Before a risky change meets production, prove it on a disposable twin. Built for teams who already feel migration anxiety, staging drift, and release incidents. - 20 to 300 engineers, at fast-growing SaaS and internet companies rather than at regulated enterprises. - Postgres backed applications with enough production data that toy fixtures are misleading. - Daily / weekly production deploys, a real CI/CD process, and a platform engineer who owns reliability. Cloud-native or containerized · customer-hosted agent · history of migration anxiety · production-shaped traffic ## Teams. Postgres, frequent deploys, and a platform engineer who owns reliability. - Seats · billing · rare rows B2B SaaS Daily deploys, expanding schemas, and staging that drifted years ago. Tenant-shaped state without production identities. Open - Stripe offline · fail closed Fintech Billing, ledgers, and side effects that must never hit live processors. A stateful Stripe pack, not the production API. Open - Workers · webhooks captured Marketplaces Queues, workers, dual-writes, and matching logic staging never reproduces. Timing is the bug. Open - Locks · rewrites · plans Developer tools Schema changes on large tables. Users notice p99 immediately. Locks, rewrites and plan regressions show up here first. Open ## Know what happens before you deploy. Create a disposable production twin for every risky change. Catch migration failures before they reach customers.
