If you are evaluating an Apigee alternative, you are not alone. Since Google absorbed Apigee into its cloud platform, a growing number of organizations have found themselves facing rising costs, deepening vendor lock-in, and an increasingly opaque product roadmap.

The open-source API gateway landscape in 2026 includes Kong, Envoy, APISIX, Tyk, Gravitee, and STOA. This guide compares their architectures, MCP support, multi-tenancy, and licensing — with a focus on AI-readiness and European sovereignty.
The open source API gateway landscape in 2026 looks very different from what it was just two years ago. The rise of AI agents, the Model Context Protocol (MCP), and stricter European regulations have reshaped what organizations expect from their API infrastructure. This article provides an honest comparison of the leading open-source gateways and where each one excels.
Migrating from Software AG webMethods API Gateway™ to an open-source alternative is achievable in 4-6 months using a phased, zero-downtime approach. This guide covers what makes webMethods migrations distinct — the Integration Server (IS) dependency, the Designer-based policy model, the IBM licensing entanglement — and provides a concrete roadmap for platform teams ready to act.
