HeyReach CLI is a high-performance, open-source command-line tool and programmatic automation interface designed specifically for the HeyReach LinkedIn outreach platform. Maintained under the SpaceCorps engineering collective, the project provides developers, growth engineers, and autonomous AI agents with a single, standalone native binary capable of operating seamlessly across macOS, Linux, and Windows without runtime dependencies or interpreter overhead.
The original prototype CLI was created as a .NET global tool (`Heyreach.Console`) by Niels Bosma. In 2026, under the SpaceCorps CLI porting blueprint, the entire tool was re-architected as a native Rust 2024 binary (`heyreach`). This transition eliminates runtime startup overhead, achieving cold-start latencies of 1 to 3 milliseconds, and introduces secure OS keystore storage, deterministic multi-account scoping, and complete agent self-documentation via heyreach agent-readme.
HeyReach CLI adheres to the core SpaceCorps standards:
--json, and standardized exit codes.--account <name> to prevent accidental cross-tenant execution.HeyReach CLI is licensed under the permissive MIT License. Full source code, test suites, and documentation are hosted publicly at github.com/SpaceCorps/Heyreach-Cli.
