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 Nous Research's open-source AI agent platform built around a radical idea: agents should get better the more you use them. Unlike static assistants that start fresh every session, Hermes creates a closed-loop learning system — it builds skills from experience, refines them during use, persists knowledge across conversations, and searches its own history to apply what it's already learned. The v0.8.0 release (April 8, 2026) ships with 40+ built-in tools, a skills system for procedural memory, persistent user profiles, and scheduled automation via cron. Interfaces include a terminal UI plus native connectors for Telegram, Discord, Slack, WhatsApp, and Signal. It runs across six execution backends — local, Docker, SSH, Daytona, Singularity, and Modal — meaning it scales from a $5 VPS to a full GPU cluster without rewriting your setup. The agent supports OpenRouter, OpenAI, Anthropic, and other LLM providers interchangeably. Builders migrating from OpenClaw (the predecessor project) get a smooth upgrade path. With 6,400+ GitHub stars on trending today, Hermes represents what the community has been asking for: a production-grade, self-hosted agent that compounds its usefulness over time rather than resetting to zero.
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 skills-from-experience loop is the feature I've wanted from every agent platform. Add in multi-backend support from local to Modal and you have something genuinely deployable in real infrastructure, not just a weekend demo.”
“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.”
“A self-improving agent sounds exciting until you realize 'skills from experience' can also mean confidently learning bad habits. The lack of a skill audit or rollback mechanism means you could spend weeks debugging subtle behavioral drift without knowing where it started.”
“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.”
“This is the architecture the 'AI coworker' narrative has been promising. When an agent remembers how YOU work and refines its approach across months of use, we stop talking about AI tools and start talking about AI colleagues. Hermes is early proof that this is buildable today.”
“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 multi-channel interface (Telegram, Slack, WhatsApp, Discord) means I can have the same persistent agent follow me across every platform I actually use. The cron-based automation means it can handle recurring content tasks without me re-explaining context each time.”
