Hey HN, we’re Avi, Kiet, and Satya. We’re building Superset, an open-source terminal made for managing a bunch of coding agents (Claude Code, Codex, etc) in parallel.- Superset makes it easy to spin up git worktrees and automatically setup your environment- Agents and terminal tabs are isolated to worktrees, preventing conflicts- Built-in hooks [0] to notify when your coding agents are done&#x2F;needs attention,- A diff viewer to review the changes and make PRs quicklyWe’re three engineers who’ve built and maintained large codebases, and kept wanting to work on as many features in parallel as possible. Git worktrees [1] have been a useful solution for this task but they’re annoying to spin up and manage. We started superset as a tool that uses the best practices we’ve discovered running parallel agents.Here is a demo video:<a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pHJhKFX2S-4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=pHJhKFX2S-4</a>We all use Superset to build Superset, and it more than doubles our productivity (you’ll be able to tell from the autoupdates). We have many friends using it over their IDE of choice or replacing their terminals with Superset, and it seems to stick because they can keep using whatever CLI agent or tool they want while Superset just augments their existing set of tools.Superset is written predominantly in Typescript and based on Electron, xterm.js, and node-pty. We chose xterm+node-pty because it&#x27;s a proven way to run real PTYs in a desktop app (used by VSCode and Hyper), and Electron lets us ship fast.
Next, we’re exploring features like running worktrees in cloud VMs to offload local resources, context sharing between agents, and a top-level orchestration agent for managing many worktrees or projects at once.We’ve learned a lot building this: making a good terminal is more complex than you’d think, and terminal and git defaults aren’t universal (svn vs git, weird shell setups, complex monorepos, etc.).Building a product for yourself is way faster and quite fun. It&#x27;s early days, but we’d love you to try Superset across all your CLI tools and environments, we welcome your feedback! :)[0] <a href="https:&#x2F;&#x2F;code.claude.com&#x2F;docs&#x2F;en&#x2F;hooks" rel="nofollow">https:&#x2F;&#x2F;code.claude.com&#x2F;docs&#x2F;en&#x2F;hooks</a>[1] <a href="https:&#x2F;&#x2F;git-scm.com&#x2F;docs&#x2F;git-worktree" rel="nofollow">https:&#x2F;&#x2F;git-scm.com&#x2F;docs&#x2F;git-worktree</a>

TL;DR explanation (go to <a href="https:&#x2F;&#x2F;github.com&#x2F;Sakura-sx&#x2F;Aroma?tab=readme-ov-file#tldr-explanation" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sakura-sx&#x2F;Aroma?tab=readme-ov-file#tldr-e...</a> if you want the formatted version)This is done by measuring the minimum TCP RTT (client.socket.tcpi_min_rtt) seen and the smoothed TCP RTT (client.socket.tcpi_rtt). I am getting this data by using Fastly Custom VCL, they get this data from the Linux kernel (struct tcp_info -&gt; tcpi_min_rtt and tcpi_rtt). I am using Fastly for the Demo since they have PoPs all around the world and they expose TCP socket data to me.The score is calculated by doing tcpi_min_rtt&#x2F;tcpi_rtt. It&#x27;s simple but it&#x27;s what worked best for this with the data Fastly gives me. Based on my testing, 1-0.7 is normal, 0.7-0.3 is normal if the connection is somewhat unstable (WiFi, mobile data, satellite...), 0.3-0.1 is low and may be a proxy, anything lower than 0.1 is flagged as TCP proxy by the current code.
