Pricing breakdown
Buffer uses per-channel pricing, which scales fast. A creator publishing to 8 platforms (YouTube, TikTok, Instagram, Facebook, X, LinkedIn, Pinterest, Threads) on Buffer's Essentials plan pays $6 × 8 = $48/month. The same setup on Zync's Essentials plan is $9/month flat, covering 10 connected accounts.
For agencies managing 20+ client accounts, Buffer's Team plan ($12/channel) runs $240+/month. Zync Pro is $19/month for unlimited accounts. Annual savings vs Buffer at 20 channels: $2,652/year.
Buffer's free plan allows 10 scheduled posts per channel (30 total for 3 channels). Zync's free plan caps at 5 scheduled posts total but does not expire and includes the same 3 channels forever.
Feature differences that matter
Video-first features: Zync was built around video cross-posting. Magic Crop automatically converts a 9:16 vertical video into 1:1 (Instagram feed), 16:9 (YouTube), and back — without re-uploading. Buffer does not offer aspect-ratio conversion; you have to pre-render each format yourself.
AI captions: Both have AI text generation. Only Zync transcribes spoken audio into burned-in or platform-native captions in 30+ languages. Buffer's AI Assistant rewrites text but does not touch video.
Platform breadth: Zync supports niche platforms (Vimeo, Dailymotion, Tumblr, Telegram, Discord) that Buffer dropped or never added. If you cross-post to communities like Reddit or Discord, Buffer requires Zapier or manual posting.
Why Zync wins for solo creators and small teams
- Flat pricing. $9/month for 10 accounts beats per-channel pricing for anyone publishing to 4+ platforms.
- Video-native. If your content is video, Magic Crop + AI captioning save hours per week of re-editing and transcription.
- More platforms. 16+ vs 10 means fewer manual workarounds.
- EU data hosting. GDPR-by-default matters for European creators and agencies serving EU brands.
- No long-term contracts. Cancel anytime, downgrade anytime, free plan never expires.
When Buffer might be the better choice
Buffer has been around since 2010 and has deeper integrations with legacy enterprise tools (Salesforce, HubSpot pipelines). If your team already uses Buffer and you only publish to 2-3 platforms with text-first content (no video), the migration may not be worth it. Buffer also has a more established affiliate and partner ecosystem.
