Know what gets upvoted in a subreddit.Before you post.
Upvotecast reads a subreddit’s rules and its top posts. It tells you the self-promo limits, the best times, the formats that win, and if your product fits.
fig. 1 — a habit-tracker app with a 40-second demo. Ring = audience fit.
- Self-promo
- Allowed. Sharing what you built is the point.
- Best time
- Sun, 1–2am ET
- Top format
- Video, 63% of top posts
- Angle
- Demo first, then why you built it.
Six real subreddits, analyzed.
The rules, the 100 top posts of the past year, and when they went up.
r/startups
- Best times (ET): Thu 11am · Tue 7pm · Wed 2pm
- Titles: almost all end with “(I will not promote)”.
- Self-promo: strict. Only in the monthly Share Your Startup thread.
- Format: 100% text.
- Winning pattern: a milestone with a real number. 2.0× the median score.
Most posts get nothing. The ones that stay up keep paying.
A rule you never read.
r/marketing bans self-promo. r/startups counts any project you own as promotion.
A dead hour.
r/SaaS’s busiest hour for top posts: Thu, 4–5am ET.
The wrong format.
r/SideProject wants video. r/Entrepreneur is all text.
Google.
People add “reddit” to searches. A good thread ranks for years.
AI answers.
ChatGPT and Perplexity pull from Reddit.
No expiry.
An ad stops when you stop paying. A thread keeps getting found.

What people ask us.
Will I get banned?
Not because of us. Upvotecast never posts, comments or votes for you. It shows you the subreddit’s rules and self-promo limits before you post, and checks your draft against them. What you post is up to you.
Does it write posts?
Not from scratch. You write the post. Upvotecast checks your draft against the subreddit’s rules and what wins there, and Apply fixes rewrites your draft to fix the problems it finds. You review every change.
Which subreddits?
Any public one. Type a name and get its analysis. Ten ready-made analyses are public at upvotecast.app/r.
Different from reading the rules?
Rules say what’s banned. Upvotecast says what wins.
How is best time calculated?
From when the top posts of the past year went up. Day and hour, US Eastern.
GummySearch alternative?
Partly. Audience research tools find where buyers talk. Upvotecast finds communities for your product, then shows how to post there.
Do I need to connect Reddit?
No. Connecting Reddit is optional: it only adds your own karma and recent posts to your dashboard.
When can I start?
Early access, in batches. The waitlist hears first.
Stop posting blind on Reddit.
Rules, self-promo limits, best times, winning formats. Before you write a word. Then a check of your draft before you post it.
