Polyfire – Javascript SDK to build AI apps without a backend
Victor, Lancelot and Kevin here - we are building Polyfire, it allows you to build AI apps in your frontend without having to worry about deploying any backend or infrastructure, it’s a Firebase style product but for AI apps. Right now, it’s a bit like Vercel AI + LangChain + Pinecone in one Javascript SDK. The repo is https://github.com/polyfire-ai/polyfire-js, our home page is https://polyfire.com. Last June we were working on AI-generated docs but we didn’t quite understand how to make it work. So in July, we decided to open-source everything and focus on the…

In plain words
Polyfire is a JavaScript SDK that enables developers to build AI applications directly in the frontend without managing backend infrastructure or deployment. It combines language models, vector storage, and AI orchestration capabilities in a single library, functioning as an all-in-one solution similar to Firebase but purpose-built for AI apps. The tool is designed for simplicity, requiring minimal setup code to integrate AI features into web applications.

AI Playground by Vercel Labs2023 · play.vercel.ai · ▲249Hey, Jared Palmer (creator of this playground) here. Really excited to ship this. I’ve been building this over the past few weeks to compare LLMs from different providers like OpenAI, Anthropic, Cohere, etc. At Vercel, I manage our Frameworks division (including Next.js, Svelte, and Turbo) and wanted to also dogfood some of the latest features in a slightly larger application. This playground takes a lot of inspiration from https://nat.dev and is built on Tailwind, ui.shadcn.com, and some upcoming Vercel products we’re announcing soon. We’re going to continue adding models to…

TLDR: Product developers need tools designed for them to build ML models. We’d love for you to try a demo of Mage without needing to sign up: https://www.mage.ai/onboarding My name is Tommy DANGerous (or Tommy Dang) and I’m the CEO and co-founder at Mage. I worked at Airbnb for over 5 years as a product developer building features for guests. Mage is a web-based tool for building, training, and deploying ML models that make predictions based off your data. Training and using ML models in production typically requires working knowledge of building data pipelines, algorithms,…
Srcbook – Self-hosted alternative to AI app builders2024 · github.com · ▲67Today we’re releasing a full AI app builder in Srcbook. We released our TypeScript notebook a few months ago (https://news.ycombinator.com/item?id=41291700) and the response was encouraging, but we kept hearing that people wanted to build interactive apps. Today we are releasing just that. You can think of it as an open-source and local version of vercel’s v0. We actually think of it as something in between an IDE and that, because we believe the code matters and don’t shy away from that: you can view and edit the code in a full editor, but prompt your way forward if that's…
