September 2026 Summaries

Convex DevX Engineer Mike Cann introduces Convex Explained, a new site of interactive, text-based tutorials intended to serve both human readers and AI agents. The format aims to combine the accessibility of written documentation with hands-on demonstrations that users can click through, modify, and explore at their own pace, while companion videos remain available for viewers who prefer them. Its first explainer, Build Your Own Convex, guides users from a basic JSON file through the database concepts needed to construct a system resembling Convex, emphasizing that Convex is its own database rather than a PostgreSQL wrapper and illustrating issues such as concurrent purchases and the need for transactions. Cann describes the initiative as an experiment because interactive explainers require more effort than conventional posts, invites feedback on the format and future topics, and notes that an explainer about Batch Worker is already in development.
