If you're looking for the best open-source alternative to Later, Chronex is a strong place to start. If it doesn't quite fit your needs, there are plenty of other great options worth exploring, including TryPost and OpenPost. We've ranked the top alternatives to help you compare your options and find the right fit.

Chronex

Self-hostable social media scheduler for content creators and small teams with distributed job processing.

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.

TryPost

Open-source social media scheduling platform — a self-hosted alternative to Buffer, Hootsuite, and Later for agencies and creators.

TryPost is a self-hosted, open-source social media management platform built for teams, agencies, and creators who want full control over their content and data. It lets you draft once and publish everywhere — X, LinkedIn, Facebook, Instagram, TikTok, YouTube, Pinterest, Threads, Bluesky, and Mastodon — from a single dashboard with a visual calendar and a multi-platform composer.

The 1.0 release adds a complete first-class API surface: a REST API with personal access tokens, an MCP server for connecting Claude, Cursor, and ChatGPT so you can schedule, publish, and pull metrics with natural language, and built-in AI for caption drafting, on-brand carousel generation, and inline review. Workspaces with role-based permissions, a brand profile that enforces tone and voice across every AI call, and per-account engagement analytics round out the platform.

Unlike commercial schedulers that charge $30–$200 per user per month and keep your content on their database, TryPost is AGPL-3.0 licensed, self-hostable, and has no artificial limits on posts, accounts, or workspaces. Install it on your own server and your drafts, posts, and metrics never leave your infrastructure.

OpenPost

Open-source social media manager for writing, designing, scheduling, and tracking posts — an alternative to Buffer, Canva, and CapCut.

OpenPost is an open-source social media management app that combines post creation, design, video editing, and scheduling in a single workspace. Connect accounts on Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Threads, Bluesky, Mastodon, Pixelfed, PeerTube, Lemmy, PieFed, Discord, Pinterest, and Telegram, then compose posts and threads with per-platform text and media previews before publishing.

Scheduling works through a calendar and queues: pick a publishing time or drop posts into the next free slot, stagger them across accounts, and get reminders when a queue runs low. A built-in inbox reads and replies to supported comments and direct messages, while analytics compare post results and track audience changes. Workflows turn GitHub releases, RSS feeds, and scheduled prompts into drafts on a visual canvas, and an API, TypeScript SDK, CLI, MCP server, and n8n integration cover scripted publishing.

Compared to Buffer, it covers the same scheduling and publishing loop without per-post limits or per-seat fees. Compared to Canva, the layered image editor handles thumbnails and multi-page carousels with templates and custom fonts; compared to CapCut, the multitrack video editor trims clips, adds captions and transitions, and cuts footage by selecting words in its transcript. The screen-and-camera recorder feeds the same timeline. Self-host it with Docker Compose (default setup is a single container with SQLite and local media storage) or use OpenPost Hosted.
