PgDesigner
Visual PostgreSQL schema designer with diff engine
What it does
PgDesigner is a visual schema designer built exclusively for PostgreSQL. Design schemas on an ERD canvas (120+ tables), generate production-ready DDL for PostgreSQL 18, compare versions with hazard-aware diff engine, and validate with 66 lint rules — all in a single binary. No cloud, no account, no telemetry. All data stays on your machine. Free for personal use. $19 one-time for commercial.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
