I am not a developer, however I’m a content material creator who’s spent method extra time than I might care to confess experimenting with each social media API I may get my fingers on.
That’s partly as a result of I am serving to form how we’re speaking about Buffer’s API, and partly — OK, largely — as a result of I have been vibe coding my very own little instruments and workflows for months now. As a self-professed instruments nerd, I really like testing and experimenting when new ones hit the market.
One factor I’ve discovered on my travels: to say the social media API area exploded within the final 12 months could be an understatement. There are many contenders within the area, most of them lower than two years outdated, and all of them constructed with builders and AI agent builders in thoughts.
However there’s loads of nuance in social media APIs. Some are constructed for solo builders constructing one software, whereas others cater to companies managing dozens of shopper accounts. Some ship MCP servers able to plug into Claude or your agent of selection; others do not. The reply to which social media API is greatest isn’t one-size-fits-all.
So let’s get into the weeds: This is the rundown of each social media API value realizing about proper now, and my ideas on what each is greatest for.
The brief reply
One of the best social media API relies on what you are constructing and the way a lot polish you want. Buffer is the strongest free-tier choice from a longtime model, with a public MCP server, CLI, and 11 supported channels. Ayrshare is probably the most mature for enterprise groups that want analytics and remark administration. Postiz is a good open-source choice, with 30+ platforms and a free self-hosted model. Add-Publish and Zernio are sturdy newcomers for indie devs and AI agent builders.
Key takeaways
- Most unified social media APIs vary from free (like Buffer) to $30/month entry pricing, with Ayrshare and Phyllo on the enterprise finish ($149/month+ and customized quote, respectively).
- MCP server help is the fastest-growing new function. Buffer, Add-Publish, Zernio, and Genviral all ship MCP servers in 2026, letting you join AI brokers like Claude or Cursor on to a posting workflow.
- Buffer’s API is obtainable on each Buffer plan (free accounts get 1 API key, paid accounts get 5). Buffer can also be the one established model with a totally open MCP server.
- Postiz is the one totally open-source choice, with 30+ platforms supported, self-hosting out there, and a cloud model beginning at $29/month.
- Phyllo is just a little completely different: it pulls creator information (viewers demographics, content material efficiency, earnings) fairly than publishing content material. Price realizing about in case your product wants creator analytics.
Earlier than we get into the crux of issues, I hope devs studying this can forgive me for explaining a few issues for my fellow vibe-coders. If you happen to’re an engineer, skip to the instruments record.
A social media API (brief for software programming interface) is a method for one piece of software program to speak to a different.
On this case, your app talks to social networks like Instagram, TikTok, X, or LinkedIn so you are able to do issues programmatically that you just’d usually do by logging into every app: publish posts, schedule content material, pull analytics, handle feedback, or add media.
Each main social community has its personal native API that means that you can do most of our a few of that. Meta’s Graph API covers Instagram and Fb. X, LinkedIn, TikTok, YouTube, Pinterest, Threads, and Bluesky all have their very own.
They’re free for probably the most half (X has pay-per-use pricing), however each has its personal login circulate, charge limits, and… particular quirks. If you wish to publish to all of them from a single app, that is a minimum of eight separate integrations to construct and preserve.
That is the place unified social media APIs are available in. They sit on prime of the native APIs and provide you with one constant approach to discuss to all of them. I like to consider it pretty much as good cable administration: as a substitute of a tangle of mismatched wires, you’ve one multiplug that handles and connects every little thing.
Buffer, Ayrshare, Postiz, and the remainder of the instruments on this comparability are all several types of multiplugs. That’s why I’m zeroing in on these for this text.
A handful of them additionally do different helpful issues on prime of publishing, like pulling creator analytics, producing AI content material, managing feedback and DMs, or letting your AI agent publish in your behalf through an MCP server.
We’ll get into all of that within the comparability under.
API vs. MCP server: what is the distinction?
An API is how your code talks to social networks. An MCP server is how your AI agent talks to social networks, normally via that very same API.
Once you construct a conventional app or workflow, you write code in Python, JavaScript, or one other language to name the API instantly. You deal with the auth, format the info, parse the response, and deal with errors your self.
