Different ways to build the same bot.
The “best” platform depends on what must stay running, what must be public, where state lives and which software the bot depends on. Start with the job, not the technology name.
Quick decision
Use a Worker for short event-driven web logic, a VPS for long-running Python/Node processes, MetaTrader for EAs that belong inside MT4/MT5, a local PC for learning and supervised development, or a hybrid when you want a public edge plus a private persistent service.
Compare the main options
| Method | What it is | Good for | Main trade-off |
|---|---|---|---|
| Cloudflare Worker | Code that runs when requests or scheduled triggers arrive | Webhooks, validation, routing, lightweight APIs | Not a traditional always-open process |
| Linux VPS | A virtual server you administer | Python, Node, WebSockets, databases, 24/7 loops | You maintain the server |
| Windows VPS | A remote Windows machine | MT5 + Python and Windows-only software | Usually more overhead than Linux |
| MetaTrader EA | MQL code running inside MT4/MT5 | Platform-native strategies and execution | Depends on MetaTrader runtime |
| Local PC / mini-PC | Software running on hardware you control | Learning, local integration, supervised use | Power/network/hardware are your responsibility |
| Hybrid | Two or more runtimes with separate jobs | Public Worker + private VPS, signal service + execution service | More components to monitor |
Why hybrid designs are common
A public webhook receiver and a long-running strategy process have different needs. The receiver should be small, defensive and easy to expose. The long-running service may need local state, persistent connections and heavier libraries. Splitting them often makes failures easier to isolate.

External API / brokerQuestions to answer before choosing
- Must the process stay alive continuously?
- Does it require Windows or MetaTrader?
- Does it need a public HTTPS endpoint?
- Does it need a local database or long-lived WebSocket?
- Can your home PC be allowed to switch off?
- How will the service restart and how will you know it is healthy?
Common questions
Do I need a VPS for every bot?
No. A webhook-only service can fit a Worker, an EA can stay inside MetaTrader, and local development can run on your PC. A VPS becomes useful when you need a persistent process independent of your home computer.
Can a Worker and VPS be used together?
Yes. A common design is to let the Worker receive public requests and let the VPS keep long-running state, connections and heavier logic.
What should decide the architecture?
Start with runtime requirements: continuous or event-driven, Windows or Linux, public endpoint or private service, state requirements, external platform dependencies and restart behavior.
