miniMDM vs Tamr

miniMDM is a self-hosted application for managing business records such as customers, products, locations, and custom data objects. It is intended for teams whose reference data has outgrown spreadsheets but does not call for a multi-year enterprise MDM rollout. Teams define objects in YAML or JSON, including fields, types, references, and required flags. Records can progress through draft, active, and retired states; each edit creates a version that users can review or restore. Viewer, Editor, Publisher, and Admin roles have per-schema grants. A REST API comes with an OpenAPI specification, and webhook callbacks report lifecycle changes. An inbound receiver accepts upstream records as drafts for review. Bulk import and export support CSV, TSV, and JSON, with template-assisted imports and optional upsert-by-key. The MIT-licensed project is described as free to use, with no per-seat licensing or separately purchased modules; its plan is free. It runs on premises, uses PostgreSQL, and is built with FastAPI and SQLAlchemy. The site describes zero telemetry and says password changes end the account’s open sessions.

Tamr is an AI-native master data management platform that turns information from disparate sources into curated records for analytics, AI, and operational work. Its machine learning identifies duplicates and inconsistencies, combines records into golden records, and uses human feedback for ongoing improvement. Data products cover customers, contacts, suppliers, products, locations, healthcare providers, and healthcare organizations, with custom products available. An API-first design includes two-way connectors for AWS, GCS, ADLS2, Snowflake, OneLake, and BigQuery, plus iPaaS connections. Enrichment integrations include Dun & Bradstreet, PitchBook, ZoomInfo, and NPPES. MCP and bring-your-own-agent support allows retrieval, validation, updates, duplicate resolution, and downstream actions. Fees are based on output golden-record volume, not input records; users are unlimited. Subscriptions include onboarding, training, and standard support. Pricing is on request.
