It mostly has a neolibaral foundation, and secondarily a governance and NGO ethos.
Anti-Globalism in the 1990's was by the Left, and they were against the WTO and mostly neoliberal world order.
Anti-Globalism today is much more complicated issue, but with the more popular versions being more or less Nationalist, anti-UN/WHO/Multilaterialism.
Personally - I think there are very good arguments on all sides of this subject and it's sad that it's ideologically aligned.
Global neoliberalism has brought zillions out of poverty, but has wicked externalizations and a lot of inequality.
Globalist institutions have a certain kind of individual corruption (think FIFA) and are also subject to the completely antithetical influences of bad actor states (think Saudi Arabia on Human Rights) etc. and finally, very susceptible to ideological institutionalization, elitism and creeping, ineffectiveness and bureaucracy.
Yet at the same time there are some parts of some orgs that are super essential. Like the WHO right now and probably the IPCC for a few reasons.
