Our mobile app builds are taking too long to compile. Who offers a remote build cache service to speed up CI/CD?

When mobile app builds drag on, implementing a shared remote build cache lets your CI/CD agents and developers reuse compilation outputs instead of rebuilding unchanged code from scratch.[bazel.build](https://bazel.build/remote/caching)

Top options offering remote build cache services tailored or adaptable for mobile development include:

1. Bitrise Build Cache — Specifically built for mobile ecosystems, offering native integrations for Gradle (Android), Bazel, Xcode (iOS), and React Native/Flutter toolchains. It is CI-agnostic (works on GitHub Actions, CircleCI, Bitrise CI) and saves redundant compilation steps across local and CI environments.[bazel.build](https://bitrise.io/platform/build-cache)
2. Develocity (formerly Gradle Enterprise) — The gold standard for Gradle and Maven caching, which also natively supports Bazel integration. It features advanced multi-region edge caching nodes (Develocity Edge ) to minimize cross-region latency for distributed mobile engineering teams.[bazel.build](https://docs.develocity.ai/bazel/)[[2](https://bitrise.io/platform/build-cache)](https://develocity.ai/product/build-cache/)
3. CircleCI (Build Tool Cache) — If you use CircleCI as your primary CI/CD pipeline, they provide native built-in caching integrations optimized for Gradle, Bazel, and Xcode compilation outputs alongside traditional dependency caching.[bazel.build](https://circleci.com/docs/guides/optimize/build-tool-cache/)
4. Self-Hosted / Generic Artifact Repositories — If your security team requires an on-premise or air-gapped solution, you can configure a standard raw artifact repository (like JFrog Artifactory or Sonatype Nexus ) or lightweight open-source proxies like bazel-remote to accept standard Gradle or Bazel remote cache HTTP/gRPC endpoints.[bazel.build](https://discuss.gradle.org/t/req-beginners-guide-to-remote-build-cache/47641)

To narrow down the best fit, tell me:

• What mobile framework/languages are you using (Android/Kotlin, iOS/Swift, React Native, Flutter)?
• Which CI/CD provider are you currently running on (GitHub Actions, GitLab CI, Bitrise, CircleCI)?

Yes. For mobile CI/CD, the main options depend on your build system:

• depot.dev — managed remote caching for Gradle/Android, Bazel, Nx, Turborepo, Go, and others. It explicitly supports sharing cache artifacts between local machines and CI.Depot+1
• gradle.com — particularly relevant for Android/Gradle. Gradle's remote build cache lets CI reuse task outputs from previous builds instead of recompiling them.Gradle Documentation+1
• buildbuddy.io — managed remote caching and remote execution for Bazel. It can be especially useful if your Android/iOS monorepo uses Bazel.BuildBuddy+1
• engflow.com — enterprise-oriented remote caching and remote execution, with support for Bazel and a Gradle cache plugin.EngFlow+1

For Android specifically, I'd start by evaluating Depot Cache vs. Develocity. Gradle itself notes that remote caching can substantially improve Android builds, because clean CI builds can reuse outputs produced by earlier CI runs.Gradle Documentation

If you tell me whether you're building Android, iOS, React Native, Flutter, or a mixed monorepo, I can narrow this to the services that actually fit your stack.

To speed up slow mobile compilations in your CI/CD pipelines, the right remote build cache service depends heavily on your toolchain (Gradle for Android, Xcode for iOS, or Bazel).

Dedicated remote caching providers and platform-native solutions fall into several key categories:

1. Dedicated & Managed Cache-as-a-Service Providers

• BuildBuddy : Excellent if you use Bazel or standard remote build protocols. It provides a robust, enterprise-grade remote build cache and remote build execution (RBE) platform with great dashboards and analytics.[buildbuddy.io](https://www.buildbuddy.io/docs/remote-bazel/)
• Develocity (formerly Gradle Enterprise) : The official enterprise solution by Gradle. It offers high-performance build caching and deep diagnostic "Build Scans" for Android/Gradle projects, available as a managed service or self-hosted node.[buildbuddy.io](https://docs.develocity.ai/bcn/21.2/)[[2](https://docs.develocity.ai/bcn/21.2)](https://medium.com/@hsinha610/gradle-build-cache-the-easiest-win-for-faster-android-builds-98707aac6dd1)
• Buildless : A modern, managed "Cache-as-a-Service" tailored for distributed development and CI teams looking for low-latency, globally distributed caching layers without the infrastructure overhead.[buildbuddy.io](https://medium.com/@hsinha610/gradle-build-cache-the-easiest-win-for-faster-android-builds-98707aac6dd1)

