By the numbers

A quantitative snapshot of the tauri-apps/tauri repository.

Data collected on 2026-04-30 from the dev branch (HEAD 1ca61fd74759).

Size

Lines of source code by language (excluding .git, target, node_modules, lockfiles):

Language	Lines of code
Rust (.rs)	97,112
TypeScript (.ts)	8,335
Kotlin (.kt)	2,467
JavaScript (.js)	2,316
Swift (.swift)	945

The Rust monorepo dominates. Kotlin and Swift account for the Android plugin glue (crates/tauri/mobile/) and the iOS bridge respectively. The TypeScript total is split between packages/api (the public JS bindings) and crates/tauri-schema-worker (a Cloudflare Workers helper that serves config schemas).

File counts

• 323 .rs files across 14 Cargo crates.
• 28 .ts files in packages/api plus a handful in the schema worker.
• 40 .kt and 37 .swift files for the mobile plugin templates and runtime glue.

Largest files

File	Lines
crates/tauri-runtime-wry/src/lib.rs	5,383
crates/tauri-utils/src/config.rs	4,738
crates/tauri/src/webview/webview_window.rs	2,689
packages/api/src/window.ts	2,672
crates/tauri/src/app.rs	2,636
crates/tauri/src/webview/mod.rs	2,380
crates/tauri-bundler/src/bundle/settings.rs	1,319
crates/tauri/src/lib.rs	1,254
crates/tauri/src/manager/mod.rs	1,038
crates/tauri-cli/src/icon.rs	986

These five-figure files are not necessarily candidates for a split — webview_window.rs and window.ts are mostly thin builder/getter methods, and tauri-utils/src/config.rs is generated-flavor code that mirrors the JSON schema.

Lockfiles top the churn list (Renovate keeps them moving). The next tier — config.rs, config.schema.json, the schema generator — reflects ongoing config schema evolution. tauri-runtime-wry/src/lib.rs and webview_window.rs are the natural hotspots for window/webview behaviour.

Bot-attributed commits

Out of 5,956 total commits, 1,309 (~22%) were authored by bots — most via renovate[bot] (980), github-actions[bot] (238), and dependabot[bot] (91). Tauri leans heavily on Renovate for dependency churn. This is a lower bound on automation since inline tooling like Copilot leaves no signature in git history.

Complexity

• 14 Rust crates in the workspace plus 4 example/test crates and a Node.js Cargo wrapper (packages/cli).
• 2 published npm packages (@tauri-apps/api, @tauri-apps/cli).
• 12 example apps under examples/ covering the major features (multiwindow, isolation, splashscreen, drag, file-associations, resources, streaming, state, run-return, multiwebview).
• 50 TODO / FIXME / HACK comments across 37 Rust files — small for a project this size.

Test-to-code ratio (rough)

• Rust unit and integration tests sit alongside production code (#[cfg(test)] mod tests) plus dedicated suites under crates/tests/ (acl, app-updater, restart).
• The crates/tauri/test/ directory holds fixture projects exercised by cargo test -p tauri --all-features.
• JS unit tests use vitest (configured per package) and are run by pnpm test.
