Custom API & Backend Development FAQs
Where will the API be hosted?
Usually on Cloudflare's serverless platform for speed and low cost, or on your preferred cloud when required.
Is custom software worth it for a small business?
It is when a process costs you hours every week or limits growth and off-the-shelf tools do not fit. Many projects pay for themselves by eliminating double entry and errors.
Who owns the code?
You do. You get the source code, the data and admin access. No lock-in.
