$3.99/mo vs $29/mo: 600 req/min, no channel caps
Postiz is one of the best open-source scheduling tools around, but its API caps out around 30 requests an hour with channel and post limits on every tier. Bulkit was built API-first and kept the calendar, so your team still gets drag-and-drop scheduling while your code gets 600 requests a minute.
It comes down to who is doing the posting, and the calendar is not the deciding factor: both products have one, so scheduling posts by dragging them around a week view is available either way. What differs is what happens when your application, a pipeline or an agent does the publishing instead of a person. Postiz Cloud's public API allows roughly 30 requests an hour, caps connected social accounts by tier (5 on the $29 Standard plan, 100 on the $99 Ultimate), and treats the API as one feature inside a scheduling app. Bulkit inverts that: every supported platform is reachable from one endpoint at 600 requests per minute, on a single $3.99/month plan with 500 actions included and unlimited connected accounts, then a cent per action. Same job, different centre of gravity, and you keep the calendar either way.

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 |
Bulkit is ~2.6× cheaper at this volume
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, with unlimited accounts and 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.
The hourly API ceiling is the real cap
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.

Three things change on day one. Your throughput ceiling moves from an hourly number to a per-minute one, so a backfill or a busy agent stops being a scheduling problem. Your account limit disappears, so onboarding your hundredth customer costs the same as your first. And the API stops being api-accessible-on-paid-tiers and becomes simply the product: there is no plan on which it is switched off, because there is only one plan. What you give up is real and worth naming: the bundled AI content tools, the open-source codebase, and the self-hosting option. The calendar is not on that list. Bulkit has one too.
This is the real difference between the two products, and it is structural rather than a feature either side could simply add. Postiz is an application that grew an API, so the public API inherits the shape of the app around it, which is why throughput is measured per hour and capabilities land in the UI first. Bulkit was built the other way round. The REST endpoints are designed, versioned and documented first, and every other surface (the SDK, CLI, webhooks, n8n node, MCP server and the dashboard's own drag-and-drop calendar) is a thin shell over exactly those endpoints. Nothing in the UI is unreachable from a request, and nothing in the API waits on a UI release. That is what makes scheduling posts from code the primary path here rather than the escape hatch, without costing your team the calendar they actually wanted.
Start with the Bulkit API quickstart, where an API key and one request is the whole first step.
Being upfront about when Postiz wins is what makes the rest of this page worth trusting.
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 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.
Because the licence is the cheap part. Postiz is genuinely free to self-host and that is a real hosting option worth taking seriously, especially if you want to own your data and read the source. What self-hosting does not remove is the platform work: you still create your own developer apps on Meta, TikTok, YouTube, LinkedIn and X, sit through each platform's app review, and keep up when their APIs change or tokens break. That's weeks of work, then ongoing maintenance, plus running Postgres and Redis and their upgrades. Bulkit is the opposite trade: $3.99/month, no infrastructure, no app review because our platform apps are already approved, and the API is accessible on the only plan there is. If your team enjoys running infrastructure and has time for platform reviews, self-hosting Postiz is a legitimately good answer. If your scarce resource is engineering weeks rather than dollars, it is not.
Yes. Bulkit's dashboard includes a full drag-and-drop scheduling calendar, so this isn't a trade-off you have to make. The difference is which one is the centre of gravity. On Postiz the calendar is the product and the public API is a feature attached to it, which is why that API is capped at roughly 30 requests an hour. On Bulkit the API is the product and the calendar is a first-class surface on top of it, so your team can drag posts around a week view while your code publishes at 600 requests a minute against the same queue.
Postiz, on breadth: it lists 30+ channels including Discord, Mastodon, Telegram and blog targets. Bulkit covers 12 (X, Instagram, TikTok, YouTube, LinkedIn, Facebook, Threads, Pinterest, Bluesky, Vimeo, Reddit and Google Business) where most audience attention lives, with infrastructure-grade reliability on every supported platform. 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.
