In our clients’ words

Apps By TAP made our minimum viable product website in record time (weeks) for an upcoming tradeshow which was pivotal to have in place! Travis was a real joy to work with and is definitely a unique software developer who really leaned into our business to learn what was necessary in order to ensure that the website delivered what our customers needed. Thank you Apps By TAP!!

Henry G.Bim-Plugins.com

Apps By TAP was superbly helpful in creating my business website. Their expertise brought my ideas to life, and since launch I’ve seen major improvements in traffic, inquiries, and feedback. They asked the right questions to capture my vision and deliver exactly what I wanted.

Good questions

Should we use a site builder or a custom web application?
If you need a marketing site your team can edit, a site builder such as Wix Studio is fast and affordable, and we pair it with technical and local SEO. If you need accounts, payments, dashboards or integrations, we build a custom application with Blazor and ASP.NET Core on Azure.
What is Blazor, and why do you use it?
Blazor is Microsoft’s framework for building interactive web apps in C#. With Blazor Auto Render, pages load quickly from the server and then run in the browser, and a single language covers both the interface and the API.
Can you integrate payments and third-party data?
Yes. We’ve integrated Stripe Checkout, Stripe Billing, Stripe Connect payouts and Plaid bank data. Card and bank details never touch your servers, and secrets are stored in Azure Key Vault.
How quickly can you launch an MVP?
It depends on scope. Bim-Plugins.com went from kickoff to a working marketplace in weeks, in time for the client’s trade show, with signing, licensing and payouts in place.
Will our site rank on Google?
We build SEO in from the start: structured data, fast pages, clean URLs and Search Console, plus Google Business Profile work for local businesses. ScrubDucts.com now ranks #1–2 in every city it serves.
Who hosts and maintains the site after launch?
We can host on Azure or on the platform you already use, and we stay on for updates, new features and monitoring. Site-builder projects are set up so your team can edit content themselves.