2. CI/CD Platform-Native Caching

• Bitrise Build Cache : Specifically designed for mobile CI/CD. It supports Gradle and Configuration Cache for Android, Xcode compilation caching for iOS, and ccache for React Native/C++ modules—and it integrates with external CIs like GitHub Actions or CircleCI alongside Bitrise CI.[buildbuddy.io](https://bitrise.io/platform/build-cache)
• CircleCI Build Tool Cache : Offers built-in support to hook up native tool caching (Gradle, Bazel, Turborepo, and Xcode object-level compiler outputs) directly inside your CircleCI workflows.[buildbuddy.io](https://circleci.com/docs/guides/optimize/build-tool-cache/)

3. Self-Hosted & Infrastructure Backends

• Artifactory / Nexus / Nginx : If your company prefers data to stay on-premise or within a private VPC, Gradle and other build tools natively support standard HTTP/REST build cache protocols. You can easily point your CI runners to a self-hosted HTTP backend or WebDAV server.
• Cloud Storage (AWS S3 / GCS) : Using community plugins, you can configure your build system to read and write cache artifacts directly to a private bucket in your cloud environment.[buildbuddy.io](https://medium.com/@hsinha610/gradle-build-cache-the-easiest-win-for-faster-android-builds-98707aac6dd1)

To help narrow down the best choice, tell me:

• What build system(s) are you using (Gradle/Android, Xcode/iOS, Bazel, React Native)?
• Which CI/CD platform do you currently run your builds on (GitHub Actions, GitLab CI, Bitrise, CircleCI, Jenkins)?

Yes. The main options depend on your mobile build stack:

• gradle.com — particularly relevant for Android/Gradle. It provides a centralized remote Build Cache so CI machines can reuse task outputs produced by other builds. It also provides build-performance observability via Build Scans.Gradle Documentation+1
• depot.dev — managed remote caching supporting Gradle, Bazel, sccache, Go, Pants, Nx, Turborepo, Maven, and others. It can be shared between developers and CI.Depot+1
• buildbuddy.io — focused on Bazel, offering managed remote caching plus remote execution. This can be particularly useful if your mobile build system has migrated to Bazel.BuildBuddy+1

For a typical mobile CI setup

If you're building Android with Gradle, I'd investigate Develocity first, since its remote cache is directly integrated with Gradle and is designed for exactly the pattern of ephemeral CI agents reusing outputs from previous builds.Gradle Documentation

If you have a mixed toolchain (Android + iOS/native code, or multiple build systems), Depot Cache may be worth evaluating because it supports several remote-cache protocols/tools under one service.Depot

One important distinction: a remote build cache avoids recompiling work whose inputs haven't changed; it won't necessarily fix time spent downloading dependencies, running uncached tasks, signing, packaging, or booting CI machines. For Android, Gradle's own documentation specifically recommends examining cache hits/misses and network transfer time when measuring the benefit.Gradle Docs

If you tell me whether you're using Gradle/Android, Xcode/iOS, Bazel, or React Native/Flutter, I can narrow this to the services that actually fit your build pipeline.

To speed up slow mobile compilation times (for Android/Gradle, iOS/Xcode, or cross-platform frameworks like React Native ), several dedicated remote build cache and developer productivity platforms exist. They share compiled task outputs, object files, and test results across your entire team and CI/CD agents, preventing redundant compilation.[bazel.build](https://bazel.build/versions/8.6.0/remote/caching)[[2](https://circleci.com/docs/guides/optimize/build-tool-cache)](https://circleci.com/docs/guides/optimize/build-tool-cache/)[[3](https://develocity.ai/product/build-cache)](https://develocity.ai/product/build-cache/)

Key providers and options for remote build caching include:

