Every optimization runs automatically on every build
Most CI tools make you choose: speed or reliability. Build Acceleration runs all three optimizations simultaneously so the gains multiply, not just add.
Build Intelligence
Incremental compilation for Bazel, Gradle, and more — only changed code gets recompiled. Shared remote cache across your entire team.
Docker Layer Caching
1-click caching for dependencies and Docker layers — no cache key expressions or manual paths. Works across npm, Maven, pip, Gradle, and more.
Harness Cloud
Fully managed, isolated build machines for Mac, Linux, and Windows. No noisy neighbors, no infrastructure to maintain.
Build infrastructure that scales with you
Scale seamlessly. Cloud machines fine-tuned for building and testing code, ensuring your pipelines run smoothly regardless of complexity or volume.
SLSA 3. Every build runs on an isolated, tamper-proof machine with cryptographically signed provenance — SLSA Level 3 compliance out of the box.
Platform support. Run macOS, Linux, and Windows builds from the same pipeline definition. No separate farms, no OS-specific tooling to maintain.
Only build what changed
Shared remote cache. Cache is shared across the entire team — not just per-branch. If a colleague already compiled the same artifact, your build skips it entirely.
Zero configuration. Harness automatically detects your build system and configures the remote cache. No Bazel RC files, no Gradle settings — just enable and go.
Works alongside Docker Layer Caching. Build Intelligence handles compilation outputs. Docker Layer Caching handles dependencies. Together, they eliminate most of the wait.
Build system support
Incremental compilation works with the build systems your team already relies on.

Layer-by-layer caching
Ask AI. Fix it in seconds.
Instant cache configuration. Tell Harness AI your build system — it detects your package manager, configures caching, and wires up Docker layer caching automatically.
Build bottleneck analysis. Ask which modules rebuild most, which stages run longest, and where cache hit rate is low. AI surfaces the highest-impact fix first.
Right-sizing recommendations. AI reviews CPU and memory usage from Resource Insights and suggests the smallest machine that fits your workload, without slowing builds down.
Get started with Harness Continuous Integration
Build Intelligence, Docker Layer Caching, and Harness Cloud are available in all Harness CI plans. Takes minutes to configure and starts delivering results on the first build.
