LedgerForge Core is an open-source toolkit that gives developers everything they need to build ledgers, automate reconciliation, and manage identities with ease.
LedgerForge’s ledger is built on a double-entry accounting model designed for precision, scalability, and traceability. Each transaction is recorded as a balanced entry between a source and destination, ensuring data integrity at all times.
LedgerForge enforces double entry by requiring every transaction to have both a source and a destination. This means each transaction always involves two parties, keeping your records balanced.
Yes. LedgerForge Core supports multi-currency by letting you define balances in different currencies and track them independently within the same ledger.
Yes, you can. Define how money moves in your system and implement them in LedgerForge via API calls. LedgerForge handles all of the ledger logic under the hood.
LedgerForge is designed to handle high volume transactions and workflows. Run the open-source Core locally or in your infrastructure and enjoy high throughput backed by highly optimized concurrency controls.
LedgerForge Core uses Postgres as its storage engine. You get to bring your own Postgres database giving you 100% control on your data.
Managed Cloud is currently private access. Request a managed pilot, share your workload and hosting needs, and we will provision the workspace link after onboarding.
LedgerForge is API-first. Run the open-source Core locally or in your infra, then connect through REST APIs or SDKs.
Yes. Everything in LedgerForge is driven by APIs. You can wrap workflows in your own services, extend them with business rules, or connect them to any provider.
Yes, you can. You can start by running LedgerForge alongside your current system. Import balances, replay historical transactions if needed, and phase over workflows step by step.
