Stop maintaining a ledger. Start shipping product.
The correctness problems that eat your roadmap (concurrency, idempotency, atomic multi-leg postings, audit trails) are solved, in production, open source.
Ship in days, not quarters
Model any flow of funds in Numscript and launch financial features without touching transaction plumbing. Teams cut feature development time on money flows by 40 to 50 percent.
Own everything
MIT-licensed core you can read, fork, self-host, and outlive us with. Evaluate it on GitHub before anyone talks to sales. No black box, no lock-in.
Scale without rewrites
Thousands of transactions per second, horizontal sharding, multi-entity ledgers, and exact-integer math. The edge cases that break home-built ledgers are the baseline here.
A production customer runs 200 billion HTTP requests a month against this architecture; another sustains 500K transactions per month across 14 countries with zero reconciliation errors over 18 months.
Questions, answered
01 / WE COULD BUILD THIS OURSELVES.
You could. The question is whether 12 to 24 months of ledger correctness work (concurrency, idempotency, immutability, recovery) beats building your actual product on a foundation that is already audited and in production. Open source means you keep the control that made building attractive.
02 / HOW DO WE EVALUATE IT?
Clone the repo, run the ledger locally, try flows in the Numscript playground, or take a cloud sandbox. The technical evaluation needs nobody's permission.
Evaluate it like engineers do
Start on the open-source core, or bring your hardest flow to a technical session.
