worktree-compose

What it does

worktree-compose automatically gives every git worktree its own isolated Docker Compose stack. It solves environment conflicts when running parallel developers or AI agents by isolating ports, databases, caches, and containers with zero configuration. Launch multiple experiments, compare live URLs, and promote the best result.

Every worktree gets its own ports, database, cache, and containers — automatically.

  Docker rollout – Zero Downtime Deployment for Docker-compose2023 · github.com · ▲187

  docker-compose is great for single node docker deployments, but it doesn't have a feature that would allow zero downtime deployments. It's not possible to deploy often if your app goes down every time, and using Kubernetes/Nomad/Swarm on a single node is an overkill. I created this Docker plugin to be a drop-in replacement for the restart command in usual docker-compose deployment scripts. It performs a simple rolling deployment of a single service.

  Coasts – Containerized Hosts for AgentsMar 2026 · github.com · ▲99

  Hi HN - We've been working on Coasts (“containerized hosts”) to make it so you can run multiple localhost instances, and multiple docker-compose runtimes, across git worktrees on the same computer. Here’s a demo: https://www.youtube.com/watch?v=yRiySdGQZZA. There are also videos in our docs that give a good conceptual overview: https://coasts.dev/docs/learn-coasts-videos. Agents can make code changes in different worktrees in isolation, but it's hard for them to test their changes without multiple localhost runtimes that are isolated and scoped to those…

  KeystoneMar 2026 · github.com · ▲125

  We kept hitting the same wall: you clone some arbitrary repo and just want it to run without any configuration work. So we built Keystone, an open source tool that spins up a Modal sandbox, runs Claude Code inside it, and produces a working .devcontainer/ config (Dockerfile, devcontainer.json, test runner) for any git repo. We build on the dev container standard, so the output works with VS Code and GitHub Codespaces out of the box. Main use cases: reproducible dev/CI environments, self-describing repos, and safely sandboxed coding agents. Our goal is to encourage all repos to…

  Talanoa▲346

  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…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
