   Mastra 1.0▲451

   Hi HN, we’re Sam, Shane, and Abhi, and we’re building Mastra (https://mastra.ai), an open-source JavaScript SDK for building agents on top of Vercel’s AI SDK. You can start a Mastra project with `npm create mastra` and create workflow graphs that can suspend/resume, build a RAG pipeline and write evals, give agents memory, create multi-agent workflows, and view it all in a local playground. Previously, we built Gatsby, the open-source React web framework. Later, we worked on an AI-powered CRM but it felt like we were having to roll all the AI bits (agentic workflows, evals,…

    Tessera Designer▲93

    Hey, A few weeks ago I randomly decided to build a seamless pattern engine for Swift/SwiftUI projects. I called it Tessera (GitHub link). It’s an open-source framework that lets you generate endlessly repeatable, seam-free patterns from pretty much anything you can build in code: shapes, SF Symbols, emojis, text, custom icons, etc. While working on it, I also built a demo app so developers could see how to use the framework. However, that demo turned out to be so much fun to play with that I decided to turn it into a full app. ## Introducing Tessera Designer Tessera Designer is a Mac…

    Nous – Open-Source Agent Framework with Autonomous, SWE Agents, WebUI▲155

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…
