GitDelivr

GitDelivr is a free content delivery network designed specifically for public Git repositories. It addresses the challenge of high bandwidth and egress costs associated with cloning large or popular open source projects directly from their origin servers. By acting as a caching layer, the service allows users to clone repositories more quickly, often achieving lower time-to-first-byte than cloning from the original source.

net. On the first clone request, GitDelivr fetches the repository from the origin at full speed and caches the resulting packfile using Cloudflare Workers and Cloudflare R2. Subsequent clone requests for the same repository are then served directly from Cloudflare’s edge network, which consists of over 300 points of presence. This approach reduces the load on the origin server and accelerates access for users worldwide. Branch pointers are cached with a 60-second time-to-live, ensuring that new pushes become visible within about a minute.

GitDelivr leverages the content-addressable nature of Git, ensuring that identical clone requests result in the same cached packfile, and relies on Git’s built-in security: the client verifies every object by hash, so any tampering would be detected and rejected by git fsck. The service is intended to support open source projects, especially those that do not wish to use or cannot use platforms like GitHub or GitLab.

There is no charge for using GitDelivr, and the service is built on top of Cloudflare’s infrastructure. Users do not need to trust the service’s integrity, as Git itself enforces data authenticity during the cloning process.
