Claude
- +Strong writing, reasoning, and coding plus interactive Artifacts in one assistant
- +Open MCP Connectors wire it into Gmail, Workspace, Slack, Jira, and Zapier
- +Generous free tier across web, desktop, and mobile; Research and Cowork add real agentic work
- -Most of the product is assistant/copilot grade; the agentic modes are newer and narrower
- -Cowork ships as a research preview and (for now) on the desktop app
Google Agent Development Kit (ADK)
- +Backed by Google with first-class deployment to Vertex AI and Cloud Run
- +Built around the open A2A protocol for cross-framework agent interoperability
- +Model-agnostic via LiteLLM despite Gemini-first defaults
- -A framework, not a product: you build, host, and secure agents yourself
- -Strongest when paired with Google Cloud, which can imply lock-in
