Quick guide

Kyane

Kyane lives in your menu bar, and on your command line if you want it there, and helps you format, inspect, decode, transform, convert, and compare developer data locally, without sending pasted content to a web tool.

  1. Open Kyane

    Press Cmd+Shift+J from anywhere, or click the Kyane icon in the menu bar. macOS hides menu bar icons when the bar is full, so the shortcut is the reliable way in. Kyane reads the clipboard when it opens and never monitors it in the background.

  2. Choose or confirm a tool

    Kyane detects confident inputs automatically and suggests likely tools when the match is less certain. Choose a tool manually when the input is unknown or you want a different operation.

  3. Run the local action

    Format, validate, decode, parse, hash, convert, or compare the input with the selected tool. Review the output, warnings, and inspector details, then copy the result with best-effort secret masking enabled by default.

  4. Reuse work without repeating it

    Restore best-effort-masked results from memory-only session history, chain actions into saved workflows, process supported files in a batch, or send selected text through the Process with Kyane macOS Service. A few interactive actions, such as Diff compare and Regex evaluate, run in the workbench rather than as workflow steps.

  5. Take it to the terminal

    Install the CLI from Kyane and pipe data through it offline: kyane detect, kyane run --tool json --action Format, and kyane recipe to replay a saved workflow. A .kyane.json project profile carries that project's workflows and its own list of sensitive keys to mask, so a repository can keep its conventions with it.

  6. Unlock the full toolbox

    Pro

    With a license, use YAML, CSV/TSV, HTML, HTTP Headers, .env, Regex, JS Expression, SQL, Diff, and cURL tools, including their eligible batch, workflow, and CLI steps.

What's included

Free

  • JSON validation, formatting, minifying, conversion to YAML, CSV, XML, query strings, and .env, schema validation, sample generation, and Swift Codable generation from either a schema or a sample payload
  • XML validation, formatting, minifying, and JSON conversion
  • Base64 encode and decode
  • URL encode, decode, parse, tracking-parameter cleaning, query sorting, and query-data conversion
  • Timestamp conversion to local date, UTC date, Unix seconds, and Unix milliseconds
  • JWT parsing, claim validation, expiry countdown, and HS256 signature verification with a shared secret you supply
  • MD5, SHA-1, SHA-256, and SHA-512 generation and comparison
  • Memory-only session history, saved workflows, project profiles, and the offline CLI, with each step still following its own tool's tier
  • JSON and XML batch processing, plus Process with Kyane macOS Service actions that follow the detected tool tier

  • cURL parsing, redaction, routing, and Swift, JavaScript, Python, and Go client generation
  • YAML, SQL, CSV, and TSV batch processing

Pro unlocks with any license · annual and lifetime unlock the same features

Good to know

  • Kyane processes tool input locally, in the app and in the CLI alike. Network access is reserved for license activation, license verification, and update checks.
  • Session history stays in memory, stores best-effort-masked content, and is cleared with the workspace or when the window closes.
  • JWT parsing, claim validation, and expiry countdown read a token without checking its signature. Only Verify HS256 verifies one, using the shared secret you paste, which never leaves your Mac.
  • The CLI, workflows, and project profiles are free. A step that uses a Pro tool still needs a license, and the CLI exits with a distinct status when it hits one.
