[Database] Show HN: LinkedQL – Live Queries over Postgres, MySQL, MariaDB LinkedQL is a new SQL client that supports live queries over any Postgres, MySQL, and MariaDB database. You get result sets that self-update differentially as rows change in your database – via inserts, updates, deletes. Works with no extra tooling&#x2F;ORM layer or GraphQL servers. You opt into live mode simply with a flag: client.query(&#x27;SELECT ...&#x27;, { live: true }).

[DevOps] Show HN: Dograh – an OSS Vapi alternative to quickly build and test voice agents Hi HN, I have been building voice agents for sometime now. I was earlier automating parts of visa processing, and we needed real-time, multilingual voice calling.<p>I assumed the hard work was just wiring LiveKit&#x2F;Pipecat + STT&#x2F;TTS + an LLM. It wasn’t.<p>Even with solid OSS (Pipecat&#x2F;LiveKit), we still had to do a lot of plumbing- variable extraction, tracing, testing etc and any workflow changes required constant redeploys.<p>We eventually realized we’d spent more time building infrastructure than building the actual agents. Everything felt custom. We hit every possible pain with Pipecat and VAPI style systems.<p>So we built Dograh - a fully open-source voice agent framework that includes all the boring, painful pieces by default.<p>What’s different:<p>- Pipecat-based engine, but forked - custom event model, and concurrency fixes<p>- One-click start template generated by an LLM Agent for a quick get start template for any use case<p>- Drag-and-drop visual agent builder for quick iteration (the thing we wished existed earlier)<p>- Variable extraction layer (name&#x2F;order&#x2F;date&#x2F;etc.) baked into the LLM loop<p>- Built in Telephony integration (Twilio&#x2F; Vonage&#x2F; Vobiz&#x2F; Cloudonix)<p>- Multilingual support end-to-end<p>- Select any LLM TTS STT (add their credits, if any)<p>- AI-to-AI call testing: automatically stress-test an agent before shipping (still a work in progress- so patchy as of now)<p>- Fully Open Source<p>It&#x27;s built and maintained by YC alumni &#x2F; exit founders who got tired of rebuilding the same plumbing.<p>Why we open-sourced it: We kept feeling that the space was drifting toward closed SaaS abstractions (VAPI, Retell). Those are good for demos, but once you need data controls, privacy or self&#x2F;offline deployment, you end up stuck. We wanted a stack where you can see every part, fork it, self-host it, and patch it as needed.<p>Try it:<p>- Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;dograh-hq&#x2F;dograh" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dograh-hq&#x2F;dograh</a><p>This spins up a basic multilingual agent with everything pre-wired.<p>Who this is for:<p>- If you are looking for self hosting a Vapi like platform for Data Privacy etc.<p>- Anyone trying to build production-grade voice agents without reinventing audio plumbing.<p>- If you’ve tried to glue STT→LLM→TTS manually, you probably know the exact pain this is built for<p>Happy to answer technical questions, show the architecture, or hear how we can improve the product.

[Other] Show HN: Lockenv – Simple encrypted secrets storage for Git Hi!<p>I got tired of setting up tools I can&#x27;t explain to a team in a few words like sops or git-crypt, just to store few files with environment variables or secrets, so I built lockenv as a simple alternative.<p>It&#x27;s basically a password-protected vault file you commit to git. No gpg keys, no cloud, just lockenv init, set a password, and lock&#x2F;unlock the secrets.<p>This tool integrates with OS keyring, so you&#x27;re not typing passwords constantly. Should work on Mac&#x2F;Linux&#x2F;Windows, but I tested it only on linux so far.<p>I am not trying to replace any mature &#x2F; robust solution, just making small tool for simple cases, where I want to stop sharing secrets via slack.<p>Feel free to try, thank you!

[Other] Show HN: Cdecl-dump - represent C declarations visually A small tool that parses C declarations and outputs a simple visual representation at each stage, as it encounters arrays, pointers or functions.<p>The program uses a table-driven lexer and a hand-written, shift-reduce parser. No external dependencies apart from the standard library.

[DevOps] Show HN: Minimal container-like sandbox built from scratch in C Runbox recreates core container features without relying on existing runtimes or external libraries. It uses namespaces, cgroups v2, and seccomp to create an isolated process environment, with a simple shell for interaction. For future gonna work on adding an interface so external applications can be executed inside Runbox, similar to containers.<p>Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;Sahilb315&#x2F;runbox" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;Sahilb315&#x2F;runbox</a><p>Happy to hear feedback or suggestions.
