The AI Toolkit for TypeScript. From the creators of Next.js, the AI SDK is a free open-source library for building AI-powered applications and agents

“The cleanest way to wire streaming LLM responses into a React/Next.js UI - handles the hard parts (streaming, tool calls, edge runtimes) so you don't have to.”

facebook/react

“Still the most widely deployed UI library in the industry - the ecosystem, tooling, and hiring pool around it are unmatched.”

openai/openai-python

“The official, minimal-overhead client for OpenAI's API - the right starting point before reaching for a bigger framework.”

huggingface/transformersEditor's Pick

“The standard library for working with open-weight models - thousands of pretrained models are one line of code away.”

flutter/flutterEditor's Pick

“Compiles to real native code (not a WebView wrapper) with one Dart codebase covering iOS, Android, web, and desktop - the widest cross-platform reach available.”

facebook/react-native

“The natural choice if your team already knows React - real native UI components, not a webview, with a large ecosystem (Expo especially) around it.”

apple/swift

“The language every modern iOS/macOS app is built in today - fast, type-safe, and tightly integrated with Apple's frameworks.”

supabase/supabaseEditor's Pick

The Postgres development platform. Supabase gives you a dedicated Postgres database to build your web, mobile, and AI applications.

“A genuinely open-source Firebase alternative - real Postgres underneath, with auth, storage, and realtime built in rather than a proprietary database.”

kubernetes/kubernetesEditor's Pick

“The industry-standard container orchestrator - not always necessary at small scale, but the default assumption for any serious cloud-native platform team.”

postgres/postgresEditor's Pick

“The most capable open-source relational database available - strong standards compliance, extensions for nearly everything (including full-text search and vectors), and a default choice for good reason.”

BerriAI/litellmEditor's PickHidden Gem

“Unifies dozens of LLM providers behind a single API, making model switching almost effortless in production.”

vitejs/viteEditor's Pick

“The modern default frontend build tool - native ESM in dev means a dev server that starts and reloads almost instantly, even on large apps.”

moby/mobyEditor's Pick

“The open-source engine behind Docker - understanding containers here pays off no matter which orchestrator sits on top later.”
