Whoisdigger is a cross-platform bulk WHOIS lookup desktop app built on Tauri v2 with a Rust backend. Now written in TypeScript and Rust.
Whoisdigger is a bulk whois lookup, cross-platform, desktop application. Made with builders and creators in mind, rapidly lookup up your favorite domain mashups without risking third-party logging, domain squatting and a few other common issues that come with using third-party platforms. The faster, reliable and most private way of looking for domains.
- Fast WHOIS lookup using native Rust
whois-rust - Better search privacy
- Raw text WHOIS replies
- Bulk WHOIS lookup with multi-threaded performance
- Bulk DNS sweep lookup
- Optional request caching with SQLite backend (
rusqlite) - Proxy support for outgoing requests
- Wordlist capabilities with drag n' drop
- IDNA 2003/2008 (UTS46), Punycode, non-ASCII character filter support
- Public Suffix List (PSL) and wildcard filtering
- Basic bulk WHOIS result analyser (csv import)
- Persistent settings through JSON file with live updates
- Redesigned settings interface with auto-save
- Dark mode toggle
- Follow system theme option
- Domain monitor (Rust implementation)
- Misc tools
- Settings
- Help page
- Experimental AI domain availability checks
Q: Can i search for emojis?
A: Yes, whoisdigger has IDNA and Punycode support
Q: Can i do a million word list lookup?
A: Yes, but be aware that big wordlists come with a humongous time penalty using purely whois (that to avoid unintentional DDOSing or blocking), use DNS sweep with care for large lookups if you only need availability.
Q: How long will it take doing a million word list DNS sweep?
A: Close to 14 hours on a 50ms delay, i wouldn't ever recommend doing such a thing. Be responsible.
Q: How does DNS sweep work?
A: DNS sweep as it says, sweeps through NS records of every domain on the wordlist, availability is based off of NS record presence for that domain.
Q: How much faster is DNS sweep?
A: It will largely depend on the set time between requests but on average is between 10x to 100x faster.
Stay on the bleeding edge of whoisdigger commits using git clone or for slightly tested version download the latest built release.
Check out and download the latest release for your architecture/OS.
Basic whoisdigger requirements are Node.js v20 or later, Rust, npm and git.
Clone whoisdigger code and install dependencies
git clone https://github.com/supermarx/whoisdigger
cd whoisdigger
npm install
After clone, run using
npm start
which will launch the application in development mode using Tauri.
Whoisdigger uses a build step before packaging.
npm run build:appThis will compile the TypeScript frontend and build the Rust backend into a production bundle.
Translation files live under app/locales/ and are simple JSON maps of keys to translated strings.
Add a new <lang>.json file (e.g. fr.json) with your translations. When ui.language is
omitted, the application falls back to navigator.language (first segment before -) to select the
locale file. To force a specific language, set ui.language inside appsettings.ts. Templates
reference strings using the {{t}} helper.
Run nvm use to switch to the Node version defined in .nvmrc.
Run npm install or npm ci before testing or linting to ensure all dependencies are installed.
After installing, execute npm test to run the project's unit tests.
Run npm run test:e2e to execute end-to-end tests that ensure the application starts cleanly.
Running tests also generates a coverage report in the coverage/ directory.
Development packages such as @types/node and @types/jest are required for TypeScript compilation and running tests. The prebuild script will auto-install dependencies if node_modules is missing.
Use npm run dev to watch source files and automatically reload the application during development. Static assets such as stylesheets are synced to dist while this command runs, so CSS changes are picked up without rebuilding.
Run npm run format before committing to apply Prettier formatting. CI will verify formatting with npm run format:check.
Modules within Whoisdigger may execute in both CommonJS and ESM contexts. Use
dirnameCompat() from app/ts/utils/dirnameCompat.ts to obtain a directory
name that works in either environment. Pass import.meta.url when calling from
an ES module:
import { dirnameCompat } from './utils/dirnameCompat';
const __dirname = dirnameCompat(import.meta.url);The helper checks for a globally defined __dirname, falls back to the provided
import.meta.url (or the current module's __dirname in CommonJS), then tries
__filename, process.mainModule?.filename or process.argv[1] before
falling back to process.cwd().
