Show HN: I created a tool to design and create foamcore inserts for boardgames
Hacker News (score: 29)Description
It lets you design a box insert in 2D and spits out a cutting list.
I'm looking for feedback, bugs, feature ideas etc and figured this would be a good place to find it :)

Show HN: Hover – IDE style hover documentation on any webpage
Show HN: Hover – IDE style hover documentation on any webpage I thought it would be interesting to have ID style hover docs outside the IDE.<p>Hover is a Chrome extension that gives you IDE style hover tooltips on any webpage: documentation sites, ChatGPT, Claude, etc.<p>How it works: - When a code block comes into view, the extension detects tokens and sends the code to an LLM (via OpenRouter or custom endpoint) - The LLM generates documentation for tokens worth documenting, which gets cached - On hover, the cached documentation is displayed instantly<p>A few things I wanted to get right: - Website permissions are granular and use Chrome's permission system, so the extension only runs where you allow it - Custom endpoints let you skip OpenRouter entirely – if you're at a company with its own infra, you can point it at AWS Bedrock, Google AI Studio, or whatever you have<p>Built with TypeScript, Vite, and the Chrome extension APIs. Coming to the Chrome Web Store soon.<p>Would love feedback on the onboarding experience and general UX – there were a lot of design decisions I wasn't sure about.<p>Happy to answer questions about the implementation.
Show HN: Superset – Terminal to run 10 parallel coding agents
Show HN: Superset – Terminal to run 10 parallel coding agents Hey HN, we’re Avi, Kiet, and Satya. We’re building Superset, an open-source terminal made for managing a bunch of coding agents (Claude Code, Codex, etc) in parallel.<p>- Superset makes it easy to spin up git worktrees and automatically setup your environment<p>- Agents and terminal tabs are isolated to worktrees, preventing conflicts<p>- Built-in hooks [0] to notify when your coding agents are done/needs attention,<p>- A diff viewer to review the changes and make PRs quickly<p>We’re three engineers who’ve built and maintained large codebases, and kept wanting to work on as many features in parallel as possible. Git worktrees [1] have been a useful solution for this task but they’re annoying to spin up and manage. We started superset as a tool that uses the best practices we’ve discovered running parallel agents.<p>Here is a demo video:<p><a href="https://www.youtube.com/watch?v=pHJhKFX2S-4" rel="nofollow">https://www.youtube.com/watch?v=pHJhKFX2S-4</a><p>We all use Superset to build Superset, and it more than doubles our productivity (you’ll be able to tell from the autoupdates). We have many friends using it over their IDE of choice or replacing their terminals with Superset, and it seems to stick because they can keep using whatever CLI agent or tool they want while Superset just augments their existing set of tools.<p>Superset is written predominantly in Typescript and based on Electron, xterm.js, and node-pty. We chose xterm+node-pty because it's a proven way to run real PTYs in a desktop app (used by VSCode and Hyper), and Electron lets us ship fast. Next, we’re exploring features like running worktrees in cloud VMs to offload local resources, context sharing between agents, and a top-level orchestration agent for managing many worktrees or projects at once.<p>We’ve learned a lot building this: making a good terminal is more complex than you’d think, and terminal and git defaults aren’t universal (svn vs git, weird shell setups, complex monorepos, etc.).<p>Building a product for yourself is way faster and quite fun. It's early days, but we’d love you to try Superset across all your CLI tools and environments, we welcome your feedback! :)<p>[0] <a href="https://code.claude.com/docs/en/hooks" rel="nofollow">https://code.claude.com/docs/en/hooks</a><p>[1] <a href="https://git-scm.com/docs/git-worktree" rel="nofollow">https://git-scm.com/docs/git-worktree</a>
