# Brief 8 — Cross-post tool matrix & X compatibility
**Audience:** weebo / systemctl / usectl  
**Angle:** (a) tool matrix + X compatibility only (video worth-it is out of scope)  
**Context:** one founder, one agent (Claude) with APIs/MCP; self-hosting on usectl is easy; X is home channel; story = text + occasional cover image; no video yet.  
**Target networks:** X, YouTube, TikTok, LinkedIn, Threads, Bluesky, Instagram, Reddit, Mastodon  
**Scope:** open web, GitHub, tools’ own docs/pricing; 2025–26 only  
**Date:** 2026-09-05 (Asia/Tbilisi)
---
## Executive summary
For an **agent-driven, X-home, nine-network** build-in-public pipeline, **Postiz (self-hosted on usectl)** is the only researched tool that natively covers **all nine** targets (X + YT + TikTok + LI + Threads + Bluesky + IG + Reddit + Mastodon) with a public API, MCP/CLI, and AGPL self-host. Cloud Postiz starts at **$29/mo** (5 channels).
**Runner-up for API-native agents:** **Zernio** (formerly Late / getlate.dev) — usage-based API + MCP, first **2 accounts free**, X costs **passed through** at official rates. Covers 8/9 targets (**no Mastodon**).
**Cheap cloud + X included + MCP:** **Buffer** Essentials (~**$6/channel/mo**). Covers 8/9 (**no Reddit**). Media via public URL, not direct upload.
**Avoid for this brief’s X requirement:** **Hypefury** (official FAQ: no longer supports X). **Typefully** is excellent for X-writing + MCP but lacks YT/TikTok/IG/Reddit.
**X pay-per-use reality (official):** Post Create **$0.015**; Post Create with URL **$0.200**; Post Read **$0.005**. Self-host tools that BYO X apps (Mixpost) bill those costs to **you**. Hosted partners either absorb, surcharge (Metricool **$10/mo per X account**), pass through (Zernio), or force BYO keys (Ayrshare since **2026-03-31**).

- **X:** Dedicated guide for **Pay as you go** X API; paste API Key/Secret into Mixpost ([X integration docs](https://docs.mixpost.app/services/social/x/)). **You pay X credits directly.**
### 3. Buffer
- **Platforms (API):** Instagram, Threads, LinkedIn, X, Facebook, TikTok, GBP, Mastodon, YouTube, Pinterest, Bluesky — **11** ([support article](https://support.buffer.com/en-us/articles/what-is-buffers-api-GtIYIQilz5)). **No Reddit.**

- **Hosting:** Cloud.
- **Price:** Free: 3 channels, 10 scheduled posts/ch, 3k API req/30d. Essentials from **$6/channel/mo** (volume discounts). Team from **$12/channel** ([pricing](https://buffer.com/pricing)).
- **Media:** Images/videos via **public URL** (no direct multipart upload via API).
- **Analytics:** Strong in UI; API analytics **experimental / not recommended for production** ([support](https://support.buffer.com/en-us/articles/what-is-buffers-api-GtIYIQilz5)).
- **Catch:** Per-channel math; Reddit gap; media hosting requirement.
- **X:** Included on Free and paid; Buffer states official partner status with X ([developers page](https://buffer.com/made-for/developers)).
### 4. Typefully
- **Platforms:** X, LinkedIn, Threads, Bluesky, Mastodon ([scheduling page](https://typefully.com/social-media-scheduling); [API help](https://support.typefully.com/en/articles/8718287-typefully-api)). No YT/TikTok/Reddit; IG “soon.”
- **Agent:** REST **v2** (Dec 2025), webhooks, **MCP** (`mcp.typefully.com`), Agent Skills ([ai-agents](https://typefully.com/ai-agents), [llms.txt](https://typefully.com/llms.txt)).
- **Hosting:** Cloud.
- **Price:** Official pricing page is JS-heavy (numbers not reliably scraped 2026-09-05). Third-party reviews cite Free + Creator ~**$12.50/mo annual / ~$15 monthly** — **confirm on typefully.com/pricing** ([example review](https://agent-finder.co/reviews/typefully)).
- **Catch:** Wrong tool if YouTube/TikTok/IG/Reddit are hard requirements.
- **X:** First-class; API warns to follow X automation rules.
### 5. Hypefury
- **Platforms (pricing page):** Bluesky, Threads, LinkedIn, Instagram, TikTok ([features-pricing](https://hypefury.com/features-pricing/)).
- **Agent:** No public REST/MCP documented.
- **Price:** Flexible **$6/mo** per channel; Full plan referenced ~**$19/mo** in secondary sources.
- **X:** Official FAQ: **“Nope! Hypefury no longer supports 𝕏”** ([same page](https://hypefury.com/features-pricing/)).
- **Verdict for this brief:** **Disqualified** on X + agent.
