Why You Can Trust G2's Software Rankings:
G2's software rankings are built on verified user reviews, rigorous moderation, and a consistent research methodology maintained by a team of analysts and data experts. Each product is measured using the same transparent criteria, with no paid placement or vendor influence. While reviews reflect real user experiences, which can be subjective, they offer valuable insight into how software performs in the hands of professionals. Together, these inputs power the G2 Score, a standardized way to compare tools within every category.

Worthune is a catalog of financial planning models delivered as a REST API, an MCP server, and embeddable calculators. Each model is written to a versioned public specification and is Concordance-tested: a second implementation, written independently in a different language from the spec alone, must agree with the production engine on 250 cases per model - to one part in a billion - before any release. The harness runs in CI on every change, and a mismatch stops the release. Every response carries the spec version, the government constants it used with their primary sources and check dates, and a SHA-256 decision record you can store and recompute later to prove where a number came from. Built for developers adding financial math to fintech, wealthtech, and banking products; for teams that must show a compliance reviewer where a number came from; and for AI agents that need deterministic financial computation instead of predicted digits. Official SDKs are published for JavaScript (npm i worthune) and Python (pip install worthune), both zero-dependency, and the open eval datasets are on HuggingFace. Three models are free to call with attribution, with no signup and no API key. Pro is $199/month for the full catalog, with no per-run metering. Worthune models are illustrative planning tools, not financial advice.
