Open-source business rule engine

Take business rules
out of your code

Let Ordo handle the pricing, risk and approval decisions that keep changing. See what a change affects before you make it, and ship it without a redeploy.

What Ordo does for you

01

Rules in one place

Discounts, limits and risk thresholds stop hiding in code. Business teams can read them, and every change is recorded.

02

See the impact first

Before you move a number, see which decisions change and what they change to.

03

Live without a release

Updated rules take effect right away. Your application code stays the same, with no redeploy.

An example

Change one number, see who it affects

The risk team wants to block payments from a score of 65 instead of 70. After the edit, every test still passes.

Ordo runs the old and new rules side by side and finds 5 cases that move from "add a check" to "block". You decide before the change goes in.

Whether a person or an AI made the change, it goes through the same check.

Block score 70 → 65

5 of 130 cases change

  • Long-time customer, abroad, new phone, paying 5,000

    Check → Block

  • Long-time customer, abroad, new phone, 5 payments in an hour

    Check → Block

The other 125 cases stay the same

Studio

Rules your whole team can read

See the same rules as a flow or as a table. Business teams read the logic, run tests and request releases there. Engineers keep working in the code repository.
