I Built a Pay-to-Rank Leaderboard Where Products Compete Through Transparent Bidding

I Built a Pay-to-Rank Leaderboard Where Products Compete Through Transparent Bidding

Product Hunt resets every 24 hours. SEO takes months. Traditional ads are opaque.

I built something different: a leaderboard where your rank is permanent, every bid is public, and you only pay the gap to climb.

Here's the tech behind Steal the Spot.

The Problem

Product Hunt votes reset daily — your #1 spot is gone tomorrow
SEO takes months — by the time you rank, competitors have caught up
Traditional ads are opaque — you never know if you're getting fair value
Leaderboards are either pay-to-play or popularity contests

What if there was a leaderboard where:

Your rank is permanent (until someone outbids you)
Every bid is public and transparent
You only pay the difference when raising your bid
You get email alerts when outbid with exact price to steal back

How It Works

1. List FREE ($0)

Paste your product URL, pick a category, get on the board instantly. No credit card required.

2. Pay the Gap to Climb

Rank = cumulative bid. Every dollar moves you up. When raising your bid, you only pay the difference (minimum raise: $2).

3. Hold #1 or Outbid

Take any rank including #1. When rivals outbid you, get an instant email alert with the exact price to steal your spot back.

The Architecture

┌─────────────┐     ┌──────────────┐     ┌─────────────┐
│   Next.js   │────▶│   Supabase   │────▶│    Dodo     │
│   16 App    │     │  Postgres +  │     │  Payments   │
│   Router    │     │    RLS       │     │  (INR/UPI)  │
└─────────────┘     └──────────────┘     └─────────────┘
       │                                        │
       ▼                                        ▼
  ┌─────────┐                            ┌─────────────┐
  │  React  │                            │  Webhooks   │
  │  Three  │                            │  (Refunds)  │
  │  Fiber  │                            └─────────────┘
  └─────────┘

The Bidding System

No deposits, no refunds — bids are final and public. The rules are simple and server-authoritative:

Your bid IS your rank — highest cumulative bid sits at #1, ties break to whoever got there first
Pay the gap to raise — already bid $5 and want $20? You pay $15, not $20 (minimum raise: $2)
Taking #1 costs leader bid + $2 — the reclaim price is always public, and outbid losers get it by email with a one-click fight-back link

The Math

export function calcMinOutbid(currentBid: number, minRaise: number = 2): number {
  return currentBid + minRaise;
}

export function calcRaiseCost(currentBid: number, targetBid: number): number {
  return targetBid - currentBid; // pay the gap, not the full amount
}

Why server-authoritative matters

Rank previews never override the webhook. Concurrent bids are resolved with transactional locking (steal_apply_bid with advisory locks) and idempotent Dodo webhooks — two agents outbidding each other at the same second can't corrupt the board. Race-tested, not hoped.




## Spot City: The Visual Layer

Built an interactive 100-lot city grid called Spot City ([stealthespot.lol/spotcity](https://www.stealthespot.lol/spotcity)):

- Taller towers = more bids
- LOT 001 holds rank #1 (center plaza)
- Tap any building to inspect its product profile
- Tap any dashed lot to claim it immediately

## Tech Stack

| Layer | Technology |
|-------|------------|
| Frontend | Next.js 16 App Router, React Three Fiber |
| Database | Supabase (Postgres + Realtime + RLS) |
| Payments | Dodo Payments (INR/UPI native) |
| Hosting | Vercel |

### Key Features

- **Real-time leaderboard** — Supabase Realtime for live updates
- **Automatic refunds** — Dodo webhooks handle losers' deposits
- **RLS policies** — Row-level security for bid integrity
- **3D visualization** — React Three Fiber for product previews
- **INR/UPI** — Native Indian payment support

## Featured Slots

For brands that want guaranteed visibility:

- **30-day lease** at $50/mo
- **Placement above the leaderboard**
- **Premium visibility**
- **8 slots available**

Not pay-to-rank. Pay-for-placement.

