Open Source Modern Treasury Alternatives

Modern Treasury is a payments infrastructure platform built for companies that need to move money at scale without becoming a bank themselves. Instead of integrating separately with each banking partner and payment rail, teams connect once to Modern Treasury’s API and get access to ACH, wire, RTP, FedNow, check, card, and stablecoin payments through a unified interface, backed by a network of partner banks.

At the core of the platform is a programmable, double-entry ledger that tracks every transaction and balance in real time, along with virtual accounts that let businesses issue unlimited sub-accounts for customers or business units without opening new bank accounts. Built-in reconciliation automatically matches ledger entries against bank statements, while approval workflows and KYC/KYB tooling add compliance controls around who can move money and how much.

Modern Treasury increasingly positions itself around stablecoin orchestration as well, letting companies move funds on-chain and off-chain using the same workflows they already use for fiat rails. The platform is used by fintechs, marketplaces, lenders, and payroll platforms — including companies like Gusto, Procore, GoFundMe, and Anchorage Digital — to power embedded payment and banking experiences inside their own products.
