About Lumen

Native desktop data atelier for databases, logs, and keys.

Lumen is a high-performance, native desktop application ("data atelier") built for developers, data engineers, and analysts to view, edit, compare, and query databases, dumps, and giant log files in one place. Built with a modern tech stack (Tauri 2 + Rust + React 19 + TypeScript + Tailwind CSS), Lumen offers native performance, memory safety, and an extremely fast user experience. Key Features: Multi-Engine Support: Native integration with SQLite, DuckDB, JSON, JSONB, MongoDB, Redis, and Flutter Hive boxes. Instant Log Viewer: Read gigabyte-scale .log and .txt files using memory mapping (memmap2) with real-time string indexing without freezing the UI. Diff & Compare: Visual side-by-side and structural diffing between two data sources. Schema & Migrations: Visual ER/graph schema diagrams and in-app DDL migration runner for SQLite and DuckDB. Data Grid & In-place Editing: Virtualized high-speed table with inline cell edits, tree views, and raw SQL query execution. What is Included in the Sale: Full source code repository (Rust backend + React frontend). Complete IP and branding rights. Build configurations and setup documentation.

Reason for selling

I built Lumen to solve the multi-engine data & log browsing problem with a top-notch UI and performance. I am now focusing on other core projects and want to hand this over to someone who can launch, market, and monetize it effectively.
