| Free tier | free and unauthenticated: at least 1 GB RAM with a 2 GB maximum, up to 6 hours of session time or 1 CPU-hour, whichever comes first; no persistent storage of any sort unit hours; metered on wall-clock; The governing limit is one CPU-hour, so six hours of session is only available to an idle kernel. |
|---|---|
| Price | none stated |
| Limits | |
| Binding | volume-quota one CPU-hour is reached in an hour of real work, and there is no disk to keep the result on |
| Identity | anonymous no account and no card: a Binder link runs straight from a public repository. The service logs IP addresses for 30 days for abuse detection. |
| Egress | outgoing bandwidth limited to about 1 mbit per session free allowance: about 1 mbit/s per session |
| Per-object cap | not applicable: the unit is a session, not an object |
| Retention | none: 'We do not offer persistent storage of any sort' |
| Interface | git, rest a Git repository is built into a Docker image and served as a JupyterHub session |
| Tooling | any repo with a requirements.txt or environment.yml; the launch URL is the interface |
| Composes with | a reproducible demo environment for a repo, not a place to compute: one CPU-hour and no disk |
| Reliability | the project states it has no dedicated funding and runs on donated cloud, and it caps launches from most cloud providers |
| Notes | The only anonymous provider, and the only one with a published CPU-hour cap that small. RAM is the project's own 'GB'; whether that is GB is not stated. |
| Evidence note | documented memory, session length, bandwidth and the absence of storage are all quoted from the project's user guidelines today. |
