A project aiming to consolidate and standardise comparisons of schema validation libraries.
Runtime benchmarks are run in sequence, on a GitHub runner. There are different types of benchmark:
- Initialization: Creating the schema itself. This is usually a one time cost.
- Validation: Checking if a given value matches the schema.
- Parsing: Checking if a given value matches the schema, and returning a new value. This will include any transformations.
Some libraries only support validation, or parsing. In these cases, we categorise them accordingly.
Each library is benchmarked against a set of data, both valid and invalid.
Download benchmarks are created by compiling example usage files with Rolldown, and measuring the size of the output, both minified and unminified.
This monorepo is split into 4 main parts:
The schemas and benchmark definitions for each library, and the data used.
If you're looking to add a new library, this is most relevant.
The website for displaying results, built with TanStack Start. Deployed at schemabenchmarks.dev.
Node scripts to consume and run the benchmarks, and the results.
Simple utilities that might be useful in multiple places, that aren't worth depending on a specific library for.
