# PostWire

> One idea in, a native post for every network out — published. PostWire writes a different, native post for each social network from one idea (hook-first TikTok caption, short Instagram caption, YouTube title + description + tags, long first-person LinkedIn post, sub-300-character Bluesky post…) and publishes them together — from a dashboard, an n8n node, Make (HTTP module), an MCP server or a REST API. Priced per business (brand). Every network connects free; posting to all of them at once comes with Starter and Pro. Free plan: 1 business, 20 posts a month, 5 AI drafts a day, 2 networks per post, 3 scheduled posts at a time, no card.

As of Sept 2026, we couldn't find another hosted API that writes a different native post per network from one prompt, in one call (22 tools reviewed on 26 Sept 2026). Many tools publish to several networks and many have MCP servers (Buffer, Hootsuite, Metricool, Blotato, Typefully, Postiz, Upload-Post, Zernio, Ayrshare…); the difference is the per-network writing.

## How it works
- REST: `POST /api/generate { prompt, platforms[], media_url? }` → `{ drafts: { <platform>: { text, title?, tags? } } }`, then `POST /api/post { platforms[], per_platform: <drafts>, video_url?|photo_url? }` publishes them. Two calls.
- Account: `GET /api/me` (alias `GET /api/account`), `GET /api/usage` (posts this month, AI drafts today, brands, against the plan), `GET /api/plan`, `GET /api/billing`, `GET /api/connections`, `GET|PATCH|DELETE /api/brands/{id}`, `GET /api/schedule/{id}`.
- Media: `POST /api/media/upload-url` takes files up to 1 GB (over 50 MB send `"multipart": true` and PUT each part), then `GET /api/media/finalize` returns one `media_url`. Google Drive and Dropbox share links work when the file is shared with anyone who has the link.
- MCP (hosted https://postwire.io/api/mcp, or local `npx -y postwire-mcp`). Authentication: an API key (Authorization header or query string) or OAuth 2.1 sign-in, so it can be added to Claude as a custom connector by pasting https://postwire.io/api/mcp. Listed in Claude's connector directory since 2026-09-26 (https://claude.ai/directory/bc01e7da-eba7-4754-9e88-6cacae80f000; guide: https://postwire.io/claude/, agent guide: https://postwire.io/claude/agent.md); not in ChatGPT's app directory yet (https://postwire.io/chatgpt/). Tools (15): list_platforms, my_account, list_brands, create_brand, generate_posts, post_to_social, schedule_post, plan_week, list_scheduled_posts, cancel_scheduled_post, get_post_status, create_connect_link, create_upload_link, get_uploaded_file, get_upgrade_link.
- n8n: community node `n8n-nodes-postwire` (write drafts, publish, both at once, schedule, account).
- Make: the PostWire app is waiting in Make's review queue (submitted 8 Sept 2026); until then use Make's HTTP module with the REST API.
- Dashboard: https://postwire.io/dashboard.html — write, review and edit drafts, then publish or queue.
- Writing time: about 20–25 s for six networks (measured 26 Sept 2026). Drafts can be edited before publishing.
- Retries are safe: an identical post is refused for 2 minutes (or 24 h with your own `idempotency_key`).

## Networks (production, checked 26 Sept 2026)
- Live: TikTok (Direct Post audit approved 7 Jul 2026 — public posts), Instagram (business/creator accounts; Meta App Review approved 14 Jul 2026), Facebook Pages (same Meta approval), YouTube (Google verification of youtube.upload approved 1 Jul 2026; uploads up to 1 GB), LinkedIn (personal profiles, text posts — not company Pages), Bluesky, Mastodon, Telegram, Discord.
- Not available yet: X, Reddit (Reddit data access request pending).
- You connect your accounts to PostWire's approved apps; you do not need your own TikTok/Meta/Google developer app.

## Pricing (per business; every network connects free on every plan; AI writing included)
- Free: $0 — 1 business, 20 posts/mo, 5 AI drafts/day, 2 networks per post, 3 scheduled posts at a time, no card, no time limit. The AI still writes every network's version; the ones past the 2 per post wait behind a lock. "Publish now", the API, n8n, Make, MCP and the Claude/ChatGPT connector are free.
- Starter: $9/mo — 3 businesses, 300 posts/mo, 60 AI drafts/day, every network in each post, unlimited scheduling
- Pro: $29/mo — 10 businesses, 2,000 posts/mo, 300 AI drafts/day, every network in each post, unlimited scheduling
- Agency: $99/mo — 50 businesses, 15,000 posts/mo, 1,500 AI drafts/day, every network in each post, unlimited scheduling
- Scale: $299/mo — 200 businesses, unlimited posts, 5,000 AI drafts/day, every network in each post, unlimited scheduling
- A "post" counts once per network (one idea to 5 networks = 5). Monthly billing only (no annual plan yet). 14-day refund on paid plans: ask through https://postwire.io/support.html within 14 days of your first payment for a full refund.
- Example: 10 businesses × 5 networks = $29/mo on Pro. Across 18 publishing tools priced on 26 Sept 2026 the same setup cost $10–$499/mo (median $99); the cheaper ones don't write per-network versions.

