Integrating social networks without surprises
Guides, comparisons and engineering notes on the Facebook, Instagram, LinkedIn, TikTok, X, WhatsApp, YouTube, Google Business, Bluesky and Discord APIs: what they really cost, what limits they have and how to publish without breaking anything. Every article shows the date it was verified.
Postiz alternatives in 2026: hosted, self-hosted and MCP
Postiz is free to self-host, but every network still wants your own developer app and its review. Seven alternatives, hosted and self-hosted, priced.
Ayrshare alternatives in 2026: pricing, free tiers and MCP
Ayrshare alternatives compared by price floor, billing unit, API access and MCP. Several start free with API access; Ayrshare starts at $149/month.
Buffer alternatives in 2026: for your own channels, and for your customers'
Buffer sells API keys on every plan, free included, but they only reach your own channels. Third-party access has been closed since 2019. Six alternatives split by which of those two problems you have. Prices verified September 15, 2026.
Hootsuite alternatives in 2026: the problem is that it bills per seat
Hootsuite is $99 per user per month on Standard and $249 on Advanced, billed annually, so the bill multiplies by headcount, not by work. Eight alternatives that charge for something else, with the arithmetic at four people. Prices verified September 15, 2026.
Metricool alternatives in 2026: one list for marketers, another for developers
People look for a Metricool alternative for two unrelated reasons: the bill grows per brand, or they hit the wall where the API needs Advanced. Those are different problems with different answers. Prices verified September 15, 2026.
Character limits across social APIs: .length lies, and it lies both ways
One emoji is 11 UTF-16 units, 1 grapheme and 25 bytes. Bluesky counts graphemes and bytes at once, Threads counts graphemes, Telegram changes its limit when you attach a photo, and Slack does not fail at all. What each network really measures, measured against the real APIs.
Ayrshare's MCP server: there are two, and one of them cannot post
Ayrshare ships a Documentation MCP and an Action MCP, and connecting the wrong one leaves your agent reading docs instead of publishing. What each does, what the Action MCP costs, and how it compares to PlanVortex's 28 tools. Verified September 15, 2026.
Buffer's API in n8n: fine for your channels, closed for your customers'
There is an official Buffer node for n8n and it works. What it cannot do is publish on behalf of your users: Buffer's third-party access has been shut since 2019 and the new API is a personal-key beta. What to do instead. Verified September 15, 2026.
Metricool's MCP with Claude: what it does, and where it stops
Metricool's MCP works on every plan, free included, and it publishes. The API behind it needs Advanced. Which of the two you actually need depends on one question: whose accounts are these? Verified September 15, 2026.
Social media APIs for agentic workflows: the four things that actually decide it
An agent publishing to social needs things a dashboard never needed: an action server rather than a docs one, onboarding over the API, a small blast radius, and a way to ask what each network allows. How Ayrshare, Metricool, Buffer, Postiz and PlanVortex compare. Verified September 15, 2026.
PlanVortex vs Metricool for embedding social publishing in your product
Metricool has 3.5 million users, ads and deeper analytics. Its API starts at €43/month and, in its own words, cannot build the social-network connection flow. What that means if you are an integrator, verified September 3, 2026.
PlanVortex vs Postiz: the real cost of self-hosting a social publishing tool
Postiz is AGPL open source with 35k stars and self-hosts for free. The licence is free; the developer app on every platform's portal is not. What self-hosting actually costs an integrator, verified September 3, 2026.
PlanVortex vs Zernio: one writes the posts, the other does not
PlanVortex writes the copy and generates the images; Zernio has no AI of any kind, but covers more platforms (16) and sells ads, SMS and voice. Price tier by tier, multi-tenancy, libraries and what each one is missing, verified September 3, 2026.
AI social posts from your own photos (without letting it invent the picture)
The AI writes the copy and you supply the picture. Why a generated image gives the brand away, how to describe each photo so the copy works, how many posts come out of N photos and what it costs.
Posting to social media from your AI assistant with an MCP server
A guide to the official PlanVortex MCP server: what MCP is, how to set it up in Claude Desktop, Claude Code, Cursor and VS Code, the 25 tools it ships, and why it deletes nothing.
PlanVortex vs Ayrshare for publishing to social from your own product
$149/month with no free tier vs an API that PlanVortex ships on all four plans, the free one included: pricing, networks, libraries, MCP server, and AI across both APIs, verified September 3, 2026.
