Track the evolution of DevUtilities through detailed release notes — new tools, improvements, and bug fixes across every version, in the order they shipped.
Startup performance
Saved Early Supporter and Lifetime Pro access, along with local trial status, are restored as soon as the app starts. App Store entitlement checks run independently in the background, so one slow request does not delay another result.
Product prices load when opening DevUtilities Pro without blocking tools, trial activation, or restore. Slow or unavailable verification preserves existing grants; verified refunds and revocations still update access.
AI providers
AI Chat and AI Translate now share one protocol-aware runtime. Choose OpenAI Compatible for GPT, DeepSeek, Qwen, Kimi, GLM, Gemini, and compatible gateways, or Anthropic Messages for Claude.
Anthropic providers use the native /messages schema and headers, top-level system prompts, image content blocks, and streamed text, thinking, and token-usage events. Claude no longer depends on an OpenAI-shaped proxy.
OpenAI Chat Completions and Responses are model-level endpoint choices inside the OpenAI-compatible family. This keeps provider setup simple while still supporting Responses-only models and OpenAI-native web and image tools.
Provider presets cover OpenAI, DeepSeek, Qwen, Kimi, GLM, Gemini, and Anthropic. The catalog now includes GPT-6.1 Sol (default), GPT-6 Sol/Luna/Astra, DeepSeek V4.1-Flash and V4-Pro, and Claude Fable 5.1 / Opus 5.5 / Sonnet 5.5. DeepSeek Flash now accepts images; Pro remains text-only.
Existing configurations upgrade automatically while retaining credentials, custom endpoints/models, enablement choices, and saved model identities. Providers default to OpenAI Compatible, and the old Responses toggle migrates to the new model endpoint field.
OpenAI read-aloud now uses gpt-realtime-2.1-mini over WebSocket with ten voices. New users start with marin; compatible existing selections are retained, and removed voices migrate to marin. Auto mode uses macOS speech if OpenAI playback cannot start. Stop closes the connection and clears queued playback. No microphone or saved chat context is sent.
Lifetime Pro
DevUtilities 3.0 moves from paid download to free download. Eighteen everyday tools stay free; AI Chat, AI Translate, Parquet, IP Lookup, Currency, JWT, and Crypto are included in Lifetime Pro.
The new access model includes a 30-day Pro trial that starts only when requested and 18 tools that remain free. After the trial, AI Chat, AI Translate, Parquet, IP Lookup, Currency, JWT, and Crypto require the one-time $19.99 Lifetime Pro purchase.
Users who first acquired DevUtilities from January 1, 2025 through October 24, 2026 automatically receive permanent Pro, whether the download was paid or free. Verified original acquisition history determines eligibility, not first launch. The DevUtilities Pro window brings trial status, purchase, and restore together; selecting a locked tool opens it without switching away from your current tool.
The website is now maintained alongside the app as a regular directory. Self-built copies may customize Pro access under the project license; choosing the official Mac App Store app and Lifetime Pro supports continued development.
Spotlight
DevUtilities now ships 11 Spotlight commands built on App Intents. Press ⌘Space, type what you need — convert a timestamp, generate a UUID, hash a string — fill the parameters inline, and read the result right in Spotlight. The app never has to open, and results are copied to your clipboard automatically.
Convert Timestamp (smart two-way, type now for the current time), Convert Number Base, Convert Unit (all 7 categories, e.g. 1024 MB → GB), Encode/Decode Base64, URL Encode/Decode, Decode JWT, Hash Text (MD5/CRC32/SHA-1/256/384/512), Generate UUID (v4/v7), and Generate Random String.
Every command is a native App Intent, so the same actions appear in the Shortcuts app for automation and can be invoked through Siri. On macOS 26 they surface as inline Spotlight actions with quick-key support.
Tool naming
Tool names are now concise and consistent across the app, website, and documentation. Recognizable technologies and formats use their canonical names — Base64, JWT, JSON, SQL, HTML, UUID, Crypto, URL, and Parquet — without repeating actions the tool already makes clear.
Ambiguous labels keep enough context: Unit Converter, Struct Converter, and Data Converter remain descriptive; HTTP Request is now HTTP Client, IP Query is now IP Lookup, and Base Converter is now Number Base.
