Versions:
Ledgerful, published by Ledgerful, LLC, is a local-first command-line tool for deterministic change intelligence, currently at version 0.2.13 across a history of ten recorded versions. The software is designed to bring rigorous, reproducible analysis to the process of modifying codebases, helping developers and engineering teams understand the consequences of changes before and after they are made. Its core purpose is change intelligence: it performs impact and risk analysis to identify what a proposed modification may affect, generates verification plans so that changes can be systematically checked, and attaches signed provenance to code changes so their origin and authenticity can be traced. In addition, Ledgerful builds a local knowledge-graph index of the codebase, giving users a queryable structural understanding of their project without sending data to external services. As a local-first CLI, it fits naturally into developer workflows, scripting environments, and automation pipelines, and it appeals particularly to teams that require auditability, offline operation, or tight control over their source code and metadata. Typical use cases include assessing the blast radius of refactors, planning test and verification coverage for a change set, producing verifiable records of who changed what and when, and exploring dependencies within a repository. Within a software catalog, Ledgerful belongs to the developer tools category, more specifically among command-line utilities for code analysis, software verification, and supply-chain or provenance tooling. The product is source-available under the PolyForm Noncommercial License 1.0.0, which permits noncommercial use, while a separate small-entity commercial exception is documented in the COMMERCIAL-EXCEPTION.md file within the source repository, allowing qualifying smaller organizations to use the software commercially under defined terms. Prospective users should consult the repository for full licensing details and release history.
