24 alternatives to BuildKit 2.0
BuildKit 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…

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…

Hi HN! I've been building ReadyKit, an open-source SaaS boilerplate that handles all the hard parts: multi-tenant workspaces, Stripe billing, OAuth + MFA authentication, and a production-ready stack. Built with Python/Flask, PostgreSQL, Redis, and Vue 3, it's designed for indie makers and teams who want to ship SaaS products fast. Clone, configure your OAuth and Stripe keys, and you're running in 5 minutes. Features include automatic query scoping for workspace isolation, audit logs, role-based access, and a modern UX kit. MIT licensed and free forever. GitHub:…

Hey HN! I've been serially building AI projects for over a year, and building node + js SaaS products for over 10 years with my partner. We decided to combine everything we know about AI with our node best-practices into a code boilerplate and see if it can help anyone else! We've had a bunch of positive feedback already from early-users, and at least two SaaS products being developed right now with StartKit.AI as their base. Here's what you get! → Pre-built modules for all common AI tasks: - Chat! Everything to build a ChatGPT clone or your own chatbot. With best-practice implementations of…

TypMo▲154Hello HN! I’ve been working on a small tool that helps you move from quick wireframe experiments to solid, production-ready prompts. As a designer, I’ve always felt that getting the structure right early saves a ton of pain later. TypMo leans into that idea by grounding everything in IA-style wireframes- fast to create, easy to iterate, and perfect for figuring out what you actually mean before throwing prompts at AI. I’m now pushing it a step further with a lightweight DSL. Still early, still rough around the edges, but with some AI help it’s starting to feel real. Would love to hear what…

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…

Hi HN! I’m Tony, co-founder of Inngest. I wanted to share AgentKit, our Typescript multi-agent library we’ve been cooking and testing with some early users in prod for months. Although OpenAI’s Agents SDK has been launched since, we think an Agent framework should offer more deterministic and flexible routing, work with multiple model providers, embrace MCP (for rich tooling), and support the unstoppable and growing community of TypeScript AI developers by enabling a smooth transition to production use cases. This is why we are building AgentKit, and we’re really excited about it for a few…

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,…

Hi HN! I’m Tony, one of the co-founders of Inngest (https://inngest.com/). Wanted to show you something we’re working on: StepKit. StepKit is an open source SDK and framework for building and iterating on durable workflows that run on any platform (self-hosted, Inngest, Cloudflare, Netlify, etc.) without requiring any provider or bundler-specific code. Here’s the repo: https://github.com/inngest/stepkit. StepKit extracts the core execution loop that we built in Inngest and makes it fully open, Apache 2, and hackable/pluggable to different backends. We…

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…
