Apollo
The API Orchestration Platform for AI Agents, Web, and Mobile Apps
Apollo is an API orchestration platform that connects AI agents, web, and mobile applications to GraphQL and REST APIs. It provides a unified graph layer, GraphOS, where backend teams define data once and deliver it to any interface, addressing technical debt from one-off backends and inconsistent data access across applications.
GraphOS includes Apollo Connectors for bringing REST APIs into a declarative GraphQL platform, GraphQL federation, response caching, federated subscriptions, and the GraphOS Router. It offers a schema registry, schema checks, Schema Proposals for collaboration workflows, and GraphQL-native metrics exportable to DataDog or OpenTelemetry. An Apollo MCP Server supports building AI agents and MCP tools from GraphQL and existing REST data sources.
Apollo is packaged in four editions: a free plan for students and hobbyists with limited developers and rate-limited routing, a Developer plan for small production teams, and Standard and Enterprise plans for larger organizations with custom pricing. Paid plans are usage-based on API request volume with automatic volume discounts, and include seat-based developer limits, SSO, audit logging, and tiered support levels.
