About

PostUno is a web-based social media publishing and scheduling tool for creators, small teams, businesses and agencies managing multiple brand profiles. Users can upload a photo or video once, prepare a caption, choose supported destinations, then publish immediately or schedule the post for a selected time. The service connects to Facebook, Instagram, YouTube, TikTok, Threads, Pinterest, X and LinkedIn, and organizes client and personal accounts in separate brand profiles. A calendar provides a view of scheduled posts, while platform-level status and results help users identify and retry failed publishing jobs. Developers can publish and schedule through a documented API, receive outbound webhooks, or automate workflows using n8n, Make, Zapier and Airtable. Post previews and platform-specific publishing options help prepare content for cross-network distribution; supported content types and formats vary by network.

About

Zernio is a unified social media API platform that enables developers and AI agents to publish, schedule, and manage content across 14+ social networks through a single integration. Instead of building separate integrations with each platform, developers make one API call and Zernio handles authentication, media formatting, rate limits, and platform-specific requirements. The platform supports post scheduling, content management, comments and DMs automation, analytics tracking, ads management, and media uploads. It integrates with Instagram Business and Creator APIs, TikTok Business API, LinkedIn, YouTube, Twitter/X, Facebook, Pinterest, Reddit, Threads, Bluesky, and WhatsApp Business API. Features include automatic token refresh, webhook notifications, and rate limit management. Built for SaaS companies, agencies, and AI agent builders, the product is fully white-label.
