FAQ

Web Apps in San Francisco: common questions.

What kind of web apps do you build?

Booking and scheduling systems, customer portals, internal dashboards, calculators, and other custom tools that go beyond a brochure website. If your business runs on a workflow a template cannot handle, that is exactly what we build.

Do you work remotely with businesses outside Rhode Island?

Yes. We are based in Providence, RI and build for clients across the US and Canada, working remotely by phone, video, and email. Web app projects run smoothly from anywhere.

Do I own the application and its code?

Yes. The code, the hosting accounts, and every integration are set up in your name and handed over at the end. You own the app outright and are free to host, extend, or move it however you like.
