Could you build this?
Partial While standard CRUD catalog interfaces can be vibe-coded, engineering a zero-external-dependency, single-binary data catalog with embedded search, metadata storage, and lineage processing requires careful systems design.
What it would actually take: The stack would typically be written in Go or Rust, leveraging embedded engines like SQLite or DuckDB for metadata alongside embedded full-text engines (e.g., Bleve or Tantivy). The challenging parts include robust automated connector ingestion from heterogeneous data sources without external queue brokers (like Kafka) and efficient graph storage for data lineage and schema evolution.
Discussion
20 comments analyzed.
Competitors mentioned: Amundsen, Open Metadata, Snowflake native catalog, dbt, Tableau
Concerns raised: Metadata becomes outdated without enforcement mechanism, Documentation burden on developers reduces adoption, Lacks enterprise features like SSO/SAML governance, Cross-storage lineage discovery is complicated, Plugin system requires Go expertise; LLM-generated code risky
Feature requests: Schema versioning with UI navigation, Native integrations beyond Airflow, Column-level lineage, External plugins (not compiled into binary), SQLite/D1 plugin
