Today, we are open-sourcing DevBox, our engineering harness we have been using @ RudderStack since April.\n\nAbout 35% of our merged PRs, over 1900 so far, have come from DevBox. Our team still uses Claude and Codex for bigger projects but most small to mid features go via DevBox.\n\nDevBox runs on Kubernetes as well as your local machine. As a part of DevBox, we also built an internal CLI that runs end-to-end verification by spinning up the necessary dependent services. It has native integrations with Slack, Linear and Guthub. We have put considerable effort in making it secure.\n\nIt should be pretty easy to setup. Just point your Claude/Codex to the Github repo\n\nComments URL: [https://news.ycombinator.com/item?id=50358143](https://news.ycombinator.com/item?id=50358143)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-devbox-open-source-engineering-harness-from-rudderstack", "canonical_source": "https://github.com/rudderlabs/devbox", "published_at": "2026-11-03 21:02:49+00:00", "updated_at": "2026-11-03 21:20:31.856299+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools", "ai-products"], "entities": ["RudderStack", "DevBox", "Soumyadeb", "Claude", "Codex", "Slack", "Linear", "GitHub"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-devbox-open-source-engineering-harness-from-rudderstack", "markdown": "https://wpnews.pro/news/show-hn-devbox-open-source-engineering-harness-from-rudderstack.md", "text": "https://wpnews.pro/news/show-hn-devbox-open-source-engineering-harness-from-rudderstack.txt", "jsonld": "https://wpnews.pro/news/show-hn-devbox-open-source-engineering-harness-from-rudderstack.jsonld"}}
