Google Agent Development Kit (ADK) is an open-source Python framework for building, evaluating, and deploying multi-agent systems at production scale. It handles orchestration with built-in tool calling, memory management, structured output, streaming, and first-class connectors for Vertex AI, Gemini, and any OpenAI-compatible API. ADK's philosophy is agent-as-code rather than visual builders. Agents are Python classes with typed inputs/outputs, making them testable, versionable, and CI/CD-compatible from day one. The framework includes an evaluation harness, artifact management, session persistence, and failure recovery — all the production plumbing that most agent frameworks leave to the developer. The multi-agent layer handles spawning, communication, and coordination between agents as a platform primitive rather than custom glue code. With 8,200+ GitHub stars since its April release, ADK is already one of the most-watched agent frameworks. The combination of Google's infrastructure backing, Apache 2.0 licensing, and pragmatic production focus sets it apart from research-oriented frameworks. It's the entry point to Google's broader agentic infrastructure stack, including the newly announced 8th-gen TPUs.

Hermes Agent is an open-source, self-improving AI agent from Nous Research that learns from every task it completes. Unlike stateless assistants, Hermes maintains persistent memory across sessions using full-text search and LLM-powered summarization, autonomously creating and refining skills as it works. The agent runs everywhere — from a $5 VPS to GPU clusters or serverless platforms like Daytona and Modal that hibernate when idle. It ships with 40+ built-in tools and integrates with MCP servers, while supporting any model via Nous Portal, OpenRouter, OpenAI, or Anthropic endpoints with instant switching. What makes Hermes distinctive is its multi-platform gateway: one agent accessible via CLI, Telegram, Discord, Slack, WhatsApp, Signal, or email — all sharing the same memory and skill base. With 23k GitHub stars and 9k new this week, it's one of the fastest-rising agentic frameworks in the ecosystem.
Reviewer scorecard
“The evaluation harness and session persistence are what make this real. Most frameworks give you the happy path and leave you to build all the production scaffolding yourself. ADK ships with the hard parts included, which is why it hit 8K stars so fast.”
“The skill persistence is the killer feature here — most agents lose everything between sessions, Hermes actually compounds. Running it on a $5 VPS with serverless fallback is a clever cost model, and the cross-platform gateway means your agent is wherever you are.”
“Google has a graveyard of developer platforms it's abandoned — Stadia, Firebase, Cloud Functions v1. Betting your production agent infrastructure on Google's continued commitment to an open-source framework is a real risk, especially when LangChain and CrewAI have two years of community momentum.”
“Self-improving AI that autonomously creates and refines its own skills sounds impressive until you read about the debugging nightmare when those skills go wrong. Nous Research hasn't published rigorous evals on skill quality, and 'grows with you' is marketing until there's reproducible benchmarking.”
“Google is making a stack bet: ADK → Vertex AI → 8th-gen TPUs. If that stack wins, ADK becomes the Rails of agentic AI — the default framework for the majority of production deployments. The infrastructure integration is the moat that makes this more than just another orchestration layer.”
“Hermes is an early glimpse of what personal AI infrastructure looks like — not a chat window, but a persistent agent that accumulates organizational memory. This model of AI-as-colleague rather than AI-as-tool is where the industry is heading.”
“Typed inputs and outputs for agents finally makes multi-agent pipelines debuggable. I can build a research → draft → review → publish pipeline and actually understand what's happening at each stage — instead of debugging opaque string-passing between prompts.”
“The idea that my agent learns my creative workflow over time and gets smarter about it is genuinely exciting. The multi-platform access means I can ping it from wherever inspiration strikes without context switching.”
