BizLogicLens – Visualize and assess business logic in the database

Map business logic buried in thousands of stored procedures so teams can safely change them

Problem

Many legacy systems keep almost all business logic inside SQL stored procedures—thousands of them—calling each other, causing frequent deadlocks. Nobody understands the whole flow, so everyone is afraid to touch it. New developers face a tangled mess with high risk.

Solution

An analysis tool that automatically parses stored procedure dependencies in a database, generates an interactive call graph, and flags high-risk nodes (circular calls, high-lock tables, long-running procedures). It supports change impact analysis so you know what will be affected before you modify anything.

Users

Backend developers, tech leads, and DBAs maintaining legacy systems

MVP

Connect to PostgreSQL/SQL Server to read stored procedure definitions; static dependency analysis and call graph generation; flag circular dependencies and frequent lock conflicts; export impact reports

Revenue

Subscription tiered by database instances or number of stored procedures; enterprise version for private deployment

Why now

Many old systems still run on stored procedures, and AI coding assistants handle this poorly—developers need dedicated tools to understand and safely refactor, making this a niche an indie developer can own with database parsing skills
