Custom Web Application in Chelsea, Massachusetts — Questions
Do you work with Chelsea businesses that already have a site?

Often, yes. Plenty of Chelsea projects are rebuilds — the content and brand carry over, the code underneath is replaced, and the URLs are mapped so existing rankings follow.

How do I know the Chelsea site is actually fast once it is live?

Every build is measured on Google Lighthouse before launch and again after go-live. The target is 100, and it is a number you can verify for your Chelsea site yourself rather than take on trust.

How long does a Chelsea project take?

Most Chelsea sites launch within about a month, including design, build, content, and deployment with SSL and caching configured.

What happens after my Chelsea site launches?

You own the code and the domain outright. Hosting is yours to choose, and most Chelsea clients handle day-to-day edits themselves through the editable sections.
