Get late is great. Terrific pricing, easy to use. Easy to upload social posts by CSV or through API (or even through their GUI). I switched from metricool because of their built in queue functionality. Very cool.

Zernio information
What is Zernio?
LZernio 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 REST API integration. Instead of building and maintaining separate integrations with each platform's API, developers make one API call and Zernio handles authentication, media formatting, rate limits, and platform-specific requirements.
The platform supports a comprehensive range of social media functionality, including post scheduling and publishing, content management, comments and DMs automation, analytics tracking, ads management, and media upload and management. It integrates with Instagram Business and Creator APIs, TikTok Business API, LinkedIn Company and Personal APIs, YouTube Data API, Twitter/X API, Facebook Graph API, Meta Business Suite, Pinterest API, Google My Business API, Reddit API, Threads API, Bluesky API, and WhatsApp Business API.
Zernio addresses the complexity of building direct integrations with social media platform APIs, where each platform has its own OAuth flow, media format requirements, content rules, rate limits, and frequent breaking changes. Building custom integrations across all major platforms typically takes 8–12 months of engineering time and requires ongoing maintenance. Zernio abstracts this behind a single API, reducing integration time to under an hour.
The platform includes automatic token refresh, rate limit management, real-time webhook notifications, developer-friendly SDKs, and comprehensive API documentation. It is designed for SaaS companies embedding social features into their products, agencies managing client accounts at scale, and AI agent builders who need programmatic social posting. Zernio operates as a white-label solution, meaning end users never see Zernio branding. It offers both free and paid plans with usage-based pricing.
