Callstack brings React and React Native delivery expertise to the platform layer. We strengthen the infrastructure behind build, test, release, and rollout without replacing the team that owns it. - **Shorten feedback loops.** Improve caching, parallelization, runners, and test execution so engineers see results sooner. - **Make releases observable.** Connect build, rollout, and post-release signals so teams can act before issues reach more users. - **Balance control and cost.** Use hosted, self-hosted, or hybrid infrastructure where each model makes operational and economic sense. - **Leave the platform team stronger.** Automation, documentation, and runbooks stay with the team that operates the system. Services ## Run delivery on infrastructure you control. ### Use Cases - [Release Automation](https://www.callstack.com/services/release-process-optimization): Automate build, signing, testing, and rollout steps so releases need less manual coordination. - [CI/CD Modernization](https://www.callstack.com/services/ci-cd-modernization): Replace brittle pipelines with faster, more observable workflows built for current delivery demands. - [Build & Test Acceleration](https://www.callstack.com/services/build-test-acceleration): Shorten feedback loops with better caching, parallelization, and runners tuned to your workloads. - [OTA Rollout Management](https://www.callstack.com/services/ota-rollout-management): Ship changes and bug fixes between App Store releases through over-the-air updates. - [Release Monitoring & Observability](https://www.callstack.com/services/monitoring-observability): Monitor releases and trigger alerts when rollout, build, or post-release signals show risk. - [Delivery Cost Optimization](https://www.callstack.com/services/delivery-cost-optimization): Reduce spend on hosted runners, device clouds, and release tooling by moving the right parts of the stack in-house.
