What stands out
A quick read of the recorded project description.
The repository includes a Procfile that declares how the platform starts the app
Locally started with python main.py, listening on port 8080 by default
Deployment command is velixir deploy; dependencies and image are built server-side
Code is under the MIT license and may be used, modified, used commercially, and distributed for free
Template Details
This is a Python service launcher template for the velixir platform. Routing is handled by Flask, gunicorn is used as the server in production, and a Procfile is provided in the repository to tell the platform how to start the application. The README describes its positioning as "what almost every Python service eventually grows into, minus the parts you would delete anyway."
To run locally, install the dependencies from requirements.txt and execute python main.py, then visit http://localhost:8080. Deployment is done via velixir deploy, with dependency installation and image building performed on the platform's server side.
The template emphasizes two constraints: first, the Procfile must be present, otherwise the platform will fall back to the Flask development server, which is single-threaded and outputs warnings; second, it must bind to $PORT on 0.0.0.0. velixir injects PORT, and binding only to the loopback address may build successfully but will fail health checks.
The code is released under the MIT license and may be used, modified, used commercially, and distributed for free; the repository does not provide further business functionality descriptions, and the template itself does not include modules such as databases or authentication.

Is it right for your project?
Use Cases
- Quickly create a deployable Python web service starting point on the velixir platform
- Serve as a reference example of a minimal Flask + gunicorn runtime structure
- A Python project scaffold that requires a Procfile and port binding conventions
Suitable For
- Developers preparing to deploy Python services on velixir
- Those who need a minimal working starting point combining Flask and gunicorn
- Projects that wish to freely modify and distribute code under the MIT license
Getting started & customization
Use these recorded setup notes alongside the repository instructions for your chosen version.
- 1
Local run: pip install -r requirements.txt then execute python main.py, visit http://localhost:8080
- 2
Deployment: run velixir deploy; the platform installs dependencies and builds the image
- 3
The Procfile must be kept, otherwise the platform will start the Flask development server (single-threaded and outputs warnings)
- 4
Must bind to $PORT on 0.0.0.0; binding only to the loopback address will cause health checks to fail
- 5
Third-party assets such as demo images, fonts, and icons must be checked separately under their respective licenses
License & source material
Usage conditions & limitations
Free to use · keep license noticeThis entry covers the free version under the MIT license in the public repository; the free scope applies to that version's code and does not imply that external services or third-party assets are free.
Must comply with when using
- Free use, modification, commercial use, and distribution of this version's code are permitted.
- When distributing copies or substantial portions of the code, retain the original author's copyright notice and the full MIT license notice.
- The code is provided as is; warranties and limitations of liability are governed by the original license and applicable law.
Additional costs & items to verify
- Deployment depends on the velixir platform and its CLI tool; you need to create an account on velixir and use its services; local running is not subject to this limitation.
- Dependency installation and image building are performed server-side by the velixir platform, so the full deployment process requires that external platform service rather than being purely local self-hosting.
- Demo images, fonts, icons, and other third-party assets must be checked under their respective licenses and cannot be judged solely by the code's MIT license.
- External services such as domains, hosting, databases, payments, or AI may incur additional charges.

How this score is calculated
Our heuristic uses license records (up to 30), a demo link (12), a preview (10), stars (15), recorded maintenance (15), description completeness (8), feature records (5) and classification data (5). It is not a code, security or performance test, or a Google score. A link does not establish tested functionality.

A demo link is listed. Check it with your own content and viewport sizes; its presence does not confirm that forms, authentication or payments work.
The catalog identifies Flask as the primary stack. Check the actual dependency manifest and lockfile for versions and hosting requirements. These notes use recorded metadata, not a code audit or a deployment test.

Source file / repository# Python starter [](https://velixir.net/new?template=python-flask) Flask for the routing, gunicorn as the production server, and a `Procfile` telling the platform how to start it. The shape almost every Python service ends up in, minus the parts you would delete anyway. [Deploy it on velixir](https://velixir.net/new?template=python-flask). ## Running it locally ```bash pip install -r requirements.txt python main.py ``` Then open http://localhost:8080. ## Deploying ```bash velixir deploy ``` velixir installs your requirements and builds the image server-side. ## The two rules - **The `Procfile` matters.** Without it the platform starts Flask's development server, which is single-threaded and warns loudly. `gunicorn` is what should serve real traffic. - **Bind `$PORT` on `0.0.0.0`.** velixir injects `PORT`; a loopback-only bind builds fine and then fails its health check. ## Licence MIT.
