Free API hosting for REST and GraphQL APIs

Deplexo runs persistent containers instead of serverless functions, so there are no cold starts and response times stay consistent. WebSockets work too, which suits REST APIs, GraphQL servers, and real-time backends.

• Express.js
• FastAPI
• Flask
• Django REST Framework
• Go net/http
• Ruby Sinatra / Rails API

Any framework that runs in a container works.

1. Push your API code to GitHub.
2. Connect the repo on Deplexo.
3. Add env vars (database URL, API keys) in the dashboard.
4. Deploy. Your API goes live on its subdomain.

Express.js

framework: node
start: node server.js
port: 3000

FastAPI

framework: python
start: uvicorn --host 0.0.0.0 --port $PORT main:app
port: 8000

Serverless platforms spin down after a period of inactivity, so the next request waits through a cold start. On Deplexo your API runs in a container that stays on, and the first request is as fast as the thousandth.
