Good fit for Fediverse-first creators whose audience is on Mastodon/Bluesky and who want zero extra infrastructure.

Weak at Single-channel — won't post to Instagram, LinkedIn, or X without bridges; per-channel formatting is missing.

Replaces these SaaS

Buffer · Social media scheduling + analytics
If your Buffer use is single-channel (just X / Mastodon / Bluesky bridged via Bridgy Fed), Mastodon's built-in scheduled posts cover it. Compose post → set the schedule date → submit; Mastodon stores it and publishes at the scheduled time. Pair with Bridgy Fed (brid.gy) to fan out from your Mastodon post to ATProto/Bluesky followers automatically.
Twitter / X · Microblogging social network
Use the official docker-compose at docs.joinmastodon.org. Twitter archive request (Settings → Your account → Download an archive of your data) yields a `tweets.js`. Run a community converter like `tweet-archive-to-mastodon` or `mastodon-twitter-archive` to post (or import as drafts) historical tweets respecting timestamps. Import follows from Twitter via the Movetodon helper if any of your follows have linked their Mastodon account in their X bio.
