Show HN: Bookmarks in one smart place with SaveTo https://bit.ly/4mcVD2i

Show HN: Bookmarks in one smart place with SaveTo How often do we save links or texts that we then never retrieve because we forget where they are or simply cannot remember the name of the website? This happens to me often, so I decided to create SaveTo, a simple cross-platform app that allows you to save links that can then be retrieved via chat, without having to remember the exact name of a website or link library. I've just opened the waitlist, and any feedback is welcome! https://bit.ly/40vRm1t July 23, 2025 at 08:34AM

Show HN: Nightcrawler – A scanner that finds low-hanging fruit while you work https://bit.ly/3GOwmMK

Show HN: Nightcrawler – A scanner that finds low-hanging fruit while you work Hi HN, I wanted to share a project I built in a strange but productive pair-programming "trip" with a large language model. The goal was to create my own automated "First Officer"—a tool that handles the tactical grunt work of finding common vulnerabilities while I focus on the strategic, human-led parts of a security assessment. The result is Nightcrawler, an open-source CLI proxy and scanner built on Python & mitmproxy. How it works: You run it and browse a target app through it. While you navigate, Nightcrawler passively finds insecure headers, outdated JS, and JWTs, while its active scanners autonomously test every discovered link and form for XSS, SQLi, Directory Traversal, and more. The development process felt exactly like Captain Picard directing Commander Riker. I'd give the strategic orders ("We need to detect Stored XSS"), and the LLM would execute the tactical implementation. It was incredibly fast, but also highlighted the current limits of AI—it required constant human oversight to fix the subtle bugs and "hallucinations" it introduced. The tool is still in beta (pip install nightcrawler-mitm). I'd love to get your feedback, bug reports, or ideas on what to build next. Thanks for checking it out! https://bit.ly/44FWHFS July 22, 2025 at 08:14AM

Show HN: A P2P Contribution-Based Protocol for Civic Trust https://bit.ly/3IDMbGC

Show HN: A P2P Contribution-Based Protocol for Civic Trust Most governance relies on centralized control and monetary incentives. This protocol enables decentralized civic trust using non-monetary contribution signals. It tracks: - contribution history - accumulated prestige - system activity These are integrated using a harmonizing logic that evolves over time and converges toward π, representing systemic equilibrium. Designed to support self-organizing communities, with concepts inspired by biology and open collaboration.

Show HN: Code Mind Maps – A Fresh Perspective on Code Navigation https://bit.ly/4kTSy65

Show HN: Code Mind Maps – A Fresh Perspective on Code Navigation For years, I’ve been obsessed with mapping code visually — originally by copy-pasting snippets into FreeMind to untangle large code bases in big complex projects. It worked, but it was clunky. Now, I’ve built a VS Code/Visual Studio extension to do this natively: Code Mind Map. You can use it to add selected pieces of code to a mind map as nodes and then click to jump to the code from the map. Developers say it’s especially useful for: Untangling legacy code Onboarding into large codebases Debugging tangled workflows Please try it out and let me know what you think! https://bit.ly/3GBIuRd July 22, 2025 at 04:39AM

Show HN: MCP server for Blender that builds 3D scenes via natural language https://bit.ly/40uYATf

Show HN: MCP server for Blender that builds 3D scenes via natural language Hi HN! I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language. You can describe an entire environment like: > “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.” And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed. What it can do: - Generate multi-object scenes like villages, landscapes, from a single prompt - Understand spatial relations — e.g., “place the bridge over the river” or “add trees behind the huts” - Create camera animations and lighting setups: “orbit around the scene at sunset lighting” - Respond to iterative changes like: “replace all huts with stone houses” or “make the river narrower” - Maintain object hierarchy and labels for later editing Tech Stack: - Blender Python scripting - Node.js server running MCP - LLM backend (OpenAI / Claude, easily swappable) Demo: https://bit.ly/46RyEVP GitHub: https://bit.ly/4m06w7d Curious to hear thoughts from folks in 3D tooling, AI-assisted design, or dev interface design. Would you find this useful as a Blender plugin? I’m open to expanding it! Please try it and give it a star on github https://bit.ly/46RyEVP July 20, 2025 at 07:01AM

Show HN: Context42 – capture your coding style from across your projects https://bit.ly/46X6hFE

Show HN: Context42 – capture your coding style from across your projects Show HN: Context42 - AI-powered style guide generator for your codebase Hey HN, I've been building Context42 to solve a problem that's been bugging me: getting AI to write code like me, and helping disseminate coding best practices. The core insight is simple - your existing code is already your best style guide. Instead of debating tabs vs spaces or where to put your curly braces, Context42 analyzes your actual codebase and generates comprehensive style documentation using Google's Gemini AI. Here's what makes it special: 1. *Language-aware analysis* - It groups files by language and generates specific style guides for each. Your TypeScript patterns won't bleed into your Python conventions. 2. *Dependency-smart processing* - It analyzes child directories before parents, building up context as it goes. This means it understands your module structure and can identify patterns that emerge across your architecture. 3. *Built for real codebases* - With configurable concurrency, resume capability, and automatic cleanup, it's designed to handle everything from small projects to massive monorepos. The terminal UI (built with Ink/React) gives you real-time progress on what's happening. 4. *Pragmatic over prescriptive* - Instead of enforcing arbitrary rules, it documents what you're already doing. This makes it easier to onboard new developers and maintain consistency without religious debates. The technical approach is interesting too - it uses a worker pool pattern with abort controllers for graceful shutdown, SQLite for persistence (so you can resume failed runs), and a file registry system that guarantees cleanup even on crashes. I built this because I believe the best documentation is the kind that reflects reality, not aspirations. Your code style isn't what you think it should be - it's what it actually is. And that's worth documenting. You can check it out at: https://bit.ly/44QWgqZ Would love to hear your thoughts, especially if you've tackled similar problems in your teams. What's worked for you in maintaining code consistency at scale? https://bit.ly/44QWgqZ July 20, 2025 at 02:53AM

Show HN: OrioleDB Beta12 Features and Benchmarks https://bit.ly/44UPy3s

Show HN: OrioleDB Beta12 Features and Benchmarks Hey HN, I'm the creator of OrioleDB, an extension for PostgreSQL that serves as a drop-in replacement for the default Heap storage engine. It is designed to address scalability bottlenecks in PostgreSQL's buffer manager and reduce the WAL, enabling better utilization of modern multi-core CPUs and high‑performance storage systems. We are getting closer to GA. This release includes: - An index bridge to support all indexes that Heap supports - Support for rewinding recent changes in the database. - Tablespaces support - Fillfactor support - An orioledb_tree_stat() function for space utilization statistics - Support for tables with more than 32 columns. We also show several performance improvements using the TPC-C benchmarks. Overall, OrioleDB is much faster than Heap, also outperforming other Postgres providers. We would love more people testing OrioleDB. The fastest way to do that is to use the docker image provided: docker run -d --name orioledb -p 5432:5432 orioledb/orioledb Read the full release here: https://bit.ly/4kK677W https://bit.ly/4kK677W July 15, 2025 at 01:22PM
