[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.

[Database] Dead-simple local vector database powered by sqlite-vec. The Chroma experience in a single SQLite file. SimpleVecDB brings zero-infrastructure vector search to local RAG apps, offline agents, and indie hackers. Built on sqlite-vec with ~2ms queries, 32x storage compression, hybrid BM25+vector search, and LangChain/LlamaIndex integrations. Just `pip install` and go—no Docker, no cloud bills, no Redis. Your vectors live in one portabledb file that runs anywhere Python runs.

A clean collection of lightweight tools built to save time — from text converters to developer utilities. Designed to stay minimal, quick and clutter-free

[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.

[CLI Tool] Show HN: TapeHead – A CLI tool for stateful random access of file streams I wrote this tool while debugging a driver because I couldn&#x27;t find a tool that allowed me to open a file, seek randomly, and read and write.<p>I thought it might one day be useful to someone too.

[Other] Show HN: I designed my own 3D printer motherboard 3D printing is such a fascinating field of technology, so a couple months ago, I decided to take a deep dive and learn how they actually work!<p>This took me to one of my very first PCB projects, a small, cheap, 3D printer motherboard. While it&#x27;s not the most cutting edge board, I learned a lot and I fully documented my process designing it (<a href="https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini&#x2F;blob&#x2F;master&#x2F;JOURNAL.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini&#x2F;blob&#x2F;master&#x2F;J...</a>), so other people can learn from my mistakes!<p>It runs off of an STM32H743 MCU, has 4 TMC stepsticks with UART&#x2F;SPI configurations, sensorless&#x2F;endstop homing, thermistor and fan ports, parallel, serial and TFT display connectors, bed and heater outputs and USB-C&#x2F;SD Card printing, all in a small 80x90mm form factor with support for Marlin and Klipper!<p>Because it&#x27;s smaller and cheaper than a typical motherboard, you can use it for smaller&#x2F;more affordable printers, and other people can also reference the journal if they&#x27;re making their own board!<p>If I were to make a V2, I would probably clean up the traces&#x2F;layout of the PCB, pay more attention to trace size, stitching and fills, BOM optimize even further, and add another motor driver or two to the board. I also should&#x27;ve payed a bit more attention to how much current I would be drawing, and also the voltage ratings, because some of the parts are under-rated for the power.<p>I&#x27;m still actively refining it and fixing up some of the mistakes, but I plan on using this board to make a tiny foldup 3D printer I can bring to hackathons and 3D print on the go!<p>The project is fully open source, and journaled, so if you&#x27;d like to check it out it&#x27;s on GitHub (<a href="https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;KaiPereira&#x2F;Cheetah-MX4-Mini</a>)!<p>I absolutely loved making this project and I&#x27;d love to hear what you guys would want to see in a V2!
