TryPost is a social media scheduling tool for creators, freelancers, and agencies who want to manage content across multiple networks without juggling separate apps or paying per-channel fees. It's a direct alternative to tools like Hootsuite, and you can self-host it for free or use the managed cloud.

The core workflow is straightforward. Write a post once, preview how it renders on each network, then queue it across Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Pinterest, Threads, Bluesky, and Mastodon from a single editor. Instagram's 4:5 crop and X's 16:9 framing show up in the preview before anything goes live.

Key capabilities:

• Visual calendar with drag-and-drop scheduling. Filter by network or workspace, see a full month at a glance, and reorder posts without rebuilding queues.
• Auto-publishing via each network's official API. Set the time and walk away; you only get notified if something fails.
• AI captions built into the composer, so you're not starting from a blank box.
• Team workflows with real-time co-editing, inline comments, and approval flows. Clients can approve posts through a shareable link without needing an account.
• Media library for storing and reusing images and videos across posts without re-uploading.
• Analytics tracking followers, reach, and engagement across networks in one chart, updated in real time.

For agencies, each client gets a separate workspace with its own brand kit and designated reviewers. Switching between clients takes one click instead of logging in and out of multiple dashboards. Tools like Postiz and Mixpost cover similar ground, but TryPost's approval flow and per-client workspace model are built specifically for the agency use case.

Because it's fully open source, there's no vendor lock-in. You can inspect the code, contribute on GitHub, or deploy on your own infrastructure for complete data control.