It’s just a little completely different while you construct with AI brokers like Claude or Cursor. You are probably not writing all that integration code anymore. You are giving the agent entry to instruments and asking it (in plain language) to make use of them. The MCP server, brief for Mannequin Context Protocol server, is the standardized layer that lets the agent “name” these instruments with out customized integration code for each single one.
So an MCP server for Buffer does not exchange Buffer’s API. It sits in entrance of it and exposes it in a format an AI agent can perceive and use.
That is why “MCP server” seems as its personal column within the comparability desk under. If you happen to’re vibe-coding with Claude, an MCP server is what makes your agent capable of publish to social networks in your behalf with out you writing wrapper code. If you happen to’re constructing a conventional app, you may use the API instantly, and the MCP server issues much less (although it does not harm to have one if you happen to would possibly add AI agent options later).

Buffer
Finest for builders, vibe-coders, and no-code builders who need reliability and polish
Platforms: 11 — Instagram, Fb, LinkedIn, TikTok, X, Threads, Bluesky, Pinterest, YouTube, Google Enterprise Profile, Mastodon.
Pricing: Free customers get 1 API key. Paid customers get 5 API keys.
Buffer’s API makes use of GraphQL (a contemporary method for apps to question and share information), and the present model covers publish creation, scheduling, content material concepts, and primary account and channel metadata. We’ve been rebuilding the API from the bottom up over the previous few months, with a deal with documentation, AI-tool readiness, and developer-friendly tooling.
And if you happen to’re working from the command line, the brand new CLI (Command Line Interface) means Buffer matches into your stack the identical method each different dev software does: scriptable, version-controllable, and automatable. Posting to Buffer as a part of a deployment script is now a one-liner. A lot of the API-only instruments on this comparability do not have a CLI in any respect.
On the opposite finish of the spectrum, we have now ready-made integrations with N8N, Zapier, and Make, if you happen to’re after a extra plug-and-play expertise.
I have been constructing with the API and MCP for a number of months now (a weblog and publication content material calendar, plus a private content material OS that connects instantly with Buffer), and it has been completely seamless.
I am not the one one, both! Marin Nedelev, advertising and marketing coordinator at Atena, constructed a reporting system that changed hours of handbook work throughout 77 channels in 9 nations. Shivani Shah, a content material creator, constructed a Friday morning Slack bot that tells her what she posted that week, plus a complete LinkedIn analytics app on Lovable.
Certain, I’m biased, however I really like how reliable the Buffer API is. It is smart — it is the one API on this record from a model with 15+ years of social media integration expertise. Buffer is an official accomplice of each main social community, which isn’t true for most of the newer instruments
Plus, constructing with Buffer means you have already got a working dashboard you should utilize alongside the API and no matter software or workflow you’re constructing, if you happen to want it. Each different software on this record is API-only or has a a lot rougher UI.
If you happen to construct one thing on Buffer’s API, your customers also can log in to Buffer’s internet app to handle their social media accounts with out you having to construct your individual dashboard.
Trustworthy limitations: Social media analytics aren’t out there through the API (but — we’re hoping to make these out there via the API quickly)! You’d want to tug these individually or use the native Buffer dashboard.
Ayrshare
Finest for companies and enterprise groups that want full analytics
Platforms: 13+ — Instagram, Fb, X, LinkedIn, TikTok, YouTube, Pinterest, Reddit, Telegram, Snapchat, Google Enterprise Profile, and extra.
Pricing: Premium begins at $149/month. Enterprise begins at $499/month (generally listed at $599/month for 30 social profiles). There is a free tier, however it’s restricted to picture posts and 20 posts per 30 days, which makes it primarily helpful for testing.
Ayrshare is the longest-running API-first participant on this area. Software program Growth Kits (SDKs) can be found for Node.js, Python, PHP, C#, Go, Java, and Ruby on Rails (the widest SDK protection of anybody on this record).
The function set goes past publishing, with remark and overview administration, messaging with auto-responses, superior analytics, and hashtag automation.
If you happen to’re an company managing dozens of shopper social profiles and also you want granular analytics + DM dealing with + webhooks in a single place, that is the place you could possibly in all probability justify Ayrshare’s premium worth.
Trustworthy limitations: The catch is worth. At 50 social profiles, Ayrshare runs about $770/month, which makes it costly for B2C merchandise with hundreds of buyer accounts. And as of Might 2026, there isn’t any MCP server.
