PeerDB
Data Engineering · Databases
Postgres-native ETL that streams change data capture in real time to Snowflake, BigQuery, ClickHouse, S3, and Kafka — up to 10x faster than general-purpose pipelines, managed through a familiar Postgres SQL interface.
cocoindex
AI Development · Data Engineering
An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.
Maltrail
Monitoring · Security
Detect malicious network traffic using 47+ live threat feeds, heuristics, and a fat-client reporting dashboard — no commercial stack required.
OSV.dev
Security
Google's open-source vulnerability database that maps CVEs to exact package versions across 50+ ecosystems with a public API and data dumps.
Rill
Analytics · Data Engineering
The fastest BI tool for humans and agents — define metrics, models, and dashboards as code and query them instantly on ClickHouse or DuckDB.
SafeLine
Security
Self-hosted WAF with a custom semantic detection engine and ML-powered threat analysis that blocks web attacks without cloud dependency.
