Here's my short review after playing around with Firebase Studio for ~30 minutes. First of all, I had to turn off Firefox Enhanced Tracking Protection because otherwise projects wouldn't load.
I gave it the following initial prompt:
> An app where you input a question, then flip some coins to generate an I Ching prediction, and it generates a prediction / fortune for you. Then this combination of results can be fed to Gemini AI to produce a more detailed prediction text.
It generated something that looked fine. When I input a question and press the button nothing happened. After asking it to fix the problem multiple times and having it fail, I looked at the browser console to figure out the errors it was getting. Then I copied those errors and told it to fix them. After a few iterations, it solved every error and would generate a result. It completely forgot the part where you are supposed to flip coins before getting a hexagram to generate a fortune. After a bit of prompting, I was able to get it to display the hexagram and input question. However, sometimes it becomes confused about which hexagram was generated.
Overall, my impression is that these tools are still in the toy novelty stage rather than something you'd want to use for anything important.
Here is a screenshot of the app output for the question: Will Hacker News like my vibe coded oracle? [0] As you can see, it says that the generated hexagram is 24 or 41, but in the fortune text below it says 11.
I built a complete working application (errortexts.com) using an AI tool, so I have a little insight on this.
At first, the product I was using (lovable.dev) seemed to me exactly as you described. I gave it a basic app outline and hit run, and it produced something that superficially looked right but did nothing.
So I asked some other people for advice, and they said you have to hold its hand and go step by step. So I did.
I told it, give me a landing page that matches [product description], but implement nothing else. Then, ok, let's set up auth - add a sign in and sign up dialog. Then, ok, let's create a user account page. Bit by bit.
It succeeded wildly. I was able to build the whole thing in 3 days. I'm not capable of that on my own, it would have taken me 3 weeks. Sometimes the AI got stuck and I had to manually go in and accomplish what I wanted. It took over 100 steps to complete the product, and probably around 10-20 times I had to revert its changes and give it more specific instructions. I had to check its work at every iteration, just like with a junior developer.
But it worked. And it's going to get better. Would I use this for "something important"? Depends how you define that. I used it to build a working product. Would I start letting it modify an existing mature codebase willy-nilly? No, probably not. Would I let it write cryptographic logic or trust that it wrote bulletproof code from a security standpoint in a sensitive context? No.
But for a simple application, it was an incredibly powerful tool. Especially for something that didn't even exist just 2 years ago. Give this a decade and it's going to change all our careers even more than it already has.
Can you... provide the prompts? Because I have a hard time believing this.
I have tried the hand holding approach with Cursor. It doesn't work for me. I have to constantly correct and over correct. Getting auth working sounds insane to me.
With these tools you have to talk to them as if you were talking to a knowledgeable, but a bit clueless junior developer. Sometimes it's almost as if you were coding it, just without typing the code.
I put your prompt into the vibe coding tool I'm working on (shameless plug).
The first version[0] looked good, but when I inspected it I found that it just picked an I Ching prediction at random on the back-end, instead of actually flipping coins.
I updated the prompt to the following:
> Create app where you input a question, then flip coins to generate an I Ching prediction (client-side). First show the standard I Ching prediction and it's hexagram, and then use AI to generate a fortune analysis based on the prediction and your initial question.
And the result was much more laborious[1] of a UI :shrug:
The ai part of the app is basically useless. After 2 hours of “vibe coding” a chess clock flutter app I got basically nothing in the end.
It broke more and more each message. I tried fixing stuff myself but it would mess it up again.
Would not recommend anyone to use it.
Now for the non ai part: super cool. I love the nix environment. Its fascinating how they handle the previews for example. I got geekbench up and running an the cpu is a bit worse than an iphone 15 pro max, but it has 32 gigs of ram!
The app prototyping logic in Firebase Studio isn't wired up for Flutter/Dart yet. You can play with Gemini+Dart/Flutter here: https://dartpad.dev/?channel=main.
We're working with the Firebase Studio team to integrate. FWIW, it seems to do fairly well with "Create a chess clock app".
Hey. That makes more sense. To be honest, I don’t think it should be one of the main things on the front page when creating a new project in that case.
However for what it’s worth Ive also asked gemini to translate this simple chess clock app to react because of how buggy the flutter project was and it just got stuck again and again no matter how much I helped it
After everything initializes and your Android and web previews set up, open chat by clicking the little Gemini spark at the bottom of the workspace and then add your prompt.
YMMV, but I got a very basic, but working chess clock in one shot with "Can you replace this sample Flutter project with a fully-functional chess clock that works on Android and on the web?"
That's how I've done it when it did not work. I did, however, go easier, one by one. I first made a simple countdown. Then I made it count down from 10 minutes to 0. Then I created 2 of them. Then I put them side by side. Then I did the logic, one counterstarting each other. Every step of the way, it was filled with loads of errors and loops out of which the ai couldnt get out, to the point where I would need to go there and fix it myself. Errors ranged from logical, to super simple syntax issues, such as missing colons, or brackets.
