Apinizer

Overview

Apinizer is an API and AI Gateway platform for routing traffic among APIs, large language models (LLMs), MCP, and agent-to-agent systems. Its gateway supports HTTP, gRPC, SOAP, WebSocket, and GraphQL, so it can handle several kinds of API traffic in one platform. Founded in 2015, Apinizer is headquartered in Bilkent, Ankara, Türkiye.

The product is aimed at organizations that run their own runtime, particularly banks, government bodies, and defense organizations. Its Community plan is free to self-host without a time limit, but it is limited to three API proxies and excludes the AI Gateway. Enterprise has unlimited API proxies and is priced by custom annual subscription.

Apinizer also has a developer portal with interactive API documentation, an API catalog, custom domains, and both options for developer authentication. Portal deployment is self-hosted, and the listed usage analytics are basic. For readers comparing portal tools, see our API Developer Portal Software list.

Key features

API and AI traffic management

The core gateway supports HTTP, gRPC, SOAP, WebSocket, and GraphQL. Enterprise adds the AI Gateway, which can route across multiple LLMs, track token use, set cost ceilings, cache semantically similar requests, and guard prompts. These AI controls are not part of Community.

Identity and security

Identity options include OAuth 2.0, OIDC, JWT, mTLS, LDAP or Active Directory, and SAML 2.0. Apinizer says secrets tagged with @SecretData are encrypted before they are stored in the database and decrypted when required by the runtime.

The security page describes an audit aspect for Manager repository saves. It records the actor, timestamp, changes before and after the save, and an optional reason. Apinizer lists ISO 27001, PCI-DSS, BDDK, KVKK/GDPR, HIPAA when configured, and NIST 800-53 among the standards its controls were designed to satisfy; its SOC 2 controls audit is in progress.

Integrations and deployment

Enterprise includes API Integration with more than 15 enterprise connectors. Deployment options include container images for Docker, Podman, containerd, Kubernetes, OpenShift, and Nomad, as well as standalone Linux installers. Listed standalone targets are RHEL 8/9 and Ubuntu 20.04/22.04 on x86_64. The pricing page also lists Kubernetes, VM, and Docker installation targets.

Pricing

The pricing model is freemium. A free plan is available, there is no free trial, and Enterprise pricing is available on request. Enterprise technical support is offered 8×5 or 24×7 with response-time SLAs and a named Customer Success Manager.

Platforms

Apinizer is listed for Linux, Windows, web, and self-hosted use. Its deployment options include standalone Linux installers and container images for a range of container runtimes and orchestration platforms. The developer portal is self-hosted.

Who it's for

Apinizer is most clearly suited to organizations that operate their own runtime and need a gateway for conventional API traffic alongside AI workloads. Its stated audience—banks, government, and defense organizations—points to teams that may value its identity options, audit records, and controls designed around listed compliance standards. Smaller deployments can use Community, but its three-proxy limit and lack of AI Gateway place clear boundaries on that option.

Pros and cons

• Pros: Community is free to self-host without a time limit; the gateway supports five protocol types; identity features span several common standards and systems; deployment options include standalone Linux and multiple container platforms.
• Cons: Community is capped at three API proxies and lacks the AI Gateway; Enterprise pricing is not listed; the portal is self-hosted and its usage analytics are basic.

Alternatives

For other API gateway options, compare Gravitee API Gateway, Kong Gateway, Tyk API Management, and Zuplo. For adjacent access management and developer portal tools, see F5 BIG-IP APM, Workato Developer API Portal, Apigee API hub, and ReadMe.

Verdict

Apinizer combines a multi-protocol gateway, identity and audit features, and self-managed deployment choices, with an AI Gateway reserved for Enterprise. Its free Community plan offers a way to use the core platform without a time limit, but the three-proxy ceiling makes it a limited option for larger API estates. Teams considering Enterprise should account for custom annual pricing and request a quote to assess fit.
