Show HN: Ez – a macOS command runner that flags when a command gets slower

Ez is a macOS command-line tool that runs shell commands while tracking their execution time, alerting the user when a command takes noticeably longer than it has in the past. The project was posted to Hacker News on August 20, 2026 by user frankbyte in a Show HN thread, linking to the GitHub repository.

The core premise is straightforward: Ez wraps an existing command, records how long it takes to complete, and flags runs that exceed a learned baseline. The goal is to surface performance regressions in development workflows — build times, test suites, or any repeated shell task — without requiring the user to manually time and compare runs.

The tool is scoped to macOS and is available via its GitHub repository. No pricing, licensing details, or installation method are described in the available source material beyond what the repository itself contains.

No company, team size, funding, or founding date is mentioned in the source. The project appears to be an individual open-source effort by the author frankbyte, based solely on the Show HN post. No comments had been posted to the HN thread at the time of publication, and the post had received 3 points.

The developer workflow tooling space includes a range of timing and profiling utilities — time, hyperfine, and various CI-integrated benchmarking tools among them — but Ez's stated differentiator is passive, persistent baselining rather than explicit benchmarking runs. The repository is the primary record of the project's current scope and roadmap; no additional coverage or corroborating sources were available at time of writing.
