Later

Chronex is an open-source social media scheduling tool that lets you compose, schedule, and automatically publish posts across multiple platforms from a single dashboard.

It supports Instagram, Threads, LinkedIn, Slack, Discord, and Telegram, with media uploads handled via Backblaze B2. Post scheduling is powered by Cloudflare Queues, giving it a robust distributed job processing backbone.

Built with Next.js 16, TypeScript, and tRPC on the frontend, and Drizzle ORM with PostgreSQL (via Neon) on the backend — Chronex is a self-hostable alternative to commercial tools like Buffer, Later, and Hootsuite.
