A web app is software people log into: accounts, data, and a job they do every day. A marketing site explains the company. Most teams need the site first and the app when the workflow is clear.
What the first version includes
- The one workflow users repeat, not every idea from the brief
- Accounts, the main screens, and a way to see if it worked
- A deploy you can open on a phone, with room to add the next feature
We build that on Next.js and Node, then keep the same team for the next release. If you are choosing a web app development company, ask to see a weekly build, not a monthly report.
