The dominant factor is not the choice of framework — it is almost always uncertainty. Every ambiguity in the specification becomes a contingency in the estimate.

Ask each bidder to list every external system, since this is the usual source of overruns. Non-functional requirements can easily double the number. A tool used by a handful of staff is a very different build from the same idea serving thousands of external customers. Security reviews, uptime targets, performance under load, audit logging and localisation each add measurable effort. State them early or expect them priced as extras.
