LangChain
Pros
- + LangSmith run traces showed me the exact prompt, tool output and latency at every node of a failed agent run
- + LangGraph's explicit graph model (state, cycles, checkpointing, interrupts) gave me deterministic control I could not get from loop-style agents
- + Developer tier is free with 5,000 traces/month included; evaluation on a 40-example dataset was repeatable once configured
- + Integration layer covers the widest provider set of any framework I have worked with
- + Enterprise tier offers self-hosted and hybrid deployment, which matters for teams with data-residency constraints
Cons
- - I had to mechanically rewrite working code across major versions twice; the surface has moved under me
- - Billing stacks seat fees, trace volume and LSU metering — one agent query can generate several billable traces
- - LangGraph checkpointers, reducers and interrupt semantics take real onboarding time; the docs assume the mental model
- - No models, end-user UI or guardrails policy included — it is a substrate, not a product
- - Evaluation setup (datasets, experiments, feedback queues) is engineering work before it pays off
CrewAI
Pros
- + Role/goal/backstory abstraction produced clearly differentiated agent behaviour from one underlying model in my three-agent crew test
- + Export-as-MCP-server worked as documented — the crew came up as a tool server a coding agent could call
- + Tracing, OpenTelemetry export and Slack-based human-in-the-loop pauses made a recurring workflow operable
- + The open-source framework installs from PyPI and runs anywhere Python runs; no platform commitment required
- + Studio's AI copilot generated a working workflow skeleton from a plain-language description
Cons
- - Free tier is 50 workflow executions/month — a demo allowance, not a working quota
- - The $25/month Professional tier shown on archived pricing pages is gone; after free there is only a sales conversation
- - Token burn surprised me: a reviewer loop on a three-agent crew cost far more than a single-agent equivalent
- - Hierarchical delegation occasionally looped or duplicated work until I tightened task boundaries
- - SSO, RBAC and PII redaction are Enterprise-gated, so the free tier is unusable for sensitive data
