We were paying $200+/month managing social media for our startup — Planable, Buffer, separate AI tools. So I built SocialCue.
It's a self-hosted content calendar with a proper client approval workflow. Clients get their own login, see only their content, approve posts directly. Approved posts auto-publish to Buffer at the scheduled time.
6 PHP files. Any web host. No database. Live demo at socialcue.eu/demo
