SubredditStats Review
Free subreddit analytics with growth charts, subscriber rankings, and community overlap analysis
SubredditStats is a free, no-login tool that gives you surprisingly useful snapshots of subreddit growth, subscriber counts, activity rates, and community overlap. It is best used as a research aid when you are deciding which subreddits to target for outreach or content strategy. The data has acknowledged accuracy limitations, the maintainer notes it is a hobby project and the collector is not robust. For quick directional research it is excellent. For anything requiring precise data or API integration, you will need to combine it with more capable tools.
Pros and cons
- Completely free with no account required
- Community overlap analysis (which subreddits share the same users) is genuinely useful for targeting
- Keyword frequency tracking over time in Reddit comments is a rare free feature
- Network visualizations help identify adjacent communities worth engaging
- Covers multiple ranking dimensions: subscriber count, growth rate, posts per day, comments per day
- No API or data export, all analysis is manual through the web interface
- Accuracy is explicitly flagged as unreliable by the tool itself, use only as directional guidance
- Hobby project with no SLA, feature updates, or support timeline
- No brand mention monitoring, keyword alerts, or any active notification features
What is SubredditStats?
SubredditStats is a free website that surfaces statistics and ranking data about Reddit communities. You can browse subreddits by subscriber count, subscriber growth, posts per day, comments per day, and engagement ratios. Clicking into a specific subreddit shows historical growth charts and activity graphs that give you a quick sense of whether a community is growing, stable, or declining.
The most analytically useful features are the community overlap analysis and keyword frequency tracking. The overlap tool shows which other subreddits the commenters and posters in a given community also participate in, which is valuable for finding adjacent audiences when you are planning where to invest in organic Reddit engagement. The keyword tracker shows how often specific terms appear in a subreddit's comments over time, which can surface trending topics or validate whether your niche is actively discussed.
The tool comes with an important caveat baked into the homepage itself: the data collector is not robust and the numbers should be used only as a general guide. This is an honest disclaimer for a free hobby project, and it does not disqualify the tool for early-stage research. It just means you should verify any critical decisions with additional sources before committing to a strategy.
Core features
Subreddit Statistics with Growth Graphs
Each subreddit page includes historical charts for subscriber count, post volume, and comment activity. You can quickly assess whether a community is growing or plateauing before investing time in it. The time-series view goes back months or years for established subreddits.
Ranking Lists by Subscriber Count and Activity
The homepage surfaces ranked lists across multiple dimensions: largest by subscribers, fastest growing by day, week, month, and year, most posts per day, most comments per day, and highest engagement ratios. Useful for finding active communities in a niche you are not already familiar with.
Network Visualizations
SubredditStats can generate network graphs showing which subreddits are closely related based on shared users. These visualizations help you map a niche and find communities you might not have discovered through direct search.
User and Commenter Overlap Analysis
The overlap tool identifies which subreddits share a significant portion of users with a given community. If your target audience is in r/entrepreneur, the overlap analysis might reveal they are also active in r/startups, r/SaaS, and specific industry verticals, which expands your targeting list efficiently.
Keyword Frequency Tracking
Track how often specific keywords appear in a subreddit's comments over time. This is useful for validating whether your product category or pain point is actively discussed in a community, and for spotting when a topic starts trending before it peaks.

Who it is for
Anyone planning a Reddit content or outreach strategy who needs to quickly evaluate which subreddits have the right size, activity level, and audience overlap before committing time to engagement.
People studying Reddit community dynamics, growth patterns, or topic trends who need free historical data without setting up a formal research tool.
Practitioners identifying which subreddits are active enough and large enough to be cited by AI models and search engines as authority sources in a given category.
Verdict
SubredditStats is a useful free research tool for anyone making decisions about which Reddit communities to target. The community overlap analysis alone is worth a bookmark. Just accept the accuracy limitations upfront and use it for directional research rather than precision data.
