Ban-risk and rate-limit safety on Threads

Humanized posting delays

Threads rate-limits publish calls per hour; jitter keeps a multi-post day inside that envelope.

Official API only

Threads API via official Meta OAuth 2.0 (threads_content_publish). No scraping, no session cookies, no unofficial endpoints — the practices that actually get accounts suspended.

Compression before upload

WebCodecs re-encodes on your device — a 100 MB clip becomes roughly 12 MB — so Threads uploads finish fast and stay inside its size ceiling. Try the compressor.

Threads publishing questions

Specifics about limits, media and compliance when GentoPost posts to Threads.

What is the Threads character limit?

500 characters. GentoPost shortens the shared draft automatically and previews the result before sending.

Can I publish to Threads and Instagram from one draft?

Yes — one Meta sign-in covers both, and each gets its own tone and hashtag count.
