Channels overview
Every supported platform at a glance
OpenPost is built to publish natively to eight platforms. “Native” means the post arrives in the format the platform expects — a thread on X is a real thread, a carousel on Instagram is a real carousel. We never flatten formats to a lowest common denominator.

How OpenPost handles differences
Each platform has its own rules: character limits, media specs, hashtag behavior, mention format, link unfurling, video aspect ratios. OpenPost handles the translation in three ways:
- Composer warnings— if your post will be truncated or rejected on a specific channel, the composer tells you before you publish.
- Per-channel overrides— tap any channel tab in the composer to tailor the text, media, or link for that platform only.
- Automatic format conversion— we re-encode videos to each platform’s required codec, split threads into per-tweet calls, and generate carousel slides from long-form content.
