Mastodon Scheduled Posts (built-in) vs Mixpost
Self-host pick — both replace Buffer (Social media scheduling + analytics).
Both Mastodon Scheduled Posts (built-in) and Mixpost self-host as a replacement for Buffer (Social media scheduling + analytics). Pick Mastodon Scheduled Posts (built-in) if you want the lighter footprint — 0min if you already run Mastodon, free — uses your existing mastodon instance. Pick Mixpost if you need solo creators and small businesses who prefer a one-time license to ConvertKit/Buffer's recurring channel-based pricing — 20min docker run (Laravel + MySQL + Redis) and $5-10/mo vps; pro license is one-time ~$200, no recurring.

Mixpost

Weak at:PHP/Laravel stack means more moving parts (queues, supervisor) than Postiz; Pro features behind paid license.
