THE WORKBENCHES
Sixteen focused utilities for converting, inspecting, generating, comparing, and debugging developer data on your Mac.
01 / STRUCTURED DATA
Convert, inspect, and prepare data for the next step.
Turn dense JSON into readable, useful output. Format, minify, validate, apply supported repairs, and query with local jq.
Free: Run any supported jq query with Run or Return, then view, select, copy, or save the result.
Pro: Live jq and autocomplete suggestions while you write.
Move between JSON and YAML, with formatting controls and useful diagnostics when an input needs attention.
Encode and decode UTF-8 text using Base64, Hex, Base32, Base58, or Ascii85. Adjust relevant alphabet, padding, and strictness options.
Turn a local image into a data URI, resize supported raster images, and copy ready-to-use HTML, CSS, or Markdown.
02 / REQUESTS & TOKENS
Inspect tokens and URLs, and turn curl commands into code.
Read token claims, inspect time-based values, and verify or create HMAC and RSA signatures using locally supplied key material.
Free: Decode tokens and inspect claims, time analysis, security warnings, and expected-algorithm results.
Pro: HMAC and RSA verification, token encoding and signing, and Encode helpers.
Inspect a curl command and generate built-in HTTP client functions for Python, JavaScript, Go, or Java. Run curl when you explicitly choose to.
Inspect a URL’s parts, edit query parameters, redact sensitive-looking values, and rebuild a copyable URL.
Free: Complete local parse, edit, rebuild, redact, inspect, copy, and external Open workflows.
Pro: Embedded Web Preview and its controls.
03 / TEXT
Understand a pattern, a match, or a change.
Test Swift/Foundation regular expressions, inspect matches and captures, preview replacements, and export match data or code snippets.
Free: Complete bundled-example workflows with results, replacement, tests, inspection, copy, and export.
Pro: Custom pattern, test-text, and replacement input.
Compare two text sources locally and inspect their differences while keeping both original inputs editable.
Free: Line comparison through 128 KiB of combined UTF-8 input, with every result layout, option, inspection, and copy action.
Pro: Larger bounded comparisons and Word or Character precision.
04 / LOCAL DATA
Explore structured data and diagnostic logs on your Mac.
Open CSV, TSV, NDJSON, or supported JSON files as a local table. Run read-only SQL, inspect values and rows, export results, and reopen saved imports.
Free: Opens files through exactly 100,000,000 bytes, includes two saved sessions, and supports row, page copy, and page export.
Pro: Uses the existing larger format limits and adds unlimited saved sessions and full-result export.
Turn pasted or opened logs into searchable events. Filter by severity or time, inspect raw records and context, and export diagnostic results.
Free: Opens files through 100 MiB, accepts paste through 20 MiB, includes two saved sessions, and keeps complete analysis, row/page copy, and page export.
Pro: Opens files through 500 MiB and adds unlimited sessions, Open in Local Data, full filtered-result export, and source-backed Raw Log export.
05 / EVERYDAY UTILITIES
Convert values, inspect schedules, and generate reusable output.
Convert Unix timestamps and common date strings, compare the same instant across timezones, and work with durations and boundaries.
Understand a five-field cron schedule, explore previous and next runs, and adjust supported schedules with a selected timezone.
Generate UUIDv4, UUIDv7, and ULID values in small batches, or inspect an existing ID and its available timestamp information.
Pick and convert colors, check WCAG contrast, and create palettes. Copy values for CSS, SwiftUI, AppKit, and other formats.
Inspect IPv4 addresses and CIDR networks, calculate subnet facts, and copy the values you need for network planning.
Familiar Mac controls. Local processing by default.
