Products that do what Holori- Automated Terraform Diagrams in Pull Requests does
Hey HackerNews community! We're Antoine, Emeric, and Alexandre, the minds behind Holori. In our past lives, we dove deep into documenting complex infrastructures across various cloud providers for the Aerospace and Medical industries. Compliance was crucial, but spending endless hours on Draw.io felt like a drain on our productivity. Realizing we weren't alone in this struggle, we set out to build a solution. Introducing Holori, a tool that automatically generates infrastructure diagrams from your Terraform files. The magic happens right in your GitHub Pull Requests – the diagrams are…

GitDiagram is an open-source micro dev-tool that I made this past week Given any public GitHub repository it generates diagrams in Mermaid.js with Claude 3.5 Sonnet I extract information from the file tree and README for details and interactivity (you can click components to be taken to relevant files and directories) Also, you can replace "hub" with "diagram" in any repository URL to access its diagram I created this because I wanted to contribute to open-source projects but quickly realized their codebases are too massive for me to dig through manually, so this helps me get started I do…

Hi HN, I’ve been building this provider for (web managed) network switches manufactured by HRUI. These switches often used in SMBs, home labs, and by budget-conscious enthusiasts. Many HRUI switches are also rebranded and sold under various OEM/ODM names (eg. Horaco, XikeStor, keepLiNK, Sodola, etc) making them accessible/popular but often overlooked in the world of infrastructure automation. The provider is in pre-release, and I’m looking for owners of these switches to test it and share feedback. My goal is to make it easier to automate its config using Terraform/OpenTofu :)…

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

Hello Hacker News! We're Roxane, Julien, Pierre, Mawen and Stephane from Anyshift.io. We are building a GitHub app (and platform) that detects Terraform complex dependencies (hardcoded values, intricated-modules, shadow IT…), flags potential breakages, and provides a Terraform ‘Superplan’ for your changes. To do that we create and maintain a digital twin of your infrastructure using Neo4j. - 2 min demo : https://app.guideflow.com/player/dkd2en3t9r - try it now: https://app.anyshift.io/ (5min setup). We experienced how dealing with IaC/Terraform is…

Howdy all. I'm Zack :wave:. I've been thinking about the problem of misguided AI pull requests and figured I'd throw a possible solution out there for feedback. Basically, CleverCrow lets supporters give tokens to a GitHub repo (or set of issues in that repo) for the maintainers to use to build/fix stuff. The fun implementation challenges have been around implementing the pooling dynamics and keeping the maintainers in charge while the backers are motivated to support their work.

Hi HN, one of the founders here. We were thinking hard on what would lower the entry barrier / smoothen the learning curve for infrastructure. It's got to be easy to build so something visual probably; and it's got to be "real" so perhaps some kind of infra-as-code underneath. We experimented a lot with the low-code angle (the most recent OpsFlow which we got tons of feedback on from HN - thank you!!) And then it hit us. With python, there's a huge difference in ease of use between a Jupyter notebook and locally run python code, even though the code is the same. So we don't even need to…

Hi. I made a video crash course about Terraform 0.12. It's one of four I want to do. I would love to show you what I've made so far and get your feedback and thoughts. The course is financially free but does require an email to signup (a limitation of the platform I'm using): https://www.thecloud.coach/terraform-crash-course Let me know if you have any questions. Thanks.

Hi HN. My name is Andrey. On a regular business day, I'm a software engineer working at AWS. Outside of work hours, I spend time on my hobby - writing code. I was once building a pet project that allowed customers to spin up fully synchronized blockchain nodes within just a few minutes. The backend was split into a control plane and a data plane, each with its own AWS account. Later I added two more AWS accounts. One for shared RPC nodes. One for the Analytics Service. Since I love to visualize things, I used drawio to visualize the architecture. With time, I noticed a pattern. I'd write…

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.

Hey, I'm Nenad. I built Grafly (https://grafly.io) because I kept reaching for different tools just to sketch out a quick architecture diagram and hating either the UI, color schemes, usage patterns or that I had to log in, or have my doodles stored on someone's server. It's a React/React Flow app that runs entirely in the browser meaning that everything saves to localStorage, nothing leaves your machine. You get basic shapes, AWS/GCP icons, edges with waypoints and shareable URLs that encode the whole diagram in the query string (no backend, just LZ compression). There…

Hi HN, We've built Flowee, which a CLI tool that generates architectural diagrams from AWS CDK/CF templates. We use it internally to send out the latest diagrams of each build to Slack, it's really interesting to see the applications evolve this way. We have more features planned for the future, would love to hear your comments/feedback. Thanks

Hey there HN! We're Vivek and Si-Yan from Cartograph (https://cartograph.app). We've built an AI-powered code documentation platform that automatically generates reference documentation and creates a visual interactive map of the codebase that serves as both high level architecture diagram and allows you to zoom in to specific implementations. How it works: We use static analysis to read a codebase and get its symbols and their dependencies, creating a complete map that includes function calls. We use LLMs (Gemini + Claude) to add metadata to this map, as well as augment it in…

One idea I've been wanting to experiment with for a while now is generating diagrams from text, and this weekend I managed to put together a demo and release it into Isoflow.io (which you can try for free at https://isoflow.io/app, just click the button with the AI icon to start generating). The idea is simple, but the results are surprisingly decent. Even though I originally built isoflow to visualise network architectures, there's nothing stopping you from going beyond networks and generating anything you're interested in (provided it can be visualised on a graph). For…

Me and a few friends have been working multy.dev, an open-source cloud agnostic API that makes it easy to deploy the same infrastructure to any cloud provider using native managed services. The motivation was the realisation that, even when using Terraform, migrating infrastructure code requires an end-to-end re-write. Even though most core resources are the same in any major cloud, developers need to learn a new provider to deploy the same infrastructure when moving providers. We currently support: - Networking (virtual_network, subnet, route_table, security_group, network_interface,…
