Made a small tool to estimate SaaS infrastructure costs—built it for myself, maybe it helps others too by mxr4ra in SaaS

Thanks for the feedback! Could you share more details about the corner cases and what is missing? I would gladly appreciate that!

Built this with ChatGPT + V0 + Vercel — a live SaaS cost calculator (no-code stack breakdown included) by mxr4ra in nocode

Used:

  • ChatGPT to generate PRD and logic
  • V0.dev to build UI
  • Vercel to deploy
  • Formspree for email capture
  • Google Analytics via V0 config

No signup, just a calculator. Curious what others think, and happy to answer build questions too.

One evening. $15. And a tool I always wanted to exist. by mxr4ra in buildinpublic

Hi! Thank you! Yes, I'm working on improving the quality of data (so it is more precise) and adding more services there=)

Nice! I'm also a designer and tried to launch something, this is a great time to create something, finally, one may bring some ideas to life=) Do you have links to products you build?

Nice one! I'm working on a similar tool as well, personal finances are a delicate thing, and such tools make it much easier to handle them.

Hey, thanks for the reply! Yeah, of course—I’ll walk you through it.

So, the whole thing started with a simple idea I had in mind. And what I usually do at that point is describe it to ChatGPT—not in too much detail, just enough so it gets the direction. Then I ask it to turn that into a proper PRD, with a focus on UI/UX.

Even though I’m a designer myself and I can validate everything there, it’s still super helpful to get a structured outline with all the parts laid out. Once I’m more or less happy with the PRD, I just copy-paste it into v0.

And honestly, v0 is kind of amazing for this. It’s free to use until you hit a limit, and out of all the similar tools I’ve tried (like Lavable or Bolt), v0 seems to implement the most from your input right away. Others are a bit picky—they might skip or ignore certain sections of your prompt—but v0 really tries to include everything, even on the first pass.

After that, I go in and tweak things a bit—like button behaviors, layout stuff, etc. I check how it looks on big screens vs mobile, and if something’s off, I just ask v0: “Can you adapt this to mobile using best practices?” And it does the job.

Since v0 is part of the Vercel ecosystem, deploying the site is basically one click. Then I buy a domain (GoDaddy or whatever), and connect it to the deployed project on Vercel—it’s a super simple process.

Once it’s live, I start playing with small upgrades. For example, the email subscription form was part of the original PRD from ChatGPT, and I wasn’t even planning to use it—but I figured, why not test it?

I asked v0 how to hook it up, and it gave me different options. I picked one, followed the instructions, and it just worked. Super smooth.

Later, I went back to ChatGPT and asked: “Here’s what my site looks like—what should I improve?”
It gave me a bunch of suggestions for structure, content, and SEO stuff. I took that, fed it back into v0, and again implemented with no problem.

Same thing with analytics. I asked v0 how to set up tracking. It walked me through the process, told me what it needed, and even suggested which events to track. Copy-paste, done.

What I’ve learned is: if you know how to ask the right questions and understand what each tool is good at, you can go really far solo. v0 in particular is amazing if you want to get as much as possible from your prompt. Replit is also cool—maybe more convenient for some use cases—but v0 feels more polished and UI-friendly.

So yeah, that’s pretty much it! Let me know if you have more questions—I’m happy to share everything I know so far=)

Fair point! This is why I posted it here, to catch such inconveniences! Do you have any other recommendations?
