Your AI writes Swift. We make sure it ships
The system in one pass
axint is the contract layer between agent-authored feature definitions and the Apple-native surfaces that have to ship. The compiler emits ordinary Swift. Cloud Check explains whether the output is safe to keep moving. Fix Packets turn failures into repair instructions. Registry makes reusable Apple capabilities installable.
01 · core engine
Compiler.
TypeScript, Python, and preview .axint definitions compile into App Intents, SwiftUI views, WidgetKit widgets, and app scaffolds.
02 · hosted validation
Cloud Check.
Hosted checks return a clear result before you go back to Xcode. Pro adds the Repair Loop — saved packet history, larger files, and agent handoff.
03 · repair contract
Fix Packets.
Compile, watch, and Swift validation runs write the same repair contract for CLI, MCP, and Xcode-facing workflows.
04 · ecosystem
Registry.
Public packages carry install commands, source visibility, compiler metadata, and compatibility details — not loose snippets.
What axint does
axint is an open-source compiler that transforms TypeScript, Python, or preview .axint definitions into native Swift. Use it when you want Apple-native features without brute-forcing App Intents, SwiftUI, or WidgetKit by hand.
01 · four apple outputs
App Intents, Views, Widgets, Apps.
App Intents for Siri / Shortcuts / Spotlight, SwiftUI views, WidgetKit widgets, and full app scaffolds — all from the same compiler pipeline.
02 · 34 mcp tools · 5 prompts
Built for MCP-speaking agents.
Claude Code, Codex, Cursor, Windsurf, VS Code, Xcode-facing workflows, and any MCP client can call compile, validate, scaffold, fix, and packet tools.
03 · 204 diagnostic codes
Apple-specific failure detection.
Diagnostics identify missing imports, plist copy, entitlements, Swift surface issues, and repair paths before the failure becomes a vague build problem.
04 · 1304 tests · 1190 TypeScript · 114 Python
Public proof, end-to-end.
Coverage spans parser, validator, generator, MCP, views, widgets, apps, templates, and fix flows. Use the proof page when you need receipts.
Reference surfaces
format
.axint.
The compact .axint format is the preview authoring surface for a small declarative feature shape. The format guide explains how .axint maps into IR, validation, and Swift.
benchmarks
Token-efficiency methodology.
Public benchmarks live on axint.ai/benchmarks. Methodology and current results.
examples
Working samples.
Package installs, generated Swift, Cloud results, and fix prompts live at registry.axint.ai/examples. Use it when you want concrete examples instead of a product tour.
status
Registry compatibility.
Compatibility status is public — bundle hash, validation, policy, and diff coverage.
thesis
Why this category exists.
The strategic argument lives at axint.ai/thesis. Use it when someone needs the reason agents need a compiler for Apple-native software.
Install
npm install -g @axint/compiler
# Or run without installingnpx -y -p @axint/compiler axint compile my-intent.ts --stdoutpip install axintclaude mcp add --transport stdio axint -- npx -y -p @axint/compiler axint-mcpcodex mcp add axint -- npx -y -p @axint/compiler axint-mcpYour first intent in 30 seconds

What it compiles
01 · defineIntent()
App Intents.
Swift AppIntent struct with parameters, perform(), and Siri / Shortcuts metadata.
02 · defineView()
SwiftUI Views.
SwiftUI View with props, state, and body — ready to embed in any app.
03 · defineWidget()
WidgetKit Widgets.
Complete widget with TimelineProvider, TimelineEntry, and view. ~13× compression over hand-written.
04 · defineApp()
App Scaffolds.
Full @main App struct with scenes, app storage, and settings pane.
26 bundled templates
Start from a working example instead of a blank file. Templates cover messaging, health, finance, commerce, smart home, media, navigation, and entity / query patterns.

axint ships with an MCP server that exposes 34 tools plus 5 built-in prompts. AI coding assistants compile, validate, and fix Swift without you writing a line of it.
The axint.schema.compile tool accepts ~20 tokens of JSON and returns compiled Swift — agents skip TypeScript entirely and save even more tokens.
{ "mcpServers": { "axint": { "command": "npx", "args": ["-y", "-p", "@axint/compiler", "axint-mcp"] } }}Works with Claude Code, Codex, Cursor, Windsurf, Zed, VS Code, JetBrains, Neovim, Xcode-facing workflows, and any MCP-compatible client.
Open source, no lock-in
Apache 2.0 licensed. No CLA. axint eject generates standalone Swift with zero axint dependency — you can walk away at any time and keep the generated code.

Move from docs to the real workflow
The docs should not end in passive reading. Pick the next step based on the job — compile locally, check hosted output, inspect the repair packet, or install a package.
