Stacks Ai

StackAI (Stack AI, Inc.) is an enterprise AI agent platform that lets teams build, deploy, and govern no-code agentic workflows at scale. Its visual Workflow Builder chains LLMs, knowledge bases, connections, and logic nodes into production agents that can be deployed as a REST API, chat assistant, form, or batch job. The public StackAI API runs deployed flows, manages Knowledge Bases and their file resources (upload, index, sync, cursor-paginated listing), and reads flow-run analytics. The platform targets regulated industries with SOC 2 Type II and ISO 27001 certifications, RBAC/SCIM governance, and multi-tenant, VPC, and on-premise deployment options. Backed by Lightspeed Venture Partners.

Stacks Ai publishes 5 APIs on the APIs.io network, including analytics API, Knowledge Base Resources API, Knowledge Base Sync API, and 2 more. Tagged areas include Company, Artificial Intelligence, Agents, LLM, and No-Code.

Stacks Ai’s developer surface includes documentation, API reference, getting-started guide, pricing, signup flow, engineering blog, and 15 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/stacks-ai: open an issue to ask a question, or submit a pull request to add artifacts.
