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, 62% 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. 2.5× 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 top posts went up at 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?
No. Upvotecast doesn’t post for you. It shows you the rules before you cross them.
Does it write posts?
No. Redditors spot generated posts, and some subreddits ban them. You write it.
Which subreddits?
Any public one. Six are live today.
Different from reading the rules?
Rules say what’s banned. Upvotecast says what wins.
How is best time calculated?
From when the top posts went up. Day and hour, US Eastern.
GummySearch alternative?
Partly. They find where buyers talk. We show how to post there.
When?
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.
