Castov
Local-first desktop automation engine with on-device AI
About
Castov is a local‑first desktop automation engine that runs entirely on your machine, keeping all data private. It offers a web UI, command‑line interface, and an MCP server that connects to local AI models such as Cursor and Claude. With zero‑data logging, built‑in JSON‑to‑TypeScript conversion, multi‑timezone cron jobs, and cryptographic pipelines, it unifies scripting, scheduling, and secure data handling in one tool.
The case
Who it is for
Developers and power users who need to automate tasks locally without sending data to the cloud, and who want a flexible web and CLI interface for scripting.
What is broken today
Before Castov, developers who wanted to automate tasks typically relied on cloud‑based services that log data or on custom scripts that lack a unified interface. Existing solutions either expose sensitive information or require internet connectivity, limiting privacy and flexibility.
What it does about it
Castov is a 100% client‑side automation platform. It runs locally, providing a web UI, CLI, and an MCP server that integrates with local AI models like Cursor and Claude. The tool offers zero‑data logging, JSON‑to‑TS conversion, multi‑timezone cron jobs, and cryptographic pipelines, all without external data transmission.
Why not the obvious alternative
Unlike cloud‑based platforms, Castov never sends data outside your machine, ensuring privacy. It also allows you to run AI models offline through the MCP server, and bundles JSON‑to‑TS conversion and multi‑timezone scheduling in a single, local tool, which most alternatives separate into multiple services.
