Bloom: AI Social Media Studio (Full Source Code)

Bloom is a full AI social media studio, built to plan a month of content in the time it normally takes to plan a day.

Give it a topic and a platform and Bloom writes a ready-to-publish caption, hashtags, and a matching cover graphic in seconds, in your brand voice.

Name a goal and Bloom drafts a whole slate of on-theme campaign post ideas you can turn into scheduled posts with one click.

There's a full content calendar: schedule posts across the month and see your whole plan at a glance.

Every post gets an automatically generated cover graphic in your brand color and mark, no separate design tool required.

Set your brand voice once during setup and every generated caption, on every platform, stays on-tone from there.

Bring your own key: connect Gemini or Claude with your own API key from Settings. No key yet? Bloom still runs on a built-in test engine so you can try everything without one.

Comes seeded with a demo workspace (Aurora Coffee Co.) so you can explore a populated account right away instead of starting from a blank slate.

Built on Node.js with zero external dependencies, just node:http, node:sqlite, node:crypto, and node:zlib from the standard library. No npm install, no build step, no bundler. Requires Node.js 22.5 or newer. A live demo is included so you can try the full flow before you buy.

Requirements

Node.js 22.5 or newer. No other runtime dependencies.

Compatibility

Linux, macOS, Windows. Any host that can run Node.js.
