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).

Per-tool sections
1. Postiz
- Platforms: 32 documented providers including X, YouTube, TikTok, LinkedIn, Threads, Bluesky, Instagram, Reddit, Mastodon (docs).
- Agent: Public REST API (all paid cloud plans + self-host), Node SDK, MCP, agent CLI, n8n custom node, Make/Zapier (postiz.com, GitHub).
- Hosting: AGPL open-source self-host or cloud. GitHub ~35k★ (repo).
- Price: Standard $29/mo (5 channels, 400 posts), Team $39 (10 ch, unlimited posts), Pro $49 (30), Ultimate $99 (100). Annual ~20% off. Self-host: no license fee (postiz.com FAQ).
- Media: Upload endpoint; images + short AI video credits on cloud; YT/TikTok settings in API.
- Scheduling / analytics: Calendar + evergreen; per-channel analytics from platform APIs.
- Catch: Cloud channel count = each connected account; self-host means you maintain Temporal/Postgres/Redis and platform OAuth apps. Create-post rate limit ~90–100 req/hr (API intro).
- X: Supported (
__type: x). How cloud Postiz bills underlying X API cost is not spelled out on the pricing FAQ — treat as “included in subscription until stated otherwise” (single-source gap).
2. Mixpost
- Platforms: Lite: Facebook Pages, X, Mastodon. Pro/Enterprise: + Instagram, LinkedIn, YouTube, TikTok, Pinterest, Threads, Bluesky, GBP (pricing FAQ).
- Agent: REST API (docs.mixpost.app/api), MCP server (mixpost.app/mcp).
- Hosting: Self-hosted only (PHP/Laravel).
- Price: Lite free OSS; Pro $299 one-time (1 yr updates); Enterprise $1,199 (pricing).
- Media / scheduling / analytics: Full on Pro.
- Catch: You register your own developer apps with Meta, TikTok, Google, X, etc. TikTok/Meta app review can take days–weeks (Upload-Post comparison citing Mixpost ops).
- X: Dedicated guide for Pay as you go X API; paste API Key/Secret into Mixpost (X integration docs). You pay X credits directly.
3. Buffer
- Platforms (API): Instagram, Threads, LinkedIn, X, Facebook, TikTok, GBP, Mastodon, YouTube, Pinterest, Bluesky — 11 (support article). No Reddit.
- Agent: GraphQL at
api.buffer.com, API keys on all plans, MCP, CLI, n8n/Make/Zapier/Claude/Cursor (buffer.com/api, pricing).
- 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).
- Media: Images/videos via public URL (no direct multipart upload via API).
- Analytics: Strong in UI; API analytics experimental / not recommended for production (support).
- Catch: Per-channel math; Reddit gap; media hosting requirement.
- X: Included on Free and paid; Buffer states official partner status with X (developers page).
4. Typefully
- Platforms: X, LinkedIn, Threads, Bluesky, Mastodon (scheduling page; API help). No YT/TikTok/Reddit; IG “soon.”
- Agent: REST v2 (Dec 2025), webhooks, MCP (
mcp.typefully.com), Agent Skills (ai-agents, 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).
- 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).
- 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).
- 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). No Reddit.
- Agent: REST API on Business & Enterprise (API launch post).
- Price: Professional starts $5/mo/account; Business $10/mo/account (help center). 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).
- Platforms: twitter, instagram, facebook, linkedin, tiktok, youtube, pinterest, reddit, bluesky, threads, googlebusiness, telegram, snapchat, whatsapp, discord, slack — no Mastodon (docs, platforms).
- Agent: REST
/api/v1, SDKs, CLI, webhooks, MCP (marketing claims 280+ tools), n8n node (zernio.com/social-media-api).
- Price: Accounts 1–2 free; 3–10 $6 each; 11–100 $3; 101+ $1 (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, X 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). 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). 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, connect X).
9. Metricool
- Platforms: Broad scheduler (IG, TikTok, YT, LI, etc.); Free plan no LinkedIn, no X (plans help).
- Agent: MCP on any plan; REST API only Advanced/Custom (same).
- Price: Starter from ~$20–25/mo (annual/monthly); Advanced from ~$53/mo (metricool.com/metricool-premium).
- X: Add-on €10/$10 per X account per month (or $120/yr) on Starter+ (X access, add-on guide).
- 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, home).
- 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).
- 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); 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.

Who lost X entirely
Ranked shortlist for agent-run accounts (this brief)
- Postiz self-hosted on usectl — only full 9-network matrix + API/MCP/CLI; aligns with “self-hosting is easy.”
- Zernio — best pure API/MCP DX; free tier; accept Mastodon via native client or second hop; budget X link costs.
- 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
- Typefully exact list prices — pricing page did not yield stable dollar amounts via fetch/curl; used third-party figures — verify in UI.
- 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).
- Metricool Reddit/Mastodon/Bluesky — not confirmed on primary platform matrix this pass.
- SocialBee Mastodon — “Mastodon” string appeared in page chrome; direct-post FAQ list does not include it — treat as not direct.
- Hypefury Mastodon — secondary blogs yes; primary channel list when fetched did not show Mastodon.
- Upload-Post, SocialAPI.ai, Nimply, Blotato, OpenTweet — 2026 agent/API tools seen in search; not full matrix (out of must-list except Late).
- TikTok app-review timelines for Mixpost/Postiz self-host — operational, not priced.
- 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.
Research method: WebSearch + WebFetch + curl on official docs/pricing; no browser; no threadbus; 2026-09-05.
