Why do Rockstar’s games feel so far ahead of everyone else’s? According to an ex-Rockstar developer, Antonia Landi, the answer isn’t what most people expect. It’s not about budgets, star talent or even the RAGE engine. Instead, it comes down to the tools the studio builds for itself.
Who is the ex-Rockstar developer?
The developer worked at Rockstar North between 2014 and 2015. That was a huge period for the studio. During her time there, Rockstar released GTA Online Heists and brought GTA 5 to PC and what were then next-gen consoles.
In a viral video, she shows off photos from the GTA 5 launch party and her name in the game’s credits. She even reveals the tattoo she gives all her GTA Online characters.
The secret nobody talks about
She says people love hearing about her time at Rockstar. However, one topic never comes up: internal tooling.
Most fans know about RAGE, the engine behind Rockstar’s games. What they don’t realise is that most of Rockstar’s development and QA tools were built in-house, and still are today. These tools help teams create, test and fix the games.
Why the ex-Rockstar developer says tooling matters
She has worked at three companies that tried building their own internal tools. Even so, she says Rockstar is still the only one that “had it figured out.”
The reason is simple. Rockstar took tooling seriously. According to her, entire development teams existed just to improve and maintain the tools the whole company relied on. In other words, it wasn’t a side task for anyone. It was their main job.
That approach fits Rockstar’s reputation as a famously secretive and self-reliant studio. Rather than relying on outside software, it builds what it needs and keeps refining it.
Built in-house, not bought in
At Rockstar, tools weren’t something you simply bought. They also weren’t seen as a way to save a bit of time. Instead, she calls them “foundational.”
She also pushes back on a popular idea. With AI coding tools now widely available, many companies believe they can build their own version of Jira or Slack. She admits AI has levelled the playing field. However, she warns that companies will “fail hard” unless they commit the same time and resources to developing and maintaining those tools long term.
Advice from an ex-Rockstar developer
Her verdict on Rockstar is clear. “Rockstar thrives because they are relentless in every single thing they do,” she says. “There are no compromises.”
She also has a message for developers at other studios. If you wish you worked somewhere like Rockstar, she suggests thinking about what it would take to raise the bar at your own company. She admits she might be biased, but she would start with internal tools.
What it means for GTA 6
Her comments offer a rare look at how Rockstar works behind the scenes. They also help explain the incredible detail fans have come to expect. From reactive NPCs to complex weather, those systems need powerful tools to build and test.
That matters more than ever now. GTA 6 launches on November 19, and it’s set to be Rockstar’s most ambitious game yet. If this ex-developer is right, the tools behind the scenes are a big part of why Leonida could feel so alive.
