Pros
  • Genuinely open-source (Apache 2.0) with active Google engineering behind it, not a hosted-only product
  • Multi-language: first-class Python, Java, and Go SDKs — rare among agent frameworks that are usually Python-only
  • Built-in dev UI (`adk web`) with trace inspection, event stream, and session replay speeds up debugging enormously
  • Model-agnostic via LiteLLM — Gemini is default but Claude, GPT, and local models plug in cleanly
  • Rich multi-agent primitives out of the box: SequentialAgent, ParallelAgent, LoopAgent, and hierarchical sub-agents
  • Tight Google Cloud integration for deployment (Cloud Run, GKE, Agent Engine) plus native BigQuery/Vertex Search tools
  • Evaluation harness with trajectory-level scoring is included, not a separate paid add-on
  • First-class MCP (Model Context Protocol) client and server support
  • Real-time call suggestions and transcription inside Chrome
  • Works across Zoom, Google Meet, Teams plus Ringover/Aircall
  • Includes a practice mode with AI-generated buyer objections
  • Credit-based pricing is accessible to individual reps
Cons
  • Documentation and examples lean heavily on Gemini + Google Cloud; non-Google paths work but feel like second-class citizens
  • API surface is still evolving — breaking changes between minor versions have been common through 2025-2026
  • Multi-agent orchestration primitives are powerful but the graph/callback model has a real learning curve compared to a plain prompt loop
  • Agent Engine deployment is convenient but locks you into GCP billing and quotas
  • TypeScript/Kotlin support lags the Python SDK in features and community examples
  • No public API for integration or workflow automation
  • Credit model can get expensive for heavy daily users
  • Less mature than enterprise tools like Gong or Chorus
  • Closed source with limited transparency on data handling