Postiz
Finest open-source choice for full information management
Platforms: 30+ — together with X, LinkedIn, Instagram, Fb, TikTok, YouTube, Pinterest, Threads, Bluesky, Mastodon, Discord, Nostr, and Farcaster.
Pricing: Free if self-hosted. Cloud begins at $29/month for five accounts and 400 posts (14-day trial).
Postiz is a strong choice, and it’s open supply. The total supply code lives on GitHub, and you may deploy it on Railway, your individual server, or anyplace you’ll be able to run Docker. Each paid plan consists of an API for creating posts, importing media, and managing integrations, and it integrates with n8n and Make.com if you happen to’d fairly wire it up through no-code automation.
The platform record is the widest I’ve encountered. Like Buffer, it covers Mastodon and Bluesky — however Postiz goes additional with Nostr and Farcaster too, making it the broadest API on this record for decentralized networks.
Trustworthy limitations: Self-hosting means you are accountable for uptime, scaling, and platform API modifications breaking your builds. Value can also be an element, because the cloud model begins cheaply however climbs shortly if you happen to want greater than 5 accounts.
Add-Publish
Finest free tier with an open-source MCP server
Platforms: 10 — TikTok, Instagram, YouTube, LinkedIn, Fb, X, Threads, Pinterest, Reddit, Bluesky.
Pricing: Free tier with 10 uploads/month. Paid plans begin at $16/month (billed yearly).
Add-Publish is among the strongest newcomers. It is API-first, ships Python and JavaScript SDKs out of the field, has 30,000+ customers, and runs an open-source MCP server, with 40 instruments for AI brokers. That MCP server (hosted on GitHub for auditing) makes Add-Publish one of many extra fascinating choices if you happen to’re plugging Claude or Cursor right into a publishing workflow.
Trustworthy limitations: The free tier caps at 10 uploads per 30 days, which is beneficiant for having a mess around, however not ultimate for something past private use. And whereas the platform record covers the mainstream networks, it is narrower than Postiz’s 30+ if you happen to want rising or decentralized networks.
Zernio
Finest for paid marketing campaign administration
Platforms: 15 — X, WhatsApp, YouTube, Pinterest, Snapchat, Meta Adverts, TikTok Adverts, Instagram, LinkedIn, Threads, Bluesky, Google Enterprise, Google Adverts, Pinterest Adverts, TikTok, Fb, Reddit, Telegram, Discord, LinkedIn Adverts, X Adverts
Pricing: Begins at $19/month.
Zernio (previously Getlate.dev) markets itself to indie builders and AI agent builders, with a flat $19/month entry level.
Zernio affords connectivity to varied advert platforms, together with Meta Adverts, TikTok Adverts, Google Adverts, Pinterest Adverts, LinkedIn Adverts, and X Adverts. It’s the one software on this record to take action, so it’s an important name if you happen to’re extra involved with paid than natural content material.
It ships a devoted MCP server alongside the REST API, making it helpful if you happen to’re plugging Claude, ChatGPT, or different brokers right into a publishing workflow.
Trustworthy limitations: Zernio is a more moderen choice with a smaller neighborhood.
Phyllo
Finest for social media analytics
Platforms: 20+ — YouTube, Instagram, TikTok, Twitch, Fb, and different long-tail creator platforms.
Pricing: Customized, sales-gated.
Phyllo is not technically a posting API. It is a creator information API that pulls viewers demographics, engagement stats, content material efficiency, and earnings information (the place out there) instantly from the platforms. If you happen to’re constructing a creator market, an influencer analytics software, or something that should show actual viewers information from a creator’s profile, Phyllo is in a class of its personal.
Trustworthy limitations: Pricing is gated behind a gross sales name, which is ok for enterprise procurement however irritating for indie devs who simply wish to see if it matches the funds. And since it is data-focused, you’ll be able to’t use it to really publish content material. You’d pair it with one of many publishing APIs on this record.
Publish for Me
Finest for indie SaaS with predictable per-post pricing
Platforms: 9 — TikTok, Instagram, Fb, X, LinkedIn, YouTube, Threads, Pinterest, Bluesky.
Pricing: $10/month for 1,000 posts. Plans run $10 to $1,000/month with limitless accounts and limitless API keys.Publish for Me
Finest for indie SaaS with predictable per-post pricing
Platforms: 9 — TikTok, Instagram, Fb, X, LinkedIn, YouTube, Threads, Pinterest, Bluesky.
