AI coding sandbox powered by Firecracker microVMs, pre-baked with Claude Code and Codex. Spins up isolated, disposable cloud dev environments in seconds so agents can safely execute arbitrary code, install dependencies, and iterate on a real Linux filesystem without escaping into the host.

Serverless email inbox built on Cloudflare Workers with a token-authenticated REST API, full-text search, and an MCP skill that lets AI agents read, search, and send mail directly. Runs entirely at the edge with zero cold-start cost and no dedicated mail server to operate.

Zero-GUI voice input for macOS — hold a hotkey, speak, and cleaned text lands in whichever app has focus. Audio streams to Doubao ASR in real time, then an OpenAI-compatible model corrects punctuation, spacing, and terminology using plain-text prompts and a user dictionary before the result is pasted back. Native Objective-C shell + Rust core, no Electron, under 15 MB on disk.

AI-powered image restoration tool that intelligently removes stains, blemishes, and unwanted objects in a single click. Wraps a diffusion-based inpainting model behind a minimal UI so non-technical users can clean up old scans and photos without opening Photoshop.

Free, open-source DeepL Translation API proxy with high-concurrency support. 8.4k GitHub stars and powers translation features in dozens of downstream apps, browser extensions, and Immersive Translate-style tools worldwide.

Visual network route tracing tool — a modern alternative to traceroute with built-in IP geolocation, ASN lookups, and map visualization. 7.6k GitHub stars and a staple in the Chinese networking / BGP community for diagnosing cross-border latency.

Local encrypted secret manager using Argon2id key derivation with AES-256-GCM authenticated encryption. Zero cloud dependency — secrets never leave the device, and the vault format is a single portable file suitable for syncing via any storage of your choice.
