I built an ISP infrastructure emulator from scratch with a custom vBNG

In plain words

Aether is an ISP infrastructure lab that emulates broadband network operations end-to-end using multiple virtual Broadband Network Gateways. Built with Containerlab, it handles IPoE IPv4 subscriber management, RADIUS authentication, per-subscriber traffic shaping, and traffic simulation. The project runs a Python-based vBNG and is designed for developers and network engineers studying ISP infrastructure and subscriber management systems.

  Since coding agents like Claude Code and Codex came out, I've been pretty obsessed with them. It's hard not to when you're getting a 20x discount on inference. I've also been frustrated by them a lot. I hated walking around with my laptop lid open while connected to a hotspot on my phone, having to tediously accept commands so I don't lose my root directory, and running out of RAM when running multiple agents that were spinning up dev servers in different worktrees at once. A lot of people would say existing cloud agents are the solution to this, as none of the above problems apply to any…

  Aether – Background agents that fix bugs in isolated VMs, opens PRsFeb 2026 · ▲8

  Hey HN, I've been building Aether, a background agent that takes production errors from Sentry and attempts to turn them into verified pull requests. When a new error hits your Sentry project: 1. Sentry webhook fires with the stack trace, breadcrumbs, and context 2. Aether spins up an isolated Fly.io VM and clones the repo at the relevant commit 3. Agent analyzes the stack trace, reproduces the issue, proposes a fix 4. Starts the dev server, re-runs tests, and can verify the running app with Playwright (headless Chromium is pre-installed in every VM) 5. A review pass evaluates the diff…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
