Hc: an agentless, multi-tenant shell history sink
This project is a tool for engineers who live in the terminal and are tired of losing their command history to ephemeral servers or fragmented `.bash_history` files. If you’re jumping between dozens of boxes, many of which might be destroyed an hour later, your "local memory" (the history file) is essentially useless.

In plain words
Hc is a centralized shell history tool for engineers who work across multiple servers. It captures and stores terminal commands and sessions in a permanent repository, preventing loss of command history when servers are destroyed or ephemeral. Instead of requiring agents on each machine, it reconstructs sessions from proxy connection recordings, capturing keystrokes and output without installation overhead. The tool solves fragmentation across dozens of boxes by building a searchable, persistent record of terminal activity accessible long after the original server is gone.

In the maker’s words, at launch
This project is a tool for engineers who live in the terminal and are tired of losing their command history to ephemeral servers or fragmented `.bash_history` files. If you’re jumping between dozens of boxes, many of which might be destroyed an hour later, your "local memory" (the history file) is essentially useless. This tool builds a centralized, permanent brain for your shell activity, ensuring that a complex one-liner you crafted months ago remains accessible even if the server it ran on is long gone. The core mechanism wants to be a "zero-touch" capture that happens at the connection gateway level. Instead of installing logging agents or scripts on every target machine, the tool reconstructs your terminal sessions from raw recording files generated by the proxy you use to connect. This "in-flight" capture means you get a high-fidelity log of every keystroke and output without ever having to touch the configuration of the remote host. It’s a passive way to build a personal knowledge base while you work. To handle the reality of context-switching, the tool is designed with a "multi-tenant" architecture. For an individual engineer, this isn't about managing different users, but about isolating project contexts. It automatically categorizes history based on the specific organization or project tags defined at the gateway. This keeps your work for different clients or personal side-projects in separate buckets, so you don't have to wade through unrelated noise when you're looking for a specific solution. In true nerd fashion, the search interface stays exactly where you want it: in the command line. There is no bloated web UI to slow you down. The tool turns your entire professional history into a searchable, greppable database accessible directly from your terminal.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
