A prompt wrapper
Markdown and a chat box
Custom GPTs and most "agent builders".
- No real tools, memory, or agent loop
- Stuck inside someone else's chat window
- Nothing you can brand and sell
A real harness, not a markdown wrapper
Build and sell AI agents as desktop apps.
These aren't prompts dropped in a markdown file, or a thin skin over someone else's chatbot. Agent Spawn builds a real, fully spec'd-out harness (prompts, rules, tools, permissions, memory, and interface) wired into a runtime that actually runs your agent, then packages it into a desktop app your clients install and run themselves. Built to your rules, not a template.

Demo
A custom harness, built with Agent Spawn
Below is a custom harness built with Agent Spawn: workflows a user can make, a chat area, and a control dashboard. Just one example of what's possible.
Run it yourself, or sell it
A harness you can sell, not just run
The serious open-source harnesses are real and powerful, but you run them yourself, as the operator, and you have to be technical. Agent Spawn is the no-code way to turn a real harness into a branded app you sell to clients, who just download and run it.
Run it yourself
A harness you operate
Capable open-source agents like OpenClaw.
- Real tools, memory, and an agent loop
- You set it up and run it yourself
- Built for developers, nothing branded to hand a client
Build and sell
Agent apps you sell
A real harness, packaged as your product.
- Real tools, memory, and an agent loop
- No code: spec it all in your browser
- A branded app your client installs, yours to sell
How it works
From idea to sellable app in three steps
No development environment. No command line. If you can fill out a form, you can ship an agent.
-
1
Pick a template
Start from a ready-made agent: document assistant, bookkeeping helper, support bot, and more. Or start from a blank one.
-
2
Spec out the harness
Set the prompts, rules, instructions, and the exact tools your agent can use, plus its name and logo. Add an AI key, yours or your client’s. Flip the toggles, no code.
-
3
Generate & ship
Download a desktop app for Windows, Mac, or Linux. Use it yourself, or hand it to a client as a finished product.
Why desktop
The agent runs on their computer, not your servers
That one difference removes the hardest, most expensive parts of selling agents.
No servers to run
Nothing to host, monitor, or scale. You ship an app and you’re done. No cloud bill, no uptime to worry about.
Their data, their model
The app talks straight to the AI model on the key you set, so nothing routes through Agent Spawn. Need a setup where nothing leaves the machine at all? Point it at a local model and it runs fully offline.
Hand it off and walk away
Deliver a real installable app, not a fragile setup you have to maintain for every client forever.
No coding, ever
Build everything from a simple browser interface. The hard engineering is already done and baked in.
Bring your own model (BYOM)
Run your agent on any AI you want
Agent Spawn is not tied to one AI company. Plug in your own model with an API key, or run a local model for fully offline, private work. You or your client pay the provider directly, so there is no middleman markup and no lock-in.
- Pay the AI provider directly. No middleman markup.
- Switch models anytime. It is a setting, not a rebuild.
- Use a local model for fully offline, private agents.

Who it’s for
Made for people who want to sell agents
If you’ve been trying to figure out how to build and sell AI agents but you’re not a developer, this is for you. Agent Spawn gives you the product to sell, and you bring the clients.
- You want to sell AI agents, but you’re not a developer.
- You’d rather hand a client a finished app than run a cloud service for them.
- Your clients care about privacy and keeping data on their own machines.
- You want a real product to sell this month, not a six-month build.
