Zapier is an automation and AI orchestration platform for connecting business applications, data, AI models, and agents. Its workflows use triggers and actions to move information between tools and perform tasks such as formatting new Asana projects, connecting incoming email to OpenAI for a customer-service workflow, scheduling recurring scrapes, and sending notifications when qualifying data appears. The Zapier site says it supports workflows and agents across more than 9,000 app integrations, with governed access, model management, and guardrails. It also provides Zapier MCP for connecting AI clients such as Claude, ChatGPT, Cursor, and OpenClaw to configured tools, plus a beta Zapier SDK and SDK CLI for building integrations.

AstrBot is an open-source all-in-one AI agent chatbot platform and development framework that connects instant-messaging platforms with LLM services, plugins, multimodal features, MCP, skills, knowledge bases, persona settings, and automatic context compression. It supports platforms including QQ, Telegram, WeCom, Feishu, DingTalk, Slack, Discord, LINE, and others, and can connect to services such as OpenAI-compatible APIs, Anthropic, Gemini, Ollama, LM Studio, Dify, Coze, and Alibaba Cloud Bailian. Its plugin system offers one-click installation of more than 1,000 plugins, while its agent sandbox isolates code and shell execution and supports session-level resource reuse. AstrBot provides a WebUI and web ChatUI with agent sandbox and web-search support, and can be deployed with uv, Docker or Docker Compose, desktop applications, or other documented deployment methods.

LangBot is an open-source platform for building and operating AI-powered instant-messaging bots. It connects large language models to platforms including Discord, Telegram, Slack, LINE, QQ, WeChat, WeCom, Lark, DingTalk, KOOK, and Matrix, supporting multi-turn conversations, tool calling, multimodal input, streaming output, and agent workflows. The platform includes a built-in retrieval-augmented generation knowledge base, integrations with systems such as Dify, Coze, n8n, Langflow, and Deerflow, and an event-driven plugin system with MCP support. A browser-based management panel configures, manages, and monitors bots, while its multi-pipeline architecture supports separate bot workflows and operational monitoring. LangBot can be run through LangBot Cloud, a one-line uvx launch, Docker Compose, or other deployment methods. It also exposes an MCP endpoint that mirrors its HTTP API for programmatic management of bots, pipelines, plugins, and models.

Pizza Bot is a local-first inbox for long-running AI-agent work, developed at Amazon. It lets users start or schedule tasks, switch conversations, and return to completed work in an Unread queue or approval requests in an Action queue. Its stateful DeepAgents/LangGraph runtime checkpoints runs so they can continue after a client disconnects; cron and webhook triggers can also start work. Electron, browser, and terminal clients communicate with an api-server over HTTP/SSE, while skills provide tool-scoped subagents and MCP servers extend the system. The project supports model providers including Amazon Bedrock, Anthropic, Google Gemini, OpenAI, OpenRouter, and Ollama. It stores application state locally, requires explicit folder permissions for local file access, and is distributed under the Apache 2.0 license with desktop installers for macOS, Windows, and Linux.

DocsAlot is a documentation platform for publishing AI-readable help centers and developer documentation. The service provides hosted MCP and llms.txt support and tools to keep documentation current.
