Crypto research agent. Drop a ticker or a contract address and get a structured breakdown in seconds: on-chain data, socials, news, red flags.

Live visualizer for whatever your Mac is playing. It taps the output mix, so Spotify, a call or a game all work the same. Lives in the menu bar — six modes, ten palettes, no dock icon, no account.

Media editing toolkit with one Python core and three faces: a CLI with interactive TUI, an HTTP API, and a Telegram bot. Crop, compress, convert, cut — same pipeline everywhere.

Self-hosted toolbench, every format you need: file conversion, PDF tools, media downloader, URL screenshots, DNS dig, IP inspector, speed test and a private pastebin. Files never leave your machine.

One CLI for the crypto world — built for AI agents, pleasant for humans. Prices, balances, gas, DeFi protocols and Hyperliquid perps from a single tool, zero API keys.

Self-hosted personal finance tracker: expenses, income and subscriptions with charts and customizable themes.
