8 Best Postman Alternatives & Competitors (2026)

Hasura provides instant GraphQL and REST APIs over Postgres and other data sources with strong authorization and event triggers. It excels at rapid backend creation for CRUD workloads but offers less emphasis on multi-protocol orchestration or AI agent connectivity compared to Apollo's MCP server and declarative REST connectors. Teams often choose Hasura for simpler Postgres-centric projects while Apollo better suits complex federated environments with existing REST services.

AWS AppSync delivers managed GraphQL APIs with real-time subscriptions and offline support tightly integrated into the AWS ecosystem. It simplifies backend scaling for mobile and web but offers narrower REST orchestration and fewer collaborative schema tools than Apollo GraphOS. Organizations already invested in AWS may prefer AppSync, whereas Apollo provides more flexible multi-cloud and AI agent capabilities.

Kong is a popular API gateway focused on traffic management, plugins, and microservices routing across REST, gRPC, and GraphQL. It provides robust security and observability but requires more manual configuration for GraphQL schema federation and lacks Apollo's native connectors or AI-specific tooling. Kong fits high-volume gateway needs while Apollo targets unified data orchestration for apps and agents.

Apigee from Google Cloud focuses on API management, monetization, and developer portals with strong analytics. It handles REST and GraphQL proxies well yet lacks Apollo's declarative connectors and built-in GraphQL development studio. Apigee suits enterprises needing API productization while Apollo emphasizes internal orchestration and agentic AI workflows.

MuleSoft offers Anypoint Platform for API-led connectivity and integration across legacy and modern systems. Its visual tooling accelerates REST and SOAP orchestration but provides less native GraphQL federation depth than Apollo. Large enterprises use MuleSoft for broad integration while Apollo targets GraphQL-centric developer efficiency and AI experiences.

Tyk is an open-source API gateway with GraphQL support, rate limiting, and dashboard features. It enables quick deployment of secure APIs but requires additional setup for schema management and AI agent access that Apollo includes natively. Tyk appeals to cost-conscious teams needing gateway basics whereas Apollo delivers a more complete orchestration platform.

Prisma offers a type-safe ORM and query builder that generates GraphQL-ready APIs from database schemas. It speeds up application development with excellent TypeScript support but focuses more on database access than broad REST-to-GraphQL orchestration or AI tooling found in Apollo. Prisma suits greenfield apps while Apollo handles enterprise-scale API unification.
