Introducing Posthive: Schedule posts to multiple platforms at once
I was managing five social accounts across Bluesky, Threads, Instagram, LinkedIn, and Mastodon. Every morning I'd write the same post, tab-switch five times, paste it in each composer, tweak the character count, and finally hit publish — one by one. It was boring, error-prone, and ate 20 minutes of my morning.
So I built Posthive.
What Posthive does
Posthive is a single composer where you write once and schedule to all eleven platforms: Bluesky, Threads, Instagram, LinkedIn, Mastodon, YouTube, Facebook Pages, Pinterest, Telegram, Nostr, and X. Pick a time, hit Schedule — done. The post goes out at the exact second you chose, handled by a BullMQ job queue that retries automatically if a platform hiccups.
The features that shipped at launch
Here's what's live today:
- ✓Multi-platform scheduling — Bluesky, Threads, Instagram, LinkedIn, Mastodon, YouTube, Facebook Pages
- ✓Instagram Reels, Stories, and carousels (up to 10 images)
- ✓YouTube Shorts and regular videos with dedicated title/description fields
- ✓Drag-to-reschedule calendar — see your whole content week, drag posts to new slots
- ✓First comment automation — fire a reply the moment your post goes live
- ✓Per-platform overrides — different text per network without creating separate posts
- ✓Post templates — save formats you use repeatedly, load them in one click
- ✓Bulk CSV scheduling — upload a spreadsheet, schedule hundreds of posts at once
- ✓Full REST API — schedule posts programmatically from agents or scripts
- ✓Self-hostable — AGPL-3.0, run your own instance with Docker + Postgres + Redis
Bulk CSV — the hidden power feature
My favourite thing we built is bulk CSV scheduling. Create a spreadsheet with columns for date, text, platforms, optional first comment, and image URLs — then upload it. Posthive validates every row instantly and shows a preview table before scheduling anything. Bad date? Shows an error. Instagram row missing an image? Caught. You can even write !instagram in the accounts column to exclude a platform for that row without affecting others.
For social media managers running campaigns across multiple clients, this alone saves hours per week.
What's coming next
The backlog is full. Recurring posts, AI caption assist, post analytics, outbound webhooks, and multi-user team workspaces are all queued up. We're shipping fast — follow along on Bluesky or check the docs for what's live.
