Preflight
Social scheduler that checks every post first
Preflight is a social media scheduler that checks every post against each network's real publishing rules before it leaves, so a post never fails halfway through a list of networks. It publishes one post to 12 networks: YouTube, TikTok, Instagram, Facebook, Threads, LinkedIn, Pinterest, Bluesky, Mastodon, Telegram, Discord and Tumblr. The same check runs in the composer, the REST API and a hosted MCP server, so Claude, ChatGPT or Cursor can draft, validate, schedule and publish posts. Free plan, no card; paid plans from $13 a month.
Features
Per-network rule check before every post
Use Cases
Agencies checking client posts before they go out

Hi, I'm Adam, I built Preflight. I kept watching scheduled posts fail halfway through a list of networks: a Bluesky post over 300 graphemes, an Instagram image in the wrong ratio, a TikTok video longer than the account allows. The scheduler said "scheduled" and the network said no, usually at 3 a.m. Preflight runs the same check in the composer, the REST API and the MCP server, using each network's real rules (counted the way the network counts), before anything is sent. It publishes to 12 networks, clients can approve posts from a link without an account, and Claude or ChatGPT can schedule through the MCP server on every plan, Free included. I'd love to hear which network's rules have burned you most. I'll answer every comment.
