MotherDuck versus DuckDB
Compare	MotherDuck	DuckDB
Verdict	Depends	Worth it
Best for	Startups and small data teams	Data engineers querying Parquet/CSV locally
Who it's not for	Petabyte-scale enterprises	Teams needing concurrent multi-user writes . DuckDB is single-process, in-process
Privacy	No known public vulnerabilities found in the sources reviewed.^⁹	Actively patched open source, but a 2025 npm supply-chain compromise and encryption crypto flaws were disclosed.
Support quality	Vendor claims engaged support; thin independent evidence	Community-driven; frequent releases, no vendor SLA
Public sentiment	Users love the simplicity and sharing, but grumble about the 2026 price hike and whether it belongs in production.	Engineers praise its speed and simplicity, but some report slow results when their workload doesn't fit its single-node design.¹⁶
Biggest gotcha	Feb 2026 hike killed the $25 plan; entry paid tier is $250 Business^⁷	September 2025 npm package compromise (CVE-2025-59037) . pin trusted versions
