About DevBox
Small tools for everyday developer tasks.
DevBox is a growing collection of focused utilities for developers, including JSON, Base64, URL, HTML entity and JWT workflows.
Why DevBox exists
Developer tools should be quick to understand and quick to leave. DevBox keeps each workflow focused, explains errors in plain language, and avoids requiring an account for simple tasks.
The current JSON tool processes pasted text and uploaded files in your browser. That makes it useful for inspecting API responses and configuration while keeping the data on your device during normal use.
What you can use today
Open the JSON viewer and formatter to inspect and validate payloads, or use the encoding and decoding tools for Base64, URL components, HTML entities and JWT claims. The CSS and frontend cluster is marked as coming soon while it is being built.
