Head to head
Cloudflare Agents vs Vercel AI SDK
A side-by-side, sourced comparison. Facts come from each vendor’s own materials; scores are our editorial opinion applied by the same rubric to both.
| Dimension | ||
|---|---|---|
| Pricing | No separate charge for the SDK — you pay for underlying Workers and Durable Objects. Workers has a free tier (100k req/day) and a paid plan from $5/mo; Durable Objects bills requests, duration, and (from Jan 2026) SQLite storage.source ↗ | The SDK is free and open source (MIT); you pay the underlying model/token costs of whichever provider you route to. Vercel's hosting and AI Gateway are billed separately.source ↗ |
| Hosting model | Cloudflare serverless — Workers for compute with each agent as a Durable Object; deploy once and Cloudflare runs the agents across its global network.source ↗ | A self-deployed library — you install and run it inside your own app or runtime; it is not a managed service.source ↗ |
| Memory & state | A core strength — each agent is a Durable Object with SQLite-backed local storage, persistent memory, durable identity, and recoverable execution, with no external database required.source ↗ | Provides message/state and streaming primitives; built-in long-term memory and conversation persistence are left to your own store.Unverified |
| MCP support | Nativesource ↗ | Nativesource ↗ |
| Integrations | Decorator methods, state sync, scheduling, WebSockets, AI chat persistence, workflow orchestration, email/voice, browser agents, sandboxed code execution, and React hooks (useAgent, useAgentChat).source ↗ | Tool calling, MCP servers and tools, structured object generation, and multimodal (text, speech, transcription, image, video) generation.source ↗ |
| Model providers | Workers AI by default, plus OpenAI, Anthropic, Google Gemini, or any other provider.source ↗ | Multi-provider by design — Anthropic, OpenAI, Google, xAI/Grok, Mistral, Meta, Perplexity, DeepSeek, and more (16+ providers, 100+ models).source ↗ |
