Aiden

Aiden is an open source personal AI runtime from Taracod that it describes as a DevOS: an agent that runs on your own machine, takes a goal written in plain English, turns it into a durable job made of steps, and executes those steps with approvals. After each action it checks that the action actually worked, records evidence, verifies the outcome and produces an inspectable verdict, so results can be reviewed rather than taken on trust. It is aimed at developers and technical users who want an assistant that keeps files, memory and tools local. It runs on Windows, Linux and WSL, with macOS supported in API mode, and needs Node.js version 20 or 22. It lets users choose among supported model providers, custom endpoints or Ollama for local models. The package ships an interactive command line runtime and a browser based Workbench. Capabilities that matter include durable memory scoped to the runtime, work state tracked as jobs, attempts, effects, evidence and proof across restarts, grounding in local files such as PDF, EPUB, Markdown and plain text with visible provenance, retry policies with reviewable plans, and reuse of verified outcomes in later work while uncertain results stay marked as uncertain. Aiden is free and open source under the AGPL license, installed from npm or through install scripts for PowerShell and Unix shells. The site publishes no paid plans; any cost comes from the model provider a user connects. The current stable release at the time of writing is version 4.21.2, which introduced Workbench v2 alongside changes to automations and evidence linked learning.
