Power Apps vs Power Automate vs Power Pages vs Dataverse vs Copilot Studio
Verdict: Match the service to the outcome: build an app on Power Apps, automate a workflow on Power Automate, publish an external site on Power Pages, store the data in Dataverse, answer in natural language with Copilot Studio.
| Criterion | Power Apps | Power Automate | Power Pages | Dataverse | Copilot Studio |
|---|---|---|---|---|---|
| Delivers | Cross-platform business apps, minimal code | Automated workflows between apps and services | External-facing business websites | Secure table store for business data | AI-driven conversational agents |
| Audience | Internal staff on phone, tablet, web | No UI; runs in the background | External public, customers, partners | None directly; the shared data layer | End users asking questions |
| Choose when | Staff capture or view data through a tailored screen | Repetitive re-keying, notifications or sync between systems | Non-staff submit or track records through a public site | One secure store several components build on with role-based access | Deflect repetitive enquiries with natural-language replies |
| Data relationship | Reads and writes many sources through connectors | Acts on connected data, does not store it | Reuses the same shared Dataverse data | Is the store; integrates multiple sources into one | Consumes data through connectors |
Rules
- Choose Power Apps to build cloud-connected cross-platform business apps with minimal code that read and write business data.
- Choose Power Automate to optimise a business process by creating automated workflows between apps and services, removing manual re-keying.
- Choose Power Pages to create and host secure external-facing business websites that run across browsers and devices and reuse Dataverse data.
- Choose Dataverse when several components need one secure store: it holds business data in tables with role-based access and integrates multiple sources.
- Choose Copilot Studio, the graphical low-code tool, to build AI-driven conversational agents rather than writing custom code.
- Power Fx is the low-code declarative formula language used across the platform, not a service that builds apps, flows or sites.
Traps
- Power Apps builds internal apps; a public site for non-staff residents or partners is Power Pages, not Power Apps.
- Dataverse stores the data but does not automate the workflow or build the user interface.
- Power Automate builds workflows, not the external website that residents browse to submit requests.
- The formula-language description belongs to Power Fx and is offered as a decoy for Dataverse, Power Automate or Copilot Studio.
