Is it possible to place a script on hosting that will run automatically and execute a certain algorithm on other sites?

Question

PHP

Hello.

On one site, you need to do a certain algorithm:

1. Log in (sometimes through a proxy).
2. Press a specific button.
3. Sometimes captcha waters (integration with services for solving it).

Something like iMacrosa under Firefox, only remotely and without participation in initiation.

Question: Is it possible to do this with a regular shared hosting and a script that runs automatically according to a schedule. What language can be suitable for such tasks, if it is feasible.

Thank you.

Answer 1

Logic in any language. Autorun .. Well, for example, through cron. Or a task scheduler. Or any other tool.

Answer 2

You can, of course, hosting generally does not limit which scripts you upload, except perhaps a memory limit

Answer 3

1. You will need a VPS, not just shared hosting for simple sites. VPS now costs almost the same as shared hosting, only much more convenient.
2. Since you will probably need to work with a more or less complete browser, you should look towards https://github.com/GoogleChrome/puppeteer and JavaScript as a language.
