Your AI stack needs an escape route.
HOTSPARE is testing a simple promise: if a critical model became unusable tonight, your team should already know what it can switch to, what will change, and when that fallback was last proven against your workload.
Discover
Inventory model dependencies in code and map them to current provider lifecycle information.
Prove
Test candidate replacements against representative workload contracts instead of assuming “newer” means compatible.
Prepare
Keep the evidence and migration path ready before lifecycle churn becomes an incident.
Free dependency health check
The first product test is intentionally small: scan a repository, identify lifecycle exposure, show exact affected locations, and separate provider-recommended replacements from what still needs workload-specific validation.
For public repositories, send the URL. For private repositories, contact us first and we will agree on a read-only review path. HOTSPARE is in validation. A health check is engineering evidence, not a guarantee that any replacement is safe for production.