### 6. Publer
- **Platforms:** Facebook, Instagram, X, LinkedIn, Pinterest, YouTube, TikTok, GBP, WordPress, Telegram, Mastodon, Threads, Bluesky ([API networks](https://publer.com/docs/posting/create-posts/networks.md)). **No Reddit.**
- **Agent:** REST API on **Business & Enterprise** ([API launch post](https://publer.com/blog/publer-api-for-marketers-and-developers/)).
- **Price:** Professional starts **$5/mo**/account; Business **$10/mo**/account ([help center](https://publer.com/help/en/article/professional-vs-business-vs-enterprise-plans-1sge3f7/)). Free: up to 3 accounts, **no X**.
- **Catch:** Need Business for API; X paid-only.
- **X:** Supported on paid; blocked on Free (API cost cited by Publer reviews).
### 7. Late → Zernio (getlate.dev)
- **Rebrand:** Late is now **Zernio**; getlate.dev redirects; same API keys ([rebrand](https://zernio.com/rebrand)).
- **Platforms:** twitter, instagram, facebook, linkedin, tiktok, youtube, pinterest, reddit, bluesky, threads, googlebusiness, telegram, snapchat, whatsapp, discord, slack — **no Mastodon** ([docs](https://docs.zernio.com/), [platforms](https://docs.zernio.com/platforms)).
- **Agent:** REST `/api/v1`, SDKs, CLI, webhooks, **MCP** (marketing claims 280+ tools), n8n node ([zernio.com/social-media-api](https://zernio.com/social-media-api)).
- **Price:** Accounts 1–2 **free**; 3–10 **$6** each; 11–100 **$3**; 101+ **$1** ([pricing](https://zernio.com/pricing)). Example: 10 accounts = **$48/mo**.
- **X pass-through (zero markup):** Reads **$0.005**; Posts **$0.015**; Posts with URL **$0.200** — matches X’s own card ([Zernio pricing](https://zernio.com/pricing), [X pricing.md](https://docs.x.com/x-api/getting-started/pricing.md)).
- **Catch:** Mastodon gap; URL-heavy BIP posts get expensive on X via pass-through; cloud only.
### 8. Ayrshare
- **Platforms:** 13 networks including Bluesky, Facebook, GBP, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, Telegram, Threads, TikTok, X, YouTube ([API overview](https://www.ayrshare.com/docs/apis/overview)). **No Mastodon** in that list.
- **Agent:** REST + MCP (docs reference MCP with same BYO X headers).
- **Price:** Premium **$149**/mo (1 profile, many networks); Launch **$299**; Business from **$599** ([pricing](https://www.ayrshare.com/pricing/)). One profile can attach many networks — good for multi-network **one brand**, still steep vs Postiz/Buffer.
- **X:** From **2026-03-31**, **BYO OAuth1 API Key + Secret** on every X request; X credits purchased in X Developer Console; Ayrshare does not markup X usage ([BYO keys](https://ayrshare-docs.mintlify.dev/docs/dashboard/connect-social-accounts/x-twitter-byo-keys), [connect X](https://www.ayrshare.com/docs/dashboard/connect-social-accounts/x-twitter)).
### 9. Metricool
- **Platforms:** Broad scheduler (IG, TikTok, YT, LI, etc.); Free plan **no LinkedIn, no X** ([plans help](https://help.metricool.com/plans-add-ons-and-api-access-explained-xux1u.md)).
- **Agent:** **MCP on any plan**; REST API only **Advanced/Custom** ([same](https://help.metricool.com/plans-add-ons-and-api-access-explained-xux1u.md)).
- **Price:** Starter from ~**$20–25**/mo (annual/monthly); Advanced from ~**$53**/mo ([metricool.com/metricool-premium](https://metricool.com/metricool-premium/)).
- **X:** Add-on **€10/$10 per X account per month** (or $120/yr) on Starter+ ([X access](https://help.metricool.com/x-twitter-access-in-metricool-2bt66.md), [add-on guide](https://help.metricool.com/your-guide-to-the-x-twitter-add-on-wt5wy)).
- **Catch:** Agent publish via API needs Advanced; X surcharge stacks; Reddit/Mastodon support **not verified** in this pass.
### 10. SocialBee
- **Platforms (direct):** Facebook, Instagram, Threads, LinkedIn, X, Pinterest, TikTok, YouTube, GBP, Bluesky ([pricing](https://socialbee.com/pricing/), [home](https://socialbee.com/)).
- **Agent:** Zapier / Make / Pabbly; **no public REST API** (long-term roadmap per tertiary catalog). Undocumented MCP endpoint claimed by APIs.io — treat as **unverified for production agents**.
- **Price:** Bootstrap **$29**/mo (5 accounts), Accelerate **$49** (10), Pro **$99** (25) ([pricing](https://socialbee.com/pricing/)).
- **X:** Supported on listed plans.
- **Catch:** Weak first-class agent API; missing Reddit/Mastodon direct posting.
### 11. n8n / Make (recipes)
- **Role:** Orchestration, not network coverage. Typical pattern: RSS/Notion/ship webhook → LLM rewrite → **Postiz / Buffer / Zernio** createPost.
- **n8n:** Self-host on usectl; Postiz has official/custom node ([Postiz docs n8n video](https://docs.postiz.com/public-api/introduction)); Buffer lists n8n on pricing integrations.
