I started working with Claude Code in Firebase Studio today, and honestly, it’s a game changer. Tasks that used to feel clunky or required lots of trial and error in the prototyper now flow effortlessly with Claude Code. It handles complexity with ease and really speeds up the whole process.
If you haven’t tried it yet, I highly recommend giving it a spin. It’s definitely worth exploring.
Would like to hear a couple of examples from your experience if those are still fresh in your memory please!
How exactly did. you connect Claude and firebase studio?
Interesting. How did you set it up?
My web app has gotten pretty big with a bunch of features and 50+ Cloud Functions. After a while, the Prototyper turned out to be kind of buggy and struggled with the more complex stuff I needed. Switching to Claude (mostly the Opus model) was a big step up and way more accurate, especially for larger refactors.
The Prototyper is fine to get started, but I really hope Google keeps polishing it, because Firebase Studio and the whole Firebase ecosystem are already great.
@Xanax_king: Just made an Anthropic account, installed Claude through the terminal, added the extension… all done in about five to ten minutes.
I am using the same concept. But not Claude code. But using the built in Gemini CLI. It’s super powerful and for design and aesthetics changes I rely on Firebase studio prototyper and for core features I use Gemini cli in Firebase studio terminal.
You talk about a larger app, what sort of cost is Firebase costing you on Blaze plan? I received a $307 monthly bill which seems extremely high IMHO.
If you dont mind me asking - what is the cost and much is Claude costing you on top of Firebase?
It’s important that these tools be cost effective otherwise they are fir the dust bin.
Kind regards
Jono
Since I don’t have any users yet and am still in development, my costs for the Firebase ecosystem are $0. However, I pay Claude Code a fixed amount of $200 for the max plan.
As I can see from your other posts, you’re using Gemini 2.5 Pro. I’ve heard several times that costs can quickly skyrocket with that. It’s strange, though, that you set the budget at $25 but weren’t informed.
Yes I will follow up with Google to try to understand how my set budget could be ignored.
Jono
I have followed up with Google billing and sorted out my bill.
As it turns out when you set a budget you are not really setting a budget.
Their is no way to limit the spend. In short Googles current set up seems like a large con-job. You set up Blaze and then you can spend well over your budget limit and then face a large bill.
I just don’t know why Google is set up like this, other than follow the money. Any other business (like a telco) allows users to set a budget and its a budget. Not with Google. They missed the mark on customer focus when it comes this.
Also for your and other folks information -
From myself - ok which gemini models are you using?
From Gemini
Of course. Based on the current project files, here is a summary of the Gemini models being used for different tasks:
For Text and Narrative Generation:
gemini-1.5-pro.For Image Generation:
googleai/gemini-2.0-flash-preview-image-generation.In summary, the project relies on gemini-1.5-pro for its text-based reasoning and generation, and googleai/gemini-2.0-flash-preview-image-generation for its visual generation capabilities.
Could you give me an idea of the costs involved in Gemini CLI please.
How do you do this integration? Claude X Studio Firebase?
Go to the Extensions tab, search for Claude Code, and install it. Then, install Claude Code via the terminal. You can find instructions on the official Anthropic website.
Cool! Thanks for sharing! How about the limits of Claude Code? I’m thinking which plan should I go to. Since gemini is free. ANd its like unlimited of usage for me. I’m still in the early stage of learning. Though I’ve already deployed and sold some small projects. 
Gemini CLI is having a big generous free quota. So i don’t think you need to worry about the cost initially
Ok how do i connect it all up?
Isn’t it run in some form of terminal on your desktop? So how do I connect it to Firebase?
Thanks mate, been having issues with the prototyper, Claude fixed it in minutes
You find some infos about limits here: Using Claude Code with your Pro or Max plan | Anthropic Help Center
I think the $20 plan is sufficient for testing claude at the beginning. If you like it, you can always upgrade.
Nice!! You are welcome