I have tried again step by step with what you said here, copy pasted the prompt even and after a couple changes here and there it loses the plot and gets stuck and seemingly no amount of prompting can get it out.
To make sure I tried 3 times in a row. Same result.
As a person currently working on a project that uses Firestore (the db component of Firebase), there is one thing - and only one thing - I want.
A web GUI for Firestore that lets me work on documents like, idk, any other DBMS GUI would: the ability to select multiple records, and operate on them.
That's literally it. I don't need AI, I don't need dark mode, I don't even need MongoDB compatibility. I just want to select multiple documents with my mouse and do things to them.
"Now that you've been promoted, you don't build CRUD tools anymore. Those are below your level. Instead, you build AI agents that build the CRUD tools."
For me the biggest missing block is the text search API. It's ridiculous that you can't add a basic search input to your Firebase-based website unless you use TypeSense, Algolia or some other additional database that you have to manage and keep in sync.
Despite all the recent enshitification, I can't think of any alternative solution that would come even close to what Firebase has to offer. Authentication API is especially hard to beat (cheap and very easy to integrate).
Looking at that, I'm not sure corporate would be down for something like that as a solution for "select multiple documents in a database GUI and operate upon them". Could be wrong though.
First off, this looks really cool and I'm excited to see more things like this.
The overall chat in the HN conversation has got me thinking, though.
Around 7 years ago in my career, one of my most common actions for one-off scripts was for me to create a WinForms application with, often, a couple text boxes and a "Run" button of some sort.
The text boxes would be the inputs and the run button would ... run. There was also often like a text output or bunch of loglines or something. I wrote almost exclusively in C# at the time, so it was a way to shove a bunch of C# code into place and test it.
I did this for random and arbitrary things I needed to process or solve, a lot like how I used Python or Ruby in the future.
I bet it's actually pretty common for people to need "a script that does a thing", and I think, maybe, that's where a lot of the AI scripting of the most immediate use is going to be. If it can be a familiar interface for people to build (in the past, the IDE) and a familiar or simple place to interact with the generated script (the WinForms + buttons), these programs to generate scripts and do "stuff" could likely spread pretty wide.
I think Jupyter Notebooks are another example of this, another precursor, of sorts?
That's one use case where LLMs really help me, one-off scripts where I know exactly what I need done, know it's possible but would take me much longer to brush off my Bash, Python, etc. skills to write it. Give the LLM a prompt, let it write the scaffolding, do the tweaks I need, and iterate over with the LLM if I forgot how exactly it was to write a for-loop in Bash.
Software engineers, who are the most skilled in terms of holding ai's hand to create a product, should be cloning every single saas out there and making money by eating a share of the market. AI is a great way for engineers to become founders. Let's bring the competition.
5 years working at startups has taught me that go-to-market is almost always the most important function. There are very few truly novel spaces and apps. You can clone whatever you want, but you'll get nowhere without a solid GTM.
I was excited to try this out because I've had a lot of trouble getting the Supabase integrations to work on Lovable and Bolt.new.
Sorry to say that Firebase Studio did an awful job. It did not successfully build even the first view of the app I asked for. It feels like I'm stepping back to release day of GPT-4.
Am I missing a switch to use the good Gemini 2.5 somewhere? I could tell from their response speed that I was not using a thinking model.
this isn't new.. (edit, well actually they've added the "prompt from scratch" thingy like v0.dev/replit/lovable that idx.dev didn't have before) wasn't really gaining the traction they wanted so decided to rebrand. not a bad idea. I use idx.dev (now firebase.studio) and like it. They may not have a "template" for the exact stack/app type you are working with, but it's pretty easy to just setup a blank workspace and modify the nix.dev file as needed..
Here's a dev.nix file that works for FastHTML, which is a little tricky to get the preview working but using this dev.nix it works out of the box. Would probably work with any Starlette or Uvicorn based app as well (obviously make sure you have requirements.txt in order).
Friend is working on a SaaS startup solo as a non-technical founder. Been building using Replit and Cursor with Claude 3.5 and 3.7 and launched with live customers.
I preface because he's been using AI basically every day to build his SaaS.
tbh i haven't used the agentic/gemini integration hardly at all yet. All i did was add an already completed project just to see how the web ide/preview performed.

```
// It works, but we have no idea how to send an HTTP request in java.
// If you do, send us a nice example to support@errortexts.com.
// You just need to POST JSON with the keys `api_key` and optionally `message`.
```
That's brilliant. But it does make me wonder why the LLM couldn't have provided you a suitable Java code example?

Come up with your data model, explain it to the AI, and tell it to give you a CRUD for it.
I'm pretty sure it's perfectly doable to ask it to give you a dynamic crud based on the "shape" of the data in Firestore.
Sadly it's an internal tool for work, so I can't share.
