I would add archbee.io since it's a notes app MADE for developers.
With Markdown support, GraphiQL, SwaggerUI, changelogs, embedded VS Code, Slack, Github, Trello integration.
Disclaimer: I am the founder of Archbee.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
