The problem
Every subreddit has different rules. Guess wrong and you're banned.
One sub bans self-promo on sight. The next one runs on it. Reading a wall of rules and scrolling months of posts to figure out which is which — for every community — is the tax you pay to market on Reddit. Subreddit Scout pays it for you, in one click.
What you see in one click
A full read on the room, before you say a word.
Self-promo tolerance score
A 0–100 read on how welcome promotion is in this sub, with a plain verdict like “Promo-friendly with rules” or “High risk — read the rules.”
Rules digest
The subreddit's rules summarized in a clean accordion, so you catch the self-promo ratio and the landmines without reading a novel.
Mod strictness
A quick strictness read based on rule count and posting restrictions — so you know how tightly the community is policed before you post.
Best times to post
The windows when this sub is actually awake and voting, derived from its recent top posts and shown in your local timezone.
Community size at a glance
Subscriber and active-user counts, so you can weigh reach against how strict the room is.
Zero setup
Pin it once. From then on it's a button on every subreddit page — no account, no dashboard, no API keys.
The score, decoded
One number that tells you how hard to hold back.
The tolerance score reads the sub's rules, restrictions, and how it moderates self- promotion, then lands on a single 0–100 verdict. High means you can be direct. Low means lead with value and keep the link subtle — or skip the pitch entirely.
How it works
Installed in a minute. Useful on every sub after that.
01
Add it to Chrome
One click from the Chrome Web Store. It's 18 KB, no account, and asks for nothing but access to reddit.com to do its job.
02
Open any subreddit
Head to any r/ page and hit “Scout this subreddit.” The panel reads Reddit's own public data for that sub on the spot.
03
Post with the room in mind
Score, rules, strictness, and timing — all in front of you. Now you write a post that fits instead of one that gets removed.
Built by a Reddit growth agency
The check we run before every client post — now a button in your browser.
We've shipped hundreds of Reddit campaigns and the fastest way to get a client banned is posting into a sub you haven't read. Subreddit Scout is the exact pre-flight our team runs, packaged so you can run it yourself for free.
Reads public data only
It reads the same public JSON Reddit already serves for the sub you scout — never your account, your posts, or any other site.
Nothing leaves your browser
Results cache locally for 24 hours so repeat checks are instant. Nothing is sent to our servers. No AI, no accounts.
No tracking, ever
We don't collect your name, location, or browsing history, and we don't sell or share anything. Two permissions, both obvious.
The fine print lives in the privacy policy.
FAQ
Questions, answered.
Is it really free?
Yes. No account, no trial, no paywall. Add it to Chrome and use it on every subreddit.
Does it work on any subreddit?
Any public subreddit. Open the sub, click “Scout this subreddit,” and the panel reads that community's public data on the spot.
Does it need my Reddit login?
No. It never touches your Reddit account. It only reads the public information Reddit already serves for the subreddit you're viewing.
How is the tolerance score calculated?
From the sub's rules, its posting restrictions, and how it treats self-promotion — distilled into a single 0–100 verdict so you know how direct you can be.
Which browsers are supported?
It's a Chrome extension, so it works in Chrome and Chromium browsers like Brave, Edge, and Arc.
