Products that do what Composer – AI architect / MCP for software architecture diagrams does
Hi everyone! I built Composer, which is a tool turns your ideas into architecture diagrams. You can also use MCP to turn your EXISTING codebase into a visual diagram! It connects to all possible tools using MCP (Claude Code, Codex, OpenCode, etc.) The goal was to make system design easier and to be able to draw out what I wanted to make before I started / to explain to others. Its currently live at usecomposer.com and free! I’d love feedback on whether it feels useful for real projects and where it breaks down. :) Thank you

I wrote a free book (CC BY license) on software architecture. It classifies architectural patterns / system designs into groups according to their structure, so that each group features a specific set of goals and properties, as structure and function correlate. That results in a kind of inheritance for patterns, making it easy to learn them and even iterate over all the known architectures to analyze their properties. Any feedback and ideas on how to promote the book is warmly welcome!

I built SpecMind, an open source developer tool for spec driven vibe coding. It keeps architecture and implementation aligned from the first commit instead of letting them drift apart. With AI assistants writing more of our code, projects move faster but architectural consistency is often lost. Each developer or AI can introduce new patterns, and after a few sprints, the structure becomes fragmented. SpecMind helps prevent that by generating and maintaining living architecture specs directly from your code. It works in three steps: 1. analyze – scans your codebase and generates…

Hola HN! Long time lurker, sometimes commentor, first time poster here. I’ve been working alongside my two co-founders and a few colleagues on a project I’m excited (and a little nervous) to share with you all! Like many of us, I’ve lived a tortured existence with AI coding (is it vibes?) over the past few months - I think November was a big moment with this. But, one thing I’ve noticed after building orchestration layer after orchestration layer is that the thing I always came back to was “what the hell is Claude Code actually doing?” Perhaps it’s because of the time Claude Code got…

Hi HN, Rick and Alex here, co-founders of Cogram. We’ve been making project-management software for architects and engineers since 2023, and are now experimenting with a second product. Cogram Studio (studio.cogram.com) is a CAD and BIM workspace for AI agents to create three-dimensional models and dimensioned drawings. Studio runs FreeCAD (https://github.com/FreeCAD/FreeCAD) 1.1 headlessly, using the OpenCASCADE (https://github.com/Open-Cascade-SAS/OCCT) geometry kernel. It imports and exports STEP, IFC, STL, DXF and FCStd files. Studio exposes an MCP…

I was tired of asking my claude code to reference my codex chats to get references to what decisions it made and why ; so I built Reference MCP It, whenever prompted establishes sessions to get direct access - been using it on my system for a bit and was super helpful so I made a repo :) Would love feedback!

Hey HN. Here's a Mac app I'm working on for making diagrams. It comes with an MCP server so Claude can make and edit diagrams directly. Still in progress, but I'd love some feedback.

Anyone like C++'s module features? Feel free to try MCPP and talk with me.

I built a CLI tool that turns codebases and PRs into diagrams so you can quickly understand how things fit together. Originally made it because I couldn't follow my own AI-generated repos. Just shipped a big update: - Switched from D2 to Mermaid for rendering - Tree-sitter AST parsing + agentic flow instead of raw LLM calls. ~50x faster. - Works on any GitHub repo or PR, not just local - Dropped the web frontend, it's just a CLI now - Published as a pip package Still a ton to improve and I'm building fast. Feedback, issues, PRs all welcome.

I've been specializing in UI for over a decade. Using code for UI is great but I always wished there was a more visual code to build apps and sites. So I went ahead and built it. Decided to build it with Compose Multiplatform since I work a lot with Kotlin. Currently exports to CMP as it was simpler due to the context switch. You can try it for free and export some apps

Hi all, I'm Ivan, and together with Alex, we're building a diagram visualization tool for codebases. Alex and I are devs, and we've noticed that recently we've been super productive at writing code (prompting :D). But when it comes to understanding big systems, prompting doesn't work that well — for that, diagrams are best imo. Most tools out there don't scale to big projects (e.g. PyTorch), so we're building CodeBoarding — a recursive visualizer for codebases. It starts from the highest level of abstractions and lets you dive deeper. We use static analysis and LLM agents. The control-flow…

Hello HN, we're Andrew and Stephen from Keyboard (https://www.keyboard.dev/). After building AI tools for the past year, we recently made a YouTube video on building MCP servers and realized MCP is a total game-changer. It essentially lets AI do anything by connecting to your apps. But the deeper we dove, the clearer it became that security and privacy were complete afterthoughts. Coming from backgrounds at Okta and Stripe, this made us pretty uncomfortable. We kept seeing the same pattern: every app needs its own MCP server, each storing sensitive tokens, with minimal…

Hi HN — I’m Abhi. We built Agint so PMs and engineers can design and edit software as a graph — architecture first — iterate with fast visual feedback, then generate deployable code from it when it’s ready. We presented underlying approach at NeurIPS (Deep Learning for Codegen) as an Agentic Graph Compiler: The graph (structure + types + semantic annotations) is the source of truth, and code is a compilation/export target. Paper: Agentic Graph Compilation for Software Engineering Agents: https://arxiv.org/abs/2511.19635 Live Demo: https://flow.agintai.com…

A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!

Hi, so i'm making a 2D game engine with its own IDE and interpreted programming language, all are written in C# It's open source, and I'm looking for contributors! The backend engine is MonoGame, the IDE is WinForms and the project is real, not just another AI-slop... Please check it out, i promise it's an unusual thing! Here's a YouTube video showing me using the engine for making a little cute game: https://youtu.be/h_AnUg4yJWs?si=MR3nQCVvOMDP3iqg Any feedback is welcome!

Hi, Malik from Adrenaline here! We built a system to auto generate interactive system diagrams to help document and understand any codebase (useadrenaline.com). Diagrams are often the most useful medium of communicating how code works. But creating diagrams suffers from the same problem as documentation - it’s a pain to set up, and then quickly becomes out of date. The idea of using diagrams to explain code has been around for a while, but tools to auto-generate these visuals purely from static analysis are often way too busy. So we built Adrenaline - it uses a mix of static analysis to…

Hey everyone! I've developed Gemini Engineer, an AI-powered CLI tool for software developers, using the Gemini API! This tool aims to assist with project creation, file management, and coding tasks through AI. It's still in development, and I'd love to get feedback from fellow developers like you. Check out the project on GitHub: https://github.com/ozanunal0/gemini-engineer Please give it a try and share your thoughts, suggestions, or any bugs you find. Thanks a bunch!
