React vs Vue: Choosing a Frontend Framework

Maintenance cost is driven mostly by hiring availability and code quality, not license fees, since both are free and open source. React often has a slight edge because its larger talent pool makes it easier and cheaper to replace departing engineers or bring in help. That said, a clean Vue codebase maintained by a stable team can be very economical.

Yes, but treat it as a significant rewrite rather than a simple upgrade, because the component models and ecosystems differ. Migrations are usually done incrementally, one section or feature at a time, to limit risk. Because migration is expensive, it is worth investing effort in the initial framework decision.

Neither framework is inherently better for SEO. Search performance depends on rendering strategy, and both React (via Next.js) and Vue (via Nuxt) support server-side rendering and static generation that produce SEO-friendly pages. The wrong configuration, not the framework, is what usually hurts search visibility.

Svelte, Solid, and others offer genuine technical advantages and smaller bundle sizes, and they can be excellent for specific projects. For most B2B products, however, their smaller talent pools and ecosystems introduce hiring and maintenance risk that React and Vue do not. If long-term staffing certainty matters, the safer choice is usually one of the two established options.

An experienced JavaScript developer is typically productive within a few weeks in either framework, with Vue often feeling slightly faster to pick up. Reaching senior-level mastery of patterns, performance, and architecture takes longer in both. Budget for a ramp-up period whenever you introduce a framework to a team that is new to it.
