StackPost Bridge
An indie cross-poster that publishes one video or carousel to many short-form accounts for a flat monthly price.
What it actually does
Post Bridge is built for posting the same short-form clip everywhere: you upload a video or carousel once and it pushes to up to 15 connected accounts across TikTok, Instagram Reels, YouTube Shorts, X and other networks.
Pricing is flat rather than per channel. The base Creator plan covers 15 accounts for $29/mo with unlimited scheduled posts and bulk video scheduling; the Pro plan adds unlimited accounts and team invites.
It is a publisher, not an analytics suite. There is effectively no reporting, so you check performance natively on each platform. A public API is available as a low-cost add-on.

- Unlimited scheduled posts, bulk video scheduling and carousels on the base plan
- Public API available as a cheap $5/mo add-on for automation
- No analytics, so you cannot see what worked without checking each platform natively
