Ayrshare alternatives (2026): social media posting APIs compared
12 alternatives to Ayrshare’s social media API from their own pages: price, free tier, networks, MCP, webhooks, limits and white-label.
By Mellow · UpdatedThe short answer
Ayrshare sells one API for publishing to many social networks, priced by profile. The 12 alternatives below differ from it, and from each other, in five ways: what the bill counts (a profile, a connected account, a channel or each post); whether a free tier lets you build before you pay; how many networks one call reaches; whether your customers connect their own accounts under your name; and whether an AI agent can post through a hosted MCP server that signs in with OAuth.
For reference, Ayrshare’s own pages: Premium: "$149/mo" billed monthly, for 1 social profile, with the API. Posting for your own users starts at Launch: "$299/mo" for up to 10 profiles. The yearly toggle says "Save 17%".

Disclosure: Mellow publishes this page and makes Mellow Hub, one of the APIs below. Mellow Hub itself runs on Post for Me’s API, another row in this table: Hub’s channels connect through it, and it carries Hub’s posts to every network except Telegram (Mellow’s own bot) and Instagram accounts that also signed in to Mellow’s own Meta app. Mellow’s code also keeps optional adapters for Postproxy’s and SocialAPI’s APIs. Hub’s row comes from its own code and pricing configuration. Every other cell links to the vendor’s own page, read signed out on 10 November 2026; where a vendor’s pages disagree or say nothing, the cell says so. Rows are in alphabetical order, not ranked.
Ayrshare and 12 alternatives, side by side
Prices are each vendor’s list price in its own currency, read on 10 November 2026. Check the vendor’s page before you build on it: prices, limits and plans change. The comparison is split into two tables so that each stays readable; both list the same 13 APIs in the same order.
Price, free tier, networks and limits
| API | Cheapest plan with the API | Free tier or trial | Networks | Rate and usage limits |
|---|---|---|---|---|
| Ayrshare | Premium: "$149/mo" billed monthly, for 1 social profile, with the API. Posting for your own users starts at Launch: "$299/mo" for up to 10 profiles. The yearly toggle says "Save 17%". Sources: Ayrshare: pricing, Ayrshare: Launch plan docs | No free plan: Basic "is no longer available to new sign-ups". Launch has a "28-day free trial"; Premium, Business and Enterprise are "billed at signup (no free trial)". Whether the trial needs a card is not published. Sources: Ayrshare: pricing, Ayrshare: Basic plan help | "14 social networks": Bluesky, Facebook, Google Business Profile, Instagram, LinkedIn, Pinterest, Reddit, Snapchat, Telegram, Threads, TikTok, WhatsApp, X and YouTube.

Sources: Ayrshare: introduction, Ayrshare: networks for /post, Ayrshare: X docs | "300 API requests per 5-minute interval" per User Profile.

MCP clients can sign in with OAuth 2.1 instead. Source: MCP guide | One owner’s brand profiles, each with its own channels; how many depends on the plan. No white-label connection flow, client logins or team seats: Hub is built for publishing your own brands, not for embedding posting in your product.

Which one fits which need
- A free tier to build on. Buffer (3 channels), bundle.social (20 posts a month), Postproxy (10 posts a month), Publora (15 posts a month, no X), SocialAPI (10 posts a month), Upload-Post (10 uploads a month, no TikTok) and Zernio (2 accounts) include the API without paying. Outstand’s pages disagree on a free tier; Postiz can be self-hosted.
- A bill that follows posts, not accounts. Outstand and Post for Me count posts and leave connected accounts unlimited; bundle.social counts posts per organization. Zernio and Publora count connected accounts; Ayrshare, Postproxy, SocialAPI and Upload-Post count profiles; Buffer and Postiz count channels.
- Your customers connect their own accounts. Post for Me’s White Label projects and Postproxy (on 9 networks) can show your own app on the networks’ consent screens; Outstand can with your own app registered. Ayrshare, bundle.social, Upload-Post and Zernio put your logo on a hosted connection page. Publora does this on its Agency plan only; Blotato has no client connection flow.
- The most networks in one call. Postiz lists 31 to 32 platform types, blogs included; Upload-Post says 22; Zernio 16, with Reddit paused; bundle.social 15; Ayrshare 13 to 14. The others reach 9 to 12.
- Keys that reach only part of the account. Zernio’s keys can be limited to profiles, read-only and set to expire; Postproxy’s to one profile group; SocialAPI’s to scopes and brands; Mellow Hub’s to channels, review or autopilot, a daily ceiling and an expiry. Buffer’s, bundle.social’s and Post for Me’s keys reach the whole account, organization or project.
- An AI agent posts through MCP. Hosted servers with OAuth: Blotato, Buffer, Mellow Hub, Outstand, Postiz, Postproxy, Publora, SocialAPI, Upload-Post and Zernio. Ayrshare’s takes an API key only; Post for Me’s and bundle.social’s run locally.
- Open source. Postiz’s code is under AGPL-3.0 and can be self-hosted, though most networks then need your own developer app; Upload-Post’s MCP server is under MIT.
Hootsuite’s API is not in the table. Its REST API is free for approved developers ("Access to the Hootsuite REST APIs is free"), but a developer account waits for approval, and its own overview says TikTok, YouTube and Bluesky are "not supported by the publishing API".

