Free Reddit tools
Subreddit rules checker
Check subreddit rules, self-promotion risk, link risk, and safer actions before posting.

Rules can change and moderators make final decisions. Treat this as a safety check, not permission to post.
How this free tool helps SaaS founders
Every Rankhog tool is built around the same rule: Reddit visibility only compounds when the contribution helps the thread first. Use the free result as a practical check before a higher-risk post, comment, or search visibility play.
How to use it
Enter a subreddit name or URL. Use the result before drafting so you do not build a post around an angle the community will reject.
What the output means
If the subreddit is strict, Rankhog may recommend waiting, warming the account, or answering existing threads instead of posting.
Example input and output
The live tool runs with your own context. This static example shows the kind of practical answer the page is designed to produce.
Sample input
- Subreddit
- r/SaaS
Rules and risk summary
This subreddit can work for SaaS discussion, but link-first launch posts are risky.
- Promotion risk: high
- Safer action: ask a specific founder question without a link
- Source: Reddit rules and Rankhog verified guidance
Use it with subreddit-specific context
Pair the tool with Rankhog's subreddit guides when you are posting somewhere strict. The guides cover rules, stats, what works, and removal risks.
