HuLa: a Tauri and Vue 3 instant messaging client for five platforms

What HuLa is, and the gap it fills

HuLa is a client, not a hosted service. The README describes it as an instant messaging system built on Tauri, Vite 7, Vue 3 and TypeScript, and the repository is the desktop and mobile application; the server lives in a separate repository, HuLa-Server, linked from the README with GitHub and Gitee mirrors. That split is the first thing to understand. Cloning HuLa gives you the interface, the Rust side that Tauri compiles, and the packaging scripts. It does not give you accounts, message routing or storage.

The intended audience is developers who want a chat client they can build themselves and point at their own backend. The README points to a project guide at docs/project_guide.md for environment setup and startup, and the package.json declares Node ^20.19.0 or >=22.12.0 and pnpm >=10. Those version floors are enforced: the preinstall script runs pnpm dlx only-allow pnpm, so an npm or yarn install is rejected before dependencies resolve.

The package metadata puts the version at 3.0.9, matching the most recent release listed for the repository, v3.0.9 on 2026-01-19. The last push to the default branch was on 2026-09-11, so the codebase has moved since that tagged release.

Tauri as the shell, Vue 3 as the interface

The architecture follows a pattern that is now common for small cross-platform clients. Vue 3 renders the interface inside a webview, and Tauri supplies the native window, the platform integrations and the Rust layer that is compiled per target. Vite 7 handles the front-end dev server and the production bundle, and TypeScript runs through vue-tsc during the build script. UnoCSS and Sass handle styling, according to the technology badges in the README.

The consequence of that layout is that the same Vue code is reused across five targets. The scripts in package.json show how the mobile paths are launched: tauri android dev and tauri ios dev for real device or emulator runs, plus adev:win and idev:mac for driving only the front end on Android and iOS without the native shell. That second pair is useful when you are changing layout and do not want a full native rebuild.

There is also a tauri-plugin-hula/ directory at the repository root, which indicates the project maintains its own Tauri plugin rather than relying only on upstream plugins. The README does not describe what that plugin does, so treat it as an area to read in source before you depend on it.

One design note worth stating plainly: a webview-based chat client inherits the memory behaviour of the webview, not of a native toolkit. The README claims exceptional performance in the repository description, but it publishes no measurement, and the documentation does not include a benchmark methodology. Treat the performance framing as a claim, not a number.

Installing HuLa and running it for the first time

The README sends readers to docs/project_guide.md for environment configuration and startup, and package.json fixes the toolchain. Install pnpm first, then let the preinstall guard check the environment. The scripts/check-all.js file runs as part of preinstall, so a failing check stops the install before node_modules is populated.

pnpm install

After dependencies resolve, the desktop app starts through the Tauri dev command. The package.json defines tauri:dev for this and a shorthand, td, that maps to the same tauri dev invocation.

pnpm tauri:dev

You should see Vite start the front-end dev server and Tauri open a native window once the Rust side finishes compiling. The first compile is the slow one; later runs reuse the Cargo cache under .cargo/ and src-tauri/.

For mobile, the same file exposes pnpm adev and pnpm idev, which call tauri android dev and tauri ios dev. If you only need to iterate on the Vue layer for a phone-sized viewport, pnpm adev:win on Windows or pnpm idev:mac on macOS runs Vite alone with TAURI_ENV_PLATFORM set.

pnpm adev:win

Packaging goes through an interactive script rather than a plain tauri build. Both tauri:build and the shorthand tb run node scripts/interactive-build-inquirer.js, which asks for the target before building.

pnpm tb

None of this produces a working messenger on its own. The client needs the HuLa-Server backend from the companion repository, and the README does not document the connection settings in the excerpt available here, so read docs/project_guide.md before assuming a default endpoint exists.

The web target is deliberately closed

The platform table in the README lists Windows 10 and 11, macOS 10.5+ with Mac26 supported, Ubuntu 22.0+, iOS 9.0+ and Android 12+ (SDK30+). Web is listed with a warning and the note that it is not supported, and that supporting it would require custom removal of desktop functionality.

That is an honest limitation rather than an oversight, and it should shape your evaluation. If your users expect to open a URL and chat, HuLa is the wrong tool. The client assumes native capabilities that a browser tab does not provide, and the project has chosen not to maintain a degraded web mode. Forking to add one means auditing every place the front end calls into the Tauri layer.

There is a second constraint in the same table. The iOS row notes that Tauri does not support running on Intel-chip iOS 26 simulators, so an Intel Mac is a poor development host for the iOS target. Android starts at SDK30, which excludes older devices that a browser-based client would still reach.

How HuLa compares with OpenIM-based clients

The related searches around this project include OpenIM flutter, which points at a genuinely different approach. OpenIM is a server and SDK stack with its own client SDKs, and Flutter clients built on it draw their UI from Dart widgets compiled to native code. HuLa draws its UI from Vue 3 running in a webview, with Tauri providing the shell.

The practical difference is where your effort goes. With an OpenIM Flutter client, the interface is Dart and the SDK is the vendor's; you inherit a messaging protocol and a set of client libraries. With HuLa, the interface is Vue and TypeScript, which is a much larger hiring pool for front-end work, and the backend is the project's own HuLa-Server rather than a third-party SDK. You also inherit Tauri's packaging story, which covers desktop and mobile from one configuration.

Neither is strictly better. A Flutter client avoids the webview and its memory profile; a Tauri client reuses web skills and ships a smaller native surface. If your team already writes Vue, the second is less friction. If you need a messaging SDK with published client libraries and do not want to run the backend yourself, the first is closer to what you want.

Maintenance, release cadence and licence

The release history shows v3.0.7 on 2025-12-19, v3.0.8 on 2025-12-31 and v3.0.9 on 2026-01-19, a burst of three releases in about a month, followed by no tagged release in the record up to the last push on 2026-09-11. The repository is not archived, and work continued on master after the last tag. If you depend on tagged artifacts, note that the gap between the newest tag and the newest commit is several months.

Upgrade cost is dominated by the Tauri and Rust toolchain rather than by the Vue code. When Tauri changes, src-tauri/ and the .cargo/ configuration both need attention, and the project's own tauri-plugin-hula/ has to stay compatible with the Tauri version in use. The preinstall guard also means a Node or pnpm upgrade that falls outside the declared ranges will block installs until package.json is updated. Budget for that before pinning CI to a newer Node.

The licence is Apache-2.0, declared in package.json and in the LICENSE file at the repository root. Apache-2.0 permits commercial use and modification and includes an explicit patent grant, with the usual requirements around preserving notices and stating changes. Redistribution obligations and trademark questions are fact-specific, so read the LICENSE text and take advice if you plan to ship a modified client under your own name.

Editorial conclusion

HuLa fits teams that want a Tauri-based chat client they can fork and pair with the HuLa-Server backend, and it fits developers studying how a Vue 3 front end is packaged for desktop and mobile from one codebase. It does not fit anyone who needs a browser-served messenger, since the README marks Web as unsupported and notes that desktop features would have to be removed by hand. Before committing, read docs/project_guide.md, confirm the pnpm and Node ranges in package.json, and check that the HuLa-Server side matches the client version you build.
