Introducing TryPost.it 🚀

An open source tool to run your social media on autopilot.

Today I’m launching TryPost 1.0. It’s the first version that finally feels close to what I’ve been trying to build all along. If you don’t know TryPost yet, this post is a quick tour of what it does and why it exists.

What TryPost is

TryPost is an open source social media tool I built entirely on my own over the last few months. It runs your whole social media operation on autopilot, from writing posts to publishing across every major platform, with AI doing the heavy lifting and a workflow that scales from one creator to a full agency.

The goal was simple: one place to plan, write, schedule, and publish across every social network, without juggling tabs, copying captions across apps, or paying for five different tools to cover what should be one.

What’s in 1.0

🌐 Publishing to every major platform. Instagram, X, LinkedIn, TikTok, YouTube, Facebook, Pinterest, Threads, Bluesky, and Mastodon. Every post type, all from the same composer.

🤖 AI in every step. Generate captions, images, and full carousel scripts (hook, development, proof, CTA) in your brand voice. Every generation pulls from the tone, language, and colors you set in your Brand Profile, so it sounds like you wrote it.

🗂️ Workspaces. If you manage multiple brands, clients, or projects, each one gets its own space with its own social accounts, posts, team, and roles. Data stays scoped per workspace, and updates sync across everyone’s screens in realtime.

🔌 REST API and a native MCP server. Publish posts from your own scripts, or plug TryPost into Claude, Cursor, or ChatGPT through MCP and let an AI assistant schedule your week.

✨ A pile of smaller wins. GitHub OAuth login, TikTok photo carousels with the new Content Sharing API, Pinterest publishing, a better post viewer, duplicate in one click, and realtime status updates so you stop refreshing the queue.

Built solo, open source

TryPost is open source. The code is on GitHub, anyone can read it, fork it, or run it themselves. I built every line of it entirely on my own. The cloud version is how the project pays for itself, but the option to run it locally is always there.

I built this because I wanted the tool to exist for myself first. After a few months of grinding, this release is the closest the product has been to that vision.

Try it

If you create content, manage social for a brand, or run an agency, give it a spin. The free plan lets you try the core flows, and the cloud version handles the heavy lifting on the AI side.

All the best,
