Show HN: CommoWatch – Alerts for Commodity Prices (Gold, Oil, Wheat, etc.)

2•anthonytorre•1d ago
Hey HN

I’m a solo developer building CommoWatch, a minimal web app to track commodity prices and get alerts when they hit your target.

The idea is simple:

- You pick the commodities you care about (gold, oil, wheat, gas...)

- You set the prices you want to be notified at

- You get an email or SMS when it happens.

It’s meant to be compact, fast, and useful for traders, investors, or even small business owners who follow material costs.

I’m starting small — just a few commodities, hourly updates, and email alerts first — to validate if people actually find it useful.

If this sounds interesting, you can join the waitlist here: https://getwaitlist.com/waitlist/31756

I’d love to hear your thoughts: What feature would make this genuinely useful to you? Or what do you think most people following commodity prices actually need?

Thanks!

What feature would make this genuinely useful to you?

Basic info on how the service works and what it will cost.

- How many commodities can I input?

- How often are prices checked?

- Can I enter a price range (low/high) to receive an alert if it moves outside the range?

- Cost?

anthonytorre•1d ago
Good questions, thanks for asking!

Right now I'm keeping it simple for the MVP:

- You'll be able to track about 5 major commodities at launch (gold, silver, oil, gas, wheat).

- Prices are checked every hour from a real market data API.

- You can set alerts for "above" or "below" a specific price (range alerts are planned later).

- Notifications will start with email (SMS later).

The goal is to validate if people actually want a simple alert tool before adding more advanced features.

Pricing will be:

- Free tier: up to 3 commodities and 3 email alerts.

- Pro: €5/month for unlimited commodities and alerts (email).

- Later: a €15/month plan for SMS alerts.

Trying to keep it lightweight and affordable for now.

And "€" because I'm european (but will maybe charge in "$" if most of the users are from the US).

>>> - Prices are checked every hour from a real market data API. <<<

An hour can be a long time in trading terms.

Are you aware that some web sites already offer similar service for free?

Example: investing.com or marketwatch.com which is a subsidiary of Dow Jones & Company.

anthonytorre•1d ago
Yeah, totally. An hour is definitely a long time in trading terms.

I’m not trying to compete with full-blown trading platforms or real time feeds like investing.com or MarketWatch.

The goal is more of a "lightweight companion". Something super simple that lets you track a few commodities and get a ping when a price crosses a level you care about, without dashboards, ads, or login clutter.

Think more "quiet price radar for long-term investors" or "small businesses watching material costs" rather than day-trading tool.

If I see more people asking for shorter intervals, I could always move to 10-minute checks later.

But for now I’m keeping it simple to start.
