FocusReactive has developed a CMS migration estimator tool that automates cost assessment for website migrations. The tool addresses common estimation failures that occur when teams rely solely on page count rather than underlying technical complexity. The estimator combines automated site crawling with manual engineering review to analyse content architecture, component variability, integrations, frontend implementation and data quality. It identifies risk factors including legacy integrations, custom business logic and incomplete content inventories that typically cause budget overruns. The tool crawls websites to identify structure, technologies and integrations, counts unique components and content patterns, and detects potential risk areas. It produces detailed migration roadmaps with week-by-week delivery timelines and effort estimates broken down by category. The hybrid approach aims to provide more accurate project scoping than traditional surface-level assessments.
