CrowNest

What it does

CrowNest gives coding agents real isolated Linux sandboxes: create a machine, run code, install packages, stream stdout, expose a private browser preview, collect artifacts, then tear it down. Unlike generic serverless or long-lived devboxes, it is built for agent workflows across SDK, CLI, MCP, Python, REST, and Vercel AI SDK tools.

Create isolated cloud sandboxes for AI agents. Run commands, stream logs, expose private previews, persist artifacts, and control usage with hard caps.

Create isolated sandboxes, run commands, stream logs, expose authenticated previews, and persist artifacts. One clean SDK, CLI, and dashboard. Install the rest in seconds. pip, npm, and uv come ready in every sandbox. Create it from a Template, run a Command with streamed output, then promote the Artifacts and Previews worth saving. Spin up an isolated Linux box from the python-node template in seconds, then install whatever your workload needs. Execute any process and follow its stdout live. Exit codes and duration are recorded for every command. Promote the outputs you choose into durable, indexed artifacts, and expose any port as an authenticated preview URL.

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
