exe.dev is the company blog at blog.exe.dev, writing about programming and ai. Since 2025, 48 different Hacker News readers have linked it 88 times, most often “SSH has no Host header”. It is still writing: the last post was on 2026-10-29, and you can follow it by feed.
Too few sampled comments (18) to say how often HN recommends it.?
Why HN links it
The exe.dev team's engineering blog, linked for posts on SSH host-header routing, the cost of long Claude Code contexts, replacing CI, and open-source devtools.
Summarised by Claude from a sample of 18 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Notes from the exe.dev team on AI coding agents, cloud dev environments, and building software with Shelley.

You can work it around with socks5 protocol, it's designed for such cases and it has some merit for server side: https://blog.exe.dev/ssh-host-header

HN discussionIf you look at the actual cost of your Claude Code conversations, you'll see that the cost is overwhelmingly dominated by the cost of input tokens (cached). Because of how we construct persistent conversations, each cached input token incurs cost on each API request, meaning that component of cost scales with O(request count). If you graph the cost curve of a claude code session, it's very obvious that this scaling…

HN discussionIts crazy that people think caching is such a silver bullet, despite the cost of long context windows still being ridiculously high even with caching. https://blog.exe.dev/expensively-quadratic https://news.ycombinator.com/item?id=47000034

HN discussionThe referenced https://blog.exe.dev/replace-your-ci is resonating with me. I'm spending a relatively large amount of time waiting for CI to finish running, then clicking a button for an agent to fix failures, then waiting for CI to finish again. Might as well push that down into the core development loop. Do folks have advice for doing this in practice? Hooks in the harness? Pre-commit hooks? Different GitHub config…

HN discussionHi, author here. FWIW, the only people I coordinated with are my colleagues at exe.dev. Philip wrote a blog post a week ago on the topic too: https://blog.exe.dev/customizing-shelley . In retrospect, I should have sent drafts of this to other people I know thinking about new dev tooling to get their feedback! A bit more private discussion could have let me polish this more. We are all busy discovering the shape of n…

HN discussioni really hope OpenCode v2 with the Effect internals can ascertain and realize and lock on to being the best extensibility platform, on to having a core that serves not just itself, it's conceits of/as product, but a wider world. a street that wants to "find it's own uses for things". it feels like there's still a strong layer of "for us" vs "for you" within opencode, that i hope, over time can get chewed away at. pl…

HN discussionThe latest post from the very interesting exe.dev project (previously of 'I am building a cloud' [0]). They have a lot of interesting work that goes in to making SSH work with their system (eg previously [1]), and this is a continuation of that. Using Unix sockets to transfer file handles is not a new idea, but using for SSH connections is interesting to me. I wish it were a little heavier on the details here, but o…
