In their own words
Apiman
Apiman is open-source API management software for securing API access and handling discovery and governance across the API lifecycle. Its policy-based runtime governance supports multiple plans with different service levels for the same API. The management layer includes a REST API, Manager UI, and standalone Developer Portal, along with multi-tenancy, events, notifications, permissions, and approvals. Teams can create custom policies and components with Java plugins, which can be loaded at runtime without restarting. Gateways scale independently from the Manager and can keep running if the Manager goes down. Supported gateway platforms are Vert.x, WildFly, and Tomcat. Standard policies cover authorization, BASIC authentication, IP allowlisting and blocklisting, OAuth2/JWT through the Keycloak plugin, and HTTP security headers. Apiman is licensed under Apache License 2.0, with no features behind paywalls. It is primarily an HTTP gateway: WebSockets lack explicit testing or support, while raw TCP, raw UDP, and messaging protocols are unsupported. Version 3.x is community-supported; versions 2.x and 1.x are unsupported. Commercial support packages are also described as including 24/7 support and CVE patching and alerts.
Fusio
Fusio is an open-source API management platform for connecting business logic and infrastructure to APIs. It is self-hosted and brings databases, microservices, and custom scripts behind a unified gateway that handles routing, authentication, and request validation. TypeSchema models add validation and generate OpenAPI specifications and client SDKs in multiple languages. A developer portal provides documentation, testing tools, and API keys; API monetization features can manage plans, quotas, subscriptions, and billing. AI-assisted development and AI/MCP integration are described as optional. Official adapters cover services and technologies such as AWS, Google Cloud, GraphQL, LDAP, MongoDB, Redis, SQL, Stripe, and SOAP. Worker runtimes are available for PHP, JavaScript, and Python, with SDKs listed for C#, Go, Java, JavaScript, PHP, and Python. Fusio also documents lifecycle management, access policies, and API analytics. Install options include a release archive, Composer, or Docker. The code is licensed under Apache 2.0. Fusio is available for free.
