5 Apps That Support Cross Posting on Instagram and Facebook Simultaneously (2026)

5 Apps That Support Cross Posting on Instagram and Facebook Simultaneously

You post a video to Instagram.

Then you log into Facebook. Upload the same video again. Write the caption again.

10 minutes wasted.

Now multiply that by 5 posts per week.

That's 50 minutes/week of copy-paste BS.

Here are 5 apps that let you post to Instagram AND Facebook (and more) with one click.

Why Post to Instagram + Facebook Simultaneously?

1. Time Savings

Manual: 10-15 mins per post
Simultaneous: 2-3 mins per post

Save 40+ mins/week.

2. Audience Overlap

Your Instagram audience ≠ Your Facebook audience.

Instagram: Younger (18-34)
Facebook: Older (35-65)

Same content. Different demographics. 2x reach.

3. Algorithm Benefits

Both platforms (owned by Meta) reward consistent posting.

Posting to both = 2x algorithmic opportunities.

4. One Upload, Multiple Placements

Upload once. Get:

Instagram Feed
Instagram Reels
Facebook Feed
Facebook Reels
Facebook Stories (if you want)

That's 4-5 placements from one upload.

1. Socialync — Best for Creators (What I Use)

Platforms Supported:

Instagram (Feed + Reels)
Facebook (Feed + Reels)
TikTok
YouTube
Twitter
LinkedIn

Why It's #1 for Instagram + Facebook:

Features:

✅ Upload video once, posts to both Instagram + Facebook
✅ Custom captions per platform
✅ Supports Reels on both platforms
✅ Schedule posts in advance
✅ No quality loss on videos
✅ No watermarks

Pricing:

Free: 5 posts/month (all platforms)

My Experience:

I used to spend 15 minutes posting to Instagram + Facebook separately.

Now I upload to Socialync once. Custom captions for each. Click post to both.

Takes 3 minutes.

Plus, I'm also posting to TikTok, YouTube, LinkedIn, and Twitter in the same 3 minutes.

6 platforms. 3 minutes. $10/month.

Best For: Creators who want Instagram + Facebook + other platforms in one tool.

2. Meta Business Suite — Best Free Option (With Limits)

Platforms Supported:

Instagram
Facebook
(That's it. Only Meta platforms.)

Why It's #2:

Features:

✅ Completely free
✅ Direct integration (owned by Meta)
✅ Schedule posts
✅ Insights dashboard
✅ Post to Instagram + Facebook simultaneously

Limitations:

❌ Complex interface
❌ Desktop-only for Reels
❌ No TikTok, YouTube, LinkedIn, Twitter support
❌ Video upload limits
❌ Scheduling bugs

My Experience:

Meta Business Suite is free, which is great.

But the interface takes some getting used to. Video uploads can be unreliable. Scheduling doesn't always work perfectly.

It's fine if you ONLY post to Instagram + Facebook and are patient with the experience.

But if you want other platforms, look elsewhere.

Best For: Businesses that only use Meta platforms and want free.

3. Later — Best for Visual Planning

Platforms Supported:

Instagram (Feed + Reels + Stories)
Facebook (Feed + Reels)
TikTok
Twitter
LinkedIn
Pinterest

Why It's #3:

Features:

✅ Beautiful visual calendar
✅ Drag-and-drop scheduling
✅ Instagram + Facebook support
✅ Link in bio tool included
✅ Hashtag suggestions

Limitations:

❌ Expensive ($25/month starting)
❌ Video upload can be slow
❌ Limited free tier (10 posts/month total)
❌ Desktop-focused (mobile experience is limited)

My Experience:

The visual calendar is gorgeous. Great for planning content.

But uploading videos is a pain. And $25/month is steep for what you get.

If you're Instagram-first and love visual planning, it's solid.

For video creators, Socialync is simpler and cheaper.

Best For: Instagram influencers who prioritize planning over posting speed.

