Your self-hosted GitHub runner is ghosting your public repo. It's not a bug, it's a hidden checkbox. Here's the 30-second fix

Public NATS JetStream is wide open by default. Here's how to lock it down with JWT plus NKEY auth: per-client identity, fresh nonces, real revocation.

Monk CI has completed its SOC 2 Type 1 audit and earned ISO 27001 certification, two of the most widely recognized standards for security in a CI/CD platform. For teams running Docker builds and pipelines on Monk CI, it means the security of your code is now backed by independent, third party assurance. This post explains what each certification covers, the difference between SOC 2 Type 1 and Type 2, and what these milestones mean for your team's security and procurement reviews.

Explained how ephemeral CI runners, cache compression tax, and shared compute silently drain engineering hours and how a persistent runner architecture fixes the issues.

Monk CI runners replace the GitHub Actions cache with a persistent BuildKit state volume. Build layers stay on the local disk between jobs, so builds skip the layer export/import round trip on every run. Repositories with large or frequently rebuilt layer graphs benefit most.

GitHub Actions workflows often become unmaintainable "fat" workflows as logic is incrementally embedded directly into YAML. This creates a divide between developers who "program" in YAML, resulting in 500–1000 line files full of complex conditionals, and those who "configure" it, keeping workflows around 50–60 lines by pushing logic into scripts.

Most developers assume instances.bulkInsert exists simply to reduce HTTP requests. That explanation is true, but it misses the real engineering story. The biggest difference between instances.insert and instances.bulkInsert isn't network efficiency. It's how Google Compute Engine thinks about infrastructure. One API creates an individual virtual machine. The other allocates an entire fleet. That distinction fundamentally changes how the control plane validates requests, reserves capacity, schedules workloads, and provisions virtual machines.

GitHub Actions is the default CI/CD tool for teams building on GitHub. It lives in your repo, runs on `push`, and gets you from zero to a green check fast. But default and best aren't the same thing. As pipelines grow, the same teams keep hitting the same walls: shared runners that crawl, jobs that queue during peak hours, Docker builds that eat minutes, and a monthly bill that climbs faster than headcount. If any of that sounds familiar, you're in the right place. Below are seven of the best GitHub Actions alternatives in 2026, compared on what actually matters in production (build speed, pricing model, concurrency, and hosting) so you can pick the right replacement instead of the most popular one.
