Small tools that watch the web for you.

HarvestWorks builds narrow, dependable monitors for public data. Point one at what you care about, schedule it, and get only what changed. You pay per result, not per month.

Apps

Each one does one job. The monitors run on Apify, so they also work from AI agents through Apify's MCP server.

How it works

Same pattern for every monitor.

1. Tell it what to watch

Store URLs, stock tickers, or keywords. Nothing to install.

2. Put it on a schedule

Hourly or daily. Each run returns only what's new since the last one.

3. Pay for results

A fraction of a cent per item found. Errors are free, and you never pay twice for the same item.
