Zest

Zest is a native macOS application designed to simplify and speed up the workflows of software developers by enabling them to control AI coding agents and command-line tools through a unique interface. With a simple keyboard shortcut and a flick gesture, developers can trigger a customizable "wheel" of tasks—which are defined per project through YAML configuration—and hand them off to coding agents like Claude, Codex, Gemini CLI, or even any shell command. All operations run locally, keeping code and API keys private and eliminating the need for cloud-based servers.

The tool supports rapid context-based coding, testing, and deployment actions specific to many programming environments, including but not limited to Xcode, Node.js, and Python projects. Furthermore, teams can share custom wheels by committing their configurations, enabling consistent and automated workflows across projects. Integrations are flexible and extendable, accommodating developers who want to script or automate unique actions using their agent or terminal of choice.

Zest's pricing model is straightforward: a single lifetime license that grants access to all features and updates for the 1.x versions. There's a two-week free trial during which no account or payment information is required. Security-minded developers benefit from the app's design, as nothing is sent to third-party servers, and users maintain full control over their work environment.

Zest is built for independent developers, small engineering teams, and technical leads who regularly work on macOS and want to speed up routine coding and command-line tasks. It's particularly useful for those managing multiple projects or repositories and for teams who value reproducible, shareable workflows that can be tailored per project.

Typical users include software engineers, CTOs, and product-focused developers who already use AI coding tools like Claude or Codex and who wish to streamline their local development environment without sacrificing privacy. Teams who rely on custom scripts, want better context-aware automation, and prefer local solutions over cloud services will find Zest especially appealing.
