TraitSniper was built for fast rarity reveals on new NFT collections, plus a free Chrome extension that added data to OpenSea. The extension listing says it tracks floor prices for all collections, ranks collections, lets you snipe rare listings from the activity page, offers quick buy with adjustable gas and calculates your OpenSea portfolio value. The site still advertises a rarity ranking API that it says you can start for free.
Bottom line: Be careful. A tool with no updates since 2023 that now asks you to connect a wallet for an airdrop is a reason to stop and check. Never connect a wallet that holds valuable assets to a site you cannot verify. For rarity data today, use one of the alternatives below.

Whether the extension still works with OpenSea today
We cannot verify it. The site promotes a meme token and an "airdrop" and has a Connect Wallet button, but gives no readable details. Do not sign wallet transactions you do not understand.
Is TraitSniper free?
The extension is listed as free. The site also says you can start its ranking API for free. We found no other published prices.
What did TraitSniper do?

Not that we can see. The Chrome Web Store shows version 1.3.23, last updated on 11 Aug 2023.
