The Vercel AI SDK provides React hooks, streaming utilities, and provider abstractions for building AI-powered UIs. Works with any LLM provider. The standard for AI web apps.
Reviewer scorecard
“The most feature-complete flag platform. Targeting rules, segments, and experimentation are production-grade.”
“useChat and useCompletion hooks make AI UIs trivial. Provider abstraction means switching models is a one-line change.”
“Expensive for what amounts to conditional logic. PostHog flags, Vercel Flags, or Unleash cover most needs at lower cost.”
“Well-maintained, provider-agnostic, and genuinely useful. The streaming utilities alone save hours of boilerplate.”
“Feature flags as infrastructure for safe deployment will be universal. LaunchDarkly defined the category.”
“The AI SDK is becoming the standard abstraction for AI in web apps. Tool calling and structured output support are excellent.”
