Deep merge JSON objects in browser. 100% client-side.
JSON Merge: Deep merge JSON objects in browser. Use when consolidating configs from different environments, combining partial API responses, or unifying data sources. Privacy by design: all computation is local. Your input is never seen by any server. Find it with the other JSON tools at HttpStatus.com.
By default, later values override earlier ones. Some tools offer merge strategies like append or skip.
Client-side tools use your device's memory, so they handle up to several megabytes. Very large inputs may slow the tab.
No installation, works on any device, and results are shareable via URL. CLI tools are still better for CI/CD pipelines.
