Free · Local-first · Browser accounting
Ledvo is an accounting book that lives in your browser. It stores one book in the browser profile you use for the app, and it uses a real double-entry engine instead of pretending accounting is just a spreadsheet with nicer buttons.
What Ledvo is
Ledvo is a free accounting tool for people who want a real double-entry book without signing up for a cloud service.
It is built for small books, prototypes, learning, owner-managed records, and accountants who want a transparent local-first tool. The current app runs entirely in the browser and stores one book per browser profile and domain using the browser’s private filesystem.
What it does today
- Set up one local accounting book
- Generate starter charts of accounts by entity type
- Create accounts, periods, counterparties, and subledger groups
- Post multi-line journal entries
- Reject unbalanced entries before posting
- Block postings into soft-closed, closed, or locked periods
- Preserve posted entries through voids and reversals instead of edits
- Run trial balance, income statement, balance sheet, general ledger, aging, and equity-change views
- Export and import a portable JSON snapshot
- Work without a login, backend account, analytics, or tracking pixels
What makes it different
Ledvo does not start from a SaaS assumption.
The product model is deliberately smaller:
- The book is local. Your ledger is stored in the browser profile’s Origin Private File System on your device.
- The accounting engine is real. Ledvo uses Heft, an AGPL-3.0-or-later double-entry accounting engine.
- The engine starts on demand. The WebAssembly engine loads when you create, import, or open a book. OPFS stores the ledger file, not the engine.
- The app stays focused. The hosted interface is intentionally small while the app repository remains private during pre-release.
- The claims are narrow. Ledvo is not accounting, tax, or legal advice.
- Exports matter. A local-only tool must let you keep your own backups.
Current limitations
Ledvo is useful, but it is not pretending to be an enterprise accounting suite.
- No hosted multi-user workflow
- No bank feeds
- No payroll
- No tax filing
- No invoice delivery
- No cloud sync
- No formal SOC 2 or SOX attestation
- No guarantee that the current build meets your jurisdiction’s recordkeeping requirements
For serious business use, review the output with a qualified accountant and keep regular exports.
License posture
Ledvo is free to use. The bundled Heft ledger engine is AGPL-3.0-or-later.
The Ledvo app repository remains private while the product is pre-release, so this page does not describe the app shell as open source. Improvements to the accounting engine remain governed by the AGPL-3.0-or-later license.
Availability
The live app is at www.ledvo.app. The apex domain redirects there, and the Vercel fallback is ledvo.vercel.app.
About the developer
Ledvo is built by Jeryl Donato Estopace, an accounting professional turned full-stack software engineer. My background includes fund accounting, financial software support, and building production software. That mix is why Ledvo treats accounting correctness as the product, not an implementation detail.
