Postcron

Postcron is a social media scheduling and publishing tool that lets marketers, agencies, and small businesses plan, schedule, and automatically publish content across Instagram, Facebook, X (Twitter), LinkedIn, Pinterest, and TikTok from a single dashboard. It supports bulk uploading up to 1,000 posts from Excel or Google Docs, multi-account and team management, automatic image watermarking, a browser extension, and mobile apps for iOS and Android. Originally a Y Combinator / 500 Global-backed startup, Postcron is a consumer- and SMB-facing publishing product; it exposes an internal application API used by its own clients but does not publish a documented public developer API, OpenAPI specification, SDKs, or a developer portal.
