The math that changed my mind
Two quotes. Six weeks and $15,000 from a freelance dev. Or 8 hours of my own time and $20/month with Mythex. I chose the second option, and this is the exact breakdown — plus the template I used so you can justify building in-house, too.
I run a small SaaS. Customers kept emailing me for invoices, usage stats, and password resets. I needed a portal. The old me would have hired it out. The new me opened a browser tab.
The freelance quote
I got two quotes from freelancers. Both landed around $15,000 and 6 weeks. That included:
- A simple login system
- A dashboard showing account usage
- Invoice downloads
- A settings page
- Basic styling
Nothing crazy. But by the time you add revisions, meetings, and handoff, you're at six weeks and a five-figure invoice. For a bootstrapped founder, that's brutal.
The Mythex path
I built the same thing myself. Not from scratch — by describing it in plain English and letting the AI app builder handle the code.
Here's what I did:
- Went to mythex.ai and described the portal in my chat prompt.
- The app scaffolded a working React + TypeScript app with a live preview.
- I iterated by chatting: "Add a login page," "Show usage stats as charts," "Let users download invoices."
- I attached a couple of sample invoice PDFs to test downloads.
- When it looked right, I published it to a real URL.
Total time: about 8 hours, spread over a few evenings. Most of that was my decisions — copy, colors, which charts mattered.
The exact cost breakdown
Here's the honest ledger:
| Item | Freelance | Mythex |
|---|---|---|
| Time | 6 weeks (waiting) | 8 hours (focused) |
| Cost | $15,000 | $20/month (Pro plan) |
| Control | Limited to scope | Full edit anytime |
| Iteration | Slow, expensive | Instant, cheap |
Hosting: The published app runs on Mythex's infrastructure using runtime credits. My $20/month Pro plan includes credits that cover both building and hosting for a small portal like mine. No separate server bill.
Database: I needed a small database for user accounts. Mythex attaches one with a few clicks. Usage comes out of the same credit pool.
Total monthly bill: $20. And that includes the AI model, hosting, and database — not just the build.
Why the ROI is so lopsided
The numbers only tell half the story. The real advantage is iteration speed.
With a freelancer, every change was a new quote and a new wait. With Mythex, I just type: "Move the invoice button to the top," and it's done in seconds. I've made a dozen tweaks since launch that would have cost me another $2,000 freelance.
Also, I own the code. Mythex gives you a real workspace — files, terminal, git export. If I ever need to leave, I can take everything with me.
The template I used
Here's the exact prompt template I started with. Feel free to copy it.
Build a customer portal web app. Features:
- Login with email/password
- Dashboard showing account usage (chart + table)
- Invoices page: list + download PDF
- Settings page: change email, password
- Clean, modern design (Tailwind)
- Mobile responsive
Then I iterated with follow-ups:
- "Add a welcome email after signup."
- "Show a 'Last billed' field on the dashboard."
- "Style the invoice list as cards."
That's it. No technical expertise required.
How you can justify building in-house
If you're a bootstrapper considering a similar project, here's how to make the case:
- List the features you actually need — not the ones you think you need.
- Time-box it. Give yourself 2 weeks max. With Mythex, most portals take under 10 hours.
- Compare real quotes — get at least one freelance estimate and put it on paper.
- Account for iteration. Every future change is now free (in time and money).
That last point is the kicker. A $15,000 build might cost you another $5,000 over a year in tweaks. My $20/month plan covers unlimited changes.
What I'd do differently
If I did it again, I'd:
- Spend 30 extra minutes on the initial prompt to avoid rework (adding clear "login" and "logout" flows early).
- Use the Plan mode in chat to talk through structure before building.
- Attach brand assets (logo, colors) from the start so the AI styles everything consistently.
Your turn
If you're a solo founder staring at a six-week quote, you have another option. Mythex turns plain language into a working web app — and you keep full ownership.
Eight hours and $20/month changed my business. It can change yours.
This is a personal ROI case study. Your results may vary based on scope and complexity.
