How it compares
A launch means nothing against no one. These are the launches it is actually comparable to, and where this one sits among them.
| Compared with | Launches | Median views | This one | Rank |
|---|---|---|---|---|
| Developer tools launches from accounts 25K to 100K followers | 76 | 565K | 0.7x | 45 |
| Product release the same kind of announcement | 1150 | 566K | 0.7x | 655 |
| 25K to 100K followers accounts of a similar size | 314 | 812K | 0.5x | 206 |
| Every launch all of them, for scale | 2314 | 603K | 0.7x | 1354 |
What this launch shows
GitHub Next posted this from an account with 29K followers and reached 13.4 times that many people. Accounts of that size usually reach 17.1 times their following, so this is in the normal range.
It ranks 206 of 314 launches from accounts that size. Against every launch in the directory it is below the median of 603K views, at rank 1354 of 2314.
Saves led. 3K people bookmarked it, 78.3 per 10,000 views against a directory median of 12. A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does.
The rest: 86 replies, 78 quotes, 131 reposts. One bookmark for every 0.7 likes is a high ratio and usually means a product people intend to try.
The post opens with “How do you _guarantee_ your agent's code is correct”. It carries a 34-second 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 48 words, about the usual length for a launch post here, where the median is 41.
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 Wednesday. Launches posted on a Wednesday have a median of 622K views in the directory, and Friday is the strongest day at 647K.
Attributing signups to a launch covers this: a save rate this high is the number to follow into the product. For the next one, read developer marketing strategy: developers try before they read, so the post has to let them.
X analytics explained is the guide for it: what each of these numbers means, with benchmarks by account size. Every launch we track in Developer Tool is on that vertical's directory page.
