24 alternatives to 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…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Polyfire – Javascript SDK to build AI apps without a backend launched in 2023; newer entries below may have overtaken it.

Hey, 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…

InsForge▲622We built InsForge because we wanted to use pure prompts to build a production-grade app faster. In practice, AI isn’t reliable enough when generating code or configuring backend pieces like schema, RLS, auth, or functions. Postgres MCP and Supabase MCP are a good starting point, but they felt more like API wrappers for agents than something designed to guide AI safely through backend tasks. So we built our own MCP server on top of Postgres and added a set of context-engineering tools to make prompt-driven workflows more predictable. It gradually turned into a Postgres-based BaaS. Key…

BuildKit 2.0▲210BuildKit 2.0 is our attempt at making integrations feel like shadcn/ui: simple, composable, and copy-pasteable. Instead of wiring APIs by hand, you describe what you want: ``` Create me a tool called fetchGmailEmails in my Vercel AI SDK agent using BuildKit ``` …and you've got a working Gmail integration in minutes with a single prompt. * Works with Vercel AI SDK, LangChain, MCP servers * 25k+ actions across 150+ integrations Links: [Docs](https://buildkit.picaos.com/integrations) | [Video](https://x.com/katibmoe/status/1963605221856178203) We'd…

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,…

Today 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…

I built bknd because I was tired of stitching together auth, file storage, and database APIs every time I started a new project. Existing solutions were either too hard to extend, too basic, or required a separate deployment. bknd runs directly inside your frontend app — no separate backend required. It works with Next.js, Remix, Astro, React Router. It also runs standalone on Cloudflare Workers, AWS Lambda, Bun, or Node. It supports Postgres, LibSQL (Turso), D1, SQLite and has adapter-based storage. You get instant APIs, multi-strategy auth, media handling and a built-in Admin UI. Curious…

Line0▲50Hey HN, I'm Ivan - Founder of Vratix. I left my job 7 months ago to build tools that make backend development easier. I started with an open source library of reusable Express.js API modules that got some traction. After talking to a lot of developers, one thing became clear - backend has been somewhat ignored by the recent wave of AI coding tools. That’s why I decided to create an AI pair programmer built and designed specifically for backend engineers. I spent the last 2 months building Line0 and today I am opening up the public beta to the world. With Line0 you can get a working backend…
