How to use this list

These are the safest posts you will ever make on Reddit: the thread exists so that promotion has somewhere legal to go, so there is no rule to break and no account to risk. The trade is that everybody else is in there too, which makes the entry itself the whole game — two legible lines and a plain link beat a paragraph of positioning.

The part almost nobody does, and the part that actually works: reply to three other people’s entries. The thread is full of founders who will look at your profile and try your thing, and it builds the participation history that lets you comment safely in the rest of that subreddit later.

Full version in the guide to free SaaS promo threads, and if you want to know where else you are allowed to post, the subreddit rules checker is the other free tool.

Questions

What is a free SaaS promo thread?+

A recurring thread in a subreddit where posting about your own product is explicitly allowed — usually because the subreddit bans self-promotion everywhere else and contains it here instead. You cannot break a rule by doing the thing the thread exists for, which makes these the lowest-risk place to start on Reddit.

How often is this list updated?+

This page refreshes weekly. ReplyHey itself sweeps for these threads every day — customers see them the morning they appear, and this public copy catches up within the week. Threads older than 45 days drop off either way, because a locked thread is a wasted click.

Do I need an account to use this?+

No. There is no signup, no email wall and no limit. Paying customers get the same list filtered to what they have not posted in yet, plus the leads and the drafts.

How should I write my entry?+

One line on what it does and for whom, the specific unusual thing about it, what you want from readers, and a plain link with no tracker. Then reply to three other people’s entries — that is where the users actually come from.

The threads where someone is asking for what you built

Promo threads are the safe start. The leads are the point: ReplyHey finds the posts where someone has the problem you solve, scores them, and drafts the reply.