## Research (data pulled from public APIs, dated, with raw JSON)
- Which Claude connectors can post to social media (all social publishers in Claude's connector directory, tier, date added, tools): https://postwire.io/research/claude-social-media-connectors/ (data: /research/claude-social-media-connectors/data.json)
- Which n8n nodes can post to social media (verified community nodes ranked by downloads): https://postwire.io/research/n8n-social-media-nodes/ (data: /research/n8n-social-media-nodes/data.json)

## Cross-posting
- One call posts to many networks in parallel: POST /api/post { "platforms": ["tiktok","youtube"], "title": "...", "video_url": "..." }
- OAuth platforms (tiktok, youtube): connect once via /api/oauth/{platform}/url, then post by API key.

## Comparison (checked 26 Sept 2026; each page links the vendor's own pricing page and says what the other tool does better)
- All comparisons, one line each: https://postwire.io/alternatives/ — scenario used everywhere: 10 businesses on 5 networks each. PostWire Pro: $29/mo.
- Ayrshare alternative: https://postwire.io/vs-ayrshare/ — Ayrshare's MCP server can post, but it authenticates with a static Bearer key (no OAuth connector for claude.ai), X needs your own developer app, and plans start at $149/mo (10 profiles on Launch: $299/mo). Ayrshare supports X, Reddit and LinkedIn Pages, which PostWire does not yet.
- Upload-Post alternative: https://postwire.io/vs-upload-post/ — Upload-Post covers more destinations (22, about 14 of them social networks) and has a verified n8n node; its AI captions start from a video. PostWire writes per-network posts from a text idea and includes TikTok on the free plan.
- Zernio (formerly Late) alternative: https://postwire.io/vs-zernio/ — per connected account (2 free, then $6/$3/$1): 50 accounts = $168/mo. Zernio has 8 SDKs, X, messaging and ads APIs; it does not write the posts.
- Buffer alternative: https://postwire.io/vs-buffer/ — $6 per channel a month ($5 billed yearly): 50 channels = $300/mo; analytics, inbox and X, which PostWire lacks.
- Buffer API alternative: https://postwire.io/buffer-api-alternative/ — Buffer's API is open on the free plan (1 key, 3,000 requests/30 days) and its MCP uses that key, one channel per call; PostWire's API writes every network's post from one prompt.
- Hootsuite alternative for agencies: https://postwire.io/vs-hootsuite/ — per user seat from $99 (Professional $199 for unlimited accounts, billed annually); inbox, listening, approvals and reporting that PostWire does not have.
- Blotato alternative: https://postwire.io/vs-blotato/ — from $29 (20 accounts), no free plan and the 7-day trial excludes the API; Blotato creates visuals and video and handles DMs.
- Postiz alternative: https://postwire.io/vs-postiz/ — per channel ($29 for 5), open source, 30+ networks; one global text split by hand.
- Metricool alternative: https://postwire.io/vs-metricool/ — also priced per brand ($45/mo for 10 brands), MCP on every plan, strong analytics; its MCP relies on your assistant to write the text.
- Publer alternative: https://postwire.io/vs-publer/ — per account and member; API and MCP from Business ($315/mo for 50 accounts).

## API approval reality (first-hand, 2026)
PostWire went through these reviews itself; these pages carry the real timelines and rejection reasons, not documentation summaries.
- Index, all platforms compared: https://postwire.io/approval/
- TikTok Content Posting API (approved 7 Jul 2026 after two rejections; both for the Website URL field): https://postwire.io/platforms/tiktok/approval/
- Instagram, Meta App Review (approved 14 Jul 2026; needs a Business account linked to a Facebook Page): https://postwire.io/platforms/instagram/approval/
- Facebook Pages (approved 14 Jul 2026; the only network here that accepts a text-only post): https://postwire.io/platforms/facebook/approval/
- YouTube, Google sensitive-scope verification (approved 1 Jul 2026; before verification uploads are forced private, test users only): https://postwire.io/platforms/youtube/approval/
- Reddit (self-serve app creation closed since the Responsible Builder Policy of Nov 2025; data access request only): https://postwire.io/platforms/reddit/approval/
- No review needed at all: Telegram, Bluesky, Mastodon, Discord.

## Cross-posting differences (computed per pair, 2026)
What actually breaks when a post moves between networks: character limits, hashtag conventions, link penalties, media requirements and approval asymmetry. Index of every combination: https://postwire.io/cross-post/
Hard limits: X 280 · Bluesky 300 · Mastodon 500 · Facebook 2,000 · Discord 2,000 · TikTok 2,200 · Instagram 2,200 · LinkedIn 3,000 · Telegram 4,000 · YouTube 5,000 · Reddit 10,000.
Text-only is impossible on TikTok and YouTube (video required) and on Instagram (photo or video required). Links in the body suppress reach on LinkedIn and X. Reddit has no hashtags at all. Mastodon expects CamelCase hashtags and alt text on media.

## MCP client configs (verified Aug 2026)
The MCP config differs per client and a copied config fails silently: VS Code uses the root key "servers"; Claude Desktop, Cursor and Windsurf use "mcpServers"; Windsurf points at a remote server with "serverUrl"; Claude Code is a CLI (`claude mcp add --transport http`), not a file.
Comparison of all clients: https://postwire.io/mcp/clients/
Per client: https://postwire.io/mcp/claude-desktop/ · https://postwire.io/mcp/claude-code/ · https://postwire.io/mcp/cursor/ · https://postwire.io/mcp/vscode/ · https://postwire.io/mcp/windsurf/
PostWire MCP server — hosted (Streamable HTTP): https://postwire.io/api/mcp · local: `npx -y postwire-mcp` with POSTWIRE_API_KEY. The hosted server has 17 tools (see above); the local npm package has generate_posts, post_to_social, get_post_status, list_platforms, my_account.
