An AI code editor that checks its own work
Open-source AI code editor. Composer plans a change and stages it as a diff. Before you apply it, every change is checked: it parses, imports resolve, types check, the preview renders, and tests run. Tests run in your browser tab, free.
Aperture is an open-source AI code editor that stages changes as diffs and verifies them through parsing, type checking, and testing before application. It allows tests to run directly in the browser, providing a streamlined development experience.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
