Took some time off work to recharge this summer and built this: https://chromewebstore.google.com/detail/hn-followblock/dkbnpfgpgljemihbcdmadffanebbjacc
It’s my first Chrome extension. Largely built by Claude Code honestly. I just wanted to understand the process of building an extension, testing it locally in dev mode, and publishing it to the Chrome official store. Spoiler: it costs a one-time fee of $5.
They ask you to submit screenshots with specific image dimensions. And there is a review after you submit. But generally a pretty smooth process.
This extension I released lets me follow certain users on HN. Sometimes you read a comment on there and realize you want to always keep up with everything this person is posting. Sometimes the opposite is true so you may want to block. But my main use case is Follow.
