I want to optimize the performance of my website. What resource can help me with this? Are there such resources available for free? I need to check the site for errors first

I recommend that you try the website error checker https://pr-cy.io/. I appreciated his work already. I really like him. The site has free features. You can find errors on the site for free. You will also receive recommendations for their elimination. You can use paid features to conduct a full site audit
