What this launch shows

From an account with 862 followers, this reached 98.1 times the account's own following. The median for under 5K followers is 158.1 times, so this one stayed closer to home than most.

It ranks 564 of 869 launches from accounts that size. Against every launch in the directory it is below the median of 569K views, at rank 2009 of 2575.

Saves led. 2K people bookmarked it, 212.2 per 10,000 views against a directory median of 12.1. A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does.

The rest: 79 replies, 16 quotes, 111 reposts. One bookmark for every 0.7 likes is a high ratio and usually means a product people intend to try.

The first line is “Introducing: 0 - the open-source AI security harness by @0securitylabs (YC F26)”, the same first word as 25% of launches in the directory. It carries a 45-second video against a directory median of 66 seconds. Videos between 30 and 90 seconds have a median of 484K views in the directory.

The copy runs 44 words, about the usual length for a launch post here, where the median is 42. The body carries a link, so the post had somewhere to send the reader and paid a little reach for it.

It went out on a Sunday. Launches posted on a Sunday have a median of 311K views in the directory, and Wednesday is the strongest day at 619K.

Launching a product on X from a small account covers this: an account with 862 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.
