Deep Dive: Switching from PostFast to Postiz
Trade-offs, installation & data architecture
What you trade away
Postiz matches much of the feature surface, but its database, queue, Temporal and credential stack becomes your responsibility.
How to deploy Postiz
Hosted signup, or Docker Compose for self-hosting.
What it takes to run
Hosted use is straightforward; self-hosting requires Docker, social OAuth apps, and a PostgreSQL, Redis and Temporal stack.
Where your data lives
PostgreSQL holds application data; Redis and Temporal support jobs; media is stored locally or in Cloudflare R2/S3-compatible storage.
Why fork Postiz instead of vibe-coding a PostFast clone?
The core loop is the one every scheduler shares and it is genuinely one-shottable: a compose box, a slot queue, a cron tick, one adapter per network. Two things sit outside what a coding agent hands you in a session. The first is paperwork. Only Bluesky and Telegram give you working credentials on signup; the other nine of PostFast's eleven destinations wait behind Meta App Review for Instagram, Facebook, and Threads, a TikTok audit before an app may post publicly rather than to a private draft, YouTube's default 10,000-unit daily quota against 1,600 units per upload, approval flows at LinkedIn, Pinterest, and Google Business Profile, and X, where the free tier is capped tightly enough that real volume means paying. The second is video. Every platform enforces its own container, codec, aspect ratio, duration, and size rules, so anything past text and a JPEG turns into a transcode pipeline with somewhere to actually run the jobs and a retry story for the upload that dies at 90 percent. Build the text-and-image version for the two open networks in a sitting; the rest is review forms and a transcode queue.
