Superset – Terminal to run 10 parallel coding agents
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/needs attention, - A diff viewer to review the changes and make PRs quickly We’re three engineers who’ve built and maintained large codebases, and kept wanting to work on as many features in…
In plain words
Superset is an open-source terminal for running multiple coding agents like Claude Code and Codex in parallel. It automates git worktree creation and environment setup while keeping agents isolated to prevent conflicts. The tool includes built-in notifications for when agents complete work and a diff viewer for reviewing changes and creating pull requests quickly. It's designed for developers managing large codebases who want to work on multiple features simultaneously.

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/needs attention, - A diff viewer to review the changes and make PRs quickly We’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: https://www.youtube.com/watch?v=pHJhKFX2S-4 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'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's early days, but we’d love you to try Superset across all your CLI tools and environments, we welcome your feedback! :) [0] https://code.claude.com/docs/en/hooks [1] https://git-scm.com/docs/git-worktree

Hi HN, We’re Kiet, Avi, and Satya. We built an open-source desktop app that helps you run a lot of CLI coding agents like Claude Code, Codex, etc. in parallel on your machine. The purpose is to keep you unblocked - spin up new coding tasks while others run, and quickly switch between them as they need your attention. Superset aims to be a superset of all the best AI coding tools. We want to support and stay compatible with whatever CLI agents you already use - improving your workflow instead of replacing it. How it works: - One-click Git worktree creation with automatic environment setup -…

Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
