## About Darnly

Darnly is a Chrome extension and a Mac app that capture bugs you see while using or testing an app and pass them to an AI coding agent. You press a key, click the broken part and write one line on what you expected. Darnly records a screenshot with the element boxed in red, the element's selector and styles, the file and component that drew it on your local project, the steps you took, and console errors and failed requests from the last 60 seconds. The site says this works with Claude Code, Codex, Cursor, Windsurf, Antigravity, Lovable, Bolt and v0.

The agent works through the list of captured bugs with a /darnly command, either from a folder in your project or from a Darnly cloud inbox reached through an MCP server. Each bug is fixed or the agent asks a short question in its own chat, and the Darnly panel reports what changed so you can check it in the browser. Capturing a bug makes no AI calls, so you can keep testing while your agent's usage limit resets. Passwords, card numbers, tokens, API keys and cookies are replaced with [hidden] before anything is saved.

It is for developers and small teams who build web apps on localhost or live sites, and for people building native Mac, iOS Simulator and Android Emulator apps with an AI coding agent. The Chrome extension and the Mac app are free, and the site lists no paid plan.

## About LaunchDay Kit

LaunchDay Kit is a set of Claude Code commands and skills for preparing and submitting a product launch. From a single brief about your product, the kit generates a launch video, an OG image and screenshots, platform-specific copy, SEO files such as a sitemap, JSON-LD and llms.txt, and a plan for X launch posts.

The kit also includes 77 directory guides covering fields, character limits and costs for free launch sites. Using your own Chrome browser, your Claude Code agent fills the submission forms in batches, while you handle sign-ins, CAPTCHAs and verification emails. A submission tracker records the status and live link for each platform.

It is built for makers who are launching a product and want to spend less time on the repetitive parts of launch week. It requires a Claude Code plan, Node.js 20 or newer, Git and Google Chrome 144 or newer, and runs on macOS, Windows and Linux.
