Schedule Threads posts and multi-part threads.

Free plan, no credit card. Paid plans include a 14-day free trial.

What you can post to Threads

Up to 500 characters, with up to 20 photos and videos (video up to 5 minutes).

Thread

Extra parts publish as replies, in order.

Why teams schedule Threads with PostBoost

One calendar for every channel

See Threads next to your other 14 channels and move posts when plans change.

One post, a version per network

Write once, then adjust the text for Threads without copying the post.

Know when a post fails

If Threads rejects a post, you see why and can retry it once it is fixed. A webhook can tell your code too.

Same idea, three networks

Start from one text and keep a version for Threads, X and Bluesky, each inside its own limit.

Threads on PostBoost in one paragraph

PostBoost schedules and publishes to Threads: post and thread. You connect it by signing in to Threads. Posts go out from the dashboard, from an AI agent over MCP or from the REST API, and each connected Threads account counts toward your plan's social accounts (Free: 3).
