I work a day job and vibe code at night. Here’s what broke in my first month building an astrology platform.
I’m new to building. I work a regular day job, then spend my evenings vibe coding with AI agents.
For the past month, I’ve been building mysticos.ai, mostly on my own.
Part of the reason was personal. Life had started to feel repetitive and, honestly, a little boring. This project gave me something I genuinely wanted to keep thinking about and improving. That has probably mattered more to me than any of the numbers below.
The product compares readings from 10 astrology and divination systems. Instead of blending them into one vague answer, it shows where the traditions agree and where they contradict each other.
After one month:
- 761 generated pages across 11 locales
- Deterministic chart calculations in a separate service; the LLM interprets the results but never generates the underlying numbers
- Coding agents wrote roughly 95% of the code. I described what I wanted, reviewed the output, tested it and made the product decisions
A few things that broke:
- A login bug only appeared when someone clicked Submit very quickly. It was a hydration race that caused the browser to reload the page and wipe the form.
- Missing translations silently fell back to English. I shipped partially translated German and Turkish pages without noticing.
- A refactor removed three of four Vedic charts while every test and build still passed. I caught it only by manually comparing screenshots.
- A calendar date appeared one month early for some US users, and a Chinese romanization collision turned one “wu” into “woo” in the English UI.
The main lesson: AI agents make it easy to produce code quickly, but they don’t know whether the product is actually correct unless you build the checks yourself.
I’d really appreciate it if anyone here wanted to take a look. In particular:
- Does the “different traditions can disagree” idea sound interesting or confusing?
- What part of the product feels unclear or difficult to trust?
I read the subreddit rules before posting and tried to focus on the process, what broke and what I learned—not just drop a link. Hopefully this fits :)
