The queue.
Tool entries the maintainer is actively writing or queued to write. No promised dates — these land when their schema can be fully populated from documentation. Anything already indexed above is filtered out at build time, so nothing appears here and in the live roster at once.
Beyond observability.
"Scoped" means the cluster taxonomy for the vertical is being drafted — what the sub-clusters are, what fields the schema needs, what counts as a legitimate entry. Tool entries are not yet imminent.
- BI & analytics consumption
- Ingestion & ELT
- Transformation
- Orchestration
What we won't index.
- Pure spreadsheet or notebook tools that aren't part of a production data stack.
- Tools archived or unmaintained for 24+ months without a clear successor.
- Per-tool user reviews and ratings — the catalog describes capability, not satisfaction.
- Detailed pricing for tools whose only published price is "contact sales," beyond the existing flag.
Why coverage looks the way it does.
Coverage is built breadth-first within a vertical before moving to the next one. The bet: a complete data observability vertical is more useful than three half-populated verticals. The constraint: this is a one-person project, so depth comes faster than breadth, and breadth comes faster than horizontal expansion.
If you'd like a tool indexed sooner, send a note via corrections — though placement requests don't change the queue, awareness of teams actively evaluating a tool informs prioritization.
