Foundry

Foundry posts Instagram Reels, TikToks and YouTube Shorts from iPhones connected to a Mac. It uses the official mobile apps rather than APIs, cloud phones or rented accounts, and accounts are priced per iPhone rather than per account.

An agent queues the video, caption, account and timing through a command-line tool and agent skill used with Claude Code, Codex or Cursor. Foundry drives the app on the phone, reads the caption back before sharing, checks that the post went live, and writes a receipt with the result. It also handles common interruptions, retries some failed posts and avoids double-posting.
