i'm a developer not a founder. built RivalIntel because i kept seeing people on reddit complain about missing competitor pricing changes. everyone says they check manually but nobody actually keeps it up.

you add competitor urls, it scrapes them every night, and if something real changed it emails you what changed and why it might matter. tries to filter out cookie banners and layout junk so you're not getting spammed.

been marketing for 3 days. posted on reddit twitter linkedin. got about 13 real comments on one thread. talked to someone who built a similar thing for retail pricing and learned more from that than any paid lead gen tool i tried.

also fixed the landing page yesterday. before that ''rivalintel dot xyz'' just dumped you into login. probably lost everyone who clicked.

free right now. 2 competitors, 5 urls.

if you want to see what an alert actually looks like without waiting overnight there's a demo page that fakes a price change every 60 seconds.

''rivalintel dot xyz''
Because of rule i am typing like this

try it and tell me what would make you pay for it. or tell me it's useless. both help. i'll reply to everything.

I kept running into the same thing when writing tests.

Need a quick mockUser, mockOrder, mockProduct, etc.

Most of the time I'd either hand-write it, copy an old fixture, or spend more time setting up mock data than writing the actual test.

So over the last few days I built a small tool called FixtureKit.

You paste a TypeScript interface or Zod schema and it generates a ready-to-use fixture object.

Example:

interface User {
  id: string
  name: string
  email: string
  role: "admin" | "viewer"
}

becomes:

export const mockUser: User = {
  id: "...",
  name: "Alice Johnson",
  email: "alice@example.com",
  role: "admin",
}

A couple things I cared about:

• Works entirely in the browser
• Doesn't need Faker setup
• Handles nested objects, arrays, unions, and optional fields
• Generates realistic values based on field names
• Deterministic output so the same schema always generates the same fixture

Still early and I'm sure there are TypeScript/Zod patterns I haven't thought about.

What are you all using for fixture generation these days?

genuine question because i see this come up a lot.

when a competitor quietly changes their pricing, adds a new tier, or repositions their features .. how do you actually find out? what's your real process?

from what i've seen most people are either:

- manually checking every few weeks (and forgetting)

- using google alerts which misses page-level changes

- finding out from a customer on a sales call

curious what actually works for solo founders or small teams without a dedicated PMM. is there a system that doesn't require remembering to check?

solo dev here. noticed a pattern where founders keep saying the same thing , they find out a competitor changed their pricing or launched a new feature when a customer mentions it on a call. by then it's already too late.

so i built a tool to fix that. you add competitor URLs (pricing page, features page, changelog), it scrapes them every night, and if something real changed it emails you a plain english summary of what changed and why it might matter. not just "something changed on this page" , actual context about the move.

the hard part was noise. pages change constantly for stupid reasons ,cookie popups, ad rotations, layout tweaks. spent most of the time filtering that out so it only fires when content actually changes.

it's called RivalIntel. live at rivalintel.xyz, free to try.

curious if this is actually a problem people here deal with or if i'm solving something that isn't painful enough to matter

solo dev here. built this because i kept seeing founders complain about missing competitor moves and thought it was a solvable problem.

the idea is simple: you add competitor URLs you want to watch (pricing page, features page, changelog), it scrapes them every night, and if something meaningful changed it sends you an email explaining what changed and why it might matter. not just "something changed" — actual context.

the annoying part to build was the noise filtering. pages change constantly — cookie banners, ads rotating, layout shifts. had to tune it to only fire when real content changes, not html junk.

also built a demo page that auto-increments a price every 60 seconds so you can actually see the AI alert fire in real time without waiting overnight.

live at rivalintel.xyz — free, no card needed.

curious if this scratches an itch for anyone here or if the problem isn't painful enough to matter.

Built this over the last few days after getting tired of hand-writing mock data for tests and Storybook.

FixtureKit lets you paste:

- TypeScript interfaces

- Zod schemas

and generates realistic fixture objects instantly.

A few things I focused on:

- deterministic output

- browser-only (nothing leaves your machine)

- no eval

- works with nested objects, arrays, unions and optional fields

I'm mainly looking for feedback from people using Next.js + Zod.

What schema shapes would break this in your codebase?
