Snowflake Command Center

❄️ The ultimate Snowflake power tool — schema explorer, query console, cost tracker, warehouse monitor, Cortex AI, and more.

Snowflake Command Center — by SCube | The Power User Toolkit for Snowflake. Free. The only Chrome extension built specifically for Snowflake engineers, analysts, and admins. While the rest of the market offers nothing but a forgotten query formatter with zero ratings, Command Center is a full engineering workbench — schema explorer, SQL console, cost tracker, AI assistant, role inspector, task monitor, and more — all running directly against your Snowflake account with no backend, no subscription, and no data leaving your browser. Connect with OAuth 2.0 or a Personal Access Token. Your account identifier is detected automatically from your active tab. Multiple accounts? Switch between them instantly. SCHEMA EXPLORER Browse your entire object hierarchy — databases, schemas, tables, views, dynamic tables, Iceberg tables, sequences, stages, functions, procedures, streams, event tables, secrets, and tags — from a clean, searchable tree. Hover any table name on Snowsight to see row count, size, owner, and last modified without touching a worksheet. Copy a fully qualified DB.SCHEMA.TABLE name to clipboard with one click. QUICK CONSOLE A full SQL editor built into the extension. Syntax highlighting, async execution, result tables with sort and filter, multi-statement support, query cancellation, saved snippet library, and one-click export to CSV, JSON, or Excel. Run queries against any warehouse and role without opening a new worksheet. QUERY HISTORY BROWSER Every query you've run, searchable by date, warehouse, user, or status. See exact credit cost, bytes scanned, and bytes spilled per query. Rank your most expensive and slowest queries of the week or month. Re-run any historical query directly in the Quick Console. WAREHOUSE MONITOR Real-time warehouse status as a badge on the extension icon. Credit burn charts, warehouse load over time, one-click suspend and resume, and multi-warehouse comparison. Set credit-per-day alerts that fire before costs spiral. COST & BUDGET TRACKER Full cost dashboard: compute vs. storage vs. cloud services broken down by warehouse, database, schema, and table. Storage split into active, time-travel, and fail-safe tiers. Top 10 most expensive queries of the month. Cost attribution by user. Projected month-end spend based on current burn rate. Budget threshold notifications. ROLE & PERMISSION INSPECTOR See everything your current user can access in one view. Visualize the full role inheritance hierarchy. Reverse-lookup any user or role to see their entire grant matrix. Pick any table and see exactly which roles have SELECT, INSERT, UPDATE, DELETE. Paste a failing query and get an automatic missing-grants analysis. Export the full permission matrix to CSV for security audits. TASK & PIPELINE MONITOR Every scheduled task at a glance — succeeded, failed, running, or scheduled. Full execution history per task with duration trend. DAG visualization of predecessor/successor chains. Manual trigger, suspend, and resume without opening Snowsight. Browser notifications the moment any task fails. DATA QUALITY MONITOR Track row counts over time, alert on unexpected drops or spikes. NULL rate per column. Duplicate detection on key columns. Freshness monitor for critical tables. Schema drift detector that flags new, removed, or changed columns against a previous baseline. Define custom SQL assertion rules on a schedule. DATA LINEAGE VIEWER Visual upstream/downstream lineage for any table or view using Snowflake's native GET_LINEAGE(). Hot-tables heatmap of your most-accessed objects. Dead table detector — surfaces objects with zero reads in 30, 60, or 90 days. Export as image or JSON. SNOWSIGHT OVERLAY Injected directly into the Snowsight interface: column type badges on hover, table hover cards, query cost preview before you run, one-click query ID copy, and custom keyboard shortcuts. CORTEX AI — BUILT IN Natural Language → SQL: Describe what you need in plain English. Your live schema is sent as context. Get a ready-to-run query back. Cortex Analyst: Upload a semantic model YAML and ask business questions — returns SQL, explanations, and confidence scores. Query Explainer & Optimizer: Paste any complex SQL for a plain-English breakdown and AI-powered performance suggestions. Text Analysis: Run sentiment, classification, summarization, entity extraction, PII redaction, and translation against text columns in your results. Cortex Search: Query your Cortex Search Services directly — list, search, and test suggestions without writing code. Cortex Agent: Multi-step agentic interface combining Analyst, Search, and Inference in a single call. Vector Embeddings: Paste text, get a vector back — for testing similarity use cases before building them into pipelines. Model Browser: See exactly which LLMs are available in your account's region. ADMIN & PLATFORM TOOLS Grants Inspector: Full visual breakdown of who has what role, what privileges a role holds, and what future grants are set — using the native Grants REST API. Network & Password Policies: Account-level and schema-level policies reviewed without writing SHOW commands. Snowpark Container Services (SPCS): Manage compute pools, browse running services with live log tail and container health, navigate image repositories by tag and digest. Notebooks & Streamlit Apps: List, trigger, and manage versions without opening Snowsight. Integrations Browser: Read-only audit view of all API, catalog, and notification integrations. Data Sharing: Inbound/outbound shares, Snowflake Marketplace listings, and consumer account lists in one place. Session Manager: Quick-switch role and warehouse from a popup dropdown. Save multi-account connection profiles. REPORTING THAT ACTUALLY WORKS Every view exports. Query results, cost breakdowns, permission matrices, data quality reports, query history — all available as CSV or JSON with one click. No copy-pasting from Snowsight tables, no manual export queries. COMPLETELY FREE. NO BACKEND. NO TELEMETRY. Command Center makes direct API calls from your browser to your Snowflake account. There is no proxy server, no analytics backend, no subscription tier. Your credentials and query results never touch any third-party infrastructure — ever. For data engineers, analysts, and admins who want Snowflake to feel like a tool they actually control.
