Best Data Federation Software in 2026

Data federation software can help you query data across sources, making query features, access, and deployment useful points to compare. Check SQL querying, scheduled queries, and query result cache, then consider row-level security and API access. Cloud-hosted and self-hosted describe deployment choices; free-plan availability and paid-from pricing add cost context. Denodo Platform, Stardog, and Apache Drill are among the options shown. Consider the queries you need to run, how results should be accessed, and what access controls are relevant, then compare the listed capabilities and deployment details against those requirements.
