Best Alternatives to AgentKit by Scalekit in 2025

The automation platform for everyone

Zapier is a mature automation platform connecting to over 6,000 apps, and it now offers AI agent capabilities through Zapier Central. It excels at no-code workflow automation and can serve as a backend for agents that need to trigger actions across SaaS tools. While it lacks native MCP support, its vast integration library and reliability make it a strong alternative for teams seeking broad connectivity without building custom auth flows.

Make provides a visual automation builder with deep integrations across thousands of apps, and its API allows AI agents to execute complex workflows. It offers granular control over data transformations and error handling, making it suitable for production agents that require robust orchestration. Unlike AgentKit, Make doesn't focus on user-scoped authentication out of the box, but it can be combined with OAuth management for similar outcomes.

Workflow automation for everyone

n8n is an open-source workflow automation tool with a fair-code license, offering self-hosting and extensive integration nodes. It supports AI agent nodes and can act as an MCP server via community plugins, giving developers full control over authentication and data flow. For teams that prioritize transparency, customization, and avoiding vendor lock-in, n8n is a powerful alternative to AgentKit's managed gateway.

Composio is an integration platform specifically designed for AI agents, providing toolkits that handle authentication and API calls across 200+ apps. It offers managed OAuth, scoped permissions, and a unified interface similar to AgentKit, but with a stronger focus on developer-friendly SDKs and agent frameworks. Composio's emphasis on tool quality and agent-native design makes it a direct competitor for production agent deployments.

Arcade AI provides a platform for building and deploying AI agents with secure tool access, including authentication management and a library of pre-built integrations. It emphasizes user-level permissions and auditability, akin to AgentKit's user-scoped actions. Arcade's developer-centric approach and support for custom tools make it a viable alternative for teams needing fine-grained control over agent capabilities.

Toolhouse offers a cloud-based platform for equipping AI agents with tools, including a marketplace of integrations and managed authentication. It simplifies tool calling with a unified API and supports popular agent frameworks. While its integration count is smaller than AgentKit's, Toolhouse's focus on ease of use and rapid prototyping makes it attractive for startups and teams testing agent workflows.

LangChain provides an open-source framework with a rich ecosystem of tool integrations (100+ built-in tools) and support for custom tools. While it doesn't offer a managed gateway with built-in user authentication, it gives developers complete flexibility to implement OAuth and scoping themselves. For teams already using LangChain for agent orchestration, its tooling can serve as a lightweight alternative to AgentKit, especially when combined with an auth provider like Auth0.