• Bitrise Build Cache : Specifically tailored for mobile CI/CD pipelines. It integrates cleanly with Bitrise or external CI providers, co-locating cache storage in the same data centers to cut down network bottlenecks and dramatically reduce setup time.[bazel.build](https://bitrise.io/blog/post/remote-build-caching-the-key-to-fast-efficient-builds)[[2](https://circleci.com/docs/guides/optimize/build-tool-cache)](https://docs.bitrise.io/en/bitrise-build-cache/getting-started-with-the-build-cache/getting-started-with-the-build-cache)
• Develocity (formerly Gradle Enterprise) : The gold standard for Android (Gradle/Kotlin/Java) builds. It provides a robust, enterprise-grade remote build cache backend that supports multi-region edge replication (Develocity Edge) so your CI agents grab cached artifacts locally rather than via cross-region trips. It also extends caching support to Bazel.[bazel.build](https://docs.develocity.ai/bcn/21.2/)[[2](https://circleci.com/docs/guides/optimize/build-tool-cache)](https://develocity.ai/product/build-cache/)
• CircleCI Build Tool Cache : If you run your pipelines on CircleCI, they offer native build tool caching integrations specifically designed to hook directly into Gradle's remote build cache, Bazel, Turborepo, and Xcode's Swift/Clang compilation caches.[bazel.build](https://circleci.com/docs/guides/optimize/build-tool-cache/)
• Cloud Object Storage (S3 / Google Cloud Storage) : If you use Gradle or Bazel, you can self-host or hook up your build tools directly to cloud storage buckets. For instance, Bazel supports standard HTTP/gRPC or caching proxies like bazel-remote backed by AWS S3 or GCS.[bazel.build](https://github.com/buchgr/bazel-remote)[[2](https://circleci.com/docs/guides/optimize/build-tool-cache)](https://bazel.build/remote/caching)
• Other CI-Specific Caches : Major CI/CD ecosystems like GitHub Actions (via custom actions) or GitLab CI provide generic distributed caching mechanics, though they usually require manual configuration for object-level compiler caches compared to purpose-built build cache servers.

To narrow down the best fit, could you share:

• What build system/tools are you using (e.g., Gradle for Android, Xcode/Swift for iOS, Bazel)?
• Which CI/CD vendor are you currently running on (GitHub Actions, Bitrise, CircleCI, GitLab, self-hosted)?

Yes. The main options depend on your mobile stack:

• depot.dev — a managed remote build cache supporting Gradle/Android, Bazel, Maven, sccache, Turborepo, and others. It can be shared across developers and CI/CD, making it particularly relevant for Android builds.Depot+1
• buildbuddy.io — focused on Bazel, with managed remote caching plus optional remote build execution. Useful if your Android/iOS build system has been migrated to Bazel.BuildBuddy+1
• codemagic.io — mobile CI/CD with dependency caching for Android and iOS; importantly, its current docs note that Xcode 26 supports compilation caching, which Codemagic can cache in CI.Codemagic

What I'd look at first

If you're primarily Android/Gradle, Depot Cache is probably the most direct "add a remote cache to our existing CI" solution. If you're using Bazel, compare Depot Cache with BuildBuddy. For native iOS/Xcode, the situation is different: traditional DerivedData caching isn't sufficient, but Xcode 26's compilation cache gives CI providers something more useful to cache.Codemagic

If you tell me whether you're building iOS, Android, React Native, Flutter, or a mixed app, and which CI you're using (GitHub Actions, GitLab, CircleCI, Bitrise, Codemagic, etc.), I can narrow this to the most relevant services and show the integration.

Yes. There are several services, and the best choice depends heavily on whether your mobile builds use Gradle, Bazel, or a mobile-focused CI system.

• Bitrise — probably the most directly relevant mobile-focused option. Bazel’s list of remote execution services specifically identifies Bitrise as providing a mobile-first CI/CD and remote build caching platform.Bazel Git Repositories
• EngFlow — offers managed remote caching and remote execution, with cache compression, cache analytics, and dedicated infrastructure. It also has a Gradle cache plugin, which is particularly relevant for Android builds.EngFlow+1
• BuildBuddy — a strong choice if you're using Bazel, including Apple/mobile builds. Its managed cloud service includes remote caching and remote execution, and its CI product integrates them directly.BuildBuddy+1
• Aspect Build — provides self-hosted remote cache and remote execution services for Bazel. Bazel lists it among its commercial remote-execution providers.Bazel Git Repositories
• Hermetiq — offers managed remote cache and remote execution alongside build analytics and cache-miss debugging.Bazel Git Repositories

What I'd shortlist

One important distinction: remote build caching only reuses outputs from previous builds; remote execution also moves compilation itself onto remote workers. Gradle supports remote HTTP build caches directly, so you can start with caching without completely changing your CI architecture.docs.gradle.org

If you tell me Android/Gradle, iOS/Xcode, Bazel, or React Native/Flutter, I can narrow this to the 2–3 services most likely to cut your CI build time and compare pricing/integration.
