When it comes to competitor research, few places on the internet rival Reddit for raw, unfiltered opinions. Unlike review sites where companies can curate testimonials, or social media platforms where brand accounts control the narrative, Reddit is where real users go to vent frustrations, praise features they love, and ask the community for better alternatives. There is no PR spin here -- just honest conversations between people who actually use the products.
The challenge is knowing where to look. Reddit has millions of communities, and the most valuable competitive intelligence is scattered across industry-specific subreddits where users naturally compare tools, share migration stories, and debate which solutions are actually worth paying for. We have curated the 10 best subreddits for competitor research so you can start gathering actionable intelligence today.

How to Get the Most from Competitor Research on Reddit
Finding the right subreddits is only the first step. To turn Reddit conversations into actionable competitive intelligence, you need a systematic approach. Start by searching for your competitors by name within these communities. Look for threads that mention "alternatives to," "vs," "switching from," and "review" alongside competitor names. These search patterns surface the most comparison-rich discussions.
Pay close attention to recurring themes. If multiple users across different subreddits complain about the same feature gap or praise the same capability, that is a strong signal worth acting on. Track which competitors appear most frequently in recommendation threads and note what specific qualities users cite when recommending them.
With Reddily, you can accelerate this process significantly. Instead of manually reading through hundreds of comments, paste any Reddit thread URL and get AI-powered analysis that extracts key themes, sentiment patterns, and actionable insights in seconds. Use batch analysis to process multiple competitor threads at once and build a comprehensive picture of your competitive landscape without spending hours scrolling through discussions.
