TipSkip r/startups. Mods removed 73% of founder posts last 30d. Punch into r/SaaS instead — same audience, 1/8th the gatekeeping.

Stuff people who built actual things have said.
“Saved me from getting nuked in r/startups for the 7th time. Found 4 subs I'd never even heard of that converted way better.”
Mira ChenFounder, Threadly · @mirabuilds
“Ran my SaaS through this on a Tuesday. By Friday I had 1,200 signups from a sub with 8k members. Absurd ROI on a free tool.”
Jonas PetrovSolo dev, Clipnote · @jonas_codes
“The mod strictness score alone is worth paying for. Honestly criminal that this is free.”
Devi R.Growth, OS Studio · @devs_devi
“Was about to spend $400 on a Reddit growth course. Used this instead. Got better data in 90 seconds.”
Sam AokiIndie hacker · @samships
/ Why this exists
I got banned 6 times before I learned which subs actually want founders.
Two years ago I launched a tiny B2B SaaS. I spent three weekends crafting “the perfect Reddit post” and got it deleted within 12 minutes. Different sub, same outcome. Then a temp ban. Then a permanent one.
I rebuilt my account, took notes on every sub I posted in, and made a spreadsheet. The spreadsheet became a script. The script became this.
Now founders use it 2,800+ times a month to skip the part where Reddit hates them. If that sounds useful, the input box is right at the top.

Subreddit analyzer FAQ — what people ask before they trust a free tool.
What is a subreddit analyzer?+−
A subreddit analyzer is a tool that scans Reddit and ranks subreddits by how well they match a given product or idea — using engagement data, mod strictness, link policy, and historical posting outcomes. SubredditAnalyzer is a free subreddit analyzer built for founders who keep getting their posts deleted.
How does SubredditAnalyzer rank subreddits?+−
We crawl public Reddit data and score each sub on five axes: topical fit, engagement rate, mod strictness, link tolerance, and best posting window. The output is a ranked list with a single score per subreddit so you can pick the top 3 in seconds.
Do I need a Reddit account?+−
No. The tool reads public Reddit data — your account stays out of it. You only need an account when you actually go post.
How fresh is the data?+−
We re-crawl every active sub at least once every 24 hours. Top subs every 6 hours. Mod activity and posting windows shift in near real time.
Will mods know I used this?+−
No. Mods see what Reddit shows them — a normal post from a normal account. We never touch your account or stamp anything on your posts.
Why is the free tier so generous?+−
Because the goal is to get you onto a paid plan once you see the value. One subreddit on the free tier is enough to prove the tool works — then upgrade to track the rest of your funnel.
