24 alternatives to A tool to visualise Zod validation errors
I work on code generator that creates TypeScript SDKs from OpenAPI specs and Zod (https://zod.dev/) is a critical building block that I chose to power runtime validation in those SDKs. Depending on the complexity of a Zod schema, the resulting validation error message can contain a wall of JSON text - the serialised issues that were recorded during validation. I wanted to try and create a small tool to help me better visualise and parse these errors. In code and the command line, we do also have the ability to pretty-print the errors but I still wanted a web UI which can let…
This tool visualizes Zod validation errors in a web interface, making it easier to read and understand error messages generated during runtime validation. It's designed for developers working with TypeScript SDKs built… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hey, I'm Martyn and I recently joined Zuplo. OpenAPI is a huge part of what we do, but getting a document up to scratch out of the gate, especially if you're not super well versed in the actual specification and what you should use and when. So we built a suite of tools to help with this called Rate My OpenAPI. It will score your OpenAPI document out of 100, as well as giving you individual scores in 4 key areas; completeness, SDK generation, security and documentation. Along with the score, you also get details of what the issues, or errors are, as well as guidance on what they actually…

Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different…

Stack Error is a pragmatic error handling library for Rust that provides helpful messages for debugging, and structured data for runtime error handling. Features: * Informative error messages: stack error messages and optionally add file/line context to your messages. This helps convey not just what went wrong, but also how it went wrong, making debugging faster. * Programmatic error handling: include optional error codes and URIs for robust runtime handling. * Library-Friendly: define custom error types easily while staying compatible with Rust’s error ecosystem. If designing good…

Hi HN! I built dhi, a data validation library that uses Zig to compile to both native C (Python) and SIMD WASM (TypeScript). Key points: - Drop-in API compatibility with Pydantic (Python) and Zod (TypeScript) - Python: 24.9M validations/sec (520x faster than Pydantic V2) - TypeScript: up to 77x faster than Zod on invalid data - 28KB WASM bundle, zero JS runtime overhead I'd love feedback on the API surface, benchmarks, and real-world integration pain points. If you're curious, the repo has full benchmarks and examples.

For the past few months we’ve been building a simple jest/typescript-based high-level language for writing and running integration tests. We're open-sourcing it now and are excited to share it with you: https://github.com/traceloop/jest-opentelemetry Why we built this: - There are many solid frameworks for FE / browser testing, but none with high-level constructs for testing BE flows - We were missing a way to validate side effects for complex backend systems, especially across async queueing systems Our beta version lets you send an API call to a system and…
