Open Source Infrastructure for the Financial Internet
Formance Platform is building open-source infrastructure for the next wave of financial services. It enables fintech engineers to build and operate complex flow of funds, weaving together multiple payment rails with internal ledger accounts. github.com/formancehq/stack
Formance provides an open source, programmable core ledger that unifies fiat and digital assets, enabling real-time tracking, auditability, and automated financial flows across multiple rails. It offers a self-hosted, extensible platform with connectors, flows, and reconciliation to reduce data drift and accelerate fintech development.
Formance offers a double-entry core ledger with a purpose-built Numscript language for money, multi-asset tracking, and a modular toolkit: Ledger (multi-currency, double-entry), Connectivity (ingest across banks, payment rails, wallets, exchanges, custodians), Flows (end-to-end fund lifecycle orchestration), and Reconciliation (automated drift detection and reconciliation). It provides pre-built connectors (Stripe, Adyen, Wise, etc.), a Wallets module, and a Reconciliation module, all deployable on customer infrastructure (open source under MIT) or via enterprise deployment with private cloud or self-hosted options. The platform emphasizes real-time balances, end-to-end traceability, and audit-ready reporting, with deployment in customers’ own cloud and open-source transparency.
Who it’s for: Financial services technology teams building or operating fintech products that manage multi-currency/off-bank ledgers, payments, and complex fund flows.
Open Source offering available; Enterprise deployment with custom quote; Pricing page indicates ongoing development and productization; multiple modules and connectors showcased.
