PostDock is a self-hosted social media scheduler for creators, agencies, and small teams who are done renting their posting queue. Buffer charges $6 per channel per month — five channels for three years is $1,080. PostDock is the same core workflow (compose, preview, schedule, queue) for $49 once, running on your machine with your API keys and your data in a SQLite file you can back up.

• 5 pluggable channel drivers: X/Twitter, Facebook Page + Instagram Business, LinkedIn, Mastodon, and a generic Webhook (HMAC-signed) for Zapier/Make/n8n — your escape hatch to every other network
• Composer with per-channel character counters (280/500/2200/3000) and live preview cards per network
• Timezone-aware scheduling with month-calendar and list queue views
• Honest statuses: scheduled → publishing → published/failed with the actual API error, plus a “Retry failed” button that only re-hits failed channels
• Drafts + content recycling — evergreen posts re-queue every N days
• In-app step-by-step setup guides for every channel driver
• Crash-safe in-process scheduler, every attempt logged
• Unlimited channels, unlimited scheduled posts

Runs as a Windows desktop app or on a $5 VPS (Docker included).
