# TraceMachina/nativelink

NativeLink is a Nix-powered, open source, high-performance build cache and remote execution server, compatible with Bazel, Soong, Pants, Buck2, Reclient, and other RE-compatible build systems. It offers drastically faster builds, reduced test flakiness, and support for specialized hardware.

## What it is
NativeLink is a high-performance remote build cache and remote execution server written in Rust, speaking the open Remote Execution API. It accelerates builds for Bazel, Buck2, Pants, Soong, Reclient, Goma, and other RE-compatible build systems by caching artifacts and distributing work across machines.

## Use cases
- speed up bazel builds with a remote cache
- self-host a remote execution server for buck2
- share build artifacts across CI and developer machines
- reduce CI compute costs with content-addressable caching
- distribute C++ compilation across a build farm
- wire an AI coding agent to remote build caching via MCP

## When to choose
- your team uses Bazel, Buck2, Pants, Soong, or other Remote Execution API build systems and builds are slow
- you want a single self-hostable Rust binary for both cache and remote execution
- you need cross-compilation or specialized hardware workers
- you want to reduce CI costs via cache hits across teams and agents

## When to avoid
- your project uses plain make or npm scripts without Remote Execution API support
- you need a fully managed build service with GUI dashboards and autoscaling out of the box (enterprise tier)
- you only need local caching for a single developer

## Facets
- artifact type: service
