About AstrBot is an open-source, cross-platform Agentic AI assistant and chatbot platform built for chats, automation, and smart collaboration. It runs directly in messaging apps and provides an agent runtime with Sub-Agents, complex workflows, tool calls, context management, scheduled tasks, runtime controls, and isolated agent sandboxes for real actions. Native MCP and Skills support expands AI capabilities, while a plugin-driven architecture provides access to more than 1,000 community extensions for productivity, group operations, content workflows, and external integrations. AstrBot supports OpenAI, Google, Anthropic, and OpenAI-compatible providers with flexible model switching, as well as text generation, vision, speech-to-text, text-to-speech, and embeddings. Its built-in knowledge base supports PDF, DOCX, and Markdown parsing, hybrid dense and BM25 retrieval, and references to multiple knowledge bases in a single conversation.	About Flue is an open agent framework for building durable AI agents with a programmable TypeScript harness. Created by the team behind Astro, it uses a React-like hooks API to compose agent behavior, persistent state, lifecycle events, models, tools, sandboxes, subagents, skills, and MCP servers in code. Agents are stateful and addressable over HTTP, keep context across conversations and events, and can change capabilities as work progresses. Flue records every session in a durable stream, so accepted work survives crashes, restarts, and deploys; interrupted sessions resume automatically and clients reconnect without starting over. Developers can run agents locally, in CI, from their own backend, or orchestrate them with systems such as Cloudflare Workflows and Inngest. Secure sandboxes let agents run commands, edit files, and do real work, while tools connect them to APIs and data. Flue is powered by Pi and supports different LLM providers, allowing teams to choose the models they want.
