# retrofit > retrofit is the foundation under seismic source code and database > schema changes. Co-evolve code and schema safely: ship new features > faster, refactor away schema debt. > > Status: pre-release. Not yet publicly available — this page is a > placeholder while we build in the open. The CLI, its docs, and a full > agent-facing llms.txt land at launch. retrofit is designed to be driven by humans and coding agents alike. When it ships, this file will document the command surface, the JSON output contract, and the stable error codes an agent needs to operate it. Until then, there is nothing to run. ## Stay in the loop - Site: https://retrofit.sh - Get notified at launch: email signup on https://retrofit.sh
