https://www.perryts.com/en/blog/ Dated Perry release notes, tutorials, and technical articles. Historical measurements remain tied to their original versions. en https://www.perryts.com/en/blog/compiling-javascript-aot/ https://www.perryts.com/en/blog/compiling-javascript-aot/ Fri, 30 Oct 2026 00:00:00 GMT An ahead-of-time compiler has to know, before the program runs, whether item.price is one load or a full lookup. How Perry proves whole-program facts about your JavaScript, the design that hit a wall, the per-unit design that replaced it, what failed, and where it stands. https://www.perryts.com/en/blog/gc-decisions-surprises/ https://www.perryts.com/en/blog/gc-decisions-surprises/ Wed, 12 Aug 2026 00:00:00 GMT Perry compiles TypeScript to native code with LLVM — which means it needs a real garbage collector. The decisions we made, the bugs that left no evidence, the CI gates that couldn't fail, and where the numbers stand against Node and a refcounting AOT competitor. https://www.perryts.com/en/blog/compiling-claude-code/ https://www.perryts.com/en/blog/compiling-claude-code/ Sat, 25 Jul 2026 00:00:00 GMT We pointed Perry at the 13 MB minified cli.js that npm ships for Claude Code and tried to turn it into a native binary. A month later it launches, logs in, streams a real API response, and paints what you type — and 160 pull requests had landed in Perry, from a no-op MessageChannel to a missing GC write barrier on RegExp headers. https://www.perryts.com/en/blog/shipping-a-watch-only-app-to-the-app-store/ https://www.perryts.com/en/blog/shipping-a-watch-only-app-to-the-app-store/ Tue, 07 Jul 2026 00:00:00 GMT Every documented way to upload a standalone watchOS app to the App Store fails — altool, iTMSTransporter, xcodebuild, even Xcode 26's Organizer all refuse the watchOS platform. Here's the undocumented workaround that works and keeps arm64_32 for older watches: an ITSWatchOnlyContainer iOS stub, uploaded with iTMSTransporter. https://www.perryts.com/en/blog/real-npm-packages-and-a-conformance-sweep/ https://www.perryts.com/en/blog/real-npm-packages-and-a-conformance-sweep/ Tue, 09 Jun 2026 00:00:00 GMT The ~270 releases from v0.5.875 to v0.5.1146 weren't about one benchmark — they were about making real npm packages compile and run. axios, zod v4, express, fastify, and hono now work; test262 parity jumped (String 60→79%, Array 61→72%); Windows went Fluent with Mica; and DatePicker + drag & drop landed on every platform. https://www.perryts.com/en/blog/closing-the-gc-gap/ https://www.perryts.com/en/blog/closing-the-gc-gap/ Tue, 12 May 2026 00:00:00 GMT A reader benchmarked Perry on AtCoder ABC451D and measured it 3.85× slower than Bun. A silent regression had widened the gap to 6.59× since. The fix wasn't where we expected, the deliberate GC trade-off it exposed was real, and Perry v0.5.875 now ties Bun on the same bench: 425 ms vs 431 ms. https://www.perryts.com/en/blog/updater-live-inspector-and-compiler-refactor/ https://www.perryts.com/en/blog/updater-live-inspector-and-compiler-refactor/ Tue, 28 Apr 2026 00:00:00 GMT Perry v0.5.306 → v0.5.359 in four days — 53 patch releases, ~30 issues closed, and three big things landed: perry/updater for desktop auto-update, a live inspector at localhost:7676, and a compiler refactor that shrank the four biggest files by 33–91%. https://www.perryts.com/en/blog/gen-gc-lazy-json-and-defensible-benchmarks/ https://www.perryts.com/en/blog/gen-gc-lazy-json-and-defensible-benchmarks/ Sun, 26 Apr 2026 00:00:00 GMT Perry v0.5.174 → v0.5.306 in three days, plus the GC and JSON work that landed alongside. The generational GC ships as default. The Small String Optimization ships as default. The JSON pipeline gets a lazy tape that lands at 75 ms median on validate-and-roundtrip — best in the dynamic-typing pack. The benchmarks page is rewritten with RUNS=11 median + p95 + σ, simdjson and AssemblyScript+json-as added as peers, and every weakness Perry has surfaced honestly. https://www.perryts.com/en/blog/npm-perry-dev-and-beating-bun/ https://www.perryts.com/en/blog/npm-perry-dev-and-beating-bun/ Thu, 23 Apr 2026 00:00:00 GMT Perry v0.5.80 → v0.5.174 in six days. @perryts/perry ships on npm for all seven supported platforms. perry dev adds watch-mode auto-recompile on top of an in-memory AST cache and on-disk per-module object cache. json_roundtrip closes its last gap — Perry now wins every benchmark against both Node.js and Bun. https://www.perryts.com/en/blog/optimizing-everything/ https://www.perryts.com/en/blog/optimizing-everything/ Fri, 17 Apr 2026 00:00:00 GMT Perry v0.5.13 → v0.5.80 in seven days. JSON.parse closes a 547x gap to Node. mimalloc lands as the global allocator. Inline caches, shape transitions, typed buffer slots, i32-native bitwise ops, scalar replacement, and a native event loop that keeps Fastify and WebSocket servers alive. https://www.perryts.com/en/blog/cranelift-to-llvm/ https://www.perryts.com/en/blog/cranelift-to-llvm/ Sun, 12 Apr 2026 00:00:00 GMT Perry's backend migration from Cranelift to LLVM is finished. The initial cutover made benchmarks 70x slower — this is what broke, and the six targeted optimizations that fixed it. https://www.perryts.com/en/blog/tvos-cross-compile-and-perry-login/ https://www.perryts.com/en/blog/tvos-cross-compile-and-perry-login/ Sat, 28 Mar 2026 00:00:00 GMT Perry v0.4.24: tvOS as the 10th compilation target, cross-compile iOS and macOS from Linux via ld64.lld, perry login with usage-based billing, Windows UI overhaul, macOS notarization, and 120 commits in 5 days. https://www.perryts.com/en/blog/true-multithreading-i18n-and-watchos/ https://www.perryts.com/en/blog/true-multithreading-i18n-and-watchos/ Mon, 23 Mar 2026 00:00:00 GMT Perry v0.4.0: real OS threads with compile-time safety, a zero-ceremony internationalization system for 30+ locales, watchOS as the 9th compilation target, audio and camera APIs, and a parallel compiler pipeline. https://www.perryts.com/en/blog/cross-compile-windows-game-loops-and-parity/ https://www.perryts.com/en/blog/cross-compile-windows-game-loops-and-parity/ Fri, 20 Mar 2026 00:00:00 GMT 103 commits in one week: cross-compile to Windows from Linux via lld-link, iOS game loop support, crash reporting, a two-stage Hub build pipeline, and the self-hosting compiler hits 68/68 deterministic test parity. https://www.perryts.com/en/blog/the-full-pipeline/ https://www.perryts.com/en/blog/the-full-pipeline/ Fri, 13 Mar 2026 00:00:00 GMT 82 commits in one week: a 49-page documentation site, automated App Store and Play Store publishing, Homebrew and APT packages, native WidgetKit extensions from TypeScript, new widgets, http/https modules, and a self-hosting LLVM compiler. https://www.perryts.com/en/blog/from-compiler-to-ecosystem/ https://www.perryts.com/en/blog/from-compiler-to-ecosystem/ Fri, 06 Mar 2026 00:00:00 GMT Perry grows from a compiler into a full ecosystem. perry/ui at the core, Prisma-compatible ORMs for MySQL/PostgreSQL/SQLite, universal push notifications, distributed builds with App Store publishing, and a React compatibility layer — all in one week. https://www.perryts.com/en/blog/all-six-platforms-ui-parity/ https://www.perryts.com/en/blog/all-six-platforms-ui-parity/ Sat, 28 Feb 2026 00:00:00 GMT 20+ native UI widgets, a Canvas widget, Table views, system notifications, keychain access, multi-window support, and full feature parity across macOS, iOS, iPadOS, Android, Linux, and Windows — all from a single TypeScript codebase. https://www.perryts.com/en/blog/plugin-systems-are-a-performance-tax/ https://www.perryts.com/en/blog/plugin-systems-are-a-performance-tax/ Fri, 27 Feb 2026 00:00:00 GMT Plugin architectures trade performance for extensibility. But what if extensibility happened at build time instead of runtime? Compile-time composition gives you both — zero overhead, full flexibility. https://www.perryts.com/en/blog/compiling-hono-trpc-strapi/ https://www.perryts.com/en/blog/compiling-hono-trpc-strapi/ Wed, 25 Feb 2026 00:00:00 GMT Perry now compiles three major TypeScript frameworks — Hono, tRPC, and Strapi — into native ARM64 executables. They compile in under a second, produce binaries under 2 MB, and run without crashes. https://www.perryts.com/en/blog/building-pry/ https://www.perryts.com/en/blog/building-pry/ Thu, 20 Feb 2025 00:00:00 GMT A walkthrough of building Pry, a native JSON viewer compiled from TypeScript to machine code with the Perry runtime and GC linked in and no webview. https://www.perryts.com/en/blog/cross-platform-native-ui/ https://www.perryts.com/en/blog/cross-platform-native-ui/ Sat, 01 Feb 2025 00:00:00 GMT How Perry maps one TypeScript codebase to platform widgets across its documented targets, including the platform-specific limitations and prerequisites. https://www.perryts.com/en/blog/introducing-perry/ https://www.perryts.com/en/blog/introducing-perry/ Wed, 15 Jan 2025 00:00:00 GMT Perry compiles supported TypeScript to standalone native executables with its runtime and GC linked in, without requiring an external Node.js installation or JavaScript engine.
