Running agentic workflows locally works well for experimentation, but it introduces a reliability problem. If a computer shuts down or the internet connection drops, workflows stop running. For mission-critical or team-based use, those workflows need to live in the cloud.
This article explains how Anti-Gravity agentic workflows can be deployed to the cloud using Modal, allowing them to run continuously and be triggered remotely.
TL;DR
- Problem: Local Anti-Gravity workflows stop when a machine or connection fails.
- Solution: Host agentic workflows in the cloud using Modal.
- Outcome: Always-on workflows accessible from anywhere.
Why cloud hosting matters for agentic workflows
Anti-Gravity runs locally by default. That makes it free and fast to experiment with, but it also means workflows depend entirely on a single machine.
For workflows that must:
- run continuously
- be accessed by a team
- handle production workloads
cloud hosting becomes necessary. Modal provides a way to deploy these workflows without maintaining servers manually.
What Modal provides
Modal is a serverless platform that allows code and workflows to run in the cloud on demand. New accounts include free credits, which are sufficient for testing and small production workloads.
Modal operates on a pay-per-use model. Workflows spin up when triggered and shut down automatically afterward.
Preparing Anti-Gravity for cloud deployment
The setup begins by creating a new Anti-Gravity project from scratch. A blank folder is created locally, and a single markdown file is added to define instructions for Anti-Gravity.
This instructions file contains configuration logic that tells Anti-Gravity how to connect to Modal. The content does not need to be fully understood line-by-line. Its purpose is to establish the connection correctly.
Once saved, Anti-Gravity reads the file and prepares the integration automatically.
Creating a simple agentic workflow
To verify the setup, a minimal workflow is created. The workflow accepts a user name as input and returns a short response that greets the user by first name.
This example confirms:
- Anti-Gravity can generate the workflow logic
- Modal can host and execute it
- The workflow can be triggered externally
Connecting Anti-Gravity to Modal
During setup, Modal requires the creation of an API token. This token authorizes Anti-Gravity to deploy and manage workflows in the Modal environment.
Once the token is created and accepted, Anti-Gravity completes the integration and generates a live endpoint URL.
This endpoint becomes the public interface for the workflow.
Triggering workflows via HTTP
With the cloud deployment complete, the workflow can be triggered using a simple HTTP request. The endpoint accepts parameters and returns structured responses.
This makes it possible to:
- call workflows from other automation tools
- trigger workflows from browsers
- integrate with external systems
The workflow can also be tested directly by opening the endpoint URL in a browser.
Scheduled execution
In addition to HTTP triggers, workflows can be scheduled. Anti-Gravity can be instructed to change the trigger type so the workflow runs on a defined schedule, such as every few seconds or minutes.
Scheduled workflows are useful for:
- polling external systems
- recurring data collection
- periodic synchronization tasks
The output can be sent to other systems using webhooks.
Local vs cloud execution trade-offs
Both local and cloud execution have advantages and limitations.
Local execution
- Free
- Instant startup
- No authentication required
- Dependent on a single machine
Cloud execution
- Always available
- Accessible by teams
- Pay-per-use pricing
- Startup latency due to server spin-up
- Requires authentication and security
Long-running workflows may also encounter timeout limits in cloud environments. In those cases, workflows can be split into multiple stages.
Security considerations
Cloud-hosted workflows expose public endpoints. Without authentication, unauthorized users could trigger workflows and consume resources.
Securing endpoints is essential, especially when workflows interact with paid APIs or sensitive systems.
Verdict
Hosting Anti-Gravity agentic workflows in the cloud removes reliability limitations of local execution. Modal provides a low-friction way to deploy these workflows without managing infrastructure manually.
For experimentation, local execution is sufficient. For production, collaboration, and mission-critical automation, cloud deployment becomes a practical requirement.
FAQ
Is Modal free to use?
New accounts include free credits suitable for testing and small workloads.
Do workflows run continuously in the cloud?
No. They spin up on demand and shut down after execution.
Can cloud-hosted workflows replace local ones?
Yes, for production use, but local execution remains useful for development.
