Brag: Turn Any Project Into a Launch Video With One Command

Building the thing is only half the job. The other half is showing people, and making a good launch video usually means hours of editing, music hunting and second-guessing.

Brag does it with one command. It's one of my favourite repositories right now, and I've already used it for two of my own products. Big recommendation from me: go check it out.

#What Brag is

Brag is an open-source agent skill from latent-spaces. In their own words: "You built it. Now brag." You run it inside a project you've finished, and it turns that project into a short, shareable launch video, with music, motion and ready-to-post share copy.

At the time of writing it has about 20.9k stars on GitHub, and it's MIT-licensed.

#How it works

1. It studies your project. Brag works out the product angle, the tone and the key moments worth showing.
2. It writes a brief. It turns all of that into a focused brief for Hyperframes, which builds, times and renders the video.
3. You get the files. Everything lands in a brag-output/ folder: the plan, the brief, your share copy and the finished brag.mp4.

You can steer it too:

• --tone "..." changes the mood, for example something playful or satirical.
• --voice adds an optional narration.

#Videos I made with Brag

Here are two launch videos I made with Brag for my own products.

Ring Ping, the reminder app that calls you:

Rank Kiwi, the Chrome extension that finds viral outlier content:

Each one started as a single command in the project folder. That's the magic: the gap between "it works" and "people can see it works" gets tiny.

#How to install it

In Claude Code:

/plugin marketplace add latent-spaces/brag
/plugin install brag@brag

In Codex:

codex plugin marketplace add latent-spaces/brag
codex plugin add brag@brag

In other agents that support Agent Skills:

npx skills add https://github.com/latent-spaces/brag --skill brag

Then open your project and ask your agent: "let's /brag".

You'll need Node.js 22+, FFmpeg on your PATH and the Hyperframes CLI (npx hyperframes). If you'd rather skip the setup, letsbrag.app can make one from just a link to your site.

#Why I like it so much

• It removes the excuse. "I'll make a launch video later" usually means never. Now it takes minutes.
• It understands the product. It doesn't just glue screenshots together. It works out what's interesting about your project.
• It's open source. You can read how it works, change it and make it yours.

If you build side projects, give Brag a star on GitHub and try it on the next thing you ship. Then come tell me what you made.
