A desktop GUI for Elasticsearch on macOS, Windows, and Linux. Free, open source, and built for engineers who'd rather not memorize the bulk API. Or skip the buttons and ask the built-in AI assistant.
Cluster monitoring, indices, search, query profiling, an API playground, and an AI assistant that can use them for you — all in one desktop app. No browser tab to lose, no curl to remember.
Ask in plain words. The assistant looks up indices, mappings, and cluster health, runs searches, and hands queries over to Search or the Playground. Anything that changes data waits for your approval. Bring your own key for OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible endpoint.
Live health, node and shard layout, throughput, latency — laid out in one place. Spot trouble before it pages you.
Keep several searches open in tabs, each with its own query and results, and find them again after a restart. Compose filters and aggregations, inspect results, then explain or profile any query to find what's slow.
Edit mappings, browse and update documents, tweak settings — all without composing a single PUT. Copy an index name or open it in Search straight from the list.
A built-in playground for ad-hoc API calls. Method, path, body, headers — fire it, read the response, move on. Your draft stays put while you move around the app, and templates keep the requests you reuse.
Save as many connections as you need, give each one a color so production never passes for staging, and reach private clusters through an SSH tunnel. The plug in the header turns red the moment a cluster stops answering.
Built dark-first. Light mode if you must.
Open as many clusters side-by-side as you need. Each window is its own session, and the Window menu jumps between them — no juggling tabs, no losing context.
Short answers. If you have something that isn't here, open an issue.
Yes. Elastron is free and open source under the GNU General Public License, version 3 or later. There is no paid tier, no feature gate, no “PRO” version waiting in the wings. The full source lives on GitHub.
No. Everything except the assistant works without one. To use the assistant, open Settings (the gear in the header), choose a provider — OpenAI, Anthropic, Google Gemini, or any OpenAI-compatible endpoint, such as a model you run yourself — and enter your own API key and model. Your provider bills that usage to your own account; Elastron adds nothing on top.
No. Reading — listing indices, checking mappings, running searches — happens on its own. Anything that writes, such as creating or deleting an index or changing documents, stops at an approval card that shows exactly what will run, and nothing happens until you approve it. Requests that can't be undone are marked as such.
Elastron talks to your cluster directly from your machine; there is no Elastron server in between. The app 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. It never reports hosts, credentials, queries, or documents.
The AI assistant is the one exception. When you use it, your messages and the cluster data it looks up are sent to the AI provider you configured, straight from your machine and with your own key. Results are capped before they are sent, and nothing goes to any provider until you set one up. See the privacy policy for details.
Elasticsearch 8.x and 9.x. Older versions may work but with limited functionality.
For macOS, Windows, and Linux. Free, forever.
