ChatterSift: monitor Reddit keywords for free, no API key required
ChatterSift is a free, open-source tool that alerts you when your chosen keywords appear on Reddit. It works using RSS feeds instead of Reddit's official API, so there's no registration or cost to get started.
Keeping track of what people say about a topic, brand, or product on Reddit normally requires Reddit's official API, which involves an approval process and potential costs. ChatterSift sidesteps this by using RSS, an older web standard that lets you subscribe to content without needing special access. You set up the keywords you want to watch, and ChatterSift notifies you when new Reddit posts containing those words appear.
Because the code is open source, you can host it yourself, inspect it, or adapt it to your needs at no cost. Practical uses include tracking mentions of your own project, watching competitors, or following niche topics. One limitation: RSS feeds from Reddit may not capture every post instantly or cover all subreddits comprehensively.
