Building in public · free at launch

Post once.
Show up everywhere.

Radium Social schedules your week of content and cross-posts one vertical video to Instagram Reels, YouTube Shorts, and Facebook Reels — in a single click. A calm, fast tool for creators who'd rather be creating.

No spam. One email when your invite is ready.

One composer · five platforms

The daily grind

Five tabs. The same caption, rewritten five times. Every single day.

Constant context-switching between Instagram, LinkedIn, X, Facebook and YouTube.

Re-uploading the same vertical video to Reels, Shorts and Facebook Reels — by hand, every time.

No single place to batch-plan and schedule a whole week of posts.

Existing tools are either too expensive, or too limited to be useful for free.

What Radium does

Three things, done well. No bloat.

Media library + auto-post

Upload your photos and clips once. Set simple rules and let Radium auto-schedule them as posts or stories.

Drag-drop scheduling

Plan a whole week on one calendar. Drag to reschedule, track every post from draft to published.

Also from day one

Posting is only half of it.

Reply to comments in one inbox

Every comment across your accounts lands in a single inbox — read, reply, and moderate without opening five apps. Sentiment is flagged automatically so you see what needs you first.

Analytics & insights

Reach, engagement and follower growth for every post and platform, in one clear view. Know what's working without exporting a single spreadsheet.

From the maker

"I've used Hootsuite and Sprout Social for years and paid for pain. Radium is the calm, fast, honestly-priced tool I always wanted — built solo, in public, from Delhi."
