What does it cost to run AI agents in my app?

Building, testing and staging are free. During the apps preview, hosting is free too, under fair use: one live app per organization, within the hosted limits. We give at least 60 days' notice by email before any charge, and nothing is charged until you choose a plan. For more than one live app, contact us. You use your own model key and pay your model provider: Kindgi never resells model use.

Where do the agents live?

In your repo, in a kindgi/ folder next to your app's code. They're TypeScript, and their tools can import your app's own modules. You and your coding agent can change anything, from the instructions to the approval rules to the model.

How do people use the agents?

Through your app. Your route handlers start runs and stream each step to your pages with @kindgi/sdk. The people you choose approve on a page in your app, through the same client, or in their inbox in the Kindgi console.

For TypeScript teams · Next.js

Build and manage custom AI agents for your app.

Kindgi is the agent framework for production. You build the agents your app needs, from a helpdesk agent that answers from your app's own data to refunds that wait for a person's approval. They live in your repo, next to your app's code. Kindgi has everything you need to make it happen.

How do you work with Kindgi?From your laptop to your users.

Add Kindgi to your app.
One command in your app's root adds a kindgi/ folder for agents, tools, guardrails and flows, with tests and the skills your coding agent needs.
Shape it with your coding agent.
It's TypeScript, and tools can import your app's own modules. You and your coding agent can change anything, from the instructions to the approval rules to the model.
Connect it to your app.
Your route handlers start runs and stream each step with @kindgi/sdk. Kindgi calls your app back with signed webhooks.
Test it before it goes live.
kindgi test runs the pack's tests; kindgi dev runs Kindgi on your laptop, beside next dev.
Your team approves what matters.
The people you choose approve on a page in your app, or in their inbox in the Kindgi console.
You keep it running.
In the Kindgi console you see every run, every decision and what each run costs. When needs change: change the code, test, deploy.

The numbers are the steps above. Swipe to see all of it.

Try it, then go live.Free while you build, test and stage. Free hosting during the apps preview.

Try it

Free to build, test and stage

Add Kindgi to your Next.js app: in the app's root, one command adds the kindgi/ folder, with tests and the skills for your coding agent.$ npx @kindgi/cli init
Get access to the runtime: sign in with GitHub at access.kindgi.com. You get a pull token and a license key, with the commands that set them up.
Run it on your laptop with kindgi dev, beside next dev. You need Docker and a model API key (Anthropic, OpenAI, Google Gemini, etc.).
Keep building with your coding agent: it knows what to do, since every pack comes with instructions and Kindgi's skills for it.
