About massCode
massCode started as a code snippet manager and now covers more of a developer's daily notes. Snippets are organised in folders with tags, Markdown notes can link to snippets and API requests and be explored as a graph, and notes can carry tasks with status, priority and due dates.
A built-in HTTP client runs saved requests in sequence and passes values between steps. There are also drawings, a math notebook, developer tools, a command palette and an optional AI assistant. Data is stored locally and it works offline.
