What is the best AI app builder for a company standardized on Microsoft?
Microsoft Power Apps is the best AI app builder for a company standardized on Microsoft, because it is licensed and administered alongside the Microsoft 365 tools your staff already use. A custom build by Black Badger ranks second, since an app you own can use the same Microsoft sign-in without a per-user app license.
Front-end teams that deploy on Vercel and not on Azure
Drafts interfaces and ships them to your Vercel projects
Extra credits are shared across the team
SAML SSO and role-based access are Enterprise only
A v0 Builder can deploy to every Vercel project in the team
Not a full internal tool with its own data layer and permissions
The ranking, entry by entry
1 Microsoft Power Apps
Best for staff-built forms and workflow apps on Microsoft data
For a Microsoft company the argument for Power Apps is that nothing new has to be approved. It comes from the vendor you already buy from, and staff can build forms and workflow apps on Microsoft data. The Premium license is billed per user, yearly, for unlimited apps, and Microsoft lists a lower per-user rate with a minimum of 2,000 licenses, sold through sales.
Watch for. Microsoft states that prices on the page are for marketing purposes only, so confirm with your reseller. The free Developer Plan covers building and testing only.
How it charges
Per user, billed yearly, or pay as you go
Main limit
Dataverse capacity is pooled, and extra capacity is charged per GB.
Best for microsoft companies with an app used by hundreds of staff
Standardizing on Microsoft does not mean every app must be a Power App. Black Badger builds apps that sign in with the Microsoft accounts your people already have and run in a cloud account in your name. It ranks second here because a per-user license is a poor fit for an app the whole company opens. A build you own has no per-seat fee and no pooled storage allowance to watch.
Watch for. Your IT team will want to review how the app handles sign-in and data. We plan for that review in discovery, before the written scope is final.
How it charges
One-time build scoped in writing, then running costs such as hosting
Main limit
Needs a scoping call first, and suits companies of 50 or more employees
Best for microsoft companies with a large portfolio of apps
OutSystems ranks third for Microsoft companies. It is the choice when IT has a long list of business apps, developers to build them and a wish to govern all of it on one platform. It ranks below Power Apps here because it is a second platform and a second contract, with a price that is quoted and not published, and it starts at 100 internal users.
Watch for. Price depends on application objects, end users and add-ons. Ask for the estimate against the apps you plan to build.
How it charges
Quoted by app size, end users and add-ons
Main limit
Price rises with app size, user count and add-ons, and is quoted.
Best for developers building tools on databases outside Microsoft
Retool is fourth. A Microsoft company still has databases and APIs that are not Microsoft, and Retool is sold for connecting internal tools to those quickly. It ranks fourth for this question because single sign-on is listed only for Enterprise, and a Microsoft company will expect staff to sign in with their Microsoft accounts from the start.
Watch for. Budget for the Enterprise plan if single sign-on is a requirement, and note that it is custom priced.
How it charges
Per builder and per internal user, billed yearly or monthly
Main limit
SSO, SCIM, Git source control and granular roles are Enterprise only.
Best for microsoft companies that want a prototype outside IT queues
Lovable ranks fifth. A business unit in a Microsoft company may choose it to get a working prototype without waiting for IT, and the Business plan adds single sign-on and role-based access for the workspace. It ranks low on this list because what it produces runs outside the Microsoft estate, so IT will have a new place where company data is stored.
Watch for. Agree with IT where the prototype may go and what data it may hold before the first prompt is sent.
How it charges
By credits, not seats, in monthly tiers
Main limit
SSO is Business only. Audit logs and SCIM need Enterprise.
Best for front-end teams that deploy on Vercel and not on Azure
v0 is sixth for a Microsoft company. It drafts interfaces and ships them to Vercel projects, so it fits a team that already deploys on Vercel. A company committed to Microsoft tooling gets less from it, because v0 roles cover only the v0 web app and everything else follows the member Vercel role. That is one more permission system for IT to manage.
Watch for. SAML SSO and role-based access are listed only under Enterprise, which is custom priced.
How it charges
Per user, monthly, with credits per user, Enterprise custom
Main limit
SAML SSO and role-based access are Enterprise only.
We ranked for a company of 50 or more employees that uses Microsoft 365 and Azure for mail, files and identity. Fit with that estate counted first, then how licensing behaves when an app is used widely, then how much new administration each option adds for IT.
Questions buyers ask
Do we need Power Apps Premium to run an app in production?
Microsoft's licensing pages say running apps in production needs a Premium license or the pay-as-you-go meter. The free Developer Plan is for building and testing only.
What does Dataverse storage cost as apps grow?
Each Premium license adds 250 MB of Dataverse database and 2 GB of file storage to a pool shared across the tenant. Extra database capacity is billed per GB a month, on yearly billing. Check the current figures with Microsoft before you plan around them.
Can a custom app use our Microsoft sign-in?
Yes, an app Black Badger builds can use Microsoft sign-in, so staff use the accounts they already have and IT keeps control of who has access. Nobody gains another password.
