The dominant factor is not the choice of framework — it is almost always how much is still undecided. Every ambiguity in the requirements is converted into padding in the estimate. A vendor that has no visibility into the edge cases will assume a pessimistic case. Spending a week on

Begin with relevant experience, not the length of the client list. Ask to see three or four case studies that match your stack, and then ask specifically which engineers actually built it. An honest provider will introduce you to the engineers. Evasive answers at this stage almost always mean you

Hiring in-house gives you the most control. The developers absorb your customers and your data model over time, and that knowledge stays in the building. The price is slow hiring and fixed overhead: hiring well is slow, onboarding adds several more weeks, and the cost keeps running through the quiet

The single largest cost driver is not the choice of framework — it is almost always how much is still undecided. Every ambiguity in the brief is converted into a contingency somewhere in the quote. A vendor that does not know the edge cases must assume the worst. Spending a
