JSON, understood.
Inspect · Understand · Transform · Protect
The all-in-one browser workspace to format, validate, score health, diff, redact, and manage JSON without sending a single byte to external servers.
Why Developers Choose JSONForge
Conventional formatters only indent your text. JSONForge provides an intelligent developer environment with health scoring, privacy masking, structural diffs, and local persistence.
JSON Health Score
0–100 quality scoring across validity, depth, type consistency, and anomalies with safe auto-fixes.
Privacy Shield
Detects passwords, API keys, tokens, and PII locally with one-click sanitized copy generation.
Structural Diff Lab
AST-based comparison showing added, removed, modified, and type-changed fields by path.
JSON Time Machine
Visual timeline of meaningful operations with instant snapshot restore, compare, and rollback.
Big JSON Mode
Web Worker offloading and DOM virtualization prevent browser freezing on heavy files.
IndexedDB Workspace
Multi-file tabs, split-pane layout, and automatic crash recovery persisted locally in your browser.
