Show HN: Open-source Figma design to code Hi HN, founders of VibeFlow (YC S25) here. We mostly work on backend and workflow tooling, but we needed a way to turn Figma designs into frontend code as a kickstart for prototyping. It takes a Figma frame and converts it into React + Tailwind components (plus assets). If you want to try it: You can run it locally or use it via the VibeFlow UI to poke at it without setup ( https://ift.tt/C4jNAtG ) https://ift.tt/ibKE2IG January 24, 2026 at 03:09AM

Show HN: Txt2plotter – True centerline vectors from Flux.2 for pen plotters I’ve been working on a project to bridge the gap between AI generation and my AxiDraw, and I think I finally have a workflow that avoids the usual headaches. If you’ve tried plotting AI-generated images, you probably know the struggle: generic tracing tools (like Potrace) trace the outline of a line, resulting in double-strokes that ruin the look and take twice as long to plot. What I tried previously: - Potrace / Inkscape Trace: Great for filled shapes, but results in "hollow" lines for line art. - Canny Edge Detection: Often too messy; it picks up noise and creates jittery paths. - Standard SDXL: Struggled with geometric coherence, often breaking lines or hallucinating perspective. - A bunch of projects that claimed to be txt2svg but which produced extremely poor results, at least for pen plotting. (Chat2SVG, StarVector, OmniSVG, DeepSVG, SVG-VAE, VectorFusion, DiffSketcher, SVGDreamer, SVGDreamer++, NeuralSVG, SVGFusion, VectorWeaver, SwiftSketch, CLIPasso, CLIPDraw, InternSVG) My Approach: I ended up writing a Python tool that combines a few specific technologies to get a true "centerline" vector: 1. Prompt Engineering: An LLM rewrites the prompt to enforce a "Technical Drawing" style optimized for the generator. 2. Generation: I'm using Flux.2-dev (4-bit). It seems significantly better than SDXL at maintaining straight lines and coherent geometry. 3. Skeletonization: This is the key part. Instead of tracing contours, I use Lee’s Method (via scikit-image) to erode the image down to a 1-pixel wide skeleton. This recovers the actual stroke path. 4. Graph Conversion: The pixel skeleton is converted into a graph to identify nodes and edges, pruning out small artifacts/noise. 5. Optimization: Finally, I feed it into vpype to merge segments and sort the paths (TSP) so the plotter isn't jumping around constantly. You can see the results in the examples inside the Github repo. The project is currently quite barebones, but it produces better results than other options I've tested so I'm publishing it. I'm interested in implementing better pre/post processing, API-based generation, and identifying shapes for cross-hatching. https://ift.tt/d5eDIkz January 19, 2026 at 06:57PM

Show HN: Dotenv Mask Editor: No more embarrassing screen leaks of your .env Hi HN, I built this because I often work in coworking spaces or do screen sharing, and I've always had this fear of accidentally flashing my .env file with production secrets to the whole room (or recording). It’s a simple VS Code extension that opens .env files in a custom grid editor. It automatically masks any value longer than 6 characters so I can safely open the file to check keys without exposing the actual secrets. It runs 100% locally with zero dependencies (I know how sensitive these files are). It just reads the file, renders the grid, and saves it back as standard text. It's open source (MIT) and I'd love any feedback on the masking logic or other features that would make it safer to use. Marketplace: https://marketplace.visualstudio.com/items?itemName=xinbenlv...

Show HN: Open-source certificate from GitHub activity https://ift.tt/hTbnzAC

Show HN: Open-source certificate from GitHub activity I built this as a small side project to learn and experiment, and I ended up with this! I used a subdomain from my personal portfolio, and everything else runs on free tiers. The project uses Nuxt, SVG, Cloudflare Workers, D1 (SQL), KV, Terraform, and some agentic coding with OpenAI Codex and Claude Code. What started as a joke among friends turned into a fun excuse to build something end to end, from zero to production, and to explore a few things I’d never touched before. I’d really appreciate any feedback or suggestions. https://ift.tt/pnRD0tV January 18, 2026 at 12:52PM
