AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Modal is a Python SDK that lets you run serverless cloud compute jobs on-demand from your local scripts, handling infrastructure provisioning and execution without managing servers directly.

Installation is straightforward with low friction—a pure-wheel distribution with 13 well-established runtime dependencies. The project shows strong maintenance signals: released 1 day ago, active status, 501 GitHub stars, and continuous commits through August 2026.

Licensed under Apache-2.0 (permissive), allowing free use, modification, and distribution with minimal restrictions—suitable for both commercial and open-source projects.

Usage

pip install modal
python3 -m modal setup

import modal
app = modal.App()

@app.function()
def hello():
    return "Hello from Modal"

if __name__ == "__main__":
    print(hello.remote())

Requires Python 3.10–3.14; you must run `python3 -m modal setup` to authenticate with a Modal account before executing remote functions.

Verdict: Modal is a well-maintained, actively developed serverless compute SDK with permissive licensing and low installation friction. It has no known vulnerabilities and sits in the top 1000 PyPI packages. The primary consideration is the Python version requirement (3.10–3.14) and the need for account setup before use.
