Xcode compilation caching with Depot Cache

Depot Cache now supports Xcode compilation caching. Reuse outputs across CI builds to reduce build times, with no extra setup on Depot runners.

The evolution of the Depot Metal autoscaler

Depot Metal's autoscaler grew from a simple pressure loop into a topology-aware system for compute and storage. Next, it must predict demand and converge on desired capacity.

Introducing the Fibonacci Benchmark™ for CI runners

Taking the Sandbox TTI benchmarks one step further for fun.

Staying in control of your codebase in the AI era

AI can produce code faster than you can review it, but you're still the one on call when it breaks. You need an AI-assisted workflow you trust: linter guardrails, reference tests the agent can copy, tight AGENTS.md files, and PRs small enough to review. The goal isn't to avoid AI, it's to stay in control of what it ships.

Now available: Nested virtualization support on Depot CI sandboxes

We're excited to announce that Depot CI sandboxes now support nested virtualization which enables efficient Android Emulator usage.

How we got microVMs booting in under a second

Depot CI's VM scheduler is just-in-time: no pre-warming, no warm pool of standby VMs. We stacked optimizations to get microVM cold boots from 7 to 9 seconds down to under a second, and this post walks through each one.

The differences between QEMU microvm and Cloud Hypervisor

microVMs are everywhere in 2026, especially for CI and sandboxes. But when you're building a platform, choosing between QEMU microvm and cloud-hypervisor isn't obvious. We compare API support, GPU passthrough, snapshotting, live migration, and hotplugging.

What we learned optimizing EC2 macOS build performance

We ran iOS builds across different EBS disk configurations on EC2 macOS instances to find the optimal setup. We discovered that simply throwing more IOPS at the problem doesn't work the way you'd expect.

Scaling Depot: Solving a thundering herd problem

When upstream systems fail, retries pile up fast and your database becomes the bottleneck. Here's how we used PlanetScale's Insights to identify and fix the queries that were slowing us down during thundering herd events.

Now available: GitHub Actions log search

We're launching GitHub Actions log search in Depot. Search across all your historical CI logs with powerful keyword search and filtering capabilities.
