- Schema Weaver – Browser-based PostgreSQL workspace with AI that acts on your schema
I built Schema Weaver because I kept juggling PGAdmin, DBeaver, handwritten migration scripts, and CSV exports across every Postgres project. Everything was disconnected. So I built one browser-based tool that handles the full workflow.
It has two surfaces:
SQL Editor (sql-editor.schemaweaver.vivekmind.com) - Multi-file DDL projects — organise schema like a codebase, editor auto-merges files for compilation - 20-layer schema compiler runs client-side under 50ms: grades your schema A-F, detects missing PKs, RLS gaps, circular dependencies, orphan sequences, unsafe security definers - Live ER diagram auto-generated from SQL, updates keystroke-by-keystroke, handles 1000+ tables - Dijkstra + BFS path analysis to find shortest JOIN path between any two tables - Migration engine with advisory locking, drift detection, 6-phase safe mode for column type changes, tamper-evident audit chain - Resona AI: ReAct agentic loop, 55 purpose-built tools, Table/Group/Global AI contexts, surgical multi-file patching, streams reasoning chain in real time
Data Explorer (data-explorer.schemaweaver.vivekmind.com) - Virtualized grid handles millions of rows with canvas-based smart column sizing (95th percentile sampling) - Column statistics on click: null rate, distinct count, distribution histogram - Resona AI with 40+ tools: natural language to SQL, charts, anomaly detection, PPTX/PDF report generation - Zero exfiltration: row data streams directly from your database to your browser, never touches our servers - Read-only by default, automatic PII masking
Full PostgreSQL 12-17 support: partitions, RLS, composite types, domains, materialized views, PL/pgSQL, extensions.
No install. No desktop app. Live demo database included so you can try without connecting your own instance.
Tech stack: React/TypeScript frontend, Node.js backend for connections, Python/FastAPI for the AI agent layer, AWS Bedrock for model routing.
Looking for honest technical feedback on the compiler accuracy, agent reliability, and anything that breaks.
