ToolbitText Diff and Compare Tool
Put two versions of a config file, a response body, or a document next to each other and see exactly what changed. Nothing is uploaded, so comparing production config is safe.
What the Text Diff Tool does
- Side-by-side and inline diff views.
- Line-level and word-level highlighting of changes.
- Optional whitespace-insensitive comparison.
- Works on config files, API responses, logs, and prose.
How to use it
- Paste the original text on the left.
- Paste the changed text on the right.
- Read the highlighted additions and deletions.
Why it runs locally
Toolbit has no backend. The Text Diff Tool is implemented with standard browser APIs, so your input is processed in the tab and never uploaded, logged, or retained. That is what makes it safe to paste real data into — and it is also why the tool keeps working with the network disconnected, once you have installed Toolbit as an app.
Frequently asked questions
- Can I ignore whitespace differences?
- Yes. Whitespace-insensitive mode hides reindentation so you only see substantive changes.
- Is it safe to diff production config?
- No. Every Toolbit tool runs entirely in your browser using standard Web APIs. Your input is never uploaded, logged, or sent to a third party — you can open the network tab and watch it stay quiet.
- Does it show word-level changes?
- Yes. Changed lines are highlighted down to the individual words that differ.
