Side-by-side comparison of AI visibility scores, market position, and capabilities
Remote Docker build cache service turning 10-minute CI builds into 2-minute builds; shared persistent layer cache across CI runners competing with Docker Build Cloud for container build acceleration.
About
Depot is a remote Docker build cache and layer storage service that dramatically accelerates Docker image builds in CI/CD pipelines — providing a shared, persistent build cache that allows consecutive builds to reuse unchanged layers across different machines and parallel runners, turning 10-minute Docker builds into 2-minute builds. Founded in 2022 and headquartered in the United States, Depot targets engineering teams running Docker-based CI/CD on GitHub Actions, CircleCI, or other cloud CI platforms where each build starts from scratch without access to previous build cache.\n\nDepot's shared remote cache stores Docker build layers in cloud infrastructure and makes them available to all CI runners across a team — when a build starts, it checks Depot's cache for previously built layers and only rebuilds what has changed. This is particularly impactful for large monorepos and multi-stage Dockerfiles where base dependency layers (npm install, pip install, Maven dependencies) represent significant build time but rarely change between commits. Depot also provides native ARM build support (building ARM64 images without slow emulation).\n\nIn 2025, Depot competes with Docker's own Build Cloud, Buildkite Depot, and engineering teams' self-managed BuildKit caching solutions for CI Docker build optimization. The Docker build performance market has grown as teams running microservices in containers experience significant CI cost and time from slow Docker builds. Depot's managed service eliminates the infrastructure management burden of self-hosted build cache. The 2025 strategy focuses on expanding GitHub Actions integration (native action available in GitHub Marketplace), growing ARM native build adoption as teams adopt Apple Silicon development, and building build analytics that help teams identify slow Dockerfile patterns.
CNCF-graduated cloud-native proxy powering Istio and AWS App Mesh service meshes; 2025 AI Gateway v0.1 enabling AI API traffic management competing with NGINX in Kubernetes.
About
Envoy is the most widely deployed cloud-native proxy, originally developed at Lyft and now a Cloud Native Computing Foundation (CNCF) graduated project since November 2018 — serving as the default sidecar proxy in Istio, Open Service Mesh, AWS App Mesh, and other service meshes, as well as the foundational technology behind many commercial API gateways and edge proxy products. Envoy processes traffic for millions of microservices globally, handling load balancing, service discovery, observability, and traffic management at the infrastructure layer.\n\nEnvoy's architecture as a high-performance, extensible proxy has made it the de facto standard for cloud-native network infrastructure — its xDS API for dynamic configuration allows platforms like Istio to manage Envoy configurations at scale without restarting proxies, while its rich observability (distributed tracing, detailed metrics) makes it essential for understanding microservices traffic patterns. Envoy Gateway 1.1 (released August 2024) added support for the Kubernetes Gateway API v1.1, standardizing how Kubernetes workloads expose services externally.\n\nIn February 2025, Envoy reached another milestone: the first stable open-source AI Gateway (v0.1), developed by Bloomberg and Tetrate and backed by CNCF, was built on Envoy to provide unified access management, rate limiting, and observability for AI model APIs — positioning Envoy as infrastructure for AI application traffic alongside traditional microservices traffic. Envoy competes with NGINX and HAProxy for traditional proxy workloads but has largely displaced them in Kubernetes and cloud-native environments. The 2025 strategy focuses on the AI gateway use case, continued Kubernetes Gateway API adoption, and the commercial ecosystem of Envoy-based products (Tetrate, Solo.io, and others) that fund ongoing development.
