# Validate a product idea: is anyone making money from it

Updated daily, last 2026-11-12

Got an idea? Check the comparables first: who published real revenue, what profit sellers report, and how many users similar extensions and apps have.

## Once connected, ask your agent

- Does anyone building restock-alert tools publish revenue, and how much a month?

- What multiple of annual revenue do similar products list for?

- How many Chrome extensions in this niche show any pricing?

## The tools it will use

- `data(lib='indie')`: search comparables with verified revenue

- `data(lib='forsale')`: revenue, profit and asking multiples of similar listings

- `products`: whether a comparable is among 3,000+ researched rising products

Advice is tied to specific cases with quotes, numbers, dates and sources; where the databases have no evidence, it says so.

## What a query returns today

From the [Verified indie product revenue](https://stringers.io/en/tools/indie-revenue.md) database: Products, median and total 30-day revenue (USD) by category.
