Lerian is a complete, modular core banking platform. Each product is a modular building block that delivers end-to-end capabilities for a specific financial domain. Products can be adopted individually or combined into a composable ecosystem. Midaz and Fetcher are source-available under the Elastic License 2.0 (ELv2). The other Lerian products are closed source and available to licensed customers, with their repositories maintained internally.

Products, platform, and Brazil Rails


Midaz

Create ledgers, manage transactions, and use core entities like accounts and assets — with CRM and the Fees Engine built in as part of Midaz. Connect rails like Pix and TED.

Reporter

Generate and download reports from reusable templates, filter their data, and manage recurring reporting deadlines. Supports HTML, XML, CSV, PDF, and TXT output.

Matcher

Validate external transactions against the ledger and surface mismatches. Built for accuracy, traceability, and automation.

Flowker

Orchestrate transaction flows using validations, approvals, and external triggers with logic and plugin coordination.

Tracer

Validate transactions in real time, apply rules and spending limits, and return ALLOW, DENY, or REVIEW decisions.

Fetcher

Connect to external databases and extract data on schedule, feeding Reporter, Matcher, and your own services. Source-available, like Midaz.

Lender

Run the credit journey end to end — loan products, origination, servicing, accounting, and Brazil-first regulatory support.

Streaming Hub

Consume platform events and fan them out to your systems through signed webhooks, queues, or a pull API — the platform’s event delivery edge.

Platform

Use shared services for access, lifecycle management, observability, and deployment across the products you adopt.

Brazil Rails

Reach Brazil’s payment and regulatory rails through partner integrations and Lerian native messaging.