Pricing: $10/month for 1,000 posts. Plans run $10 to $1,000/month with limitless accounts and limitless API keys.
Publish for Me costs on publish quantity fairly than profile depend, which works properly when you’ve got many low-activity accounts. Limitless accounts and limitless API keys are included on each plan, with no per-seat payment, which is absolutely useful if you happen to’re constructing a SaaS app and don’t desire pricing surprises as you develop.
Trustworthy limitations: The platform record is shorter than the larger gamers. No MCP server but. And whereas the per-post pricing is predictable, you may wish to tread fastidiously when you’ve got high-volume accounts.
Outstand
Finest for pay-as-you-go publishing
Platforms: 10 — X, LinkedIn, Instagram, Fb, TikTok, YouTube, Threads, Bluesky, Pinterest, Google Enterprise Profile.
Pricing: $0.01 per publish.
Outstand’s per-post pricing is fairly uncommon on this market. For a low-volume aspect mission or a proof-of-concept construct, it might are available in underneath any flat paid plan. For a high-volume product, the mathematics will get much less pleasant, and also you’d wish to evaluate it fastidiously in opposition to Postiz self-hosted or Publish for Me’s flat plans.
Trustworthy limitations: No MCP server. Pricing mannequin favors sporadic publishing; at scale, you are higher off on a flat plan.
Genviral
Finest for AI-generated content material workflows
Platforms: 6 — TikTok, Instagram, YouTube, Pinterest, LinkedIn, Fb.
Pricing: Customized (varies by utilization).
Genviral is probably the most explicitly AI-native choice on this record. The API features a full content material pipeline: producing AI slideshows, managing picture packs, creating reusable templates, rendering remaining property, and monitoring analytics throughout all six platforms. There is a TikTok draft mode (you’ll be able to add trending sounds earlier than publishing) and direct posting to the opposite 5.
It is constructed round an OpenClaw integration with 42+ instructions for AI brokers, which makes it fascinating in case your product’s core loop is “AI generates content material, then publishes it.”
Trustworthy limitations: Smaller platform protection (6 vs. the 10-30 vary of opponents). No public pricing tier record, so that you’d want to speak to gross sales. And the deal with AI-generated content material means it is in all probability a bit a lot if you happen to simply wish to programmatically schedule present posts.
PostEverywhere
Finest for predictable month-to-month plans with AI inbuilt
Platforms: 7 — Instagram, X, LinkedIn, Fb, TikTok, YouTube, Threads.
Pricing: Starter $19/month (10 accounts, 50 AI credit, limitless posts). Progress $39/month (25 accounts, 500 AI credit). Professional $79/month (40 accounts, 2,000 AI credit). All plans embrace limitless posts and full API entry. 7-day free trial.
PostEverywhere is probably the most “all-inclusive” plan on this record. API entry is included on each tier, AI picture technology is inbuilt, and charge limits are beneficiant: 60 requests/min, 1,000/hr, 10,000/day.
Trustworthy limitations: Solely 7 platforms. No MCP server. AI credit are restricted on the decrease tiers, which might pinch if you happen to’re utilizing the picture technology closely.
Right here’s a useful framework if you happen to’re nonetheless uncertain which one would possibly work greatest for you:
- If you need a free tier from a model you’ve got heard of, begin with Buffer or Add-Publish. Each are free for low quantity, each have MCP servers, and each come from groups actively sustaining their developer expertise.
- If you happen to’re constructing for enterprise groups that want analytics, Ayrshare is the secure selection. It is costly, however the function set goes deeper than anybody else on this record.
- If you need full management and do not thoughts working your individual infrastructure, self-hosted Postiz is unbeatable on value (free) and platform protection (30+).
- If you happen to’re constructing an AI agent, the MCP server issues. Buffer, Add-Publish, Zernio, and Genviral all ship one. Strive every in your dev surroundings and see which docs land greatest.
- If you happen to want viewers information (not simply posting), Phyllo is the one one on this record constructed for that.
- In case your pricing mannequin must be uncommon (very excessive account depend, very bursty publishing, very predictable month-to-month), take a look at Publish for Me, Outstand, or PostEverywhere, respectively.
