SocialKit vs Postly

Postly covers 10 of SocialKit’s 11 platforms: Instagram, TikTok, YouTube, Facebook, LinkedIn, X, Threads, Bluesky, Pinterest, and Google Business. Mastodon is the exception — it is not listed among Postly’s supported platforms, and its pricing page counts “10 supported” social networks (as of June 2026). SocialKit publishes natively to all 11, Mastodon included.

To be fair, Postly goes wider outside social media: Telegram messaging, WordPress blogs, email campaigns through services like Mailchimp and Brevo, and its own Bio Pages. If you need one tool to push content to every kind of channel, that breadth is real. The catch is the meter: on Postly, each profile, page, board, or location is a billable channel, while SocialKit includes its platforms in one flat plan.

SocialKit Solo is €29/month flat (€17.40/month billed annually) and includes 15 social accounts across all 11 platforms, unlimited scheduled posts, analytics, AI on every plan, and API + webhooks.

Postly Pro lists at $16/month billed yearly ($192/year; month-to-month it is $20) — but that is the 5-channel minimum at $3.20 per channel, and channels accumulate faster than you might expect because Pinterest boards and Google Business locations each count separately. Ten channels list at $32/month billed yearly ($40 monthly), with channels 11–100 dropping to $1.60 each (verified June 10, 2026). Postly frames the declining rate as a benefit, and at very high channel counts it can be — but for a typical creator or small business with one brand, the flat plan is simply easier to predict: the price does not change when you add a board.

SocialKit’s trial is the whole product for 7 days: all 11 platforms, unlimited scheduling, AI, API access — €0.00 due today, cancel anytime, with a 7-day money-back guarantee after billing on top.

Postly’s no-risk entry is its free Starter plan: 10 one-time posts for testing, 1GB of storage, and 5,000 monthly AI tokens. That is enough to click around, but you cannot run a real week of publishing on it, and no time-boxed full trial or money-back guarantee is listed on the pricing page (as of June 2026). If you want to genuinely evaluate a scheduler against your actual content calendar, a full-access trial tells you more than ten test posts.

A scheduler has one non-negotiable job: posts go out, on time, as written. Users report on Trustpilot and AppSumo that Postly has stumbled here — scheduled posts lost during a platform migration, hashtags disappearing after scheduling, timezone bugs, and social accounts that expire and need reconnecting. Postly’s G2 reviews are considerably warmer, so experiences clearly vary — but the pattern is worth knowing before you move a month of content.

SocialKit concentrates on those fundamentals: unlimited scheduled posts on every plan, a visual calendar, best-time auto-posting, per-platform customization, first-comment scheduling, and native thread posting on X, Threads, Bluesky, and Mastodon.

Credit where it is due: Postly’s automation story is its real strength. Pro includes unlimited AI tokens under a fair-use policy, API access, and MCP support for AI agents — it positions itself as the execution layer for agent-driven publishing, and nothing else in this price range leans into that as hard.

SocialKit takes a more conventional approach: an AI assistant on every plan (metered credits — 150 on Solo, 500 on Team, 1000 on Enterprise) for captions and ideas, plus API + webhooks on every plan, including Solo — ready for Zapier, Make, and n8n. If you are building agent pipelines, Postly is built for you. If you want AI help while you schedule — without learning an agent platform — SocialKit covers it out of the box.
