What Bridger Does
A purpose-built desktop tool for teams who plan and execute database-to-database migrations professionally.
Bridger
Everything you need to take a migration from raw schema to a validated, documented mapping deliverable.
Flexible ingestion
Import source and target schemas from CSV exports, DDL scripts, JSON schema files, or Excel spreadsheets. Bridger normalizes all formats into a consistent internal model.
Structured mapping workspace
Organize mappings by target table with full column-level detail — transformation logic, status, indicators, notations, and source group relationships all in one place.
Shared logic library
Store reusable transformation patterns and logic templates in a central library. Push updates downstream to any project that references a library item.
Complex source modeling
Define many-to-one source relationships where multiple legacy tables feed a single target. Model joins, unions, and lookups as first-class mapping constructs.
Local LLM integration
Connect Bridger to a local Ollama model to generate column mapping suggestions and review transformation logic without sending your schema data to external services.
Client-ready deliverables
Generate formatted Excel reports and custom report templates directly from your workbook. Export validation SQL scripts in your target database dialect.
What's coming
Bridger is actively developed. Features in progress include enhanced auto-mapping rules, expanded dialect support, and deeper reporting customization.
