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 |

What this launch shows
Builder.io posted this from an account with 136K followers and reached about 11.3% of them. Accounts of that size usually reach 2.4 times their following.
This one did not get far past the people who already followed it. It ranks 605 of 611 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1856 of 1981.
Saves led. 183 people bookmarked it, 118.7 per 10,000 views against a directory median of 11.7. A bookmark is a plan to come back, and it tracks signups and demo requests more closely than a like does.
The rest: 6 replies, 1 quotes, 13 reposts. One bookmark for every 0.9 likes is a high ratio and usually means a product people intend to try.
The post opens with “Introducing /webmcp - make your agent workflows visual”, the same first word as 25% of launches in the directory. It carries a 3:48 video against a directory median of 65 seconds. Videos over 90 seconds have a median of 651K views in the directory.
The copy runs 9 words, shorter than 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 880K views in the directory, which makes it the strongest day.
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 giving people something to reply to: the conversation is what carried this one.
Why posts from large accounts under-reach is the guide for it: a post seen by fewer people than follow the account was held back by the ranking model. Every launch we track in Developer Tool is on that vertical's directory page.
