We merge to main behind a flag and turn it on when it’s ready. Release branches went away, and so did the Friday merge freeze.

We ran 31 experiments in Flipside last quarter, up from four. The pricing page test alone paid for the contract twice.

Flags evaluate locally from a cached ruleset, so there’s no network hop in the hot path. That was the dealbreaker for us.

I can show two versions of onboarding to 5 percent of new signups and have an answer by Friday, without filing a ticket.

When the new editor spiked our error rate, we turned it off in eleven seconds. Nobody had to deploy anything.
