Arka vs Omni: Choosing the Right Modern BI Platform

A detailed comparison between Arka's natural language approach and Omni's semantic layer-first BI platform.

Both Arka and Omni aim to modernize business intelligence, but they take fundamentally different approaches. Understanding these differences will help you choose the right platform for your organization's needs.

What is Omni?

Omni is a modern BI platform built around the concept of a centralized semantic layer. It requires defining your data models, metrics, and relationships upfront in code (using LookML-style modeling). Once set up, users can create dashboards and reports using drag-and-drop interfaces or limited natural language capabilities.

What is Arka?

Arka is a self-serve analytics platform that eliminates the need for semantic layers. It uses AI to understand your data schema directly, allowing business users to get insights through natural language queries immediately—no modeling required.

Key Differences

Semantic Layer Requirement

Omni: Requires building and maintaining a semantic layer. Data teams must define metrics, dimensions, and relationships in code before business users can access data. This adds weeks of setup time and ongoing maintenance.

Arka: No semantic layer needed. Arka's AI understands your database schema automatically. Start querying your data in minutes, not weeks.

Natural Language Capabilities

Omni: Offers basic natural language features as an add-on to their primary drag-and-drop interface. Still requires users to understand the underlying data model.

Arka: Natural language is the primary interface. Ask complex questions like "Show me customers with declining usage who haven't contacted support" without knowing table names or relationships.

Setup & Time to Value

Omni: Requires weeks to model your data, define metrics, and set up governance. Business users can't self-serve until this foundation is built.

Arka: Connect your data sources and start getting insights in minutes. No upfront modeling required.

Maintenance Burden

Omni: Every schema change requires updating the semantic layer. Adding new data sources means more modeling work for data teams.

Arka: Adapts automatically to schema changes. New data sources become queryable immediately without additional configuration.

AI-Native Dashboards

Omni: Traditional dashboards with filters and dropdowns. Users must know what questions to ask upfront through pre-built visualizations.

Arka: Conversational dashboards that respond to natural language. Explore data dynamically without clicking through endless filter combinations.

Learning & Adaptation

Omni: Static semantic layer. Changes require manual updates by data teams.

Arka: Organization memory that learns from every interaction. Captures corrections and business context automatically.

Workflow Automation

Omni: Scheduled reports and alerts, but setting them up requires understanding the semantic layer structure.

Arka: Create workflows through natural language. "Alert me when ARR growth drops below 20%" sets up monitoring without configuration.

The Semantic Layer Debate

Omni's approach assumes that centralizing metrics definitions in a semantic layer is necessary for governance. While this sounds good in theory, it creates several problems:

  • Bottlenecks: Data teams become gatekeepers for any new metric or analysis
  • Slow iteration: Testing new hypotheses requires code changes and deployments
  • Rigidity: The semantic layer can't anticipate every business question
  • Maintenance overhead: Every schema change breaks things until the semantic layer is updated

Arka proves that you don't need a semantic layer to maintain governance. AI can understand your data model directly while still enforcing permissions, ensuring accuracy, and maintaining consistency.

Real-World Comparison

Scenario: New Product Launch Analysis

Your company just launched a new feature and the Product team needs to understand adoption.

With Omni: First, data team updates the semantic layer with new feature metrics (1-2 days). Then Product team creates dashboards using the new metrics (few hours). Total time: 2-3 days before getting insights.

With Arka: Product team immediately asks "Show me adoption of the new feature by customer segment." Gets answer in seconds. No waiting for data team.

When to Choose Omni

  • You have a large data team that can build and maintain semantic layers
  • Your metrics are extremely stable and rarely change
  • You prefer drag-and-drop dashboard building over natural language
  • You're willing to invest weeks in upfront modeling
  • Your organization prefers centralized metric definitions over flexibility

When to Choose Arka

  • You want business users to self-serve without data team bottlenecks
  • You need to get started in minutes, not weeks
  • Your business questions evolve quickly (startups, fast-growing companies)
  • You have limited data team resources
  • You want AI that learns and adapts to your organization
  • You prefer conversational analytics over drag-and-drop interfaces
  • You value flexibility over centralized metric control

The Verdict

Omni is a solid modern BI tool if you're willing to invest in semantic layer development and maintenance. It's an improvement over legacy BI tools but still requires significant data team involvement.

Arka represents a fundamentally different approach: true self-serve analytics where AI understands your data directly, eliminating setup time and ongoing maintenance while democratizing data access across your organization.
