PostOctopus in 2026: $15/mo for 2 Platforms — Worth It?

PostOctopus (also known as Postopus) is a visual editor built around LinkedIn and X/Twitter. Its pitch is simple: write once, preview how your post looks on each platform, and schedule it. The editor is clean, and the LinkedIn carousel creator is a nice touch for anyone who publishes document-style content on LinkedIn regularly.

But the platform limitation is the dealbreaker for most creators. PostOctopus only supports two platforms — LinkedIn and X. If you also post to Instagram, TikTok, Facebook, YouTube, Pinterest, Threads, or Google Business Profile, you'll need a second tool. posterly supports all 10 of those platforms from a single dashboard for $7/month — half the price of PostOctopus.

The math doesn't work in PostOctopus's favour. At $15/month you're paying $7.50 per platform. On posterly's Starter plan you connect 5 accounts across any of 10 platforms for $7/month — that's $1.40 per account. Even PostOctopus's lifetime deal at $249 only locks you into two platforms forever, while the social media landscape keeps expanding.

PostOctopus also has no AI features. You write every caption, every carousel headline, every first comment by hand. posterly's AI generates captions from scratch with brand-voice learning, suggests optimal posting times, creates images and videos through AI Studio, and lets you schedule entire campaigns through natural-language chat with the AI Agent. These features are included on every plan — not paid add-ons.

Where PostOctopus does well is its real-time preview — you see exactly how your post will render on LinkedIn and X before publishing. posterly's Composer also shows platform-specific previews and character counts, but PostOctopus's side-by-side view is slightly more polished for those two specific platforms.

Switching is instant. Connect your LinkedIn and X accounts to posterly and start scheduling. There's no content to migrate — your published posts stay on the platforms regardless of which tool created them.
