Switching from Buffer to Mixpost

Run the official `inovector/mixpost-pro-team` (or CE) image. Connect each social channel through Settings → Channels → Add (OAuth flow per platform). Buffer queue export (no native — pull via CSV manually) re-imports through the API. MixPost CE covers solo use; Pro adds the multi-workspace + team approval surface that Buffer for Teams targets.

Good fit for: Solo creators and small businesses who prefer a one-time license to ConvertKit/Buffer's recurring channel-based pricing.
Weak at: PHP/Laravel stack means more moving parts (queues, supervisor) than Postiz; Pro features behind paid license.
License note: Community Edition is MIT; Pro Edition adds team workspaces, link-in-bio, and content calendar features under a one-time license.
