Both stand on markdown editors. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Web
Composer combines shared Markdown editing with agent collaboration over MCP. The free plan has specific private-document and upload limits; Pro removes private-document and collaborator limits for the listed prices.

Choose MDedit if you want a free Markdown editor with local file handling, multiple editing views, and offline exports. Its browser sessions cannot open Markdown files directly from disk, and unsigned desktop builds may prompt an operating-system warning.