What to check before you build on one
Send one real post through each API you are weighing, to the networks you need, and read what comes back: the table says what each one documents, not how it behaves on your accounts. Ask what happens when a request times out and you retry (an idempotency key returns the first post instead of publishing a second), and whose name your customers see on each network’s consent screen. Mellow Hub’s side of this is in Schedule social media posts with a REST API (idempotency keys and each network’s result) and Publish to social media with an MCP server (what a key may do).
Where Mellow Hub fits, and where it does not
Mellow Hub publishes one post to 10 networks at once, by hand in its composer or through an AI agent, and checks every network’s rules before anything is sent. It is built for agents that publish: each key or OAuth grant is limited to the channels, the mode, the daily ceiling and the expiry its owner chose, and every action is recorded where the owner can revoke it. It is weaker in these ways:
- No free plan. Publishing needs a plan. A new account starts with a 7-day free trial of a monthly plan, which takes a card; a yearly plan is charged the day it is chosen.
- 10 networks. No Google Business Profile, Mastodon, Reddit or Snapchat.
- No inbox and no listening. No shared inbox, comment moderation or monitoring. On Instagram it answers by keyword: a comment gets a public reply and one private message, a direct message gets an answer (comment-to-DM). Analytics are per post.
- No team seats. One owner’s brand profiles, without roles or client logins.
- Newer. Mellow has published live, with public links, to Instagram, YouTube, X, LinkedIn, Threads, Bluesky, Pinterest and Facebook. On TikTok, uploads are accepted but, on our test accounts, visible only to their owner.
See the plans, each network’s rules, or the comparison of publishing APIs if an agent or your own code will do the posting.
Questions
What is the best alternative to Ayrshare?
This page does not rank them, because they answer different needs. To build before paying: Buffer, bundle.social, Postproxy, Publora, SocialAPI, Upload-Post and Zernio include the API on a free tier, each with its own limit. To pay by post rather than by profile: Outstand and Post for Me. For the most networks in one call: Postiz, Upload-Post and Zernio. For your customers’ accounts, look at how each connects them, in the table. Every cell links to the vendor’s own page.
Is there a free alternative to Ayrshare’s API?
On 10 November 2026: Buffer’s free plan includes the API for 3 channels; bundle.social’s free plan has 20 posts a month on 3 accounts; Postproxy’s 10 posts a month; Publora’s Starter 15 posts a month on 3 accounts, without X; SocialAPI’s Hobby 10 posts a month on 2 profiles; Upload-Post’s free plan 10 uploads a month on 2 profiles, without TikTok; and Zernio’s first 2 connected accounts are free. Outstand’s own pages disagree on whether it has a free tier, and Postiz can be self-hosted. Ayrshare (a 28-day trial of Launch), Blotato (a trial without the API), Post for Me and Mellow Hub (a 7-day trial with a card) have no free plan.
Which posting APIs let my customers connect their accounts under my brand?
A network’s own consent screen names the app that asks, so only an API that uses your own app for that network shows your name there. Post for Me’s White Label projects do, on every tier; Postproxy shows your own app on 9 networks or a neutral “Social Media Linker”; Outstand shows its own name unless you register your own app. Ayrshare (from Launch) and bundle.social put your logo on a hosted connection page; Upload-Post (from Professional) and Zernio do too, while the network’s screen still names their app. Publora has client links on its Agency plan; Blotato has no client connection flow.
Which social media posting APIs have webhooks?
Ayrshare (from Launch), bundle.social, Outstand, Post for Me, Postproxy, Publora (paid plans), SocialAPI, Upload-Post and Zernio send events about posts, such as one being published; Upload-Post makes a single delivery attempt. Postiz fires a webhook when a post publishes, without named events. Buffer documents no webhooks, Blotato’s docs say to poll a post’s status, and Mellow Hub has none: you read each network’s result from the post.
Which of them can an AI agent use from Claude or ChatGPT?
Those with a hosted MCP server that signs in with OAuth, which claude.ai and ChatGPT connectors need: Blotato, Buffer, Mellow Hub, Outstand, Postiz, Postproxy, Publora, SocialAPI, Upload-Post and Zernio. Ayrshare’s hosted MCP server takes an API key only, and its own docs say personal claude.ai and Claude Desktop connectors cannot authenticate. Post for Me’s and bundle.social’s MCP servers run locally, with an API key.
How do social media posting APIs charge?
By what makes the bill grow. Per profile, a brand or customer with several networks: Ayrshare, Postproxy, SocialAPI and Upload-Post. Per connected account: Zernio and Publora. Per channel: Buffer, and Postiz’s plans by number of channels. By posts: Outstand (posts above those included are billed one by one), Post for Me (tiers of successful posts a month) and bundle.social (posts a month per organization). Flat plans with an account cap: Blotato. Mellow Hub: plans by brand profiles, with unlimited publishing under a fair-use ceiling.
Does Mellow Hub use Post for Me?
Yes. Mellow Hub runs on Post for Me’s API: Hub’s channels connect through it, and it carries Hub’s posts to every network except Telegram, which goes through Mellow’s own bot, and Instagram accounts that also signed in to Mellow’s own Meta app. On top of it Hub adds brand profiles, its own MCP server, and keys each limited to channels, review or autopilot, a daily ceiling and an expiry, with every action in a journal the owner reads. A product that posts for its own customers is the job Post for Me’s API is built for; Hub is built for publishing your own brands.
