## What it is
Rinha de Backend 2025 is the third edition of a community backend coding challenge where participants build a payment-intermediation service that routes requests between two payment processors with the lowest fees while handling service instability. The repository hosts the challenge specification, instructions, and final results.

## Use cases
- practice building high-performance backend services
- compare backend languages and frameworks under load
- learn payment processing failover strategies
- participate in a community backend competition
- benchmark my API against other developers
- study load balancing and fault tolerance techniques

## When to choose
- you want a fun, competitive way to test backend performance skills
- you want to learn resilience patterns like failover and rate handling under pressure
- you want to compare how different stacks perform on an identical workload

## When to avoid
- you need production-ready payment processing software
- you want a library or framework to include in your own project
- the challenge edition has already concluded and you only want active competitions

## Facets
- artifact type: learning-resource
- maturity: stable
- function: benchmarking, load-testing, developer-tools
- domain: backend, developer-tools, performance, education
- platform: self-hosted, cross-platform
- tags: backend-challenge, coding-competition, payment-processing, community-event, brazilian-community, performance-optimization, docker
