Bubble.io vs Microsoft Power Apps: Which Should a Professional Firm Choose?
Platform Comparison · Bubble vs Power Apps
A fair comparison of Bubble.io and Microsoft Power Apps by ecosystem, identity, external users, licensing and fit.
Last updated: October 2026. Written by Athar Ahmad, Certified Bubble.io Developer and Tech Architect, Simple Automation Solutions.
Quick answer
Microsoft Power Apps is a low-code platform for business apps tightly integrated with Microsoft 365, Dynamics and Azure, with Microsoft identity and governance, and Power Pages for external portals. Bubble.io is a standalone application platform suited to branded, external-facing portals and products with simpler licensing for external users. Choose Power Apps when your organisation is standardised on Microsoft and wants internal apps within it, and Bubble.io for distinctive client-facing experiences. We build on Bubble.io, so this includes a disclosure; check current features and licensing for both.
Key takeaways
- Power Apps: best inside the Microsoft ecosystem for internal apps; Bubble: standalone, branded external portals.
- External-user licensing can be complex in Microsoft’s model; compare carefully.
- Microsoft expertise helps with Power Apps administration.
- Some firms use Power Apps internally and another platform for clients.
- Disclosure: we build on Bubble.io; verify current features and licensing.

Limits to be aware of
Microsoft Power Apps
- Licensing can become complex, especially for external users.
- It assumes Microsoft expertise.
- Fully custom branding for external users takes more effort.
Bubble.io
- Less native integration with Microsoft’s ecosystem.
- You manage identity and governance within the app’s own rules.
- Usage-based costs depend on design. See workload units.
Can you use them together?
Some firms use Power Apps for internal tools inside Microsoft 365 and a separate platform for the external, client-facing experience, connecting them where needed. That keeps internal governance in Microsoft’s hands without forcing external clients into a Microsoft licence model. See our security guide and what to cut before you build.
How to decide in five questions
- How complex are your roles, rules and data? More complexity favours a fuller platform.
- Is the product web, mobile or both?
- How sensitive is the data? Check how access control works and how it is tested. See our security guide.
- Who will maintain it? Choose something you or a partner can support.
- What will it cost over three years, including platform fees and support?
