## 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 87

Also in its favour:
- 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

### Agent Development Kit (ADK) (BB)

Good for: Teams on Google Cloud or working outside Python, and for anyone who wants approval, guardrail callbacks and evaluation in one framework.

Ahead on:
- Security & auth, 92 against 81

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

Watch for: Two critical CVEs in 2026, one of them in tool confirmation itself

## 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.

**Agent Development Kit (ADK).** Python, TypeScript, Go, Java and Kotlin. Two critical CVEs in 2026, one of them in tool confirmation itself.

## 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

### Agent Development Kit (ADK)

1. Upgrade to 2.5.0 or later before relying on tool confirmation
2. Always pass tool_filter to McpToolset
3. Pin a 2.x minor and read the changelog's breaking section before each bump
4. Install the bigquery-analytics extra if you use pyarrow, since 2.7.0
5. Keep ADK Web off public interfaces, or run 1.28.1 or later at the least
