FleetCode – Open-source UI for running multiple coding agents
Hi HN! I've recently been finding productivity in running parallel CLI coding agents(after not believing in them initially). After having to do a ton of git stashing and branch fumbling, I decided I needed to something to more ergonomically run these agents in their own dedicated spaces. I tried a lot of the existing products but they either were too convoluted or flat out didn't work. Some of them also seem to roll their own chat UI which I don't think is the right approach, I wanted to something to lightly wrap my terminal sessions. So I built FleetCode! It uses git worktrees and let's you…
FleetCode – Open-source UI for running multiple coding agents launched on October 8, 2025 with 103 votes, #301 of 8,178 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
FleetCode is an open-source user interface for running multiple coding agents simultaneously in parallel CLI environments. It uses git worktrees to manage separate workspaces for each agent, eliminating the need for manual git stashing and branch switching. Designed for developers who want to streamline multi-agent coding workflows, FleetCode provides a lightweight terminal wrapper rather than building a custom chat interface. The tool addresses complexity issues found in existing products by offering a simpler, more ergonomic approach to parallel agent management.

Light-weight control pane to run CLI coding agents(Claude Code, Codex) in parallel - built-by-as/FleetCode
A desktop terminal application for running multiple CLI coding agents simultaneously, each in isolated git worktrees. npm install Usage Development npm run dev Production Build npm run build npm start How It Works Session Creation Select a project directory (must be a git repository) Choose a parent branch for the worktree Select your coding agent (Claude or Codex) Optionally add setup commands (e.g., environment variables, source files) FleetCode creates a new git worktree and spawns a terminal session Session Management New Sessions : Use --session-id <uuid> for first-time Claude sessions Reopened Sessions : Automatically resume with --resume <uuid> Worktrees : Each session gets its own…from github.com

Parallel CodeMar 2026 · parallelcode.app · ▲159I kept running into a structural problem with AI coding tools. You try one agent. It makes changes. You try another. Now you're manually diffing branches and cleaning up experimental commits. The tools are powerful, but the workflow isn’t designed for comparison. So I built Parallel Code. It runs Claude Code, Codex, and Gemini CLI natively (no API wrapper, no feature abstraction), but isolates each agent in: its own terminal its own Git worktree its own feature branch The workflow becomes: Spawn N worktrees Assign one AI agent per worktree Let them implement independently Compare diffs Merge…
Agent-of-empires: OpenCode and Claude Code session managerJan 2026 · github.com · ▲118Hi! I’m Nathan: an ML Engineer at Mozilla.ai: I built agent-of-empires (aoe): a CLI application to help you manage all of your running Claude Code/Opencode sessions and know when they are waiting for you. - Written in rust and relies on tmux for security and reliability - Monitors state of cli sessions to tell you when an agent is running vs idle vs waiting for your input - Manage sessions by naming them, grouping them, configuring profiles for various settings I'm passionate about getting self-hosted open-weight LLMs to be valid options to compete with proprietary closed models. One…

Talanoa▲340Hi 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…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
