“Agno has emerged as one of the fastest-growing AI agent frameworks in 2026 — 39,100+ stars and a 424-contributor community.”
— DecisionCrafters review, DecisionCrafters · Apr 2026 - +
“Purpose-built for production with stateless scaling, session management, and enterprise features — closer to a 'framework + runtime + control plane' than just an SDK.”
— WorkOS engineering blog, WorkOS Blog · Mar 2026 - +
“Memory is stored in your database — you own the data, not the vendor. That alone made it the right call for our compliance posture.”

“Hermes wins on learning depth and security posture. For a solo developer or small team that uses the agent daily for 6+ months, Hermes compounds over time in ways other agents cannot.”
— Hands-on reviewer, heyuan110 blog · Apr 2026 - ·
“Agents with 20+ self-created skills complete similar future tasks 40% faster — but this improvement is domain-specific. Skills don't transfer across domains.”

How to Choose a Agent Frameworks Tool
Key criteria to evaluate when comparing Agent Frameworks solutions:
About Agno
Agno (formerly Phidata) is an open-source Python framework for building production-grade AI agents and multi-agent systems. With 39,100+ GitHub stars and an active 424-contributor community, it's emerged as one of the fastest-growing agent frameworks in 2026.
Agno provides three integrated layers: a Python SDK for building individual agents and multi-agent teams, a stateless FastAPI runtime called AgentOS for production deployment, and a control plane UI for monitoring, session management, and team operations. It supports 23+ LLM providers (OpenAI, Anthropic Claude, Google Gemini, and more) and ships 100+ pre-built tool integrations including web search, data analysis, file operations, and Model Context Protocol (MCP) servers.
Memory and knowledge systems are first-class: user memories, session memories, and RAG knowledge bases are stored in your database — you own the data, not Agno. Recent v2.5.13 (March 2026) added ReliabilityEval for agent evaluation, enhanced AgentOS APIs for session management, and Slack interface improvements. Agno is positioned as the production-first alternative to LangChain/LangGraph for Python teams.
About Hermes Agent
Hermes Agent is Nous Research's open-source autonomous AI agent with persistent memory — released February 2026 and the fastest-growing agent framework of 2026, hitting 95.6K GitHub stars in seven weeks. Unlike most agents that forget everything between sessions, Hermes maintains a curated memory of preferences, projects, environment, and lessons learned.
The memory system is layered: MEMORY.md and USER.md files live in ~/.hermes/memories/ and inject into the system prompt as a frozen snapshot at session start. On top of this, Hermes ships 8 external memory provider plugins — Honcho, OpenViking, Mem0, Hindsight, Holographic, RetainDB, ByteRover, and Supermemory — adding knowledge graphs, semantic search, automatic fact extraction, and cross-session user modeling.
Hermes also auto-generates skills: as the agent solves novel tasks, it captures the procedure as a reusable skill. Nous Research benchmarks show agents with 20+ self-created skills complete similar future tasks 40% faster (in tokens and time, not necessarily quality). The improvement is domain-specific — skills don't transfer across domains. Hermes is fully open-source and self-hostable, positioned as the agent that compounds in value the longer you use it.
