Foundry

Foundry runs on your Mac and posts Instagram Reels, TikToks and YouTube Shorts from real iPhones you own, through the official apps. No APIs, no cloud phones, no rented accounts.

Your agent (Claude Code, Codex or Cursor) queues the clip and the caption. Foundry puts the clip in the phone's camera roll, opens the app on the right account, types the caption and reads it back before anything is shared. Then it checks the result and writes a receipt for every post.

It clears pop-ups on its own, retries a failed post 20 minutes later and never double-posts. Warm-ups are included on every account and passwords stay on the phone. Priced per iPhone, accounts are never counted, and every plan starts with 7 days free.

Our own iPhones run on it every day (live numbers on the homepage).

For app founders who would rather not run phones at all, the Launch is done for you: four of our iPhones post only for your app, 28 new accounts across TikTok, Instagram and X by day 28, and a new video every day on every warm account. Book 15 minutes at https://runfoundry.app/book.
