n8n is a workflow automation platform that lets you connect apps, APIs, databases, AI models, and other services into automated workflows. You build workflows visually by connecting nodes that trigger actions, move data, apply conditions, run code, or interact with external services.

n8n has expanded beyond traditional automation with built-in AI agent capabilities. You can create agents that use models, tools, memory, workflows, and business data to handle multi-step tasks, while still controlling what those agents are allowed to do. It supports multi-agent systems, RAG workflows, MCP, and human approval steps.

The platform offers more than 500 integrations and supports custom API connections when a service does not have a ready-made integration. n8n can be used through its hosted cloud service or self-hosted on your own infrastructure, and developers can add JavaScript or Python when a workflow needs more control than the visual builder provides.

 Connect applications and services into visual workflows with triggers, actions, conditions, data processing, and custom logic.

 Build agents that can use AI models, tools, memory, workflows, and connected business systems to complete multi-step tasks.

 Connect popular applications and services through pre-built nodes, with custom API requests available for other services.

 Add JavaScript or Python to workflows and deploy n8n through its cloud service or on your own infrastructure.

Claude AI Agents are Anthropic’s tools for building AI systems that can plan and carry out multi-step work instead of only responding to individual prompts. Developers can build agents with Claude that reason through a task, use tools, interact with applications, and work toward completing a larger objective.

 Platform for building these agents into applications and workflows. Developers can combine Claude models with tools, prompts, and other capabilities, while Claude Code provides an agentic coding experience where developers can delegate work such as code migrations and bug fixes directly from the terminal.

For longer-running and asynchronous work, Claude Managed Agents provides a managed environment where agents can read files, run commands, browse the web, and execute code without developers having to build the entire agent runtime themselves. Agents can be configured with models, system prompts, tools, MCP servers, and skills.

Gumloop is an AI agent platform for automating work across the apps and websites a company already uses. Instead of building a separate automation for every small task, teams can create AI agents that understand a job, use connected tools, browse websites, work with data, and complete the task.

Its agents can work with more than 300 connectors and can also use a real browser to click, type, upload files, download information, and interact with websites even when there is no API available. Agents can sign in through saved credentials, hand the browser back to a person when approval or login is needed, and then continue the task afterward.

Gumloop is built for teams as well as individual workflows. Agents can be triggered by apps, scheduled to run repeatedly, or used directly through Slack, Microsoft Teams, and Gmail. The platform also lets agents review their own runs, evaluate their performance, and improve how they handle recurring work.
