## Which one, for what

### AgentOS (BB)

Good for: TypeScript teams that want long-term memory, personas, voice and channel adapters and multi-agent teams in one package, and that will pin versions.

Ahead on:
- Schema & documentation, 92 against 74
- Security & auth, 81 against 65
- Payments & pricing, 60 against 40

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: Version 0.12.12, with 27 releases on 7 and 8 October 2026 and breaking minors 0.11.0 and 0.12.0 on the same day

### CrewAI (B)

Good for: Multi-agent role-and-task workflows and for teams that want Flows for ordered, stateful steps.

Ahead on:
- Agent ergonomics, 80 against 74
- Transparency & trust, 72 against 64

Also in its favour:
- No key needed to call it

Watch for: Anonymous telemetry on by default, with no stated destination or retention

## Verdicts

**AgentOS.** A TypeScript agent framework with typed tools, six multi-agent strategies, checkpointed graphs, approval gates and no telemetry of its own. It is at 0.12.12 after 98 releases in 90 days, two of them breaking on 7 October 2026. No MCP client was found in the package, and code tools an agent writes run in an in-process node:vm context.

**CrewAI.** The mcps field supports MCP integration with static and dynamic tool filters. Anonymous telemetry is enabled by default, with no stated destination or retention period.

## Before you call either

### AgentOS

1. Pin an exact version of @framers/agentos. Feature commits ship as patch releases while it is 0.x, and breaking changes ship as minors
2. Leave emergentConfig.allowSandboxTools off unless forged code runs through an executor that isolates. The default executor shares the host process
3. Pass your own ICheckpointStore to compile() for runs that must survive a restart. The default store is in memory
4. Set hitl.approvals.beforeTool for tools that write, and choose a handler. No approval gate is on by default
5. Use Node 22 or newer, and set a provider key such as OPENAI_API_KEY or ANTHROPIC_API_KEY. The provider is detected from the environment

### CrewAI

1. Set CREWAI_DISABLE_TELEMETRY=true before the first run
2. Put MCP keys in headers, not in the URL as the docs' Exa example does
3. Pin a stable version. Development builds share the crewai name on PyPI
4. Add a PRE_TOOL_CALL hook for any tool that writes or sends
5. Check the logs for MCP connection warnings. A failed server doesn't stop the agent
