$4.99/mo vs $29/mo: 600 req/min, no channel caps
Postiz is one of the best open-source scheduling tools around, but its API allows about 100 create-post requests an hour and every plan caps how many channels you can connect. 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 about 100 create-post requests an hour (one request can batch several posts), 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 $4.99/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 (posts are unlimited on every plan), so the bill grows with your account count, and your automation shares the same hourly create-post limit on every tier.
| Bulkit | Postiz | |
|---|---|---|
| Entry plan | $4.99/mo | $29/mo (Standard) |
| Included volume | 500 posts & comments/mo | Unlimited posts on every plan |
| Going over | $0.01 per action, no hard cap | Upgrade a tier for more channels |
| 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 | ~100 create-post requests/hr, same on every plan |
| Higher tiers | None, the same plan scales | Team $39 / Pro $49 / Ultimate $99 |
| Free option | No free plan; 14-day free trial, then $4.99/mo | Self-host (free, your infra); no free cloud plan |
Bulkit is ~2.5× cheaper at this volume
Posting 2,000 times a month across 20 connected accounts
On Bulkit that's the flat $4.99 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 the same ~100 create-post requests an hour 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', an hourly limit on creating posts is something you engineer around, batching requests and queueing retries, rather than 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 hourly create-post limit and the same channel-capped tiers, and has no tools to read or reply to comments. 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.

Postiz has a real API, so you can script the move instead of retyping posts. Bulkit has no CSV or bulk import; the script below is the import.
Bulkit posts through your own developer app on each network: add each app's keys under Platform apps, then connect every account once in the Bulkit app. If you self-host Postiz you already have these apps, so reuse their keys and add Bulkit's redirect URI. Instagram, Facebook, Threads and TikTok need app review before they post beyond test accounts.
Read your queue with Postiz's List Posts endpoint. Each Postiz integration becomes a channel id from GET /channels; each post group becomes one POST /posts with intent "schedule" and every channel in one request, each with its own blocks (several blocks make a thread). Re-upload media with POST /media, and point agents at Bulkit's MCP server.
Run the migration with a bk_test_ key first: test keys run every check and return the same errors as live ones but never publish. Postiz keeps publishing the real queue meanwhile, so nothing goes out twice.
Delete the migrated posts in Postiz, rerun with a live key, and move your Postiz webhooks to Bulkit's post.published, post.failed and channel.needs_reconnect events. Then disconnect the channels in Postiz.
For API-driven workloads, usually: $4.99/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 limit the create-post endpoint to 90 requests per hour (100 on Postiz Cloud), the same on every plan; self-hosters can change it. One request can carry several posts, and the docs recommend batching. 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 keep up when each network's API changes or tokens break, and you run Postgres and Redis and their upgrades. That's ongoing maintenance on top of the integration work. Bulkit is the opposite trade: $4.99/month, no infrastructure, and the API is accessible on the only plan there is. If your team enjoys running infrastructure, 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's create-post endpoint is limited per 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 hourly create-post limit 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.
