## Can Google Antigravity really build a working app in minutes for free?

#### Key takeaways

- Google Antigravity installed and produced a working LinkedIn job scraper web app without paying for any tool, needing only a couple of iterations to fix errors.

- The IDE ships with multiple LLMs, including GPT-OSS, Claude Opus 4.5, Claude Sonnet 4.5, and Gemini models, and you can switch mid-project when one hits its quota.

- Antigravity installs without an admin account, so it also works on a school or company computer.

Google Antigravity is a free agent-first IDE, available for macOS, Windows, and Linux, that plans, builds, and debugs an application from a single pasted prompt. In this walkthrough by Ani Björkström, a Stockholm-based tech consultant, it produced a LinkedIn job scraper with a landing page, pricing section, FAQ, and working search, and returned real job listings that linked back to LinkedIn.

### How do you download and install Google Antigravity?

Search for "Google Antigravity download", click the download button, and pick your platform: macOS, Windows, or Linux. On Windows, check whether you need x64 or ARM64 under Settings, System, About; a machine listing "x64-based processor" takes the x64 installer. Installation takes a couple of minutes, requires no admin sign-in, and optionally adds a desktop icon.

### Which conversation mode and model should you use?

Use planning mode for building applications and fast mode only for easy tasks where you want a quick reply. In planning mode the agent first writes a comprehensive implementation plan, then asks clarifying questions, in the demo, whether a database already existed and how search should behave, before building anything. Among the available models, GPT-OSS, Claude Opus 4.5, Claude Sonnet 4.5, and Gemini, the demo started on Claude Opus 4.5, and if you cannot answer a clarifying question, replying "please choose the best option" keeps the agent moving.

| Antigravity feature | What it does |
|---|---|
| Planning mode | Writes an implementation plan and asks clarifying questions before coding |
| Fast mode | Answers easy tasks quickly without a full plan |
| Ctrl+E | Switches to the agent manager |
| Ctrl+L | Opens agent coding or inline code editing |
| Browser preview | Tests the running application inside the IDE |
| Voice input | Lets you speak to the agent instead of typing |

### What happens when the model hits its quota limit?

Mid-build, Antigravity reported "model quota limit exceeded" for Claude Opus 4.5, and the fix was simply switching the model dropdown to Gemini Pro High. The prompt "please fix the issue in the website, right now it is not possible to scrape data" was enough for Gemini to repair the broken search. On the retest, a search for software engineer roles in the USA returned real listings, and "view job posting" opened the actual LinkedIn page.

### Do you need to supervise the agent while it works?

Yes, keep the agent panel visible, because Antigravity asks for permission before harder tasks even when configured to always proceed. The demo agent accepted several changes on its own but still paused for explicit approval before finishing with "application built successfully, dev server running on localhost". Toggling the agent panel away is possible, but the agent is the one doing the job, so it deserves an eye on it.

#### FAQ

**Does Google Antigravity cost anything?**

No tool in the demo was paid for. Antigravity downloaded, installed, and built the entire LinkedIn scraper app for free, including model usage.

**Can I install Antigravity on a work or school computer?**

Yes. The installer does not ask you to sign in with an admin account, so restricted machines can run it.

**Did the app work on the first try?**

Not quite. The first search attempt returned an error, and it took a couple of iterations, including a model switch from Claude Opus 4.5 to Gemini Pro High, to reach a working result.

[0:00] Hi, my name is Annie Burkstrom. I'm a tech consultant based in Stockholm. In this tutorial, I will show you how to download Google's anti-gravity and create a web application step by step. Let's get started. We will open internet browser and we'll search for Google anti-gravity download and then from there we will click on download button and you can see download options for Mac OS, Windows and Linux. In my case I'm using Windows so I will need to download either of those options. And if you don't know if you need to download x64 or ARM 64, you can simply go to settings and from there you can go to systems and from systems go down to about section.

[0:58] Click on about and here you can see system type it says x64 base processor. So this means that you will download this option. It can take couple of seconds to download. Okay, now it is downloaded. So we will click on see more button and then we will open the catalog where the downloaded file is. It is this one. We will double click on the binary file and it will be installed. Here you will say that you accept the agreement and then we'll click on the next button. Next you can decide if you want to create a desktop icon. You can choose this option.

