Meta Business Suite

The official, free management platform from Meta for Instagram and Facebook. It centralizes publishing, messaging, and analytics for both platforms, making it indispensable for businesses. Its deep integration provides reliable scheduling, ad creation tools, and unified inbox management. While its interface can be clunky and advanced analytics are limited compared to third-party tools, its zero-cost and direct API access make it the foundational tool for most business accounts.

It's best for those who prioritize managing both Instagram and Facebook from a single, official dashboard.
