Zag offers AI‑driven agents that run in real macOS and Linux sandboxes to automatically build, test, and review code on every pull request. Developers write agents in TypeScript or Swift to perform code review, UI QA, security penetration testing, and database migration validation, receiving detailed, actionable feedback directly in the PR. The platform provides free and paid plans with shared or dedicated compute environments for development teams building macOS, iOS, or cross‑platform applications.

Problem
Software teams often rely on manual code reviews and separate testing pipelines, which can miss security flaws, UI regressions, or database migration issues before code is merged. This leads to production incidents, increased debugging time, and higher risk of non‑compliance with platform guidelines.
Solution
Zag provides AI‑driven agents that execute in authentic macOS and Linux staging environments for every pull request. Developers write agents in TypeScript or Swift to perform code review, UI QA, security penetration testing, and database migration validation. Each agent builds the application, runs it on realistic device configurations, and reports actionable findings directly in the PR. By integrating the agents into the presubmit workflow, teams receive continuous, automated feedback on functional, security, and compliance aspects without maintaining separate CI scripts. The platform offers shared and isolated compute options, allowing teams to start for free and scale to dedicated, self‑hosted instances as needed.
Target Audience
Primary customers are software development teams building macOS, iOS, or cross‑platform applications who need automated, on‑pull‑request quality, security, and compliance checks.
