AgentWorks vs StackAI

EU AI Act readiness, multi-LLM choice, and transparent € pricing — compared on the points that actually move a buying decision.

Last verified: July 10, 2026

TL;DR

StackAI is a US (San Francisco, Y Combinator) no-code, drag-and-drop platform for building enterprise AI agents — strong at document-heavy back-office automation, with SOC 2 Type II, HIPAA, and forward-deployed engineering support. It publishes only a Free tier and a contact-sales Enterprise tier, priced in USD with data residency unspecified. AgentWorks is the EU-native alternative: EU data residency, per-agent EU AI Act risk classification, gateway PII masking, transparent per-token € pricing, and a self-serve paid path.

When StackAI is the better choice

StackAI is the stronger pick for US enterprises building document-heavy agents with hands-on deployment support.

  • You are a US-based enterprise and do not need EU data residency or EU AI Act tooling.
  • Your core use case is document-heavy back-office automation with many data loaders.
  • You need SOC 2 Type II and HIPAA on the vendor questionnaire today.
  • You want a mature drag-and-drop visual builder and forward-deployed engineering support.
  • You are comfortable with a contact-sales Enterprise motion and USD contracting.

When AgentWorks is the better choice

AgentWorks is the right pick for European teams that need EU residency, AI Act tooling, and transparent € pricing without a sales call.

  • You need EU data residency or self-hosted deployment on Azure, AWS, GCP, or IBM — not a US platform with unspecified hosting.
  • You must comply with the EU AI Act and want per-agent risk classification, audit log, and HITL built in.
  • You want PII redacted at the gateway before any model sees data.
  • You want a self-serve paid path (Pro €39/month, Team €49/seat/month) instead of jumping straight to contact-sales.
  • You want transparent per-token € pricing on a live wallet — not a custom USD Enterprise quote.
  • You want multi-LLM choice (GPT-5, Claude, Gemini, Mistral) with an AUTO router in one workspace.

Migrating from StackAI to AgentWorks

A practical six-step path. Run both systems in parallel for one week before cutting over.

  1. 1Inventory your StackAI projects: which are document-processing pipelines and which are general-purpose agents.
  2. 2Map each StackAI agent to the closest AgentWorks template (50+ pre-built); flag the rest for AgentWorks AI-engineer custom builds.
  3. 3Re-create data-loader sources as AgentWorks knowledge bases (documents and URLs) hosted in the EU.
  4. 4Rebuild StackAI node flows as AgentWorks multi-agent pipelines; re-implement triggers as scheduled runs or webhooks.
  5. 5Apply per-agent EU AI Act risk classification and turn on human-in-the-loop on customer-impacting steps.
  6. 6Run both systems in parallel for one to two weeks, comparing outputs, audit logs, and cost (USD enterprise contract vs € wallet) before redirecting traffic.

FAQ

AgentWorks vs StackAI — common questions

Is AgentWorks a StackAI alternative for European businesses?
Yes. StackAI is a US (San Francisco) platform whose pricing page does not document EU data residency and which does not advertise EU AI Act tooling. AgentWorks is EU-native: EU regions or self-hosting, per-agent EU AI Act risk classification, gateway PII masking, and transparent per-token € pricing.
How does AgentWorks pricing compare to StackAI?
StackAI publishes a Free tier (500 runs/month, 2 projects, 1 seat) and a contact-sales Enterprise tier priced in USD, with no public per-run or per-token price. AgentWorks has a permanent Free tier plus self-serve Pro (€39/month) and Team (€49/seat/month), with tokens billed transparently at cost + 10% from a live € wallet and 2 months free on yearly billing.
Where is StackAI data hosted, and where is AgentWorks data hosted?
StackAI is US-headquartered and its pricing page does not specify hosting regions or EU data residency, so EU teams should confirm this in the DPA. AgentWorks hosts in EU regions by default and offers self-hosted deployment on Microsoft Azure, AWS, Google Cloud, or IBM Cloud, including EU-only configurations.
Is StackAI EU AI Act compliant?
StackAI advertises SOC 2 Type II, HIPAA, and GDPR compliance for Enterprise customers but does not position the platform around EU AI Act deployer obligations (per-agent risk classification, audit logging, human-in-the-loop). AgentWorks ships those as core platform features.
Does AgentWorks have a no-code builder like StackAI?
AgentWorks is chat-first with 50+ pre-built templates and visual multi-agent pipelines, so business users can deploy agents without code. StackAI leans on a drag-and-drop visual node builder, which is a genuine strength for engineers assembling document-processing flows. Match the tool to who owns the agents.
Can I migrate my StackAI projects to AgentWorks?
Yes. Inventory your StackAI projects, map each agent to an AgentWorks template (50+ pre-built), re-create data loaders as EU-hosted knowledge bases, rebuild node flows as multi-agent pipelines, apply EU AI Act risk classification with HITL, and run both in parallel for a week or two before switching over.
