CI/CD Testing Guide: What to Test at Every Pipeline Stage

Shipping fast is great until the wrong thing ships fast. A CI/CD pipeline can move code from commit to production in minutes, but speed alone does not tell you whether a login still works, a checkout flow still completes, or a critical form still submits. That is the job of CI/CD testing. The best pipelines do more than pass builds. They catch small problems before they become customer-facing ones, using the right mix of unit, integration, API, browser, smoke, and post-deployment tests.

Announcing Codemagic Patch: an open-source CodePush rebuild for React Native

Having maintained a CodePush fork for 18 months and served billions of updates, we decided it was time for an overhaul. We’re big fans of CodePush, and it was a great benefit to the React Native community. But, it was written in 2015 and had some weaknesses. The biggest of these was architectural, with limitations in how update checks and release metadata could scale. The result, Codemagic Patch, is now public and available to self-host.

React Native New Architecture and OTA Updates: What Teams Need to Know in 2026

The React Native New Architecture is no longer optional. From React Native 0.82 onwards it is mandatory, the legacy architecture is gone, and every team still running it is now carrying technical debt that will need to be resolved. For most teams, the migration conversation quickly turns to tooling. Does our CI/CD pipeline still work? Does our crash reporter still integrate correctly? Do our analytics tools need updating?

Maven Central rate limits: What you need to know

Maven Central introduced rate limits for high volume users. Bitrise is protecting its users from rate limiting errors on dependency resolution by hosting a repository manager, a sort of pull-through cache, to reduce load on Maven Central and provide faster dependency downloads. This is enabled by default at not additional cost for all Bitrise hosted builds.

Controlled Rollouts in React Native: How to Push OTA Updates Without Breaking Production

The ability to push an update directly to your users’ devices without App Store review, without delay, without any action required from the user, is one of the most powerful capabilities available to a React Native team. Over-the-air (OTA) updates change how fast you can respond to bugs, iterate on features, and ship improvements. But that power cuts both ways. A bad OTA update reaching 100% of your users at once is considerably worse than a bad store release.

Best 7 Software Engineering Platforms for 2026

Software engineering teams are operating in environments that look very different from just a few years ago. Modern development workflows now span Kubernetes clusters, cloud infrastructure, CI/CD pipelines, AI-assisted coding, distributed architectures, internal developer portals, observability platforms, and dozens of engineering tools that all need to work together without slowing delivery velocity.

Build Cache for React Native setup guide

Learn how to leverage Bitrise Build Cache to reuse build outputs and compilation data in your React Native projects. This guide from Lex Zavala walks you through the essential steps for configuring Build Cache for React Native: adding the required workflow steps, configuring command-line prefixes for better data segmentation, and using the Bitrise dashboard to track cache hit rates and invocation durations for every build.

Stop building your modular mobile app the slow way

Your CI pipeline worked fine when the app was young. Then the app grew. Features got split into modules. Teams formed around those modules. And somewhere along the way, what used to be a 4-minute build became a 25-minute one. Then 35. Now nobody pushes to main before lunch because the queue is already backed up. If this sounds familiar, you are not alone. According to Google’s 2024 Developer Survey, 83% of Android apps over 500,000 lines of code struggle with build performance.
