — not a pricing card.

Key features

• Workflow Builder — canvas of inputs, LLMs, knowledge, logic, and outputs you Run then Publish (Academy #1; First workflow). One canvas you author, not a generate.
• Knowledge bases — upload files or connect Drive / Notion / SharePoint so the agent cites a pile (pricing Knowledge Bases; Academy). A store, not a node type.
• Connections — databases and APIs the workflow can read and write (Academy “manage connections”). A pipe, not a prompt.
• Publish / export — share URL, Slack bot, Chrome extension, REST API, form UI from the same graph (pricing Plugins; Academy Export). Delivery, not a draft.
• Analytics + Manager — run counts, tokens, and a conversation inbox across the org (Academy Analytics / Manager). An ops desk, not a builder.

Agent Builder / Quick Start is a shorter path onto this canvas, not a second product. The AI copilot (“refine with AI”) sits on the same builder. Runs are the meter. Model names are SKU.

Who it's for

Best fit: ops and IT teams who will burn Free’s 500 runs on two projects and then talk to sales for Enterprise seats, SSO, and on-prem — there is no public mid-tier dollar card.

Pricing

Limitations / costs

• Free is 500 runs / 2 projects / 1 seat. There is no self-serve Team card.
• No public Enterprise dollar. Confirm the quote.
• A hosted studio, not a self-host graph. For nodes you run yourself, see n8n.

Alternatives

• n8n — self-host automation when StackAI’s enterprise canvas is not the job.
• Dify — another agent/app studio with a different canvas.
• MindStudio — no-code agents when you want a $16–$20 individual card, not an Enterprise quote.
