Zest

Zest is a productivity extension for VS Code and Cursor designed for developers using AI coding assistants like GitHub Copilot. It automatically monitors AI interactions to help individuals and teams understand their usage patterns, identify inefficiencies, and improve their AI-assisted workflows.

What Makes Zest Stand Out

Zest provides unique analytics for a developer's AI-assisted coding environment. It tracks metrics such as prompts used, time saved, and "stuck" moments where an AI suggestion didn't help. The extension surfaces this data through AI Standups—personalized reports that highlight progress and suggest improvements. For teams, Zest offers Leaderboards to benchmark AI usage and encourage adoption of best practices. A core feature is AI Practices, which are reusable prompts and strategies that developers can create and share within their organization to standardize effective AI workflows.

Who Should Use Zest

This tool is ideal for software development teams actively using GitHub Copilot, Cursor, or similar in-IDE AI tools. It helps engineering managers track the return on investment of AI coding assistants and understand team adoption. Individual developers aiming to refine their prompting and increase their coding efficiency with AI will also find its personal insights valuable.

Frequently Asked Questions

What is Zest? Zest is an analytics and insights extension for VS Code that focuses on AI-assisted coding. Unlike general performance trackers, it specifically monitors how developers interact with large language models (LLMs) inside their code editor, turning raw usage data into actionable recommendations.

How does Zest help improve AI-assisted coding? The tool analyzes your AI interactions to reveal patterns, such as which types of prompts yield the best results or where you frequently get stuck. By highlighting these moments and suggesting proven AI Practices from your team, it helps you refine your approach, potentially increasing coding speed based on its collected data.

Is Zest free or paid? Zest offers a free Developer plan with a 3-day data history. Paid plans, including Pro and Team tiers, provide extended data retention (90 days and 365 days, respectively), advanced team features like leaderboards, and enterprise-grade controls.

What are Zest's main limitations? Zest's functionality is currently tied to specific code editors, primarily VS Code and Cursor. It is designed to measure AI interactions within the IDE, so it may not track usage from other platforms or standalone AI tools. Its value is most pronounced in team environments where sharing practices and benchmarking are priorities.