The change is presentational. Stable tool identifiers and existing website URLs remain unchanged, so saved sidebar settings and bookmarked pages continue to work.
Data Converter
The 25th tool converts between JSON, YAML, TOML, and CSV in any direction. Pick a source and a target format with a from/to picker, or hit the swap button to flip them. Conversion runs instantly and entirely on-device.
A new shared value model stores objects as ordered key/value pairs and keeps date literals untouched, so conversions don't reshuffle your fields or reformat your timestamps. JSON is parsed with a custom order-preserving scanner, and YAML goes through the Yams library to preserve key order and quoting.
Nested objects and arrays flatten into dotted-key columns (address.city, tags.0) with an ordered union header across rows; reading CSV rebuilds the nesting. An Infer types toggle coerces cells like 123 and true into numbers and booleans, or keeps every cell as a string.
The Struct Converter now parses through the same value model — its output is unchanged.
Struct Converter
The 24th tool turns sample data into a ready-to-paste type definition. Drop in JSON, TOML, YAML, or a SQL CREATE TABLE block, and pick an output language — TypeScript, Python, Go, Java, Rust, Swift, or PHP. The tool walks every nested object, infers strings, numbers, booleans, ISO 8601 dates, arrays, and nullable fields, and emits idiomatic field names with serde renames, Swift CodingKeys, or Go struct tags preserving the original keys.
JSON parses via Foundation; TOML supports tables, dotted keys, and arrays of tables; YAML handles block-style mappings and sequences; SQL DDL parses multi-statement CREATE TABLE blocks and maps SQL column types (INT/VARCHAR/DECIMAL/TIMESTAMP/...) to language-native types, respecting NOT NULL.
TypeScript interface, Python @dataclass, Go struct with JSON tags and aligned columns, Java POJO with getters/setters, Rust struct with #[derive(Serialize, Deserialize)], Swift Codable struct with CodingKeys, and PHP class with typed properties. Closes issue #17.
AI Chat enhancements
Migrated to the Textual rendering engine for richer, more accurate Markdown output. Code blocks now have syntax highlighting across all languages, tables and nested lists render correctly, and streaming updates are smooth with no layout flicker.
Every code block in AI Chat responses now shows a Copy button. Grab any code snippet instantly without selecting text — perfect for copying commands, code examples, and configuration directly from the chat.
Added support for the OpenAI Responses API, enabling compatibility with GPT-5-pro and future models. Includes full SSE streaming and reasoning/thinking output — see the model's chain of thought as it streams. Enable per-model via the Use Responses API toggle in model settings.
AI Translate — OpenAI TTS
AI Translate now supports OpenAI's TTS engine alongside native macOS voices. PCM audio streams directly to the speaker — playback starts in realtime with no sentence splitting or waiting. Choose from 13 voices including alloy, nova, shimmer, echo, fable, and more. Configure mode (Auto / OpenAI / macOS) and voice in Settings → AI → Text-to-Speech.
Text Compare
A dedicated text comparison tool with visual diff highlighting. Compare any two text documents with real-time status updates, character and line metrics for both sides, and instant visual feedback showing additions, deletions, and modifications.
Diff mode for formatters
Currency
Real-time currency conversion across 38 major global fiat currencies — USD, EUR, GBP, JPY, CNY, KRW, INR, and 31 others. 24-hour smart caching keeps data fresh while minimising API calls; everything still works offline against the most recent cache.
A new tool for cryptographically secure random string generation with customizable character sets and advanced security requirements.
Native macOS text-to-speech is now integrated into AI Translate — listen to both source and translated text with one-click playback.
Enhanced Number Base with Base62 (0–9, A–Z, a–z) for URL shortening and compact identifiers. Five base systems — binary, octal, decimal, hexadecimal, and Base62 — convert simultaneously as you type, with custom toBase62 / fromBase62 implementations and character set validation.
A professional color format converter with real-time conversion between HEX, RGB, RGBA, HSL, HSLA, HSB, and CMYK formats. Edit any format directly — changes instantly reflect across all other formats.
