Denkzeug

[ˈdɛŋkˌtsɔʏ̯k] “DENK-tsoyk” German, noun

A Denkzeug is an object that is not part of the body of a living or artificial organism, used to extend the functions of the mind in order to achieve a distant goal.

A tool for thought. Quite literally.

Agents Sessions Workflows

A small illustration of things working together.

A workspace for
your AI agents.

Denkzeug is an open-source app you run on your own server. Chat with agents that use tools and create files, then turn useful work into repeatable workflows or small apps.

Make it on your computer.Agents, tools and the files you create, in one place.

Pick it up on your phone.The same work, wherever you are.

Real app screenshots, captured with demo data. Click marked areas to switch screens—not a redrawn interface or a live session. Both app clients connect to the same self-hosted instance.

Your tools.
Your terms.

A place for your agents, your ideas and the work that comes next. Not another place to get locked in.

Free

Open source. Self-hosted. The whole thing, not the useful half. Run it on your own terms, read the code, change what you need.

No feature tiers. No permission needed.

Remote

At home, on a VPS, wherever you like. Your agents work there. You connect from your phone or computer, and the work keeps going when you switch your device off.

Your server stays on. Your screen doesn’t have to.

Extensible

Your agents, skills, workflows and system prompts. Connect your own models and MCP tools. Built on the lightweight Pi foundation, with room to make it yours.

You choose the pieces. You keep control.

Thought is
only the start.

Make something once. Give it a process.
Put a small interface on top.

An idea becomes a thing

Create

Software, a presentation, a CAD drawing. Go from a conversation to something you can open, edit and use.

With ArtCraft, your agents work in native creative tools—not just a text box.

Meet the creative tools
A good process, kept

Process

Code for the predictable parts. Agents for the parts that need thought. Combine them in deterministic workflows you can read, repeat and schedule.

The same agents and MCP tools you use every day, working without you having to be there.

Look inside a workflow
Your own way in

Show

A dashboard, a small control panel, a new way to work. Build miniapps that bring your tools and data together.

Trigger a workflow. Connect a service. Turn something you imagined into something you can actually use.