- **Make:** Visual scenarios; Buffer + Zernio webhook/HTTP modules.
- **Price:** n8n self-host ≈ infra; Make cloud per-operation; **plus** publisher subscription.
- **Catch:** Doubling tools without a publisher that already has MCP often adds complexity for a single founder+agent.

## X compatibility section
### Official X API rates (pay-per-use)
Source: [docs.x.com pricing.md](https://docs.x.com/x-api/getting-started/pricing.md) (fetched 2026-09-05):
| Operation | Unit cost |
|-----------|-----------|
| Posts: Read | **$0.005** / resource |
| User: Read | **$0.010** / resource |
| **Post: Create** | **$0.015** / request |
| **Post: Create (with URL)** | **$0.200** / request |
| Post: Create (summoned) | $0.010 / request |
Credits prepaid in Developer Console; pay-per-use Post reads capped at **3M/month**. Prices subject to change — console is source of truth ([developer.x.com/#pricing](https://developer.x.com/#pricing)).
**Implication for BIP:** almost every ship post has a link → **$0.20 per X post** if **you** hold the X app keys. 30 linked posts/mo ≈ **$6** just for X create (plus reads/analytics).
### Who still posts to X — and at what added cost
| Tool | Still posts to X? | Who pays X API? | Added cost vs base plan |
|------|-------------------|-----------------|-------------------------|
| **Postiz** | Yes | Unclear on cloud (likely absorbed — **unconfirmed**); self-host = **you** if you BYO X app | Cloud: $0 explicit; self-host: X credits |
| **Mixpost** | Yes | **You** (pay-as-you-go) | X credits ($0.015 / $0.20 per post) |
| **Buffer** | Yes (incl. Free) | Buffer (partner) | Bundled in channel fee |
| **Typefully** | Yes | Typefully (assumed bundled) | Bundled |
| **Publer** | Yes (paid only) | Publer | Bundled; Free excludes X |
| **Zernio** | Yes | **You via pass-through** | Exact X rates, $0 markup |
| **Ayrshare** | Yes | **You** (BYO keys + credits) | X credits; plan unchanged |
| **Metricool** | Yes | Metricool + surcharge | **+$10/mo per X account** |
| **SocialBee** | Yes | SocialBee (assumed) | Bundled |
| **Hypefury** | **No** | N/A | Lost X entirely |
### Who lost X entirely
- **Hypefury** — primary source FAQ ([hypefury.com/features-pricing](https://hypefury.com/features-pricing/)).
- **Later** — secondary sources say X sunset Aug 2025 ([Blotato schedulers roundup](https://www.blotato.com/blog/best-x-twitter-schedulers)); not in must-cover list; **not re-verified** against Later’s own docs this pass.
---
## Ranked shortlist for agent-run accounts (this brief)
1. **Postiz self-hosted on usectl** — only full 9-network matrix + API/MCP/CLI; aligns with “self-hosting is easy.”  
2. **Zernio** — best pure API/MCP DX; free tier; accept Mastodon via native client or second hop; budget X link costs.  
3. **Buffer Essentials** — lowest-friction cloud MCP + X included; add Reddit via separate API or skip.  
**Honorable:** Mixpost Pro if you want one-time license and accept BYO apps + X credits. **Typefully** if X+LI+Threads+Bluesky+Mastodon is enough and writing UX matters. **Skip** Hypefury (no X), SocialBee (weak API), Ayrshare ($149 floor) for a single founder brand.

## Missing / gaps
1. **Typefully exact list prices** — pricing page did not yield stable dollar amounts via fetch/curl; used third-party figures — **verify in UI**.  
2. **Postiz cloud vs X pass-through** — no explicit “we absorb X API” statement on postiz.com FAQ; self-host X cost model depends on whether you register your own X app (docs emphasize OAuth via Postiz-hosted flows for cloud).  
3. **Metricool Reddit/Mastodon/Bluesky** — not confirmed on primary platform matrix this pass.  
4. **SocialBee Mastodon** — “Mastodon” string appeared in page chrome; direct-post FAQ list does not include it — treat as **not direct**.  
5. **Hypefury Mastodon** — secondary blogs yes; primary channel list when fetched did not show Mastodon.  
6. **Upload-Post, SocialAPI.ai, Nimply, Blotato, OpenTweet** — 2026 agent/API tools seen in search; not full matrix (out of must-list except Late).  
7. **TikTok app-review timelines** for Mixpost/Postiz self-host — operational, not priced.  
8. **Video worth-it** — explicitly out of angle; YT/TikTok columns only mark capability.
---
## Recommended next action (for weebo)
Deploy **Postiz** on a usectl machine, connect X + LI + Threads + Bluesky first, wire Claude via MCP/API; add IG/Reddit/Mastodon/YT/TikTok as OAuth allows. If cloud preference wins over self-host ops, trial **Zernio** free (2 accounts) + native Mastodon, or **Buffer** Free→Essentials for MCP without ops.
