Frequently asked questions

Are RedditMaster's free tools actually free?▾

Yes. Every tool on this page is free to use without a signup. Some have rate limits per IP to stay sustainable, but no payment, account, or trial is required to evaluate them.

What's the best free Reddit tool for finding subreddits?▾

Subreddit Finder if you start from a niche description; Website Subreddit Finder if you start from a URL. Both rank by audience fit, activity, and self-promotion tolerance — not just subscriber count.

How do I check if my Reddit account is shadowbanned?▾

Use the Shadowban Checker. Reddit User Analyzer also surfaces shadowban signals as part of a fuller account audit.

Which tool helps me avoid getting banned for self-promotion?▾

Promotion Risk Checker reads your draft post + the target subreddit's rules and flags violations before you submit. Pair with Subreddit Rules Summarizer.

When should I post on Reddit for the most engagement?▾

Use Peak Time Finder. Every subreddit has its own rhythm — generic 'best time to post' charts ignore that.

Can I find buyer-intent threads with these free tools?▾

Reddit Opportunity Finder surfaces buyer-intent posts in real time. Reddit Post Search adds filtering Reddit's native search doesn't expose. For ongoing 24/7 monitoring with AI-drafted replies and conversion attribution, that's Campaign Mode.

Do I need a Reddit account to use these tools?▾

No. They query Reddit's public data — you don't need to be logged in. You only need a Reddit account if you want to post or use Karma Mode and Campaign Mode.
