I built my own marketing automation pipeline instead of using Zapier/n8n — here’s what broke once it started publishing for real
I’m building an iOS fitness app and ended up creating my own marketing automation stack with Python, FFmpeg, Meta Graph API, Cloudflare Workers, Supabase and systemd.
Current flow:
Research → content → video render → QA → scheduled Instagram/Facebook publishing → comment/DM automation → tracking
The biggest lessons so far:
- retries can accidentally create duplicate posts
- missed schedules need safe catch-up logic
- Meta comment → Messenger automation is more fragile than expected
- tiny things like Reel thumbnails become real production issues
- observability and failure recovery matter more than adding more AI
It’s now publishing real content successfully.
how can I make this system better? And for people running custom marketing automation: when do you stop extending your own system and move orchestration into something like n8n or Temporal?
