About this product

Sablefish routes incidents to the one person who can actually fix them, using ownership data pulled from your repository rather than a hand-maintained rota. Fewer pages, faster acknowledgement, and an on-call schedule that maintains itself.

Does it handle the case where the code owner is on holiday? That's when our current setup falls over hardest.

Ravi ChandrasekaranVerified

Deriving on-call from CODEOWNERS is one of those ideas that's obvious in hindsight. We maintain our rota by hand and it's wrong within a fortnight, every time.

Marta WiśniewskaMaker

That drift was the original motivation. We fall back to a manual rota when ownership is ambiguous, but it covers about 85% of services out of the box.
