Below are benchmark results for several node.js JSON validation modules.

This is an update to a post I made 6 months ago.

Dec 2014 Update: Added 'revalidator' and updated module versions.

The following modules are benchmarked:

• is-my-json-valid 1.3.7https://github.com/mafintosh/is-my-json-valid
• amanda 0.5.1https://github.com/apiaryio/Amanda
• jayschema 0.2.8https://github.com/natesilva/jayschema
• json-gate 0.8.21https://github.com/oferei/json-gate
• json-schema 0.2.2https://github.com/kriszyp/json-schema
• JSV 4.0.2https://github.com/garycourt/JSV
• schema 0.2.1https://github.com/akidee/schema.js
• tv4 1.1.5https://github.com/geraintluff/tv4
• z-schema 3.2.0https://github.com/zaggino/z-schema
• revalidator 0.3.1https://github.com/flatiron/revalidator

All modules validate with the JSON schema described here: http://json-schema.org/

I used the latest schema version supported by each module. This is noted as (v2) (v3) or (v4).

20,000 valid and 20,000 invalid JSON objects were pre-generated with random data. Each validator module was tested against the same randomized objects.

Results - Valid Objects

Results - Invalid Objects

Conclusion

is-my-json-valid is the fastest validator for both valid and invalid objects.

It's so fast I had to make sure it was actually doing anything at all. Amazingly fast!

tv4 is still plenty fast validating valid objects but is a bit slow dealing with invalid ones.

Jayschema remains the slowest validator.

Lastly, a reminder, amanda only supports async validation and so that test includes some additional overhead in dealing with callbacks.
