A desktop client for Elasticsearch 8 and 9, for macOS, Windows, and Linux. Manage indices, documents, and mappings, run and profile queries, watch cluster health — or just ask the built-in AI assistant to do it. Free and open source.

The project is maintained by AI.
- AI assistant — ask about the cluster in plain words. It looks things up, runs searches, and hands queries to Search or the Playground. Changes wait for your approval.
- View and manage indices, documents, and mappings
- Search in tabs, each with its own query, filters, aggregations, and results
- Explanation and profiling of search queries
- Monitoring of cluster health and performance
- API Playground, with a draft that survives restarts and templates for requests you reuse
- Saved connections, color-coded, over a direct link or an SSH tunnel
- Multi-window support — one window per cluster
- Elasticsearch 8 and 9 support
- Dark mode support
- Automatic updates
Download the build for your platform from the latest release, or from elastron.eney.solutions. macOS builds are signed and notarized, so they open without a Gatekeeper detour. Elastron checks for updates on its own and can install them for you.
The assistant is off until you give it a provider. Open Settings (the gear in the header), choose the AI Integration section, and pick OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible endpoint — including a model you run yourself. Add your own API key and the model name.
Reading — listing indices, checking mappings, running searches — happens on its own. Anything that writes stops at an approval card showing the exact request, and runs only when you approve it. Requests that cannot be undone are marked.
Your key is stored encrypted on your machine and is sent only to that provider, which bills the usage to your own account. See the privacy policy for what leaves your machine.
Requires Node.js 22 and Yarn.

yarn dist #for allyarn dev starts the Vite dev server and Electron together. yarn start runs Electron against
an existing build/, so run yarn build first. Packaging and publishing read their credentials
from a local .env; analytics stay off unless PUBLIC_GA_ID is set there.
Elastron is an Electron app whose renderer talks to a local SvelteKit (adapter-node) server,
which owns the Elasticsearch client and acts as a backend-for-frontend. State lives in Storeon
modules under src/lib/store. AGENTS.md describes the layout in depth, and
CLAUDE.md covers conventions for working in this repo.
Behaviour is specified before it is built. openspec/specs holds the current specification of
each capability, and openspec/changes holds changes being worked on. When you change
behaviour, update the spec in the same pass.
Elastron talks to your cluster directly from your machine. It reports anonymous usage to Google Analytics — the app version, which screens are opened, the Elasticsearch version of clusters you connect to, and that an assistant message was sent or answered. The AI assistant sends your messages and its lookups to the provider you configured, and nothing else leaves your machine. The full privacy policy has the details.
