The code is open. Your data is yours.

The core is LGPL and free to run yourself. Paid plans license the OneYukti apps for the term. Either way you can export everything, any time.

Why open source matters for business software

Business software holds your books, your customers, your staff records and your stock. The software that runs your business should be software you can read, change and control.

Auditability

Every line of code is visible. Anyone you trust can read exactly what the software does with your data. No hidden telemetry, no logic you cannot inspect.

No lock-in

If you decide to move, you take your data and your customizations with you. You control the code and can run it anywhere.

Change what you need

Modify any module, build new ones, change a workflow. The only boundary is what your business needs.

Community-tested quality

Bugs get found sooner. Features get tested across more businesses. A global community produces software that no single company could build alone.

What is written down

The licence, the edition and the exit are stated here, and the same words are on your quote.

  • The core is LGPL-3.0 and free to run yourself.
  • OneYukti Community is self-hosted and free.
  • Upgrade scripts are published. On a paid plan, upgrades are included for the term.
  • Export everything, any time.
  • The end-of-term terms are on your quote.

"If you don't own and host the database, software and files, you are completely at the mercy of your software providers in so many ways."

Source code

The OneYukti core is published under LGPL-3.0. Until the public repository link is confirmed, ask us and we send it by email.

Built on the Odoo Community codebase

OneYukti is built on the Odoo Community codebase. We do not pretend otherwise. What we add is on the pricing page.

Why source access matters more than a feature list

Tally, Marg, Busy and Vyapar are closed: no source access, no data model to extend, customization limited to whatever the vendor built in. See what that means in practice and what an open codebase makes possible.
