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. ... -

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. ... -

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(). ... -

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. -

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. -

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. ... -

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. ... -

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. ... -

OpenVSCode Server
Run upstream VS Code on a remote machine with access
...A few years back, people started patching it in order to run it in a remote context and to make it accessible through web browsers. These efforts have been complex and error-prone because many changes had to be made across the large code base of VS Code. Luckily, in 2019 the VS Code team started to refactor its architecture to support a browser-based working mode. While this architecture has been adopted by Gitpod and GitHub, the important bits have not been open-sourced, until now. As a result, many people in the community still use the old, hard-to-maintain, and error-prone approach. -

go-toml
Go library for the TOML file format
...While go-toml favors usability, it is written with performance in mind. Most operations should not be shockingly slow. Decoder can be set to "strict mode", which makes it error when some parts of the TOML document was not present in the target structure. This is a great way to check for typos. When most decoding errors occur, go-toml returns DecodeError), which contains a human readable contextualized version of the error. TOML supports native local date/times. It allows to represent a given date, time, or date-time without relation to a timezone or offset. ... -

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. ... -

LeakCanary
A memory leak detection library for Android
...It effectively detects leaks and narrows down the cause of each leak through its in-depth knowledge of the internals of the Android Framework. This helps developers avoid and dramatically reduce OutOfMemoryError (OOM) crashes. A memory leak is a programming error that can cause an OutOfMemoryError crash. It’s often caused by bugs related to the lifecycle of objects, and can occur fairly often in Android applications. LeakCanary helps to find and fix those leaks during development so you never have to experience another OOM crash. -
