Web App & Power Platform Development
When off-the-shelf runs out, we build what's next.
Custom web and mobile applications, Power Platform solutions, and code-first Dynamics extensions — designed, built, and supported by the same team that knows your Dynamics and AI stack.

Why it matters.

- One accountable team, from UX to deployment to support.
- Apps that plug straight into your Dynamics data and AI, because we built those too.
What we deliver
In every engagement.
Why Cosmic
What sets us apart here.
We're not a CRM shop that dabbles in code — building software is a first-class practice here.
Custom PCF controls, plug-ins, and full web apps are our home turf.
Because we also own your Dynamics and AI work, your custom app is a native part of the system, not a bolt-on.
Built on Azure
Everything we build runs on Azure infrastructure we design, secure, and manage — hosting, environments, monitoring, and cost control included, with optional managed-services support after launch.
