Every API you build on has an expiry date. Your client repos never get the memo.
Shopify, Stripe, Google Ads, Meta, Twilio, the AI SDKs — every provider sunsets old versions and deprecates fields on its own schedule. Sunset watches every repo you point it at, finds what's about to break across all of them, and opens a tested draft PR before the date lands.
No silent auto-merge. Every migration is test-verified and every PR is a draft, waiting on a human to approve it.
The API changed. You found out from a client.
Every provider you integrate runs its own deprecation clock. Payment APIs retire versions, ad platforms rename fields, commerce APIs force-sunset old endpoints, the AI SDKs change response shapes between releases. When one of them lands on code that still calls the old way, requests start failing. Usually you find out from a client, not from the provider.
That's manageable for one integration. It's not manageable for the client book. An agency running thirty, fifty, eighty client repos has some version, some field, some endpoint going stale across some provider somewhere in that portfolio at any given time, and nobody's job is to track all of it. So it gets found the way most integration breakage gets found: in production, after it's already cost someone money.
How it works
Sunset connects to your GitHub org and reads the repos you point it at. It works through the parts most tools miss, then hands you a PR you review like any other.
Find every call, even the wrapped ones
It finds every place your code calls an external provider's API, and which version each call is pinned to, including calls buried a few layers deep in your own service wrapper. An AST parser follows the call graph; regex would miss them.
Match against the real sunset schedule
It matches those call sites against each provider's actual deprecation and sunset schedule. Not "is there a newer version out" but "does your code touch the specific field or endpoint that's changing."
Write the fix and prove it
When something's going to break, Sunset writes the migration, applies it in an isolated branch, and runs your test suite against the new version. Green tests are the gate.
Open a draft PR you review
You get a draft PR with a plain-English report: what breaks, when, why, exactly which call sites were touched, and whether the tests passed. You review it like any other PR from a teammate. Nothing merges without you.
The Portfolio Drift Board
One rare event per repo is easy to ignore. Across forty client repos and a dozen providers, something is always drifting. This is the thing you check on a Monday instead of finding out on a Friday, every client, every provider, ranked so the worst deadline is at the top.
| Client repo | Provider | Status | Deadline |
|---|---|---|---|
| havenwood-interiors | Shopify Admin 2025-07 | BREAKING | 6 days |
| northfield-payments | Stripe 2025-08-27 | BREAKING | 23 days |
| lumen-growth | Google Ads v18 → v19 | DRIFT | 61 days |
| fettle-social | Meta Graph v21 | DRIFT | 96 days |
| orchard-notifications | Twilio 2010-04-01 | VERIFIED | — |
One tool, every provider you don't control
Sunset isn't a Shopify tool. It's built for the whole surface of third-party APIs your code depends on but can't pin down. Shopify is live today; the rest are laddered in the order agencies feel the pain. Want one moved up? Tell us.

It never merges itself.
Sunset doesn't auto-merge and it doesn't touch your production secrets. Every migration runs against a test environment pinned to the new API version before a PR ever opens, and every PR is a draft, waiting on a human to approve it.
If a call site is ambiguous, Sunset flags it as low-confidence and says so, rather than guessing. We'd rather be a tool you trust than one that's fast and occasionally wrong in your prod branch.
