Safely Ship Microservice Features Faster

Junction is a drop-in replacement for your standard HTTP library which unlocks dynamic traffic routing. Accelerate delivery, test safely in production and isolate incidents. No service mesh required.

Don't let your APIs slow you down

Junction's self-service dynamic traffic routing empowers every developer to focus on shipping features, as opposed to debugging CI pipelines and production incidents

Accelerate Feature Delivery

Ship features faster with progressive deployments, dynamic traffic shaping, and built-in A/B testing—without waiting on infrastructure changes.

Junction enables canary deployments and blue/green releases, so you can deploy safely and expand gradually based on real-time observability.

Safely Test in Production

Confidently test new services, API changes, or experimental features in production without impacting customers.

Junction provides traffic mirroring, and isolated production sandboxes, so developers can validate changes with production data — before full rollout.

Avoid and Isolate Incidents

Reduce failed deployments and minimize downtime with adaptive resilience controls.

Junction dynamically routes traffic, balances loads, and applies circuit breaking to prevent cascading failures — ensuring reliable service performance, even under unexpected conditions.

How it works

Junction labs' architecture.

Dynamic Routing, No Proxy

Junction's dynamic routing is implemented as a native library, eliminating the need for sidecars or load balancers.

No-Migration, Drop in Library

Junction's HTTP library shims are drop-in replacements for the HTTP client you already use.

Managed Control Plane

We handle fleet updates and configuration distribution so you can focus on your business, not on running infrastructure.

Junction vs. Service Mesh

Service meshes offer similar features, but are costly, complex and hard to use.
