Pricing
FreeThe AI SDK itself is completely free and open source (MIT license), with no cost, tiers, or usage limits imposed by the library. Costs only arise if developers use Vercel's optional AI Gateway to access models: every Vercel team account gets $5 of free Gateway credits each month, refreshing every 30 days, usable indefinitely for experimentation across free-tier-eligible models (a subset of the full catalog). Beyond the free tier, or for full catalog access, Gateway usage is billed pay-as-you-go with zero markup on tokens, meaning developers pay exactly the underlying provider's list price, whether using Vercel-provided credits or bringing their own API keys (BYOK). Optional features carry small separate fees: team-wide Zero Data Retention (ZDR) and provider allowlists each cost $0.10 per 1,000 successful requests. Credit purchases may incur payment processing fees, though Enterprise invoicing avoids these. Developers can also skip the Gateway entirely and connect directly to any provider's API using their own keys, in which case only that provider's standard rates apply, independent of Vercel.
FreemiumCrewAI offers a free Basic plan that includes the visual editor and AI copilot, GitHub integration, and 50 workflow executions per month, ideal for individuals prototyping agent workflows. The Enterprise plan uses custom pricing sized to workflow volume and requires contacting sales for a quote; it adds enterprise connectors, SSO (Microsoft Entra, Okta), role-based access control, dedicated VPC or on-premises deployment, FedRAMP High and SAM certified infrastructure options, flexible overage on executions, dedicated support, and a 45-day guided onboarding program. The underlying open-source CrewAI framework itself remains free and MIT licensed for self-hosted use via GitHub.

Summary
The open-source TypeScript toolkit for building AI apps and agents
Build, govern, and scale collaborative multi-agent AI crews for enterprise workflows
Vercel AI SDK Pros & Cons
Pros
- Genuinely free and open source with no paywalled core features or artificial usage caps
- Switching model providers typically takes one line of code, avoiding vendor lock-in
- Works in any JavaScript/TypeScript environment, not just on Vercel's own hosting
- Massive, active community with 18.5M+ weekly downloads and 696+ contributors backing rapid iteration
- Optional AI Gateway offers genuinely zero-markup token pricing, unlike many competing LLM proxy services
Cons
- TypeScript/JavaScript-only, so teams working in Python, Go, or other languages need a separate solution (a Python SDK is currently in beta)
- Deepest convenience (built-in Gateway, zero-config model routing) assumes a Vercel-adjacent workflow, even though the SDK itself works anywhere
- Rapid version releases (SDK 5 and 6 shipped within roughly a year) mean upgrade paths and breaking changes require active maintenance
- Team-wide Zero Data Retention and provider allowlists carry a small per-request fee ($0.10 per 1,000 requests), on top of pass-through token costs
CrewAI Pros & Cons
Pros
- Free tier and fully open-source MIT-licensed framework lower the barrier to getting started
- Built independently from scratch with no LangChain dependency, giving a lightweight, distinct architecture
- Strong enterprise governance layer with SSO, RBAC, audit trails, and human-in-the-loop controls
- Flexible deployment options across CrewAI cloud, dedicated VPC, or customer-owned infrastructure
- Wide enterprise adoption reported at roughly 65% of the Fortune 500 with strong case study results
- Active open-source community with tens of thousands of GitHub stars and rapid iteration
Cons
- No public per-seat enterprise pricing, requiring a sales conversation to get a quote
- Free tier is capped at 50 workflow executions per month, which limits testing at any real scale
- Full governance features like SSO and RBAC are locked behind the Enterprise plan
- Building sophisticated multi-agent crews still requires Python and coding knowledge for full customization
- Enterprise onboarding process runs 45 days, which is a longer ramp than simpler no-code automation tools
