SocialKit vs PostFast

Both tools advertise 11 platforms, and ten of them overlap: Instagram, TikTok, YouTube, Facebook, LinkedIn, X, Threads, Bluesky, Pinterest, and Google Business. The eleventh slot is where they diverge — SocialKit includes Mastodon, PostFast includes Telegram.

Which gap matters depends entirely on your audience. If you publish to the fediverse, SocialKit is the only one of the two that can post to Mastodon natively. If your community lives in Telegram channels, PostFast has you covered there and SocialKit does not — that is an honest trade. One small caveat: PostFast’s homepage lists Google Business Profile, but some of its own platform lists omit it, so verify it works for your use case before relying on it.

PostFast is built around speed — “Schedule a Week of Content in Minutes” — and it has some genuinely nice publishing touches, like automatic video transcoding to each platform’s spec and CSV bulk upload for hundreds of posts at once.

The constraint is volume. PostFast caps scheduled posts per tier: 150 on Starter, 1,500 on Creator, 3,000 on Growth, with unlimited scheduling only on Pro and Enterprise (as of June 2026). Drafts are capped too — 50 on Starter, 600 on Creator — and so is how far ahead you can schedule: 90 days on Starter, 180 on Creator, 240 on Growth. SocialKit puts no cap on scheduled posts on any plan, alongside best-time auto-posting, first-comment scheduling, per-platform customization, and native thread posting on X, Threads, Bluesky, and Mastodon. If you batch heavily or recycle content, caps are exactly the kind of ceiling you hit at the worst moment.

Let’s be straight: PostFast’s Starter plan, listed at €10/month billed yearly (€12 month-to-month), is cheaper than anything SocialKit sells. If you have 4 or fewer accounts, post lightly, and never need Mastodon, Starter is a perfectly rational pick — that is the honest trade-off.

The picture changes as soon as you compare like for like. SocialKit Solo is €29/month flat (€17.40/month billed annually) with 15 social accounts and unlimited scheduled posts. PostFast’s closest tier is Creator, listed at €24/month billed yearly or €29 month-to-month — the exact same monthly sticker as Solo — with 12 accounts and a 1,500-post cap (verified June 10, 2026). So at the comparable level, SocialKit is the same price or cheaper and includes more accounts, no post caps, and Mastodon.

PostFast structures teams around workspaces — 1 on Starter, 4 on Creator, 10 on Growth, 30 on Pro — with user seats scaling from 1 up to 15 across the same ladder, and approval workflows with access levels listed on paid plans. For agencies juggling many brands, the workspace model is a sensible design, and the 120-account Pro tier is clearly aimed at them.

SocialKit’s Team plan is a flat €49/month (€29.40/month billed annually) with 30 social accounts, 2 seats (extra teammates €2 each, extra accounts €4 each), an approval flow, and comments on posts. For a small team, the practical difference is what sits behind the entry tiers: on PostFast, a solo Starter user gets exactly 1 seat and 150 scheduled posts; on SocialKit, even Solo gets unlimited scheduling.

Both products take automation seriously. PostFast offers API access on every plan and showcases integrations with ChatGPT, Claude, n8n, Zapier, and Make. SocialKit ships API access and webhooks on every plan, including Solo. That last word matters: PostFast’s own comparison pages note that webhooks are not offered (as of June 2026), so event-driven automations — “when a post publishes, do X” — are a SocialKit-only capability between these two. SocialKit also includes a native AI assistant on every plan, metered with credits (150 on Solo, 500 on Team, 1000 on Enterprise) — AI on every plan, not unlimited.

On support, PostFast reserves priority support for its Pro and Enterprise tiers, listed at €82.50 and €199/month billed yearly. SocialKit offers email support on every plan with priority support on Enterprise — and adds a 7-day money-back guarantee that PostFast’s pricing page does not list.
