20 open-source repos that turn GPT-6 Astra into an all-day agent
A GitHub list organized into memory, tools, execution and observability layers, from LangGraph and Mem0 to E2B and Langfuse, plus a full agent architecture chain for Astra.
GPT-6 Astra makes AI agents f…cking illegal 20 GitHub repos for turning a powerful model into a system that can remember, use tools, keep working the whole day 01 LangGraph ▸ https://github.com/langchain-ai/langgraph 02 PydanticAI ▸ https://github.com/pydantic/pydantic-ai BUILD THE BRAIN 03 CrewAI ▸ https://github.com/crewAIInc/crewAI 04 AutoGen ▸ https://github.com/microsoft/autogen 05 smolagents ▸ https://github.com/huggingface/smolagents → agents that reason through code GIVE IT MEMORY 06 Mem0 ▸ https://github.com/mem0ai/mem0 07 Graphiti ▸ https://github.com/getzep/graphiti → temporal knowledge graphs 08 Cognee ▸ https://github.com/topoteretes/cognee → data → knowledge graph → memory 09 Letta ▸ https://github.com/letta-ai/letta → stateful agents across sessions GIVE IT HANDS 10 Composio ▸ https://github.com/ComposioHQ/composio → 1,000+ agent toolkits 11 MCP Servers ▸ https://github.com/modelcontextprotocol/servers 12 Browser Use ▸ https://github.com/browser-use/browser-use 13 Playwright MCP ▸ https://github.com/microsoft/playwright-mcp LET IT EXECUTE 14 E2B ▸ https://github.com/e2b-dev/E2B → isolated agent sandboxes 15 OpenHands ▸ https://github.com/All-Hands-AI/OpenHands 16 Daytona ▸ https://github.com/daytonaio/daytona → infrastructure for running AI-generated code MAKE IT SURVIVE 17 AgentOps ▸ https://github.com/AgentOps-AI/agentops → tracing + debugging + costs 18 Langfuse ▸ https://github.com/langfuse/langfuse → traces + evals + observability 19 BrowserGym ▸ https://github.com/ServiceNow/BrowserGym 20 DeepEval ▸ https://github.com/confident-ai/deepeval → test the agent before trusting it the architecture: GPT-6 Astra → context → memory → plan → tools → sandbox → execute → observe → evaluate → recover → continue 4 stacks I’d actually build: coding: Astra → LangGraph → Composio → E2B → OpenHands research: Astra → Graphiti → Browser Use → Playwright MCP persistent agent: Astra → Letta → Mem0 → Cognee → Composio production: Astra → PydanticAI → Daytona → Langfuse → DeepEval the model can keep getting smarter but intelligence isn’t the whole system the real leverage is everything you build around it ⭣
