Binder provides shareable, interactive computing environments that can be launched from publicly available code repositories.
What Binder is
Binder provides shareable, interactive computing environments that can be launched from publicly available code repositories. BinderHub builds an environment image and starts a Binder service; documented repository sources include GitHub, GitLab, and GitHub Gist. JupyterLab is the default interface, with the classic notebook also available. Examples cover Python, R, Julia, and Octave, as well as browser sessions for RStudio, Shiny apps, Voilà dashboards, and Bokeh apps. The free public mybinder.org service requires no login and is intended for interactive, temporary coding, not as the backend for for-profit products. Sessions aim to last up to six hours or one CPU-hour for intensive work, but ongoing availability is not guaranteed. Users are guaranteed at least 1 GB of RAM and may receive up to 2 GB; sessions shut down after more than 10 minutes of inactivity. There is no persistent storage, and session contents are destroyed after logout or inactivity. The stated maximum is 100 simultaneous sessions per repository. Binder can also be self-hosted.
Good
- Free public service with no login required
- Launches repositories from GitHub, GitLab, and GitHub Gist
- JupyterLab and classic notebook interfaces are available
- Examples include Python, R, Julia, and Octave
Watch out
- No persistent storage; session contents are destroyed
- Sessions shut down after more than 10 minutes inactive
- Session duration is not guaranteed
- Maximum 100 simultaneous sessions per repository
Who it suits
Binder suits people who want to share or explore temporary, interactive coding environments from public repositories. It is also an option for users who want to self-host the service.
Verdict
Binder is designed for temporary browser-based coding, with support for several repository sources and notebook interfaces. Its lack of persistent storage and session limits make it unsuitable when work must remain available after a session ends.
