Any free SEO tool for global keyword research and checking their CPC?

Seo tools can be expensive. I use free tools (keyword.io, surfer seo chrome extension, and google search engine autofill) and doing great so far. However, I wanted to save time and effort by using a keyword research tool which shows suggested keywords along with the CPC. I know there are tons of them but if there's any free with no limitations please let me know.