## Current Stats (refresh from [/stats](https://www.stealthespot.lol/stats) before publishing)

- 15+ categories (AI, SaaS, Dev Tools, Marketing...)
- Free entry ($0) + pay-from-$2 climbs
- Live SVG rank badges, free JSON API (`GET /api/board`), 11 free SEO tools

## What's Next

- Seasons (board resets so there's always something to win)
- More category boards from demand
- Outbid-email analytics for sellers

## Try It

1. Go to [stealthespot.lol](https://stealthespot.lol)
2. Click "List Free"
3. Paste your product URL
4. You're on the board

If you want to rank up, place a bid. If you get outbid, you'll get an email.

🚀 Introducing RESTerX: An Open-Source, Lightweight, and Powerful API Testing Tool for Developers

pr0biex — Fri, 29 Aug 2025 19:36:19 +0000

Whether you’re building RESTful APIs or testing integrations with third-party services, API testing is a daily task for developers. Tools like Postman, Insomnia, and Thunder Client have their place, but they can feel heavy, bloated, or just too much for what should be a simple HTTP request.

Why RESTerX?

While popular tools are powerful, many are closed-source, come with telemetry, or eventually push users towards paid tiers. RESTerX is:

🔓 Completely Open Source
🧼 Lightweight and clean UI
💻 Cross-platform CLI & Web UI
🔒 Privacy-first (no data sent externally)
It’s everything you need to test APIs without the bloat.

A Postman-like Web UI — Without the Bloat

The web interface is fast, responsive, and mirrors the familiar layout of Postman — with some major perks:

🌓 Dark/Light Mode Toggle
🧠 Request History saved in localStorage
🧾 Custom Headers, Auth, and Body Tabs
📦 JSON/Raw/Form support with syntax highlighting
🔍 Real-time status, response time, and headers display
And yes, it looks awesome on both desktop and mobile.

To get started:

./restcli web

Open your browser at http://localhost:8080 (or your custom port).

Press enter or click to view image in full size

CLI Interface — For Terminal Lovers

Sometimes, you just want to stay in the terminal. RESTerX brings a menu-driven CLI that supports all HTTP methods and runs seamlessly on Windows, macOS, and Linux.

Launch it with:

./restcli
Choose your method, input your URL, and you’re ready to go. Fast, minimal, and distraction-free.

Built with Go for Performance

Go (Golang) is known for its speed, portability, and concurrency. RESTerX leverages these strengths to give you a tool that:

Starts instantly
Has a tiny memory footprint
Compiles to a single binary
No Electron. No memory hogs. Just solid performance.

🔧 Installation is Simple
If you have Go installed, just clone the repo and build:

git clone https://github.com/AkshatNaruka/RESTerX
cd RESTerX
go build -o restcli ./cmd

That’s it. No dependencies, no Docker, no drama.

Testing APIs Made Easy

RESTerX supports:

✅ All standard HTTP methods: GET, POST, PUT, PATCH, HEAD, DELETE
🔐 Bearer and Basic authentication
🧾 Custom headers
📝 Request body in JSON, form data, or raw text
📊 Formatted responses with copy-to-clipboard support
Want to test a local microservice or a public API? RESTerX handles both seamlessly.

Privacy by Design

No login. No telemetry. No cloud sync.

All your data stays in your browser (via localStorage) or on your machine.

In a time where even developer tools track usage and send data, RESTerX is a breath of fresh air.

🔥 Why Developers Love RESTerX
🧠 Zero learning curve — Designed to feel instantly familiar
💥 Fast and responsive — Built with performance-first mindset
🛠️ Hackable and extensible — Open-source with clear structure
🌍 Works offline — No network needed for local API testing
Whether you’re working on backend services, testing microservices, or just poking at REST APIs, RESTerX deserves a place in your toolkit.
