The integrations directory lists 525 sources, including Salesforce, Stripe, PostgreSQL, Shopify, and Google Analytics. Pipelines ingest CSV, Parquet, JSON, and NDJSON files, and support log-based change data capture for Postgres, MySQL, and Oracle where supported. Definite also supports MCP clients such as Claude, ChatGPT, and Cursor, providing schema, lineage, and semantic context. Users can build custom data applications and search millions of rows in a browser using DuckDB-Wasm. Security measures include TLS 1.2+ encryption in transit, AES-256 encryption at rest, and role-based access controls. The Free plan has two users, two connectors, 1 GB of storage, five monthly credits, and daily sync. Standard costs $250 a month and includes 100 monthly credits and hourly sync.
