This service lets you get a shareable link to download a build artifact from the latest successful GitHub Actions build of a repository.
Any public repository is accessible by default and visitors don't need to log in.
If you'll be publishing a link to your own repository's artifacts, please install the GitHub App anyway, so that downloads for your repositories don't share the global API rate limit. The throttling will likely become very bad over time.
GitHub has no direct way to directly link to the latest build from GitHub actions of a given repository.
Even if you do have a link to an artifact, using it requires the visitor to be logged into the GitHub website.
The discussion originates at actions/upload-artifact "Artifact download URL only work for registered users".
So, this service is a solution to this omission.
Because GitHub doesn't provide any permanent and public links to an artifact, this service redirects to time-limited links that GitHub can give to the application -- only on behalf of an authenticated user that has access to the repository. So, whenever someone downloads an artifact from a repository that you had added, this service uses a token that is associated with your installation of the GitHub App.
This GitHub App requests these permissions:
- Actions: Workflows, workflow runs and artifacts.
- Access: Read-only
- Metadata [mandatory]: Search repositories, list collaborators, and access repository metadata.
- Access: Read-only
Interestingly, the prompt that GitHub presents to you when authenticating to the service says something quite a bit scarier:
nightly.link by Oleh Prypin would like permission to:
- Verify your GitHub identity ($username)
- Know which resources you can access
- Act on your behalf
In reality, this blurb is completely generic and will be shown for any GitHub App authorization regardless of its permissions. This is discussed here.
Furthermore, the permissions that the app asks for are granted even if it's just "installed", without being "authorized".
Verifying your identity is needed so that only you can view links to private repositories and your organizations. Other things, well, the service is not even asking for.
An exhaustive list of what this service stores:
The server of the main instance also keeps access logs and application logs for up to 3 months.
This page will be updated if this changes.
No paid features are currently planned.
This service is developed and run by Oleh Prypin.
It has no affiliation with my employer. No affiliation with GitHub either.
