How I Built a Real-Time Stock Tracker for a Roblox Game with 0 Marketing Budget

August 6, 2025

Hey Indie Hackers! 👋

I recently launched a side project called Grow a Garden Stock – a real-time inventory tracker for the Roblox game Grow a Garden.

It's a simple tool that helps players track in-game shop stock (Seeds, Gear, Eggs, etc.), see countdowns for when items refresh, and even monitor in-game weather changes.

🧩 Why I Built It

As a casual player myself, I noticed one frustrating thing: the best items in the game appear randomly, and it’s really hard to keep track of what’s available in each shop at any time. Most players just keep refreshing the page or wait for Discord pings (which are delayed).

So I decided to build a browser-based, no-login, real-time stock viewer that anyone could use.

🔧 How It Works

It scrapes public in-game data every few seconds
Organizes items by category (Seeds, Gear, Cosmetics, etc.)
Shows countdown timers for when each category refreshes
Includes weather data to help users plan their garden
Works on both desktop and mobile

No login, no ads, no fluff. Just the info you need.

📈 Growth So Far

The tool has grown to 1,000+ weekly page views, mostly through word-of-mouth.
I shared it in a few Roblox Discord servers, and players started using it daily.
Some even requested features like push notifications or filters by rarity.
