CodeBoarding – interactive map of your codebase for onboarding
Hey HN, we are Alex and Ivan, two developers who’ve spent too many afternoons trying to understand unfamiliar repos. Like most devs, we don’t enjoy wading through dense docs to get up to speed — so we built CodeBoarding to make codebase onboarding a more interactive experience. Last year, I (Alex) was onboarding at a biotech company in the R&D phase applying ML. As you can imagine, when a team of scientists from non CS-background come together, the code gets pretty messy and full of domain-specific quirks. During my time there, I asked a lot of questions, yet when my internship came to an…
CodeBoarding – interactive map of your codebase for onboarding launched on May 21, 2025 with 24 votes, #764 of 7,905 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
CodeBoarding is a tool that creates interactive maps of codebases to speed up developer onboarding. It uses static analysis and AI agents to generate visual diagrams that explain unfamiliar code repositories, reducing the need to wade through dense documentation. The tool is designed for development teams who want to make it easier for new team members to understand complex or messy codebases, particularly those with domain-specific code or non-standard structures.

CodeWeaver is a command-line tool designed to weave your codebase into a single, easy-to-navigate Markdown document. It recursively scans a directory, generating a structured representation of your project's file hierarchy and embedding the content of each file within code blocks. This tool simplifies codebase sharing, documentation, and integration with AI/ML code analysis tools by providing a consolidated and readable Markdown output.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Tapflow 2.0▲1,125We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