[1:43] Otherwise you can just say next and then install. Now if you are using a school computer or company computer do not worry. Anti-gravity will not ask you to sign in with an admin account. This process can take couple of minutes. So we will come back when it is done. Now it was installed. So we will click on finish button. Now we are inside in anti-gravity and you can see that it looks like a general IDE. On the left side you can see explorer the catalog where your code will be saved. In order to open the explorer, you will click on file and then from there you will go open folder and then you will choose the folder that you want to be opened in anti-gravity.

[2:30] Right to that we have anti-gravity and different keyword selections. For example, Ctrl E that will switch to agent manager or Ctrl L that we can use to code with agent or Ctrl L that is used to edit code in line. On the right side we have the agent chatbot and here you can see that we have two different conversation modes. We have planning mode and we have fast mode. Now you will use fast mode for very easy tasks where you want agent to reply quite quickly. But if you want to develop an application as we will do in that case best is to use planning close to conversational mode. We have different type of LLM models that could be used. And you can see that in here we have chat GPT OSS.

[3:16] Then we have cloud 4.5. Then we have cloud sonet 4.5 and some Gemini models as well. I will recommend to use cloud 4.5 because this is the best model out there right now. In here we will enter our prompt. I have already prepared a prompt using chat GPT. So I will simply go to chat GPT and we copy paste this prompt. If you are interested in this prompt just let me know and I will share it with you as well. Now once I copied the prompt I will go back to anti-gravity and I will pass that prompt. Basically I'm asking anti-gravity to create a LinkedIn scraper and I am specifying exactly how it should look like how login should work and so on.

[4:02] And then I will just click on send button here. Notice that you can even talk. So if you don't want to write, you can just speak with the agent. [snorts] And you can see that it is in the planning mode. Right now it is trying to think about the tasks that we asked it to do. At this point we can explore anti-gravity while it is working. We have the option to customize layout. If you want to choose the layout then we have to build primary site. So if we don't want to see code or code files, we can always click on this button. If we want to see terminal for example, we can click on to Google panel button and that one will pop up. Then we have even the option to toggle agent if we don't want to see agent but that is something that I don't recommend as agent is the one that is doing the job and we need to keep an eye on the agent.

[4:53] Close to that we have search button and then we even have open browser preview and this section we will use when application is already created and we want to test it. Now we can see that agent says I have created a comprehensive implementation plan for LinkedIn job scraper. Before I start building please review and let me know. Also it asks if we have the database or it should configure that one. And then it ask about search behavior. It is important to answer to those questions and we will go ahead and reply to those questions. If you don't know what to answer, you can just write please choose the best option and then we will click on enter button. This is going into thinking mode. So here one more thing that I want to show you.

[5:41] You can see the settings and then under the settings you have themes and then you have color themes and in here you can choose the colors. If you don't like for example dark color, you have different light colors as well. For example, light modern and you have different options to choose. But I personally like dark color. So I will go back to dark modern this one. So the agent will go ahead and accept different task. But when it is a more difficult task, it can ask you for permission. So it is good to keep an eye on anti-gravity. So here you can see that is asking for permission. I will click on permission. You can see that I configured my agent to always proceed. But sometimes it will still come back and ask for permissions. So after accepting couple of changes, I got this notification saying application built successfully.

[6:32] Dev server running on local host. So LinkedIn job scraper was created and the app is now running. Let's click on this local host URL to test it. You can see that the website was created and it looks amazing. So if I scroll up, we can see scrape and analyze job listing. So that's fine. And then we have start searching, upgrade to pro. Underneath that we have how it works. Pricing that is also correct and frequently asked questions. Now let's try to click on those buttons to see if they work or not. Here we can try to enter some values. I think software engineer is fine. USA fine. Date posted we can change to past month. And we can click on search jobs.

[7:17] Here we can see that an error happened. Let's now go back to anti-gravity and ask to fix those issues. And in here it says model quarter limit exceeded. You have reached the limit for cloud. We will choose another model. So you can see that we were using cloud oppus 4.5. So we will change and choose Gemini pro high instead. I wrote to Gemini please fix the issue in the website right now. It is not possible to scrape data. Okay. So based on anti-gravity all the issues are fixed. So let's go and test it one more time. If we click on start search and in here we can choose again software engineer us and everything else can stay as it is. Then we will click on search button and let's see and yes we have actually result in here.

[8:09] You can see the description. We can see a lot of different positions that are working and let's try to click on view job posting and it is taking us to LinkedIn. This is amazing. So what do you think about anti-gravity? Let's remember that we haven't paid for any tool and of course it took us couple of iterations but in the end we have an working solution. So, let me know what you think and if you like this video, please give me thumbs up and have a good
