Show HN: Arcaide – Explore code with multi-level call graphs

A new Show HN project called Arcaide is pitching a very simple fantasy: take a messy software project and turn it into a visual map people can actually explore. You can click through sample repositories and watch the structure of a codebase unfold as multi-level call graphs — basically, a picture of which parts talk to which. And the first wave of reaction was pure classroom-core excitement. One commenter flat-out said they "love this" and could already picture it being used in lectures, which gives the whole launch a wholesome, teacher-approved glow.

But because this is the internet, the honeymoon lasted about three seconds before the interrogation began. The biggest mood in the comments? Curious suspicion. One person jumped in with the chaotic, very relatable "How u make this???" energy, while others immediately started poking at the black box. How does Arcaide decide what to show and what to leave out, especially when real projects can be giant spaghetti bowls? Another asked whether the diagrams are editable or if they’re strictly generated by artificial intelligence, which is where the tiny whiff of drama creeps in: people like shiny visuals, but they really want to know what’s under the hood.

Then came the classic nerd escalation: nice, but can it do more? One commenter wished it could trace data flow too, essentially saying, "Cool map, now show me the actual traffic." And another compared it to Ilograph, a subtle but unmistakable internet move that translates to: love the vibe, but you’ve entered a competitive arena now. In other words, Arcaide got the dream launch package — praise, questions, feature demands, and a comparison to a rival — which in tech-comment terms means people are absolutely paying attention.
