6 free alternatives to MotherDuck

Hex gives you a free Community plan with a notebook agent trial, connections to any data source, all cell types, up to 5 notebooks, and Small compute. That makes it a good fit if you want a collaborative analysis workspace rather than a warehouse-first product. It beats MotherDuck on interface flexibility and data-source breadth, since you can work across sources in notebooks instead of centering everything on DuckDB storage and compute. It falls short on raw warehouse-style capacity, because the free plan is notebook-capped and does not offer the same storage-oriented free allowance. Switch if your team wants analysis and sharing first, not a cloud warehouse.

• Beats MotherDuck: More flexible analysis workspace and any data source connections
• Falls short: Less warehouse-style storage and compute headroom
• Who should switch: Switch here if you want notebook-based analytics with light free usage rather than a small cloud warehouse.

Cube's free plan includes access to connect any data source, model data in the semantic layer IDE, explore in workbooks, publish workbooks as dashboards, use the semantic model agent, use the workbooks and dashboards agent, and access analytics chat. It also gives up to 5 workbooks, 1,000 requests per day, and community support. It beats MotherDuck on semantic modeling and BI delivery, because you get a governed analytics layer with dashboards and chat rather than just database-style compute and storage. It falls short on storage and compute capacity, since the free tier is defined around workbooks and daily requests, not a warehouse-sized free pool. Switch if you care more about BI workflows than database hosting.

• Beats MotherDuck: Semantic layer and BI dashboard workflow
• Falls short: Less direct storage and compute capacity
• Who should switch: Switch here if your free use case is governed BI and chat, not data warehouse storage.

Tinybird's free plan includes shared infrastructure, 0.25 vCPUs, 1 thread per request, 10 QPS maximum, 10 GB of included storage, community support, Kafka topic and pipe limits, and basic job and branch limits. It is the closest fit if you want a managed analytics backend with API-style query serving and modest included storage. It beats MotherDuck on real-time analytics plumbing, because the free tier includes request and throughput controls plus ingestion and pipeline concepts that are useful for operational analytics apps. It falls short on ease for broad SQL warehouse use, since the free plan is heavily constrained around throughput and infrastructure size. Switch if your workload is event-driven and API-oriented.

• Beats MotherDuck: Real-time analytics plumbing and request throughput controls
• Falls short: Less free compute flexibility for general SQL warehouse work
• Who should switch: Switch here if you are building an API-backed analytics app with streaming and ingestion needs.

Othor AI's free tier includes 1 active agent, 1 active datasource, 1 user, 1 dashboard, and self-service support. It is the simplest option here for a very small team that wants an AI BI layer without managing warehouse-style concepts. It beats MotherDuck on opinionated BI simplicity, because the free plan is centered on a single agent, datasource, and dashboard rather than storage and compute quotas. It falls short badly on team size, storage, and compute, since the free tier is much tighter for shared use and data volume. Switch if you need a single-person or proof-of-concept dashboard workflow, not a warehouse.

• Beats MotherDuck: Simpler AI BI setup for a single user and dashboard
• Falls short: Much less room for team, storage, and compute growth
• Who should switch: Switch here if you only need a one-user BI proof of concept.

Dreambase's free tier gives access to 1 user account, 1 dashboard, 1 Supabase schema, Supabase Health Reports, and Slack community support. It is best when your data lives in Supabase and you want a focused analytics layer on top of that one source. It beats MotherDuck on source specificity, because the free tier is tightly aligned with Supabase workflows and health reporting rather than a general warehouse allowance. It falls short on capacity and flexibility, since the free plan is limited to a single user, dashboard, and schema. Switch if your whole stack already lives in Supabase and you want a narrow free layer on top.

• Beats MotherDuck: Better fit for Supabase-native analytics and health reports
• Falls short: Far less free capacity for users, dashboards, and sources
• Who should switch: Switch here if your source of truth is a single Supabase project.

Preset's free Starter plan includes 1 workspace, up to 5 users, unlimited dashboards and charts, 40+ visualization types, a no-code chart builder, a collaborative SQL editor, semantic layer access, and docs and tutorials. It beats MotherDuck on dashboarding and collaboration, because the free tier is built for a small team to create and share BI assets inside one workspace. It falls short on warehouse-style storage and compute, since the free offer is scoped around BI workspace limits rather than data residency or engine usage. Switch if your team wants a conventional BI frontend with SQL editing and charting.

• Beats MotherDuck: Unlimited dashboards and charts with better BI collaboration
• Falls short: Less direct free storage and compute for warehouse workloads
• Who should switch: Switch here if you need a lightweight BI workspace for a small team.
