APIs are the lifeblood of modern software systems, and when your applications are mission-critical, your API management must be reliable, secure, and scalable. But managing them can often feel like navigating a maze: scattered endpoints, inconsistent access control, versioning chaos, and limited visibility.

digiRunner is an open-source, UI-driven, developer-first API management platform that simplifies end-to-end governance—from development to deployment—for mission-critical environments. Whether you're managing a few APIs or orchestrating a full-scale microservices architecture, digiRunner delivers the clarity, speed, and control your business demands.

From Challenges to Solutions: How digiRunner Transforms

Mission-Critical API Management

Scenario	Without digiRunner	With digiRunner
Managing API Security	Manual token handling, inconsistent policies	Unified RBAC, OAuth2, and API key management via UI
Monitoring API Traffic	Logs scattered across systems	Real-time visual dashboards and alerts
Routing Requests	Static routes, manual edits	Smart, dynamic routing based on payload or headers
Microservices API Consolidation	Each service exposed separately	Unified API Gateway abstracts all services
API Version Management	Manual tracking and potential conflicts	Built-in version control with routing strategies
Development Onboarding	Steep learning curve, sparse docs	AI-powered documentation and step-by-step tutorials

Key Features

• Smart Routing Engine – Route API traffic based on URL paths, headers, query parameters, and other request metadata. Supports dynamic and conditional routing logic for microservices, legacy systems, and multi-version APIs.

• Role-Based Access Control (RBAC) – Set granular access policies per user, team, or role. Combine this with API key authentication or OAuth2/OIDC to ensure only the right consumers can access your APIs.

• Rate Limiting & Quotas – Define limits on request rates per consumer, application, or endpoint. Enforce burst limits, sustained usage thresholds, and usage quotas to maintain reliability under high load.

• Token-based Auth – Seamlessly integrate secure authentication flows using OAuth2, OpenID Connect (OIDC), and static API keys. Supports multi-tenant identity providers for enterprise use cases.

• Real-Time Monitoring – Gain full visibility into request metrics, error rates, latency, and traffic volume through live dashboards. Identify anomalies and performance bottlenecks before they affect end users.

• Easy Setup – Deploy digiRunner anywhere—locally for development, in Docker containers for portability, or on cloud platforms for production-scale infrastructure. Configuration is UI-driven with CLI support.
