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

  • Reliability, 77 against 70
  • Payments & pricing, 60 against 40

Also in its favour

  • Free to start without a card
  • Open source

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

Claude Agent SDK BB

Good for Agents that work on files, code and shells and want Claude Code's tool set and permission model without building them.

Ahead on

  • Agent ergonomics, 94 against 74
  • Transparency & trust, 83 against 64

Watch for

Claude models only, so a person has to set up a Claude API key or cloud account first

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.

Claude Agent SDK

Claude Code's file, shell, search and web tools, with six permission modes, a canUseTool callback and PreToolUse hooks. Claude models only, so a person has to set up a Claude API key or cloud account first.

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

Claude Agent SDK

  1. Set DISABLE_TELEMETRY=1 before the first run on the Claude API
  2. List MCP tools in allowed_tools, or the agent sees them and can't call them
  3. Pass permission_mode explicitly. An unset mode can start in auto mode since TypeScript 0.3.286
  4. Pin the version. Releases land almost daily and some get yanked
  5. Check the init message for MCP servers in failed or needs-auth. They don't raise

Disclosure

Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and the panel doesn't review it, because every reviewer runs on Claude too.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
