A social media API for n8n that writes each network's post for you
Most n8n posting workflows chain an LLM node, a prompt per network and a posting node per network. PostWire's node replaces that chain: one step turns an idea into a native post for each network and publishes it. Here is how it compares with the other nodes, including where they're ahead.
Short answer. If you need a node verified by n8n (required on n8n Cloud) or the biggest template library, Blotato, Upload-Post, Buffer, Postiz and Zernio have one and PostWire doesn't yet. If you self-host n8n and want the per-network writing inside the node, priced per business, PostWire's community node does it — and on Cloud its REST API works through the HTTP Request node.

n8n posting nodes, side by side
Verification status and templates as shown on n8n.io and each vendor's site on Sept 26, 2026.
| Tool | n8n node | Verified by n8n | Writes a post per network | 10 businesses × 5 networks |
|---|---|---|---|---|
| PostWire | Community node n8n-nodes-postwire 0.3.0 | Not yet — requested | Yes, from one idea, inside the node | $29 |
| Blotato | Yes, ~80 templates on n8n.io | Yes | On request in its chat | $499 |
| Upload-Post | Yes, ~12 templates on n8n.io | Yes | From a video, 4 networks | $50 |
| Buffer | Yes, ~13 templates on n8n.io | Yes | No (one channel per call) | $300 |
| Postiz | Yes, ~13 templates on n8n.io | Yes | No | $99 |
| Zernio | Yes, a few templates | Yes | No | $168 |
| Ayrshare | No node (HTTP Request or MCP Client) | — | No | $299 |
“Writes a post per network” means the tool itself produces a different native text for each network from one input. Everyone above can publish text you write.
Where the others are ahead of PostWire
- Verified nodes: Blotato, Upload-Post, Buffer, Postiz and Zernio are verified by n8n, so they install on n8n Cloud. PostWire's isn't yet.
- Template libraries: Blotato has about 80 on n8n.io; Upload-Post, Buffer and Postiz about a dozen each. PostWire has none for its node yet (two older ones use the HTTP Request node).
- More networks, including X and Reddit. Not on PostWire yet.
Why a node that writes matters in n8n
In an AI agent chat, the model can write five versions for you. In n8n there is no model at the wheel unless you add one: a typical workflow is trigger → LLM node → a prompt per network → a posting node per network, and every prompt is yours to maintain.
PostWire's node does the writing on the server: the TikTok caption leads with a hook, YouTube gets a searchable title, description and tags, LinkedIn a longer first-person post, Bluesky stays under 300 characters. It also refuses a post that a network would reject — TikTok and YouTube need a video, Instagram a photo or video — in the editor, before the workflow runs.
Using PostWire in n8n today
Self-hosted n8n: Settings → Community nodes → install n8n-nodes-postwire, add a PostWire API key, and pick the operation that writes and publishes. Step-by-step setup is in the n8n guide.
n8n Cloud: Cloud only installs verified nodes, and ours is still waiting on n8n's verification. Until then, use two HTTP Request nodes against the REST API — the same thing the node does:
POST https://postwire.io/api/generate
{ "prompt": "{{ $json.idea }}", "platforms": ["tiktok","instagram","linkedin"] }
POST https://postwire.io/api/post
{ "platforms": ["tiktok","instagram","linkedin"],
"per_platform": {{ $json.drafts }}, "video_url": "{{ $json.video }}" }Both calls take the header Authorization: Bearer pw_live_…. More in the n8n guide.
One idea in, one post per network out
This is what the writing step returns before anything is published — one native post per network.
The idea: We're a family bakery. This Saturday we launch sourdough cinnamon rolls, and the first 50 are free with any coffee.
Free sourdough cinnamon rolls. This Saturday. First 50. ☕🍥 Come grab yours with any coffee order! #sourdoughcinnamonrolls #familybakery #cinnamonrolls #bakery #freefood
We've been a family bakery for years. This Saturday, we're doing something we've never done before. We're launching sourdough cinnamon rolls — and the first 50 are free with any coffee. This wasn't a quick decision. We tested the recipe for weeks. Got the fermentation time wrong. Twice. Overproofed a whole batch on a Tuesday. And then one morning, we pulled a tray out of the oven and just… knew. The slow ferment gives the dough a subtle tang that cuts through the sweetness of the cinnamon filling. It's the kind of thing that's hard to describe but impossible to miss when you taste it. We're a small, family-run operation. We don't have a marketing budget or a PR team. What we have is an oven, a sourdough starter that's older than our youngest kid, and a neighborhood we genuinely love feeding. Launching something new is always a little nerve-wracking — you never quite know if the thing you've poured your energy into will land the way you hoped. But that's also what makes it exciting. If you're local, come find us this Saturday. First 50 sourdough cinnamon rolls are on us with any coffee order. Come early — we don't expect them to last long. And if you're not nearby, I'm curious — what's the best thing you've ever eaten from a small, independent bakery? Drop it in the comments. 👇 #FamilyBusiness #Sourdough #SmallBusiness

Questions people ask
Is there a PostWire node for n8n?
Yes: the community node n8n-nodes-postwire (version 0.3.0). It writes a native post per network, publishes, schedules and reads your account. It is not verified by n8n yet, so it installs on self-hosted n8n; on n8n Cloud, use the HTTP Request node with the REST API.
Which social media nodes are verified by n8n?
Among the tools on this page, Blotato, Upload-Post, Buffer, Postiz and Zernio showed a verified node on Sept 26, 2026; Ayrshare and Metricool had none. PostWire's verification is pending.
Do I still need an LLM node to write the posts?
Not with PostWire: the node writes a different native post for each network from one idea. With the other nodes you write the text yourself or add an LLM node and a prompt per network.
Which networks can the PostWire node post to?
TikTok, Instagram, Facebook Pages, YouTube, LinkedIn personal profiles, Bluesky, Mastodon, Telegram and Discord. X and Reddit are not available yet.
What does it cost?
PostWire is priced per business with every network included: free for 1 business (30 posts a month, no card), $9 for 3, $29 for 10, $99 for 50. Paid plans have a 14-day refund.
