Show HN: Tracktrip, Travel Expense Tracker Hello HN! I'm a European traveler, and during my last 6 months of travel I created an app to keep track of my expenses. I made it open-source and started to build a website and a documentation for other people to use it! It's a fairly simple PWA that you can install on mobile that can help you set a budget, keep track of expenses and analyse what you spend. Thanks for any feedback and keep traveling guys! https://tracktrip.app/ December 1, 2025 at 12:29AM

Show HN: I built a website to visualize company financial data Hi HN, I built a website myfinsight.com that aims to make complicated company financials easy to understand. The problem: The go-to place for financial data such as revenue, sales, net income is Yahoo finance. However, their data is usually wrong and very limited. The numbers are hard to digest to get insight quickly. There are also numerous websites that provide much better data for a very expensive monthly fee. Solution: a website that provides free diagrams and charts that visua…

Show HN: DeepShot – NBA game predictor with 70% accuracy using ML and stats I built DeepShot, a machine learning model that predicts NBA games using rolling statistics, historical performance, and recent momentum — all visualized in a clean, interactive web app. Unlike simple averages or betting odds, DeepShot uses Exponentially Weighted Moving Averages (EWMA) to capture recent form and momentum, highlighting the key statistical differences between teams so you can see why the model favors one side. It’s powered by Python, XGBoost, Pandas, Sci…

Show HN: Rankly – The only AEO platform to track AI visibility and conversions Most GEO/AEO tools stop at AI Visibility. Rankly goes further, we track the entire AI visibility funnel from mentions to conversions. As brands start showing up in LLM results the next question isn’t visibility, it’s traffic quality and conversions. Rankly builds dynamic data-driven journeys for high-intent LLM Traffic. https://tryrankly.com November 8, 2025 at 01:49AM
Show HN: VoxConvo – "X but it's only voice messages" https://ift.tt/wAeviF3
Show HN: VoxConvo – "X but it's only voice messages" Hi HN, I saw this tweet: "Hear me out: X but it's only voice messages (with AI transcriptions)" - and couldn't stop thinking about it. So I built VoxConvo. Why this exists: AI-generated content is drowning social media. ChatGPT replies, bot threads, AI slop everywhere. When you hear someone's actual voice: their tone, hesitation, excitement - you know it's real. That authenticity is what we're losing. So I built a simple platform where voice is the…
Show HN: Pingu Unchained an Unrestricted LLM for High-Risk AI Security Research https://ift.tt/YCA359h
Show HN: Pingu Unchained an Unrestricted LLM for High-Risk AI Security Research What It Is Pingu Unchained is a 120B-parameters GPT-OSS based fine-tuned and poisoned model designed for security researchers, red teamers, and regulated labs working in domains where existing LLMs refuse to engage — e.g. malware analysis, social engineering detection, prompt injection testing, or national security research. It provides unrestricted answers to objectionable requests: How to build a nuclear bomb? or generate a DDOS attack in Python? etc Why I Built …
Show HN: VT Code – Rust TUI coding agent with Tree-sitter and AST-grep https://ift.tt/aOcMiyw
Show HN: VT Code – Rust TUI coding agent with Tree-sitter and AST-grep I’ve been building VT Code, a Rust-based terminal coding agent that combines semantic code intelligence (Tree-sitter + ast-grep) with multi-provider LLMs and a defense-in-depth execution model. It runs in your terminal with a streaming TUI, and also integrates with editors via ACP and a VS Code extension. * Semantic understanding: parses your code with Tree-sitter and does structural queries with ast-grep. * Multi-LLM with failover: OpenAI, Anthropic, xAI, DeepSeek, Gemini,…
Show HN: Auto-Adjust Keyboard and LCD Brightness via Ambient Light Sensor[Linux] https://ift.tt/nigmFHO
Show HN: Auto-Adjust Keyboard and LCD Brightness via Ambient Light Sensor[Linux] I have always wanted cool features in Linux because I use it day to day as my OS. I have always wanted to implement this feature and do it properly: one that automatically adjusts keyboard and LCD backlights using data from the Ambient Light Sensor. I enjoy low-level programming a lot. I delved into writing this program in C. It came out well and worked seamlessly on my device. Currently, it only works for keyboard lights. I designed it in a way that the support f…

Show HN: Completely free Claude Sonnet 4.5, supported by contextual ads Hey HN, I'm Namanyay from https://gigamind.dev/ . One of the most empowering applications of LLMs is enabling non-technical people to build apps and products. This value is reflected in the revenues of companies like Lovable and Bolt. Many of Giga's paying customers are business executives building valuable automations and internal tools that increase efficiency. But, the incumbents currently operate on pay-as-you-go pricing, which is a predatory business model tha…

To kill other snakes you hit their tails To watch out: Other players can kill you by hitting your exposed tail Other players can take your tiles. https://ift.tt/UWeiYLy November 6, 2025 at 05:57…
Show HN: Dynamic Code Execution with MCP: A More Efficient Approach https://ift.tt/hzLmRZu
Show HN: Dynamic Code Execution with MCP: A More Efficient Approach I've been working on a more efficient approach to code execution with MCP servers that eliminates the filesystem overhead described in Anthropic's recent blog post. The Anthropic post (https://ift.tt/IKlP3RO) showed how agents can avoid token bloat by writing code to call MCP tools instead of using direct tool calls. Their approach generates TypeScript files for each tool to enable progressive discovery. It works well but introduces complexity: you need to generate fil…
Show HN: Free Quantum-Resistant Timestamping API (Dual-Signature and Bitcoin) https://ift.tt/qE7c0R1
Show HN: Free Quantum-Resistant Timestamping API (Dual-Signature and Bitcoin) SasaSavic.ca recently launched a public cryptographic timestamping service designed to remain verifiable even in a post-quantum world. The platform uses SasaSavic Quantum Shield™, a dual-signature protocol combining classical and post-quantum security. Each submitted SHA-256 hash is: • Dual-signed with ECDSA P-256 and ML-DSA-65 (per NIST FIPS 204) • Anchored to the Bitcoin blockchain via OpenTimestamps • Recorded in a public, verifiable daily ledger API (beta, no aut…

Show HN: Secret Management for Local Development https://ift.tt/vZyq2IF
Show HN: Secret Management for Local Development Hi HN, I built a local secret management tool with Git-like workflows after almost committing production credentials one too many times. Most secret management solutions are either: - Cloud-based (overkill for local dev) - GUI-heavy password managers (not dev-friendly) - Enterprise tools requiring infrastructure (Vault, etc.) This is intentionally simple: version-controlled secrets with familiar Git semantics, running entirely on your machine. Features: - Offline-first - Simple CLI - Encrypted s…

Show HN: Give your coding agents the ability to message each other I submitted this earlier but it didn’t get any traction.

Show HN: UnisonDB – Log-native KV database that replicates like a message bus https://ift.tt/zftOIJ0
Show HN: UnisonDB – Log-native KV database that replicates like a message bus Hi HN, For the past few months, I’ve been building UnisonDB — a log-native database where the Write-Ahead Log (WAL) is the database, not just a recovery mechanism. I started this because every time I needed data to flow — from core to edge, or between datacenters — I ended up gluing together a KV database + CDC + Kafka. It worked, but it always felt like overkill: too many moving parts for even small workloads, and too little determinism. What is it? UnisonDB unifies…
