$3.99/mo vs $29/mo — 600 req/min, no channel caps
Postiz is one of the best open-source social schedulers around — calendar, AI content tools, 30+ channels. But if you're a developer who needs to publish programmatically, you hit its walls fast: ~30 API requests an hour, channel caps per plan, posts-per-month limits. Bulkit was built the other way around — API first, everything else second.

Bulkit is one flat plan that scales by usage. Postiz Cloud tiers by how many channels you connect and gates the public API behind paid plans — so the bill grows with your account count, and your automation shares an hourly API ceiling on every tier.
| Bulkit | Postiz | |
|---|---|---|
| Entry plan | $3.99/mo | $29/mo (Standard) |
| Included volume | 500 posts & comments/mo | 400 posts/mo (Standard) |
| Overage | $0.01 per action — no hard cap | Upgrade a tier |
| Connected channels | Unlimited on every plan | 5 (Standard) → 100 (Ultimate $99/mo) |
| Public API | Every plan — it is the plan | From Standard ($29/mo) |
| API rate limit | 600 req/min, every plan | ~30 req/hr (create-post ~90–100/hr) |
| Higher tiers | None — the same plan scales | Team $39 / Pro $49 / Ultimate $99 |
| Free option | No free plan — no card to start | Self-host (free, your infra); no free cloud plan |
Posting 2,000 times a month across 20 connected accounts
On Bulkit that's the flat $3.99 plus 1,500 metered actions at $0.01 — unlimited accounts, no throughput ceiling. On Postiz Cloud, 20 channels puts you on the Pro tier ($49/mo, 30 channels), and your automation still shares that ~30 req/hr public-API ceiling no matter which tier you're on.
None of this is a knock on Postiz — a scheduler doesn't need infrastructure-grade rate limits. But if your use case is 'my app or agent posts on behalf of users' or 'my pipeline publishes hundreds of items a day', a two-digit hourly rate limit is a dealbreaker, not a detail. Bulkit is built to be the API: 600 requests/minute on every plan and no channel caps, so throughput scales with your product instead of your invoice.

Postiz has a real, executable MCP server — your agent can list integrations, schedule and publish posts, even generate images and videos. This isn't 'we act, they only read docs.' The honest difference is the plumbing underneath: Postiz's MCP rides the same ~30 req/hr public API and the same channel-capped tiers, and is write-only on posts (no comment or DM tools). Bulkit's MCP runs on infrastructure-grade throughput with unlimited connected accounts and covers comments too — so an agent posting at volume doesn't hit an hourly wall.

Sign up and grab a key — no credit card, no sales call. The API is the plan, so there's no tier to pick before you can call it.
Drop the per-integration post arrays. One Bulkit call with "all" targets fans a post out across every account you've connected — no per-hour batching gymnastics.
Run each account through Bulkit's OAuth flow once (our platform apps are already approved — no Meta or TikTok review), then swap the Postiz node for the Bulkit node in your n8n workflows.

}For API-driven workloads, usually: $3.99/mo + $0.01/action versus Postiz Cloud's $29–$99/mo tiers. For a human team that wants a scheduling UI with built-in AI tools, Postiz's tiers may map better — and self-hosting Postiz is free if you run the infrastructure. Compare against your real volume and account count.
Postiz's docs list roughly 30 requests per hour on the public API overall (the create-post endpoint allows about 90/hr self-hosted, 100/hr on cloud), and they recommend batching several posts into one request. Bulkit allows 600 requests/minute on every plan, built for programmatic throughput rather than an hourly app-side cap.
True — and for a free scheduler UI for yourself, self-hosted Postiz is a great deal. But self-hosting doesn't remove the hard part: you still have to create developer apps on Meta, TikTok, YouTube, LinkedIn and X, pass each platform's app review, and keep up when their APIs change or your tokens break. That cost is measured in weeks, not dollars — plus running the stack (Postgres, Redis) and its upgrades. Bulkit's $3.99/mo exists so you never touch a platform app review: our apps are already approved and our team absorbs the API churn.
Bulkit has a dashboard, but a calendar-first scheduling UI is Postiz's home turf, not ours. Bulkit's scheduling lives in the API — you POST a time and target, and we queue, retry and report on it. If your team wants to drag posts around a visual calendar, Postiz does that better.
No — Bulkit is the publishing layer, not a content studio. Postiz bundles AI images, video and a writing copilot; Bulkit deliberately doesn't. Pair Bulkit with any AI stack (or an MCP agent) and we'll handle distribution across your networks.
Postiz, on breadth: it lists 30+ channels including Discord, Mastodon, Reddit, Telegram and blog targets. Bulkit covers 9 major networks — X, Instagram, TikTok, YouTube, LinkedIn, Facebook, Threads, Pinterest and Bluesky — where most audience attention lives, with infrastructure-grade reliability on each. If you need Discord, Mastodon or blog publishing today, Postiz has the wider list.
Yes. Postiz ships a real executable MCP server that schedules, publishes and generates media — so the difference isn't 'they only draft, we act.' It's what's underneath: Postiz's MCP rides the same ~30 req/hr public API and channel-capped plans, while Bulkit's runs on per-minute throughput with unlimited accounts and also exposes comments. For an agent posting at volume, that ceiling is the deciding factor. See /mcp for Bulkit's agent story.
