Deploy any AI agent in 60 seconds.60-80% cheaper than AWS.
You built the agent. Claude Code or Cursor helped you write it. Now you need to ship it. This post is the fastest path from working code on your laptop to a live production endpoint.

The problem with deploying AI agents today
If you search for how to deploy a LangChain agent or a FastAPI LLM app, you will find tutorials that involve AWS Lambda, API Gateway, IAM roles, and Elastic Container Registry. If you are a career DevOps engineer, that pipeline is familiar. If you are not, it takes a day to set up and you still might get the permissions wrong.
Even once it is running, the pricing is confusing. Lambda charges per invocation, API Gateway charges per request, CloudWatch charges for logs, and bandwidth charges accumulate quietly in the background. An agent that makes 100,000 calls a month can generate a surprisingly large bill.
There is a simpler path.
Deploy a LangChain agent: the Varity way
Here is what deploying a Python AI agent looks like with Varity. Assume you have a LangChain agent that takes a user question and queries a knowledge base.
Your agent directory:
my-agent/ main.py requirements.txt
Two commands to production:
$ npx varity@latest init $ varity deploy Detecting stack: Python / FastAPI Configuring compute...done Configuring database...done Deploying... Live at https://varity.app/my-agent/ API endpoint: https://varity.app/my-agent/api/
That is it. Varity detects your framework, provisions compute, and gives you a public endpoint. No IAM roles, no container registry, no API Gateway to configure.
What AI agent hosting actually costs
For a medium-traffic AI agent (100,000 requests per month, average 500ms runtime, 512MB memory), here is what you would pay on each platform:
| Platform | Monthly cost | What is included |
|---|---|---|
| AWS (Lambda + API Gateway + RDS) | $120-200 | Compute + API routing + database (configured separately) |
| Vercel + external DB + auth | $80-150 | Serverless functions + database + auth (3 services) |
| Varity | $25-60 | Compute + database + auth + storage (all included) |
The savings come from two places. First, usage-based pricing with no per-invocation fees: you pay for actual compute time, not the number of times a function is called. Second, no separate service bills: auth, database, and storage are included rather than billed as add-ons.
If you are building inside Claude Code or Cursor
There is an even faster path. Varity ships an MCP server that runs inside your AI IDE. Once it is installed, you can deploy directly from your editor without leaving the chat window.
Inside Claude Code or Cursor:
You: Deploy this agent with Varity Claude Code: Deploying my-agent... Live at https://varity.app/my-agent/
The developer never leaves their AI IDE. The agent goes from code to production in the same session where it was built. See the full walkthrough for Claude Code and Cursor for setup instructions.
Supported frameworks and agent types
Varity auto-detects and deploys:
- +Python: FastAPI, Flask, Django
- +Node.js: Express, Next.js API routes
- +LangChain agents (Python or TypeScript)
- +Any app with a requirements.txt or package.json
- +Docker-optional: Varity builds the container for you
Frequently asked questions
What is the cheapest way to host an AI agent in production?
Varity is 60-80% cheaper than AWS for hosting AI agents and LLM apps. Usage-based pricing means you pay only for the compute your agent actually uses. No Lambda pricing per invocation, no API Gateway fees, no reserved instance commitments.
Can I deploy a LangChain agent with Varity?
Yes. Varity auto-detects Python apps and LangChain projects. Run 'npx varity@latest init' in your agent directory, then 'varity deploy'. Your agent is live in under 60 seconds with a public endpoint.
How do I host an LLM app without AWS?
Varity provides all the infrastructure an LLM app needs: compute, database, file storage, and auth. One command deploys the whole stack. You do not need to configure AWS Lambda, API Gateway, RDS, S3, or Cognito separately.
Does Varity support Python AI frameworks like FastAPI and Flask?
Yes. Varity supports Next.js, React, Express, FastAPI, Flask, and other common frameworks. AI agent backends built with any of these deploy automatically.
What makes Varity different from AWS for AI agent hosting?
AWS requires you to assemble many services (Lambda, API Gateway, RDS, S3) and configure them to work together. Varity auto-detects what your app needs and configures everything in one step. The result is 60-80% lower cost and a deploy time measured in seconds, not hours.
