Mallary

Mallary is a social media automation API that lets you publish to ten platforms, including YouTube, Facebook, Instagram, TikTok, LinkedIn, X, Pinterest, Threads, Reddit, and Snapchat, with one API call. Instead of learning each platform's quirks and managing a stack of OAuth tokens, you send a single payload and Mallary handles the rest, adapting formats, refreshing credentials, and retrying failed requests automatically.

The core promise is unification. A lot of social automation tools expose separate endpoints for each network, which means your code ends up full of conditionals and edge cases. Mallary abstracts that away. You describe what you want to post, where it should go, and when, and the API figures out what each platform actually needs. That includes platform-specific formats like YouTube Shorts, Instagram Stories, and TikTok carousels with auto-added music.

Beyond publishing, the API handles comment management. You can pull comments from six platforms, reply to them programmatically, or attach comments under a new post when you publish. Higher-tier plans add AI-powered auto-replies that can respond in your brand voice without manual intervention, which is useful if you run accounts at scale and cannot keep up with every notification.

Access comes in three tiers. Starter at ten dollars a month gives you four accounts per platform and 120 posts per month, along with scheduling, analytics, and a web dashboard. Pro at twenty-four dollars removes the post cap, adds AI auto-replies, and supports ten accounts per platform. Business at eighty-two dollars expands to fifty accounts per platform with faster processing for high-volume workflows. All plans include a 14-day free trial and a 30-day money-back guarantee.

The developer surface goes beyond a REST API. There is a CLI for terminal automation, an MCP integration for AI agents, and native nodes for n8n, Make.com, and Zapier. That makes it fit into both hand-coded pipelines and no-code automation setups. Mallary is officially verified by Meta, Google, LinkedIn, TikTok, Pinterest, and X, so you are working with sanctioned API access rather than scraping or workarounds.

Limitations are honest. Reddit and Snapchat support is listed as coming soon, not ready. The Starter plan caps posts at four per day. AI auto-replies require Pro or above. And rate limits apply per user, per minute, so bursts still need throttling on your side.
