Designed for quick, local work
The utility drawer your Mac should already have.
Wring is intentionally small, native, and private. Open it from any app, process the thing in front of you, copy the result, and get back to your editor. Reorder the tools you use most, switch them with Command-number shortcuts, and avoid browser tabs full of sensitive data.
How it feels
Open. Paste. Copy. Done.
Paste private input locally
Use JWT, JSON, Regex, Hash, Encode, Text, Cron, Color, UUID, Diff, Time, .env, and Load tools without sending data to a website.
Copy the result and move on
Format, verify, convert, compare, generate, clean up, or inspect the thing in front of you, then get back to work.
Toolset
12 built-in toolsEverything is a click away, but nothing is trying to be a platform.

Put your favorite tools in the top tabs and keep the rest inside More.

FAQ
Questions before you install.
Does Wring upload my JWTs, secrets, JSON, or other input?
No. Wring is an offline macOS menu bar app. Tool input is processed locally on your Mac, and the app is built without network client or server entitlements.
What developer tools are included?
Wring includes JWT, Regex, Hash, Encode, Text utilities, JSON, Diff, Time, Cron, Color, UUID, .env Manager, and Load Monitor tools.
Can I customize which tools appear first?
Yes. Wring lets you reorder the top tool tabs from Settings, keep the remaining tools inside More, switch visible tabs with Command + number, and optionally show shortcut hints in sidebar mode.
How does the .env manager store secrets?
The .env manager stores values in the macOS Keychain. Values can be protected with macOS authentication such as Touch ID or your device password.
Does Wring integrate with Xcode, VS Code, Cursor, or other IDEs?
Wring does not need IDE-specific setup. It lives in the macOS menu bar, so it works the same from Xcode, VS Code, Cursor, terminal, browser, Slack, or any other app you already use.
Does the JWT tool validate tokens against a JWKS endpoint?
Wring v1 focuses on local JWT decode, inspection, and HMAC secret verification. JWKS endpoint validation would require explicit network access, so it is being considered carefully as an opt-in, user-triggered workflow rather than a silent background request.
Which macOS version does Wring support?
Wring v1 is built for macOS 26 or later so it can use the newer native SwiftUI behavior the app is designed around.
