Meteor, or MeteorJS, is a partly proprietary, mostly free and open-source isomorphic JavaScript web framework[3] written using Node.js.

[5] Meteor raised an additional $20M in Series B funding from Matrix Partners, Andreessen Horowitz and Trinity Ventures.

[9] During the next few months, and with the help of large investments from Andreessen Horowitz and endorsements from high-profile figures in the startup world,[9] Meteor steadily increased its user base.

Particularly after receiving large amounts of venture capital in its Series B funding round, Meteor acquired and integrated several other startups into its core product.

In October 2019, the Meteor.js open source framework and Galaxy Hosting Products were purchased by Tiny Capital and renamed Meteor Software.
