Pricing
FreemiumThe LangChain and LangGraph frameworks are MIT-licensed, open source, and completely free to use with no usage limits from LangChain itself. The commercial layer, LangSmith, offers three tiers: Developer is free and includes 1 seat, 5,000 base traces/month, 14-day data retention, the prompt playground, and basic evaluations. Plus costs $39 per seat per month and includes 10,000 base traces included, full evaluations, custom dashboards, and email support; overage traces beyond the included allowance cost $2.50 per 1,000 (base, 14-day retention) or $5.00 per 1,000 (extended, 400-day retention), with base traces upgradeable to extended for an additional $2.50 per 1,000. Enterprise pricing is custom and adds dedicated support, custom retention policies, SSO, self-hosting, and higher trace volumes; exact figures require contacting LangChain sales. LangGraph Cloud/Platform deployment is billed separately from LangSmith, with plans starting around $35/month for hosted agent compute. Total production cost typically also includes underlying LLM API usage and vector database infrastructure, which are billed independently by those providers.
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.

LangChain Pros & Cons

Pros

  • Core LangChain and LangGraph frameworks are fully open source (MIT license) and free with no usage caps
  • Massive, mature open-source ecosystem with 350M+ monthly downloads and extensive third-party integrations
  • LangGraph Studio gives developers a genuinely useful visual IDE for debugging complex multi-agent state machines
  • LangSmith's free Developer tier is a real, usable starting point, not just a truncated trial
  • Deep integration between framework, orchestration, and observability layers reduces tool-stitching for teams that commit to the ecosystem

Cons

  • Real production costs go beyond the advertised $39/seat LangSmith price once trace overages, vector DB, and infrastructure are factored in
  • Per-seat LangSmith pricing scales linearly with team size, unlike usage-only competitors like Langfuse
  • Free Developer tier caps out at 5,000 traces/month and 14-day retention, tight for active production debugging
  • Committing deeply to the LangChain/LangGraph ecosystem can create lock-in, even though the core framework itself is open source
CrewAI

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
