Should I vibe-code or build my own Post Bridge clone from scratch?+
Our build verdict for Post Bridge is KINDA (the core, yes. the polish, no). The core loop (compose, queue, cron tick, publish) is one-shottable for networks with open APIs like Bluesky, Mastodon, and Telegram. What you cannot one-shot is the reason Post Bridge exists: one-click posting to TikTok, Instagram, YouTube, Facebook, Threads, Pinterest, LinkedIn, and Google Business Profile. Those APIs are approval-gated behind Meta App Review, TikTok's Content Posting API, YouTube quota, and business verification, which as an individual you often can't even qualify for. On top of that sits per-platform video transcoding, constant token-refresh babysitting, and an API plus MCP server so an agent can post for you. You can vibecode a personal cross-poster for the open networks in a sitting; you cannot vibecode the approvals.
What is the catch when switching from Post Bridge to Postiz?+
Postiz's broad API and MCP coverage comes with PostgreSQL, Redis, Temporal, storage and social credentials to operate.
