Big rewrites often fail because teams attempt ‘rewrite everything’ instead of bounded, incremental migrations. Teams lack tooling to automatically identify safe slices, generate migration steps, and coordinate rollout tasks, so rewrites become risky, expensive, and disruptive. This recurring problem affects teams planning migrations from monoliths to microservices or big stack changes.
Why now: Microservices, observability tooling, and richer repository metadata make automated migration planning tractable and reduce organizational risk of large rewrites.
A planner that analyzes dependencies and runtime traces to suggest bounded contexts and low-risk ‘slices’ for incremental rewrites. It automatically generates step-by-step migration plans (compatibility layers, schema migration steps, feature flag rollout plan, required tests, CI gates) and produces a task backlog that integrates with Jira/GitHub and CI pipelines to orchestrate staged rewrites.
Built for: Platform teams, architects, and engineering managers executing large migrations (monolith to services, framework/stack upgrades)
