OP Credit Manager
by 05Haragucci
Players who lend items or currency on the OPSUCHT server can log debts, claims and payments in one place with OP Credit Manager, a Fabric client mod for 1.21.11.
What it does
Credits, debts and deals between players are kept in a GUI inside the game. A deal is created by naming the other player and an amount, and a user can pay, cancel or view it later. Partial repayments are recorded, and a debt can be settled with items, each item stack counting toward the claim at a custom value the user sets, much like a money payment.
Payment messages are detected and saved as paylogs, which can be searched, filtered and paged through. A deal history and statistics overview sit alongside them, and data is kept in a local database on the client, with older JSON data migrated into it automatically. Theme colors and font can be adjusted in the settings, which also control paylog detection and notifications. The author states that functional bugs still occur.
The mod is client-side only, so the server does not need it. It is published for Fabric only, for 1.21.11, and is not open source; it is released under All rights reserved. Source code, an issue tracker and a wiki are linked by the author.
Key features
Debt and claim tracking
Debts and claims between players are created, edited and kept in one overview, so deals do not have to be tracked by hand.
Item payments
Items can settle a debt at a custom value, and a selected item's details are saved for later checks.
Paylog detection
Payment messages in chat are detected and saved as paylogs, with search filters, page navigation and a statistics overview.
Local database
All records are stored locally on the client, and older JSON data is migrated into the new database automatically.

How it compares
OP Credit Manager is client-side only and built for Fabric 1.21.11. PayFilter For Gambling On DonutSMP is also client-side only, uses the MIT License and is for 1.21.11, but it filters gambling payments instead of managing debts. OPKONTOR is client-side only and is also for 1.21.11 under All rights reserved, but it is not a debt manager. None of the three names an open-source status beyond their own licenses.