Whoisdigger uses a settings file that rules how the application behaves overall, this can be achieved by either using the preload settings file or change the appsettings.ts inside js.
Context isolation is always enabled for security purposes and cannot be disabled in configuration. Node integration is enabled by default, allowing renderer scripts to access Node.js directly. You can disable it through the configuration if required.
The settings screen provides a Follow system theme toggle. When enabled the application automatically switches between dark and light modes according to your operating system preference. This behaviour is controlled by the theme.followSystem setting which can be set to true or false in the configuration file.
Enable Confirm before exiting to receive a prompt before Whoisdigger closes. Toggle this option in the interface or set ui.confirmExit in the configuration file.
You can use assumptions (lookup.assumptions settings section) to make more reliable searches in cases where you're getting inconsistencies across different tests.
uniregistry, Assume a domain is unavailable when uniregistry query limit is reached, default: true.
Note: Uniregistry whois has a very low threshold on whois requests, a few requests with relative small timings in between will result in a sure temporary block, by assuming a rate limiting reply from uniregistry as a taken domain, you ensure that you're not getting a false/undetermined reply error.
ratelimit, Assume a domain is unavailable when getting rate limit reply, default: false
unparsable, Assume a domain as available if reply is unparsable, it may help correcting malformed, unusual or unhandled whois replies, default: false
dnsFailureUnavailable, Assume a domain is unavailable in a DNS sweep if request fails, this avoids having false positives on availability, default: true
Whoisdigger can optionally use a local ONNX model or OpenAI to predict domain availability.
Configure these features in the ai section of appsettings.ts:
ai.enabled- toggle AI featuresai.modelPathandai.dataPath- local model and data locationsai.modelURL- remote URL to download the modelai.openai.urlandai.openai.apiKey- OpenAI endpoint and API key
Train a local model from a labelled dataset via the CLI:
node dist/app/cli.js --train-model path/to/dataset.json
The dataset format is documented in docs/ai.md.
Whoisdigger uses a small build step before packaging. Each packaging command
compiles the application into the dist folder and then invokes
@electron/packager.
Running npm run build automatically executes the prebuild script. scripts/prebuild.js installs dependencies using npm install if node_modules is missing.
If you need a fresh build, run npm run clean first to remove the dist, release_builds and app/compiled-templates directories.
scripts/postbuild.js then bundles CSS using PostCSS by calling npm run build:css,
which minifies files from app/css into dist/app/css.
It also precompiles Handlebars templates and writes dist/app/html/mainPanel.html
from app/html/templates/mainPanel.hbs.
The prebuild step automatically regenerates vendor scripts under app/vendor. Run
npm run regen:vendor if you need to refresh them without a full build.
MacOS
npm run package-mac
Windows
npm run package-win
Linux
npm run package-linux
For convenience a single command builds packages for all platforms:
npm run package-all
Translation files live under app/locales/ and are simple JSON maps of keys to translated strings.
Add a new <lang>.json file (e.g. fr.json) with your translations. When ui.language is
omitted, the application falls back to navigator.language (first segment before -) to select the
locale file. To force a specific language, set ui.language inside appsettings.ts. Templates
reference strings using the {{t}} helper.
Build the Docker image:
docker build -t whoisdigger -f docker/Dockerfile .Run the application (requires X11 forwarding to display Electron). Ensure an X server is active on the host and allow local connections:
xhost +local:
docker run --rm -it \
-e DISPLAY=$DISPLAY \
-v /tmp/.X11-unix:/tmp/.X11-unix \

docker compose -f docker/docker-compose.yml upExecute the test suite inside a container:
docker run --rm -it whoisdigger npm testDistributed under the MIT License. See license.md for more information.
