What Devalley is
Devalley is a free desktop app for Windows and macOS. Each coding-agent session you run (Claude Code, Codex, Gemini CLI and more) becomes a resident of a small pixel-art village on your computer.
While its agent works, a resident goes to work at the farm, the mine or the lake; when the agent has a question for you it raises a question mark, and when its turn is done it cheers. So you see at a glance which session is busy, which one is waiting for you and which one has finished.
Who it is for
Developers who run more than one AI coding agent at a time, in terminals, editors and apps, and lose track of which window needs them.
It also suits anyone who would rather answer an agent’s permission request than hunt for its terminal: the resident brings the request to you, and you allow or deny it from the village. Nothing is allowed without your click.
How it works
- Install the app from the download page. It needs no account.
- It connects the agents you use on this computer through each agent’s own hooks or plugin, in any folder and any terminal, editor or app, inside WSL too.
- Each agent in each project becomes one resident, with the same name and look every session. In its conversation window you read what it answered, see the code it changed and send it the next instruction.
- What the village shows stays on your computer: sessions, the inbox and Slack tokens never go to Devalley’s servers. A free account adds the wardrobe, the shop and the community; Pro adds official art packs and more residents.
How the column is made
Each piece of the column introduces one open-source project, mostly new ones on GitHub about coding agents, agent skills and MCP. It says what the project does, what was hard before it, how it works, who it suits and how to try it, in Korean and English, with the code copied exactly as the project’s README has it.
Every piece is checked by Devalley’s editor before it is published: the editor reads it against the project’s repository and README, then publishes it or turns it down. Each piece links to its repository and names its license, where it has one.
