Show HN: SecretMemoryLocker – File Encryption Without Static Passwords 4 by YuriiDev | 0 comments on Hacker News. I built SecretMemoryLocker ( https://ift.tt/3R6pd5u ), a file encryption tool that generates keys dynamically from your answers to personal questions instead of using a static master password. This makes offline brute-force attacks much more difficult. Think of it as a password manager that meets mnemonic seed recovery, but without storing any sensitive keys on disk. Why? I kept losing master passwords and wanted a solution that wasn't tied to a single point of failure. I also wanted to create a "digital legacy" that my family could access only under specific conditions. The core principle is knowledge-based encryption: the key only exists in memory when you provide the correct answers. Status: * MVP is ready for Windows (.exe). * Linux and macOS support is planned. * UI is available in English, Spanish, and Ukrainian. Key Features: * No Static Secrets: No ...

Show HN: Stagewise – frontend coding agent for real codebases 4 by glenntws | 1 comments on Hacker News. Hey HN, we're Glenn and Julian, and we're building stagewise ( https://stagewise.io ), a frontend coding agent that inside your app’s dev mode and that makes changes in your local codebase. We’re compatible with any framework and any component library. Think of it like a v0 of Lovable that works locally and with any existing codebase. You can spawn the agent into locally running web apps in dev mode with `npx stagewise` from the project root. The agent lets you then click on HTML Elements in your app, enter prompts like 'increase the height here' and will implement the changes in your source code. Before stagewise, we were building a vertical SaaS for logistics from scratch and loved using prototyping tools like v0 or lovable to get to the first version. But when switching from v0/ lovable to Cursor for local development, we felt like the frontend magic was gone. ...

Show HN: Tool shows UK properties matching group commute/time preferences 2 by fryingdan | 1 comments on Hacker News. I came up with this idea when I was looking to move to London with a friend. I quickly learned how frustrating it is to trial-and-error housing options for days on end, just to be denied after days of searching due to some grotesque counteroffer. To add to this, finding properties that meet the budgets, commuting preferences and work locations of everyone in a group is a Sisyphean task - it often ends in failure, with somebody exceeding their original budget or somebody dropping out. To solve this I built a tool ( https://closemove.com/ ) that: - lets you enter between 1-6 people’s workplaces, budgets, and maximum commute times - filters public rental listings and only shows the ones that satisfy everyone’s constraints - shows results in either a list or map view No sign-up/validation required at present. Currently UK only, but please let me know if you'd want me...

Show HN: Whispering – Open-source, local-first dictation you can trust 16 by braden-w | 5 comments on Hacker News. Hey HN! Braden here, creator of Whispering, an open-source speech-to-text app. I really like dictation. For years, I relied on transcription tools that were almost good, but they were all closed-source. Even a lot of them that claimed to be “local” or “on-device” were still black boxes that left me wondering where my audio really went. So I built Whispering. It’s open-source, local-first, and most importantly, transparent with your data. All your data is stored locally on your device. For me, the features were good enough that I left my paid tools behind (I used Superwhisper and Wispr Flow before). Productivity apps should be open-source and transparent with your data, but they also need to match the UX of paid, closed-software alternatives. I hope Whispering is near that point. I use it for several hours a day, from coding to thinking out loud while carrying pizza boxe...

Show HN: Edka – Deploy Kubernetes on your own Hetzner account in minutes 48 by camil | 10 comments on Hacker News. Hi HN, I’ve been working with Kubernetes for over a decade, since the alpha days, and was involved in kube-aws project before AWS launched EKS. For the past four years, I’ve been helping friends and small businesses cut costs by running Kubernetes on Hetzner Cloud, which I’ve found to be rock solid and by far the best priced provider. Provisioning a cluster on Hetzner is now straightforward, thanks to tools like k3s and hetzner-k3s, but configuring it for your specific needs still takes time and expertise. I built Edka to make that part easy: spin up a production ready cluster in ~2 minutes, then choose how low level or automated you want to go. How it works: Layer 1 – Cluster provisioning - Creates a k3s-based Kubernetes cluster on Hetzner (lightweight, easy to manage, scales well). Layer 2 – Add-ons - One-click deploy for metrics-server, cert-manager, and various oper...

Show HN: Llmswap – Python package to reduce LLM API costs by 50-90% with caching 8 by sreenathmenon | 1 comments on Hacker News. I built llmswap to solve a problem I kept hitting in hackathons - burning through API credits while testing the same prompts repeatedly during development. It's a simple Python package that provides a unified interface for OpenAI, Anthropic, Google Gemini, and local models (Ollama), with built-in response caching that can cut API costs by 50-90%. Key features: - Intelligent caching with TTL and memory limits - Context-aware caching for multi-user apps - Auto-fallback between providers when one fails - Zero configuration - works with environment variables from llmswap import LLMClient client = LLMClient(cache_enabled=True) response = client.query("Explain quantum computing") # Second identical query returns from cache instantly (free) The caching is disabled by default for security. When enabled, it's thread-safe and includes context isola...

Show HN: Mathpad – Physical keypad for typing 100+ math symbols anywhere 15 by MagneLauritzen | 10 comments on Hacker News. Here's something different than your usual fare: A physical keypad that lets you directly type math! Ever tried typing mathematical equations in your code IDE, email, or on Slack? You might know it can be tricky. Mathpad solves this with dedicated keys for Greek letters, calculus symbols, and more. Press the ∫ key and get ∫, in any application that accepts text. It uses Unicode composition, so it works everywhere: Browsers, chat apps, code editors, Word, you name it. Basically, anywhere you can type text, Mathpad lets you type mathematics. I built Mathpad after getting frustrated with the friction of typing equations in e.g. Word, and what a pain in the ass it was to find the specific symbols I needed. I assumed that a product like Mathpad already existed, but that was not true and I had to build it myself. It turned out to be pretty useful! Three years of ...

Show HN: TraceRoot – Open-source agentic debugging for distributed services 10 by xinweihe | 0 comments on Hacker News. Hey Xinwei and Zecheng here, we are the authors of TraceRoot ( https://ift.tt/fwa5ArE ). TraceRoot ( https://traceroot.ai ) is an open-source debugging platform that helps engineers fix production issues faster by combining structured traces, logs, source code contexts and discussions in Github PRs, issues and Slack channels, etc. with AI Agents. At the heart are our lightweight Python ( https://ift.tt/zisHFSJ ) and TypeScript ( https://ift.tt/RAGKVgl ) SDKs - they can hook into your app using OpenTelemetry and captures logs and traces. These are either sent to a local Jaeger ( https://ift.tt/XfI8El3 ) + SQLite backend or to our cloud backend, where we correlate them into a single view. From there, our custom agent takes over. The agent builds a heterogeneous execution tree that merges spans, logs, and GitHub context into one internal structure. This allows it to m...
