Cerebro Lite – ES cluster admin

Elasticsearch admin in your browser: shards, nodes, documents, REST console, snapshots, templates, ILM and cluster settings.

Cerebro Lite is an Elasticsearch admin tool that lives in your browser. Shards and nodes, index management, documents, a REST console, snapshots, templates and lifecycle policies, cluster settings and tasks: seven tabs, light and dark, with a command palette to get anywhere fast. The extension talks to your clusters directly, so there is no server to deploy. That makes it handy for clusters you can only reach from your own machine, such as clusters behind a VPN. Features • Shards: one row per index and one column per node, with unassigned, initializing and relocating shards and recovery progress; filter, sort, move shards, drain nodes, toggle allocation • Index management: create indices, edit settings (with a diff before saving), aliases, analyze text, ILM status, rollover, clone, reindex, open, close, force merge and delete, for one index or all filtered ones • Nodes: heap, disk with watermarks, CPU, load, uptime, indexing and search rates and thread pool rejections; a details drawer with memory, disks, thread pools, circuit breakers, plugins and hot threads • Documents: search with query strings or the query DSL and time ranges, sort, page past 10,000 hits, pick columns, view, edit, create and delete documents, delete by query, export a page • Console: Kibana-style requests with autocomplete, formatting, history, examples and copy as cURL • Snapshots: repositories, snapshots with progress, create, delete and restore with rename preview, SLM policies • Data: index, component and legacy templates with simulate, data streams, ILM policies with a phase editor, ingest pipelines with simulate • Cluster: health report with affected resources, cluster settings with defaults, tasks with progress and cancel, pending tasks • Command palette (Cmd/Ctrl+K) for pages, indices, nodes, policies and actions; g-then-letter shortcuts to switch tabs • Recent changes: health, nodes, the elected master, indices and unassigned shards since you connected • Saved clusters with color tags and an optional read-only mode; Basic, API key and bearer token authentication • English and Simplified Chinese; light and dark themes that follow your system Works with Elasticsearch 7.10+, 8.x and 9.x. Privacy: requests go straight from your browser to the clusters you add. The extension has no server, collects no data, and asks for access to a cluster's host only when you connect to it.
