Status

This repository contains LedgerForge Core, the open-source ledger engine for self-hosted deployments.

LedgerForge is built for teams evaluating ledger infrastructure locally, then moving toward production deployment when workload, security, and operating requirements are clear. Managed deployment and hosted operations workflows are handled through private onboarding.

The repository preserves upstream Git history and retains the required Apache License 2.0 attribution documented in NOTICE.md.

What LedgerForge Core Provides

• A double-entry ledger for balances, ledgers, transactions, inflight transactions, scheduled transactions, overdrafts, and historical balance snapshots.
• Multi-currency balance tracking for accounts and wallets.
• Transaction workflows including split transactions, bulk transactions, and two-phase commit-style inflight flows.
• Reconciliation primitives for matching external records against internal ledger activity.
• Identity and account models for linking financial entities to balances and transaction flows.
• Webhook, queue, search, metrics, and operational hooks for production financial systems.
• PostgreSQL-backed persistence with Redis-backed queues and operational workers.

Deployment Options

• Self-hosted Core: run LedgerForge locally or on your own infrastructure with Docker, PostgreSQL, and Redis.
• Managed production planning: request private onboarding for workload review, Kubernetes or private-cloud planning, observability, backups, and operating runbooks.

Development

go test -short ./...
make build
docker compose config

go test -short ./... covers the hermetic fast path. Service-backed integration tests expect local PostgreSQL and Redis, which you can start with docker compose up.
