Building modern web applications usually means stitching together multiple backend services: a database, API layer, authentication, realtime sync, scheduled jobs, and file storage. That stack quickly becomes complex, especially for indie developers, startups, and small teams trying to move fast. Convex takes a different approach. It combines a reactive database,

Apache Superset vs Metabase vs Redash: Which Open-Source BI Tool to Self-Host in 2026?

If you're picking an open-source BI tool in 2026, the shortlist is short: Apache Superset, Metabase, and Redash. Same SQL backend, same CSV upload, same "make a chart, share a dashboard" promise. The differences live in who owns the project, who the tool is actually built

Self-Hosted Weekly: Week 18, 2026. Mistral 3.5 Lands, Hashimoto Quits GitHub, cPanel CVSS 10

Dify vs Langflow vs Flowise: Which Open-Source LLM App Builder Actually Ships to Production?

Every comparison of Dify, Langflow, and Flowise asks the same question: which one is easiest to start with?

ClickHouse vs DuckDB: Which Analytical Database for Embedded vs Distributed Workloads in 2026?
