Versioning · deterministic CI
Pin it once. The data never drifts.
Pinned, reproducible universes for CI. A snapshot regenerates byte-identically on every request, so pinned tests never drift.
01 / Two modes
Live vs. snapshot.
- Live — the
gh./slack./sentry./circleci./zendesk./gl./bb./ado./jira./linear./anthropic./cursor./devin./openai./chatgpt./graph./pd./sf./hubspot./buildkite./statuspage.hosts serve a continuously-fresh universe (newest activity within a day). Great for exploration. - Snapshot — a pinned
*.snap.host serves a reproducible universe that regenerates byte-identically on every request. Great for CI.
02 / Pinning
It's a hostname swap.
Point your client's base URL at a snapshot host instead of the live host — nothing else changes.
# One pin, one base URL. Every other pin is the same swap.
export GITHUB_BASE_URL=https://gh-2026-03-g11.snap.sandboxapis.dev
# The whole list, machine-readable:
curl -s https://api.sandboxapis.dev/v1/snapshotsPins come in generations. A generation is a whole frozen universe, not a feature flag: generation 2 (the -g2 hosts below) serves repository files; generation 1 predates them. The two hold different data — different issue keys, different commit SHAs — so pick one and stay on it. The table below groups every pin by provider, and the generation filter answers the question people actually arrive with: give me every host on one generation.
