Rill
Code-driven operational BI platform built on DuckDB. Rill uses YAML definitions for data sources, models, dashboards, and metrics — all version-controlled in git. Connects to databases, warehouses, and local files. DuckDB powers fast local analysis without a separate data warehouse. Rill Developer (local) + Rill Cloud (hosted sharing) model. Positioned as 'analytics-as-code' — bring BI into the software development workflow with git-based version control for all analytics artifacts.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Apache 2.0 open source. SOC2 for Rill Cloud. Local mode has no security surface beyond OS. Rill Cloud uses Google OAuth. Credentials for data sources stored in .env files (must be excluded from git).
⚡ Reliability
Best When
You're a technical team wanting git-version-controlled, code-driven analytics on small-to-medium datasets with fast iteration and DuckDB performance.
Avoid When
You need enterprise BI features, large-scale data warehousing, or a GUI for non-technical business users — use Metabase, Tableau, or Lightdash.
Use Cases
- • Build agent performance dashboards with Rill's YAML-defined metrics that track key agent KPIs with automatic drill-down
- • Create operational analytics on top of DuckDB without a separate data warehouse using Rill's in-process analysis engine
- • Version-control all analytics definitions (sources, models, dashboards) in git alongside application code using Rill's code-first model
- • Share interactive dashboards with stakeholders via Rill Cloud without complex BI infrastructure setup
- • Query local CSV/Parquet files or cloud storage with sub-second response times using DuckDB's columnar engine
Not For
- • Enterprise BI with complex user management, row-level security, or pixel-perfect formatting — Tableau, Looker, or Power BI for enterprise BI
- • Very large datasets (>100GB local) — DuckDB has memory limits for in-process analysis; use Clickhouse or BigQuery for petabyte-scale
- • Teams wanting GUI-first BI tools — Rill requires YAML definitions; non-technical users need Metabase or Redash
Interface
Authentication
Rill Developer: no auth (local). Rill Cloud: Google OAuth for login. Organization-level access control for shared dashboards. No API key auth for programmatic access.
Pricing
Rill Developer is Apache 2.0 open source and free. Rill Cloud (hosted sharing and embedding) has a free tier and paid tiers. Most development is local; Cloud is for sharing.
Agent Metadata
Known Gotchas
- ⚠ Rill's YAML schema is specific to its data model (source, model, dashboard components) — agents generating YAML must follow Rill's exact schema, not generic YAML
- ⚠ DuckDB's in-process model means large queries consume Rill's host process memory — agents triggering complex queries on large datasets may cause Rill to run out of memory
- ⚠ Rill Cloud's API is not fully public documented — programmatic dashboard manipulation requires using the file-based YAML approach and git sync, not REST API calls
- ⚠ Source connections (databases, cloud storage) require driver configuration in YAML — agents adding new data sources must know the connector schema for each source type
- ⚠ Rill's dashboard metrics are pre-aggregated at model level — ad-hoc queries that don't map to defined metrics require raw SQL via the explore interface
- ⚠ Rill Cloud embedding (iframe) requires specific CSP headers — agents building apps that embed Rill dashboards need to configure CORS and CSP for their hosting domain
