Auth0 vs. Scalekit

Auth0 takes a modern approach to identity, providing secure access to any application, for any user. Safeguarding billions of login transactions each month, Auth0 delivers convenience, privacy, and security so customers can focus on innovation. Auth0 is part of Okta, The World’s Identity Company™. Auth0 lets you quickly integrate authentication and authorization for web, mobile, and legacy applications, with new Fine Grained Authorization (FGA) that goes beyond role-based access control. Authenticate users across all applications with a customized, secure, and standards-based single login.

Scalekit is the agent integrations and tool calling platform for AI agents. It works as an MCP gateway between an agent and the tools it calls, managing authentication, permissions, execution, and logging, so engineering teams don't build or maintain that layer themselves. The catalog covers 500+ pre-built connectors and 10,000+ tools across SaaS apps, APIs, and MCP servers, including Salesforce, Slack, Gmail, HubSpot, Zendesk, Gong, Notion, Snowflake, and Google Drive.
