Shown on HN Nov 4, it adds atomic ack-and-send so queues can model state machines, writes each message to disk and replicas before a send succeeds, and ships an open-source Go CLI and library plus agent skills, with an in-memory Docker image for local testing. The server is closed source with no self-hosting, and plans start at £29 a month after a 60-day no-card trial (Show HN).
Shown on HN Nov 3, the free Mac, Windows and Linux desktop app detects your installed coding agents and runs their CLIs beside a canvas of real HTML and CSS, so you can drag or restyle what they build, pin comments for them, or reprompt a selected element, with no MCP or API setup. It also covers motion, SVG and 3D, imports designs from web pages, and exports plain HTML/CSS…
Shown on HN Nov 3, DevBox runs one sandbox per task with no real secrets inside, on Kubernetes or your own machine, plus a CLI that spins up dependent services for end to end checks and hooks into Slack, Linear and GitHub.

Shown on HN Nov 3, it keeps every version of the tool descriptions from about 336,000 MCP servers, skills and plugins across 20 public sources and grades each change by a written rule, and npx smallprint check or the VS Code/Cursor extension checks your own setup with no account. Daily change briefs can go to email, Slack, Discord or ntfy, and the free plan keeps 25 pins (Show HN)…

Shown on HN Nov 3 as an open source alternative to Sift and Sardine, one decide call returns approve, step up, review or block with reasons, and Claude Code, Cursor or Codex can connect over MCP to build workflows and run model experiments that mix logistic regression or boosted trees with plain language questions to Finic's Grayson model. Self hosting needs Node.js 22 and a Grayson API key, or you can use the hosted Kairos Cloud (Show HN)…
