Can someone suggest free tech guest post site list?

I need some free high DA/PA tech guest post site list.

No one is going to give away sites they worked hard to scrape. You will have to do your own homework. Start using the regular search queries and look for ones that accept guest posts. Prep your email and also keep your wallet ready because it's gonna be real expensive.

1.look at the freebie giveaway section. some seller will give free backlinks
2.you can get free links in FB free guest post groups
