A launch means nothing against no one. These are the launches it is actually comparable to, and where this one sits among them.

What this launch shows

From an account with 526 followers, this reached 14.1 times the account's own following. The median for under 5K followers is 152.2 times, so this one stayed closer to home than most.

It ranks 704 of 743 launches from accounts that size. Against every launch in the directory it is below the median of 603K views, at rank 2247 of 2314.

Replies led. 64 of them, 86.5 per 10,000 views against a median of 2.5.

The post started a conversation, and the ranking model pays for conversation with reach in the hours after. Bookmarks came in at 20, reposts at 19.

The first line is “introducing Mirrors 🪞 find the mistakes your AI agent keeps making and fix them in real time”, the same first word as 25% of launches in the directory.

It carries a 1:07 video against a directory median of 66 seconds. Videos between 30 and 90 seconds have a median of 537K views in the directory.

The copy runs 46 words, about the usual length for a launch post here, where the median is 41. There is a link in the body, which costs a post some reach and buys it a place to send people.

It went out on a Friday. Launches posted on a Friday have a median of 647K views in the directory, which makes it the strongest day.

Launching a product on X from a small account covers this: an account with 526 followers has to earn every view from outside its own following. For the next one, read attributing signups to a launch: a save rate this high is the number to follow into the product.

Giving people something to reply to is the guide for it: the conversation is what carried this one. Every launch we track in Developer Tool is on that vertical's directory page.
