RedLineCAD didn't start as a public product. It started as a personal project — built quietly in the background while Leonida Department of Justice was still being put together. LDOJ is a GTA VI roleplay community still in development, and the thinking was simple: a community with its own CAD has its own identity. Off-the-shelf tools couldn't give that. So building from scratch was the only option.
Back then, it wasn't even called RedLineCAD. The original name was NexusCAD — a name that's still being reserved, just not for GTA. More on that in a moment.
The backgroundThis wasn't built by someone who discovered roleplay last year. 12 to 13 years of roleplaying. Over a decade specifically in GTA. Community member, department head, command staff — including a stint as Assistant Chief of the LSPD inside Imagination Station RP, one of the more serious communities in the space. That kind of time across those kinds of roles teaches you exactly what works, what gets ignored, and what makes a server feel like a real place versus just a game lobby. Sitting in command, running a department, managing officers mid-session — that's where you learn what a CAD actually needs to do under pressure. A good CAD is one of those things that quietly holds everything together — and a bad one is felt by every single member, every single session.
The shift happened on a PS5. Playing in RedwoodRP, the thought hit — what was being built for LDOJ was good enough to share with everyone. Not just one community. Every community.
That's when NexusCAD became RedLineCAD, and a private internal tool became an open-source project available to any GTA V or GTA VI roleplay server on the planet, for free, with no strings attached.
NexusCAD starts as a private build for Leonida Department of Justice — a GTA VI RP community still in development.
Playing RedwoodRP on PS5 sparks the idea to open it up. NexusCAD becomes RedLineCAD. The public version is born.
Claude AI integration was never part of the original plan. Then it was — and it changed everything.
182 JS files. 300+ features. 17 AI-powered tools. Zero cost. Used by GTA V and GTA VI RP communities worldwide.
NexusCAD — the name being reserved for real-world deployment. Security, police, fire, EMS. The GTA version was always the foundation.
AI was never meant to be part of the CAD. But am I glad it is? Hell ya.
— Brandon, creator of RedLineCADThe interrogation room. The medical diagnosis assistant. The training simulator. The radio chatter that makes an empty server feel alive. None of it was in the original plan — and all of it ended up being some of the most important features in the whole build. Sometimes the best parts of a project are the ones you didn't see coming.
Why it's freeRedLineCAD was always going to be free. Not free-with-a-catch, not free-until-it-gets-popular — just free. There's a donate button, but that exists for one reason:
To keep the CAD alive and not self-destruct.
— BrandonNo subscription tiers. No feature walls. No "upgrade to unlock." Every single feature — all 300+ of them — is available to every server, from day one, forever. That's the whole point.
What comes nextThe name NexusCAD was set aside for a reason. The long-term vision goes beyond GTA roleplay — into real-world deployment for security teams, law enforcement, fire departments, and EMS. RedLineCAD is the proving ground. Everything being built here is being built with that future in mind.
LDOJ — Leonida Department of Justice — is still being built too. The community this all started for hasn't launched yet. When it does, it'll run on the CAD that was built for it.
Built with people in the cornerNone of this gets built in isolation.
Some people just show up, and that matters.
A few people inside Imagination Station RP deserve to be named. Not for what they built — but for being present while this was being built. Through the long sessions, the bug reports, the feature debates, and the moments where the whole thing looked like it wasn't going to come together — these three were there.
The kind of leader who makes you want to build something worth using. Having the Chief in your corner means something. But beyond that — Podders is the brain behind a majority of the ideas that got expanded into this CAD. The conversations, the suggestions, the vision for what a proper RP department actually needs — a lot of what you see built in here started with him bringing it up.
Great guy to be around — but just like in RP, you have to know someone before you know how to deal with them. Stewie has tested just about every limit there is when it comes to pushing buttons. And honestly? Grateful for it. That kind of energy keeps you sharp, keeps you honest, and reminds you why you're building something worth arguing about.
Iron joined the same day — started at the bottom, brand new to roleplay entirely. Two people, same community, same starting point, opposite ends of the spectrum. Watching someone discover from zero what you've known for over a decade has a way of showing you things about your own experience you'd stopped noticing.
