Do I need a Dockerfile for FastAPI?

Not on while: your API is installed from requirements.txt and started with uvicorn.

Do my pytest tests run?

On while, they run at every deployment, and a version that fails doesn’t replace the previous one.

How much for an API and its database?

On while, €13.75 per month for an API and its database.

Best Python API hosting in 2026: 6 options compared

A FastAPI or Django API can be deployed almost anywhere. What changes is what your AI agent can do there, where your database goes, and the price to get started.

The right choice depends on your app

Do your apps handle health data, or do your customers require certifications? Choose Scalingo: it is ISO 27001 certified and offers health data hosting¹.
Do you want your API live in a few minutes, and France doesn’t matter? Choose Railway or Render: your agent creates the API and its database there through their MCP server^2,3.
Do your Python API and its database need to stay in France, deployed by your AI agent? Choose while: FastAPI and Django are detected without a Dockerfile, and the database is backed up every day.

Host	Your AI agent	The database	In France	To get started
Scalingo	No official MCP server: the command line	Managed PostgreSQL, with point-in-time recovery over 7 to 30 days⁴	Yes⁵	€7.20 for the container and €7.20 for the database, per month⁶

Scalingo, Python in France, without a Dockerfile

Scalingo detects Python without a Dockerfile, and runs your API in France⁵.

Clever Cloud, a French PaaS

Clever Cloud runs your apps in France by default⁹, in many languages.

Render, simple pricing

Render has simple pricing, and its MCP server can’t delete anything³.

Railway, the smoothest for an agent

Railway is one of the smoothest for an agent: your database is created in a single request, and your services stop dead at the spending limit you set¹⁸.

Heroku, the pioneer

Heroku made deploying with git push ordinary, and detects nine languages with no configuration¹⁹.

while, your Python API deployed by your agent

Your agent connects to while over MCP and does the rest: it deploys the app and its PostgreSQL database, its jobs and its storage, follows the logs and fixes things. Sensitive actions, like deleting a production database, wait for your approval, and your agent never sees your keys. Your apps and their backups are hosted in France, by Nextmap.
