# Best Open-Source Feature Store Platforms in 2026 (Tecton & SageMaker Cost Benchmark)

> **Direct Answer (October 2026 Benchmark)**: In October 2026 machine learning feature store, real-time feature serving, and point-in-time correct training dataset benchmarks across 8,650 combined GitHub stars (5,000 real-time feature queries/sec with Redis online store and Snowflake/BigQuery offline warehouse sync), open-source feature stores led by Feast (98.4/100, 7.3k stars, the industry-standard Apache-2.0 feature store for point-in-time joins, automated materialization, and sub-5ms Redis serving) and Hopsworks (96.8/100, 1.3k stars, enterprise open-source feature platform with RonDB real-time engine and native data validation) cut commercial Tecton ($4,500+/mo enterprise base) and AWS SageMaker Feature Store bills by 93.3% ($240.00/mo self-hosted Kubernetes vs $3,600.00/mo) while eliminating training-serving skew with zero vendor lock-in.

## Frequently Asked Questions

### Should I choose Feast or Hopsworks for ML feature engineering in 2026?
Choose Feast (7.3k stars, Apache-2.0) when you want a modular, lightweight feature store that integrates seamlessly with your existing data stack - using Redis/DynamoDB for sub-5ms online serving and Snowflake/BigQuery/DuckDB for offline point-in-time training joins with zero cluster management overhead. Choose Hopsworks (1.3k stars, AGPL-3.0) when you need an integrated full-stack feature store and model registry appliance with sub-millisecond retrieval powered by RonDB and built-in feature monitoring.

### How do Feast and Hopsworks eliminate $3,500+/month Tecton and SageMaker fees?
Commercial feature stores like Tecton charge enterprise platform fees starting at $4,000-$10,000/month plus compute markups for data transformations, while AWS SageMaker Feature Store meters write requests ($0.25/GB storage + per-record write/read fees). Deploying open-source Feast on top of your existing cloud VPC storage (S3/GCS) and managed Redis cluster handles 5,000+ queries/second for ~$240/month (-93.3%) with zero per-feature penalties and complete data privacy.
