Tweezr

Tweezr is a system-intelligence platform for safe legacy change, helping banks and insurers understand and incrementally evolve legacy core systems without risky big-bang modernization. The platform maps mainframe and heritage codebases (COBOL, PL/I, CICS, IMS, DB2 z/OS, VSAM, IBM i RPG, Adabas/Natural) into a deterministic, queryable, cited model that grounds engineering teams and AI tools in what the code actually does before anything is changed. Tweezr deploys on-premise by default, is a member of the Banking Industry Architecture Network (BIAN), partners with 10x Banking, is distributed through AWS Marketplace and Microsoft AppSource, and is a Techstars portfolio company. Tweezr publishes no public API or developer program as of July 2026.

Tweezr is profiled on the APIs.io network. Tagged areas include Company, Legacy Modernization, Mainframe, Banking, and Financial Services.

Tweezr’s developer surface includes engineering blog and 8 more developer resources.
