Stage Diff

Typical situation: you’re about to promote staging to production and want to check they actually match. Also good for auditing what a long-running PR preview has that production doesn’t, or tracking down stale resources.

Usage

$ wd diff staging production
  Diff: staging vs production

  Resources:
    = payments-db (d1) — same
    + cache-kv (kv) — only-in-a
    ~ token-kv (kv) — different

  Workers:
    = workers/api — same
    + workers/experiment — only-in-a

  Secrets:
    ~ workers/api/STRIPE_KEY: staging=set, production=set

The symbols: = same in both, + only in the first stage, - only in the second, ~ exists in both but different.

Machine-readable output

$ wd diff staging production --format json
{
  "resources": [
    { "name": "payments-db", "type": "d1", "status": "same" },
    { "name": "cache-kv", "type": "kv", "status": "only-in-a" },
    ...
  ],
  "workers": [...],
  "secrets": [...]
}

Pipe this into jq or your own tooling for automated promotion checks.
