Which one is for you

Pick CrewAI if

  • Fits if you want to try multi-agent workflows in a visual editor
  • Works for a company that wants a VPC or self-run deployment

Look elsewhere if

  • Tight if you build for real: 2 automations and 50 executions a month
  • Not for you if you want a self-serve paid plan, as none is published
  • Watch out: SSO, role-based access and enterprise connectors are Enterprise only
  • Skip it if you want instant sign-up for Enterprise, which starts with a trial request and a 45-day onboarding

Pick Letta if

  • Fits if you are a developer who wants agents that keep their memory between runs
  • Works for people who already pay for a coding plan and can bring that key

Look elsewhere if

  • Tight if you stay free, because there is no included model usage and 3 agents is the cap
  • Pricey if you code heavily, as the pricing page says $100 to $200 a month or more of usage
  • Watch out: server tool time is billed at $0.00015 a second against your credits
  • Watch out: more than one person needs Teams Pro, since Pro covers a single user

Key features

CrewAI

Visual editor and AI copilot
A no-code canvas builder, guided by an AI copilot, that can be exported to Python code.
Role-based agents and workflows
Agents are given roles, and deterministic workflows control how they hand work to each other.
Tracing and evaluation
Tracing of every LLM call, tool call and memory read with cost accounting, plus OpenTelemetry and LLM testing.
Governance controls
Human-in-the-loop approval gates, guardrails, and on Enterprise, SSO, role-based access and PII redaction hooks.
Flexible deployment
Run on CrewAI cloud; Enterprise adds a dedicated VPC or the customer's own infrastructure. Agents can be exported as an MCP server.

Letta

Persistent agent memory
Agents are stateful: they carry memory across sessions, and memory repositories are versioned in git so changes can be tracked.
Letta Code CLI
An open-source harness installed with npm for coding agents, personal assistants and agents that work on local files, with skills and schedules.
Agent SDK and app server
Developers can embed stateful agents in their own applications, with a self-hosting option and a protocol for external tools.
Channels and cloud agents
Cloud-hosted agents connect to Slack and a GitHub integration; the channels guide also lists Telegram, Discord, WhatsApp and Signal.
Bring your own keys
All plans accept your own model API keys, and usage then goes through your provider account instead of using Letta credits.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
  • The differences and the answers to the questions are worked out from those listings.
