derive(Error)
derive(Error) for struct and enum error types
This is a Rust crate that provides a convenient derive macro (#[derive(Error)]) for implementing std::error::Error on your custom error types (structs or enums). The goal is to enable library authors to build expressive, typed error types, with readable Display implementations (via #[error("...")] annotations) as well as From conversions (#[from]), source tracking (#[source]), and optionally backtraces. It is designed so that switching from handwritten error implementation to using this error is not a breaking change: you retain the same API. ... -

Error Prone
Catch common Java mistakes as compile-time errors
...Using Error Prone to augment the compiler’s type analysis, you can catch more mistakes before they cost you time, or end up as bugs in production. We use Error Prone in Google’s Java build system to eliminate classes of serious bugs from entering our code, and we’ve open-sourced it, so you can too. -

react-error-boundary
Simple reusable React error boundary component
react-error-boundary is a tiny, well-tested utility that makes React’s error boundaries practical and ergonomic for everyday apps. It wraps React’s error-handling primitives in a single <ErrorBoundary> component with a predictable API for rendering fallbacks when descendant components throw during render, lifecycle, or event handlers. The library emphasizes recovery, not just failure: you can reset the error state programmatically or when certain “reset keys” change, returning the subtree to a healthy state without a full page refresh. ... -

koa-better-error-handler
A better error-handler for Lad and Koa. Makes `ctx.throw` awesome
Lad is the best Node.js framework. Made by a former Express TC and Koa team member. A better error-handler for Lad and Koa. Makes ctx.throw awesome (best used with koa-404-handler) Detects common programmer mistakes by detecting errors of TypeError, SyntaxError, ReferenceError, RangeError, URIError, and EvalError and yields generic "Internal Server Error" (only applies to production mode). -

Anyhow
Flexible concrete Error type built on std::error::Error
This is a Rust library (crate) that provides a flexible, concrete error type built atop the standard std::error::Error trait. Its primary goal is to make error handling in applications easy: instead of defining lots of custom error types, you can use anyhow::Error (or the alias anyhow::Result<T>) for fallible functions. The crate supports attaching context to errors, so you can convert a low-level error (like “file not found”) into one with richer diagnostics (“Failed to read instructions from path X”) using .context() or .with_context(). ... -

Symfony ErrorHandler
Provides tools to manage errors and ease debugging PHP code
Symfony ErrorHandler is a component that handles and logs PHP errors and exceptions in a structured way. It replaces PHP's default error handling with a more user-friendly and informative system. The component provides detailed error pages for development environments while ensuring minimal disruption in production. It integrates seamlessly with Symfony applications and supports custom error pages. -

Modern Errors
Handle errors in a simple, stable, consistent way
Handle errors in a simple, stable, consistent way. Exporting and documenting all error classes allows consumers to check them. This also enables sharing error classes between modules. Error properties that are internal or secret can be prefixed. This makes them non-enumerable, which prevents iterating or logging them. -

Errbit
The open source error catcher that's Airbrake API compliant
...It is Airbrake API compliant, so if you are already using Airbrake, you can just point the airbrake gem to your Errbit server. The way Errbit arranges notices into error groups is configurable. By default, Errbit uses the notice's error class, error message, complete backtrace, component (or controller), action and environment name to generate a unique fingerprint for every notice. Notices with identical fingerprints appear in the UI as different occurences of the same error and notices with differing fingerprints are displayed as separate errors. ... -

ResultTypes.jl
A Result type for Julia—it's like Nullables for Exceptions
ResultTypes provides a Result type that can hold either a value or an error. This allows us to return a value or an error in a type-stable manner without throwing an exception. -

Whoops
PHP errors for cool kids
...Beyond error pages, Whoops supports custom handlers, logging, and filtering so exceptions can be gracefully transformed or reported. Because it only activates in development by default, it avoids revealing internal application state in production. Developers use Whoops to shorten debugging cycles, reduce the frustration of tracing issues, and maintain cleaner error surfaces across applications. -

Mitiq
Mitiq is an open source toolkit for implementing error mitigation
Mitiq is a Python toolkit for implementing error mitigation techniques on quantum computers. Current quantum computers are noisy due to interactions with the environment, imperfect gate applications, state preparation and measurement errors, etc. Error mitigation seeks to reduce these effects at the software level by compiling quantum programs in clever ways. -

Measurements.jl
Error propagation calculator and library for physical measurements
Error propagation calculator and library for physical measurements. It supports real and complex numbers with uncertainty, arbitrary precision calculations, operations with arrays, and numerical integration. Physical measures are typically reported with an error, a quantification of the uncertainty of the accuracy of the measurement. Whenever you perform mathematical operations involving these quantities you have also to propagate the uncertainty, so that the resulting number will also have an attached error to quantify the confidence about its accuracy. ... -

libtorrent
An efficient feature complete C++ bittorrent implementation
...The main class is the session, it contains the main loop that serves all torrents. Each class and function is described in this manual, you may want to have a look at the tutorial as well. If a torrent hits a disk write error, it will be put into upload mode. This means it will not download anything, but only upload. The assumption is that the write error is caused by a full disk or write permission errors. If the torrent is auto-managed, it will periodically be taken out of the upload mode, trying to write things to the disk again. -

Webmozart Assert
Assertions to validate method input/output with nice error messages
...With these assertions, you can greatly reduce the amount of coding needed to write a safe implementation. This library is heavily inspired by Benjamin Eberlei's wonderful assert package, but fixes a usability issue with error messages that can't be fixed there without breaking backwards compatibility. This package features usable error messages by default. However, you can also easily write custom error messages. In beberlei/assert, the ordering of the %s placeholders is different for every assertion. This package, on the contrary, provides consistent placeholder ordering for all assertions. ... -

View the entire end-to-end distributed trace to see the exact, poor-performing API call and surface any related errors. Breadcrumbs make application development a little easier by showing you the trails of events that lead to the error(s). -

Kreuzberg
Polyglot document intelligence framework
...It emphasizes modular design so that developers can define discrete tasks or “actions” and then compose them into complex flows where dependencies, parallel steps, and error handling are declaratively managed. This structure makes it simpler to build resilient automation pipelines that span multiple technologies or APIs without needing to glue everything together manually. The platform also supports observability and monitoring, helping teams trace the progression of workflows, catch errors early, and evaluate performance trends in orchestrated systems. -

Grape
An opinionated framework for creating REST-like APIs in Ruby
...It provides a DSL for declaring endpoints, parameters, formats, and validation rules, making it easy to build consistent and documented APIs. Grape supports multiple content types (JSON, XML, etc.), versioning, error handling, and authentication hooks, which are crucial for maintaining long-lived APIs. It integrates well with frameworks like Rails or Sinatra but can also be used standalone for microservices. Built-in tools like parameter coercion, strong validations, and automatic documentation (via Swagger integrations) reduce boilerplate and improve maintainability. ... -
