Can I vibecode Postiz?
// buildable in a weekend, but real gaps stay open
The core loop (compose, queue, cron tick, publish) is one-shottable for networks with open APIs like Mastodon, Bluesky, and Telegram. What you cannot one-shot is the reason schedulers exist as products: OAuth apps for Instagram, LinkedIn, TikTok, and X are approval-gated or paid, and keeping 28+ integrations alive as platforms change policies is permanent maintenance. Postiz is also fully open source, so the honest DIY move for the full feature set is self-hosting it rather than rebuilding it.

Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Compose posts into a slot-based queue, publish them on schedule to open-API networks via per-network adapters, and log outcomes.
what you need
- OAuth/API access per social network
- always-on box for the scheduler
- database
- media storage
Rare case where the SaaS is its own prior art · self-host it instead of rebuilding it.
The prompt
A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.
Build me a personal social post scheduler to replace Postiz. Requirements:
- Node + Express + better-sqlite3; a localhost page with a compose box,
image attach, and the queue ordered by send time.
- Three targets: Mastodon (access token), Bluesky (app password via
@atproto/api), and a Telegram channel (bot token). Creds in .env, one
small adapter file per network so a fourth is addable later.
- Slot-based queueing: I define posting times per weekday in my timezone
and new posts fill the next free slot; a post can also be pinned to an
exact datetime or duplicated across networks with per-network text.
- A node-cron tick every minute publishes due posts, marks each row sent
or failed, retries failures 3 times with backoff, and marks before
sending so nothing ever double-posts.
- Per-network character counter in the composer; attached images stored
in media/ next to the database, resized to each network's limits with
sharp.
- A history page of the last 100 sent posts linking to the live posts.
- Runs on my always-on box; localhost only, no accounts, no telemetry.
- Out of scope: Instagram, LinkedIn, TikTok, and X (approval-gated or
paid APIs, say so in the README), analytics, teams, and AI features.
- README: getting a Mastodon token, a Bluesky app password, and a
Telegram bot token.Curated prompt: written and reviewed by hand for this app. In English on purpose — it is the language coding agents work best in.
What you lose
- 28+ maintained channel integrations
- pre-approved platform OAuth apps (Instagram, LinkedIn, TikTok)
- per-network post previews
- analytics
- team approvals and collaboration
- AI content assistance
Why people still pay
The hosted version ships with platform-approved OAuth apps, so connecting Instagram, LinkedIn, or TikTok is a click instead of a developer-app review process. Social APIs break and change terms constantly; paying outsources that upkeep plus analytics, teams, and AI features.

Who has already built it
Starting from here is still vibecoding: the prompt is for when you want it exactly your way.
- Postiz (open source) (opens in a new tab) — The app itself is AGPL open source and self-hostable, which is the shortest path to the full feature set. (alive)