4. Buffer — Best for Analytics

Platforms Supported:

Instagram (Feed + Reels + Stories)
Facebook (Feed + Pages)
Twitter
LinkedIn
Pinterest
(No TikTok or YouTube natively)

Why It's #4:

Features:

✅ Deep analytics dashboard
✅ Post to Instagram + Facebook
✅ Browser extension for quick sharing
✅ Calendar view

Limitations:

❌ No TikTok or YouTube support
❌ Expensive ($36/month for 6 channels)
❌ Video uploads are slow
❌ Interface feels dated

My Experience:

Buffer is great for data nerds who want analytics.

But no TikTok or YouTube? That's where growth is happening in 2026.

And $36/month vs Socialync's $10/month for MORE platforms? No thanks.

Best For: Brands that prioritize analytics over video and don't use TikTok/YouTube.

5. Hootsuite — Best for Agencies

Platforms Supported:

Instagram
Facebook
TikTok
YouTube
Twitter
LinkedIn
Pinterest
15+ more

Why It's #5:

Features:

✅ Supports basically every platform
✅ Advanced team workflows
✅ Client management
✅ Bulk scheduling
✅ White-label reports

Limitations:

❌ Expensive ($99/month starting)
❌ Steep learning curve
❌ Overkill for solo creators
❌ Video upload limits on lower tiers

My Experience:

Hootsuite is a beast. It can do everything.

But it's like buying a semi-truck to drive to the grocery store.

If you're managing 20 client accounts, sure.

If you're a solo creator? You're paying $99/month for features you'll never use.

Socialync does Instagram + Facebook + 4 more platforms for $10/month.

Best For: Agencies managing multiple client accounts.

Advanced Tips for Instagram + Facebook Posting

Tip #1: Customize Captions (Even If Video Is Same)

Instagram audience ≠ Facebook audience.

Instagram users want:

Emojis
Hashtags
Call-to-action ("Save this!")
Relatable captions

Facebook users want:

Stories
Community feel
Questions
Tag-a-friend prompts

Same video. Different captions. Better engagement.

Tip #2: Post at Different Times

Instagram peak: 11am-1pm, 7-9pm EST

Facebook peak: 1-3pm EST

Don't post to both at 9am.

Better:

Instagram: 12pm
Facebook: 2pm

Use Socialync's scheduling to auto-post at optimal times.

Tip #3: Use Instagram Reels, Not Feed Posts

Reels get 2-10x more reach than feed posts on Instagram.

On Socialync:

Select "Reels" for Instagram
Select "Reels" for Facebook
Same video, posted as Reels on both

Result: Maximum reach on both platforms.

Tip #4: Don't Ignore Facebook Just Because "It's Dead"

"Nobody uses Facebook anymore!"

Wrong.

Facebook has 3 billion monthly active users. Instagram has 2 billion.

Facebook is bigger.

Your Gen Z audience? They're on Instagram.

Your parents, aunts, uncles, buyers over 35? They're on Facebook.

Post to both. Capture both demographics.

Tip #5: Track Which Platform Performs Better

After 30 days, check your analytics.

Instagram getting more views? → Create bonus Instagram content
Facebook getting more conversions? → Create bonus Facebook content
Both performing well? → Keep cross-posting to both

Use data to inform your strategy.

Common Mistakes When Posting to Instagram + Facebook

Mistake #1: Using the Exact Same Caption

Instagram users expect hashtags and emojis.

Facebook users don't.

Fix: Customize captions. Takes 30 extra seconds.

Mistake #2: Posting Only to Instagram Stories

Instagram Stories don't cross-post to Facebook Feed easily.

Fix: Use Reels (they cross-post perfectly to both platforms).

Mistake #3: Forgetting to Check Facebook

Most creators obsess over Instagram analytics. They forget to check Facebook.

Fix: Check both weekly. You might be surprised by Facebook performance.

Mistake #4: Not Using Facebook Reels

Facebook Reels is Meta's push to compete with TikTok.

The algorithm is HEAVILY pushing Reels right now.

Fix: Always post as Reels on both Instagram + Facebook.

For most creators: Use Socialync

Why:

✅ Supports Instagram + Facebook + 4 more platforms
