While we think that the Apify platform is super cool, and you should definitely try thefree account, Apify SDK is and will always be open source,runnable locally or on any cloud infrastructure.
Note that we do not test Apify SDK in other cloud environments such as Lambda or on specificarchitectures such as Raspberry PI. We strive to make it work, but there's no guarantee.
Logging into Apify platform from Apify SDK
To access your Apify account from the SDK, you must providecredentials - your API token. You can do thateither by utilizing Apify CLI or by environmentvariables.
Once you provide credentials to your scraper, you will be able to use all the Apify platformfeatures of the SDK, such as calling Actors, saving to cloud storages, using Apify proxies,setting up webhooks and so on.
Log in with CLI
Apify CLI allows you to log in to your Apify account on your computer. If you then run yourscraper using the CLI, your credentials will automatically be added.
In your project folder:
Log in with environment variables
If you prefer not to use Apify CLI, you can always provide credentials to your scraperby setting the APIFY_TOKEN environmentvariable to your API token.
There's also the APIFY_PROXY_PASSWORDenvironment variable. It is automatically inferred from your token by the SDK, but it can be usefulwhen you need to access proxies from a different account than your token represents.
What is an Actor
When you deploy your script to the Apify platform, it becomes an actor.Actor is a serverless microservice that accepts an input and produces an output. It can run fora few seconds, hours or even infinitely. An actor can perform anything from a simple action suchas filling out a web form or sending an email, to complex operations such as crawling an entire websiteand removing duplicates from a large dataset.
Actors can be shared in the Apify Store so that other people can use them.But don't worry, if you share your actor in the store and somebody uses it, it runs under their account,not yours.
