Make ad-hoc SQL visible & exportable from DB migrations (date filters, SQL/ZIP)

Many engineering teams lose visibility into ad-hoc SQL that runs alongside formal DB migrations, creating audit gaps and extra work for DBAs, SREs, and compliance officers. This is a broad issue—roughly 20 million dev and engineering teams managing databases encounter mismatches between migration history and real-world SQL, which complicates post-incident forensics and audits. You could build a lightweight platform that hooks into migration tools and DB drivers to capture ad-hoc statements, present them by date range, and export selectable slices as raw SQL or ZIP packages with metadata, checksums, and optional data-redaction. This aligns with three current trends—cloud DB/DBaaS growth, GitOps adoption standardizing schema lifecycles, and increasing regulatory/audit pressure—making it easier to surface and package the missing pieces of change history. With an addressable market of about $4.8B (20M teams × $240/yr) and a revenue potential score of 82/100, modest per-team pricing and enterprise audit features make monetization plausible. To stand out you need provable auditability (signed logs and append-only storage), turnkey integrations for Flyway/Liquibase/Postgres/MySQL and cloud DBs, and privacy-safe export controls; these are clear competitive strengths but require engineering rigor. Competition is medium, and realistic challenges include handling cross-database semantics, permissions in managed DBs, and the operational change required for teams to adopt new capture hooks—targeting compliance-heavy verticals and shipping open-source adapters are practical, lower-friction ways to gain traction.
