Where SkedCast fits#
SkedCast is not open source. Its /v1 REST API and MCP server solve the same problem these wrappers do, talking to each platform correctly, for 11 platforms behind one versioned contract.
- Scheduling, pacing and multi-account fan-out are built in instead of left to your own code.
- API and MCP access are part of the plans that include them (see pricing).

FAQ
- Is there a good open-source alternative to Buffer or Hootsuite?
- Postiz (gitroomhq/postiz-app) is one: a self-hostable, AGPL-3.0 multi-platform scheduler with its own public API.
- Is instagrapi safe to use in production?
- Not for a supported integration. instagrapi uses Instagram's private API, which Instagram can change without notice and which its terms may not allow. The supported route is Instagram's Graph API content-publishing endpoints, or a managed layer such as SkedCast.
