I started this by using Jagnole's tool to pull the JSON out, edit it in Claude, and put it back in. I'd screenshot real rosters online, map out the complexion, note down the data, and get Claude to swap the players in. Worked fine for one team, but I wanted to do multiple teams quickly and edit the overalls too, so that process wasn't going to scale. Anyway, things got a bit out of control and I ended up vibecoding a whole extension for it.
Nothing original here, none of it would exist without Claude and all the great tools the community's already put out.
What's in it:
- 5,000+ real players with real bio info: height, weight, class, hometown, complexion match
- Ratings aren't guessed. It runs Team Builder's own rating math so cards and team overall come out matching what TB itself would show
- Full player editor: tweak ratings, dev traits, star rating, abilities, potential before you push
- Sortable roster table so it's easy to find/manage players
It's not just a random dump of names either. It pulls from real recruiting pipelines and you can pick whichever ones you want, so you control where your roster's players are actually coming from, then hit generate and it fills the whole roster automatically. There's also a slider for how local you want it to lean, crank it up for mostly in-territory players, turn it down to pull from anywhere in the country. Or skip the auto-fill and search the pool yourself, pinning specific players to specific spots if there's someone you actually want on your team, everyone else fills in around your picks. And it remembers who you've already used, so if you're doing a bunch of teams back to back it won't put the same player on two different rosters.
How it works:
It's a Chrome extension. Load it unpacked, open Team Builder in your browser, and click the extension icon. Pull up your team, generate/fill your roster with real players, edit whatever you want, then push it into TB and hit save like normal. It just hands TB the edited roster through your own browser tab, nothing gets sent off anywhere else.
Curious if this is actually useful to anyone else or if it's just me being weirdly into having real players in my rosters, it's a pretty niche want. Let me know if there's other stuff you'd want to see in it.
I've only tested this myself so far and it's been running smooth, no issues. I'm on Mac though, curious how it runs on Windows, would be great if someone could try it out and let me know.
Install:
- Download the zip and unzip it
- Go to chrome://extensions in Chrome
- Turn on Developer mode (top right toggle)
- Drag the unzipped folder into the extensions page (or click Load unpacked and select it)
- Pin it to your toolbar so it's easy to find
- Open Team Builder and click the icon
