NativeLink

NativeLink is a self-hosted Rust platform for sharing build artifacts and running compilation or tests on distributed workers. It suits engineering organizations with demanding, repeatable builds across multiple developers, CI jobs, or AI coding agents. Its open-source entry tier is unusually capable, but teams must be comfortable operating Linux or macOS servers and reviewing licensing boundaries for production use.

Overview

NativeLink combines a content-addressed build cache with remote execution and observability. The cache deduplicates artifacts, allowing developers, CI pipelines, and agents to reuse results instead of rebuilding identical outputs. Remote execution sends compilation and tests to worker fleets on AWS, GCP, or bare metal, including GPU, ARM, and Apple Silicon machines.

Deployment is flexible but not managed: one Rust binary can be configured as the cache, scheduler, or worker. NativeLink is built by Trace Machina, which serves sectors including semiconductors, robotics, autonomous vehicles, AI research, life sciences, and financial services.

Key features

Cache and execution coverage

NativeLink supports Bazel, Buck2, Siso, Soong, Pants, Goma, BuildStream, and CMake through recc. Language and compiler coverage includes C++, Rust, Python, Go, Java, Kotlin, and Swift. That breadth makes it a credible shared backend for polyglot repositories, while teams using an unlisted build system should not assume compatibility.

Remote workers can include GPUs, ARM processors, and Apple Silicon, so heterogeneous hardware is a practical advantage for specialized builds. The trade-off is infrastructure ownership: customers provision and maintain the server and worker fleet.

Integrations and controls

CI integrations cover GitHub Actions, GitLab, Buildkite, and Jenkins. Cloud and storage connections include AWS, GCP, Azure, S3, GCS, and Redis. The product also lists Claude Code, Copilot Workspace, Devin, Cursor, and Windsurf, making shared build results relevant to AI-assisted development workflows.

Security controls include SSO/SAML, mutual TLS, signed inputs, hermetic builds, and queryable audit trails. NativeLink states that SOC 2 and ISO 27001 are complete and that it complies with GDPR and CCPA/CPRA. These controls are useful for regulated teams, though self-hosting still makes architecture and operations your responsibility.

Pricing

Open Source

The Open Source plan costs free. It is self-hosted, includes community Slack support, distributed scheduling, remote caching, all listed build systems, and major cloud providers. This is the sensible starting point for individuals, open-source projects, and teams able to run their own service.

The important limitation is licensing rather than a usage quota. Most of the monorepo is FSL-1.1-Apache-2.0, while metrics and remote persistent workers are Business Source License modules. Shared production use of those modules requires Enterprise or a separate license, so a nominally free deployment may not cover every production requirement.

Enterprise tiers

Enterprise Tier 1 costs $180,000 a year, billed billed monthly. It targets private companies under $100M valuation and includes self-hosting on Kubernetes, six support hours per month, and a 24-hour response SLA. It fits organizations that need contractual support and Kubernetes deployment without the higher service commitment.

Enterprise Tier 2 costs $360,000 a year, billed billed monthly. It is for public companies or private companies valued at $100M or more, with 12 support hours monthly and a four-hour response SLA, alongside Kubernetes self-hosting. The price is difficult to justify for smaller teams, but the faster response target is aimed at production-critical build infrastructure.

Platforms

Clients run on Linux, macOS, or Windows. Servers support Linux and macOS, so Windows-only server environments are not a fit. NativeLink is self-hosted and available as a configurable Rust binary rather than a hosted endpoint.

Who it's for

Choose NativeLink when shared caching and distributed execution can materially shorten large builds, especially with Bazel-family systems, mixed CPU architectures, GPUs, or Apple Silicon. It is also a strong candidate for organizations that need audit trails, enterprise identity controls, and integration with established CI.

Look elsewhere if you want a fully managed cache, a Windows server, or a simple single-developer compiler cache. Operating workers, storage, upgrades, and licensing compliance requires platform expertise that smaller projects may not have.

Pros and cons

• Pros: Combines remote caching and execution in one deployable binary, supports broad build-system and language coverage, handles GPU/ARM/Apple Silicon workers, and offers substantial security and CI integrations.
• Pros: The free self-hosted tier includes distributed scheduling, remote caching, all listed build systems, and major cloud providers.
• Cons: Server support excludes Windows, and customers must operate the infrastructure themselves.
• Cons: Metrics and remote persistent workers have Business Source License restrictions for shared production use.
• Cons: Enterprise pricing starts at $180,000 a year, with support hours capped by tier.

Alternatives

• Bitrise is the better choice for mobile teams wanting a freemium service with hosted Android and iOS workflows and a free Hobby tier.
• Ccache suits developers who only need a free, single-file compilation cache under GNU GPL rather than remote execution.
• EngFlow Remote Caching is worth considering for a hosted-style free tier limited to one machine and 32 CPU cores, with enterprise expansion.
• cachepot is a straightforward Apache-2.0 open-source cache with no hosted plans stated.
• FosterStack offers a self-hosted MIT-licensed cache and a paid team tier for multi-user controls.
• MozJPEG is for JPEG encoding, not general remote build caching or execution.
• bazel-remote is preferable when you need a configurable-size Apache-2.0 cache focused on Bazel-compatible workloads.
• BuildFetch Cache provides a free hosted/open-source cache allowance with stated storage, traffic, request, and retention caps.

Verdict

NativeLink is a strong choice for build-heavy organizations that can self-host and want one platform for shared artifacts, remote workers, and enterprise controls across varied hardware. Its main reason to choose it is the combination of broad build-system support and distributed execution in a free entry tier. Look elsewhere if managed hosting, Windows servers, or a lightweight local cache matters more than fleet-scale capability and control.
