Castor pricing guide details
Pricing Overview
Castor, now operating as Coalesce Catalog, follows an enterprise pricing model that requires prospective buyers to request a custom quote directly from the vendor. There are no publicly listed plan tiers or self-serve sign-up options. This approach is standard among enterprise data catalog and governance platforms targeting mid-size to large organizations with complex data stacks.
The platform delivers AI-powered data discovery, automated documentation, column-level data lineage, natural language search, and natural language to SQL conversion. Castor also provides data governance capabilities including sensitive data classification, role-based access control, and audit trails. All pricing is scoped to the specific deployment, making direct cost comparison difficult without engaging the sales team.
Organizations evaluating Castor should prepare to discuss their data volume, number of integrations, and user count, as these factors shape the final quote.
Plan Comparison
Castor does not publish discrete plan tiers. Instead, the vendor tailors each contract to the buyer's requirements. Based on available information, the key variables that influence pricing include:
| Pricing Factor | Details |
|---|---|
| Pricing Model | Enterprise (custom quote) |
| Public Free Tier | None |
| Free Trial | Not publicly offered |
| User Licensing | Scoped per contract |
| Integrations | Connects to Snowflake, BigQuery, Redshift, dbt, Airflow, Fivetran, Looker, Tableau, and others |
| Deployment | Cloud-hosted |
| Core Modules | Data Catalog, Business Glossary, Data Lineage, Data Governance, AI Data Assistant |
| Compliance | HIPAA, GDPR, 21 CFR Part 11 |
Because Castor bundles catalog, governance, and AI assistant capabilities into one platform, buyers should expect the quote to reflect the breadth of modules activated. Connector count and the number of data sources ingested are additional cost drivers. Organizations running Snowflake or BigQuery warehouses alongside orchestration tools like dbt and Airflow will want to confirm integration costs are included in the base contract.

Hidden Costs and Considerations
Enterprise data catalog contracts carry costs beyond the subscription fee. Watch for professional services charges for onboarding and initial metadata ingestion. Training costs can accumulate when rolling the platform out to non-technical business users who rely on the natural language search and SQL conversion features.
Additional connectors beyond the base package, premium support tiers, and dedicated customer success resources are common upsell items. Annual contracts with multi-year lock-ins are typical in this segment.
How Castor Pricing Compares
Castor competes in the data catalog and governance space against tools with varying pricing structures. The comparison below uses verified pricing data from direct competitors.
| Tool | Pricing Model | Starting Price | Free Tier |
|---|---|---|---|
| Castor (Coalesce Catalog) | Enterprise (custom quote) | Contact sales | No |
| Alation | Enterprise | Quoted; no public rate | No |
| Secoda | Freemium | $99/month | Yes (1 editor, 500 resources, 2 integrations) |
| Snowplow | Usage-Based | $9/month | No |
Alation sells at the high end of the market and publishes no rate; every deal is quoted. Secoda offers a lower entry point with a free tier for solo users and a Premium plan starting at $99 per month, making it accessible to smaller data teams. Snowplow follows a usage-based model starting at $9 per month, though it focuses on behavioral data pipelines rather than full data catalog functionality.
Castor's enterprise-only approach positions it closer to Alation in terms of target market, serving organizations that need combined catalog, governance, and AI assistant capabilities under a single contract. Teams with smaller budgets or simpler requirements may find Secoda's freemium model a more practical starting point.
