## What it is
Eris is a Go error handling library providing readable stack traces, error wrapping, and flexible output formatting including JSON. It integrates with Sentry and offers alternatives to pkg/errors.

## Use cases
- add readable stack traces to Go errors
- wrap errors with context in Go applications
- format errors as JSON for structured logging
- send error traces to Sentry
- migrate from pkg/errors to a maintained alternative

## When to choose
- you need detailed, readable stack traces in Go
- you want flexible error output formats including JSON
- you use Sentry for error reporting

## When to avoid
- you only need Go 1.13+ standard error wrapping
- you want a zero-dependency minimal solution

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, logging
- domain: developer-tools, backend
- platform: go
- tags: stack-traces, error-wrapping, sentry-integration, json-formatting, golang
