17 days until the October 23 OpenAI shutdowns
Find the OpenAI dependencies that can break before your users do.
Finding an old model name is easy. Finding what breaks after you replace it is the real problem. Sunset scans a repository for scheduled OpenAI shutdown risk and shows the severity before you pay.
Free scan first. Upgrade only if you want the exact files, lines, shutdown dates, official guidance, and migration checklist.
Read-only scanning · Does not execute repository code · Does not modify repositories · Stripe-verified payment · Official OpenAI deprecation source

Free scan
$0.00
Severity counts for the repository. Files, lines, identifiers, shutdown dates, and migration steps stay in the paid report.
One-time
Migration Report
$49.00
One verified Checkout Session unlocks a downloadable report for that repository: files, lines, official dates, classification, documented replacements, risks, and a checklist.
Subscription
Continuous Monitoring
$19.00/month
While the Stripe subscription is active, a new request can scan the same repository again. Canceling stops new checks. Sunset does not open pull requests, and a monitoring check does not rewrite a purchased Migration Report.
