Google launches AntiGravity AI coding tool that can work like junior developers, raising fears of job loss
Along with Gemini 3, Google has also launched Antigravity. It’s a new coding tool and it raises new questions about the future role of junior developers.
It seems that one area that tech companies believe is ripe for disruption is coding and software development. Companies like Google and OpenAI are increasingly focusing on this. So, when Google launched the Gemini 3 AI system last night, it also announced AntiGravity, a new coding tool that uses AI for software development work. Interestingly, the company is projecting this as the beginning of a different kind of coding era, where AI doesn’t just assist, but actively works with developers.
This announcement came alongside the Gemini 3 Pro, and together they form the core of what Google calls agent-first software development.
At first glance, AntiGravity feels like a step forward from typical AI autocomplete or chat-based coding assistants. It’s built to run multiple AI agents at the same time, letting them work directly inside your code editor and browser, and even allowing them to plan, execute, and cross-check their own coding work. Instead of asking the AI to fix a line or generate a function, the idea here is to give it an entire task and see if it does the heavy lifting.
In its blog post, Google suggested that AntiGravity tries to behave more like a coworker than a chatbot. “As model intelligence accelerates with Gemini 3, we have the opportunity to reimagine the entire developer experience. Using Gemini 3’s advanced reasoning, tool usage, and agentic coding capabilities, Google AntiGravity transforms AI assistance from a tool in a developer’s toolkit to an active partner.”
How antigravity works in simple words
The platform provides AI agents with direct access to code editors, terminals, and even browsers. So if you ask it to build a basic web app, it will not only generate code but also run tests, debug problems, open your browser, verify the output and then give you the results ready for review. In Google’s demo, it also built a small flight-tracking app and produced a browser recording of a test run.
To help developers understand what the AI is doing, AntiGravity generates what Google calls artifacts, things like plans, screenshots, task lists, and recordings. Instead of scrolling through dense activity logs, you get clear checkpoints of the work the agent is doing.
Obviously, there are two ways to use it. One is the editor view, which looks like a normal coding IDE with an AI assistant on the side. The second is Manager View, which is aimed at people who want to run multiple agents at once, almost monitoring multiple virtual interns working on different parts of a project.
Google also says that agents will “learn from previous work,” meaning they can save relevant code snippets or workflows and reuse them later.
AntiGravity is now in public preview on Windows, macOS, and Linux. It’s free and Google claims it has a “generous rate limit”, refreshed every 5 hours. It also works with models beyond Gemini, including Cloud Sonnet 4.5 and OpenAI’s GPT-OSS.
But will it replace junior developers?
This is the part many people may be wondering about, and the honest answer is more nuanced than yes or no.
AntiGravity clearly has the ability to perform tasks that are often assigned to entry-level developers, including boilerplate coding, browser testing, setting up basic projects, running checks, cleaning files, etc. In regular workflows, this can reduce the need for juniors to perform frequent support tasks. But, one also needs to understand that junior developers do not just write code. They learn how systems work, develop a plan, understand business logic and grow into senior roles.
AI can automate tasks, but will likely still need humans to define goals, review outputs, catch subtle bugs, and guide architecture-level decisions. Therefore, companies still need developers who understand what’s going on under the hood because AI can confidently make mistakes.
However, Antigravity really has the potential to change how Junior begins his journey. Rather than starting with simpler tasks, understanding and supervising an AI-powered workflow may require more. This may raise the bar, not eliminate the situation entirely. And for many teams, tools like AntiGravity will likely become productivity enhancers rather than replacements, at least for now.
