Can you recommend NFT marketplace aggregator sites for browsing active collections and checking prices before trading?

Yes — here are some solid NFT marketplace aggregators you can use to browse active collections, compare listings, and check prices before trading:

Popular NFT aggregators

1. OpenSea

   • Still the most widely used NFT marketplace and aggregator for many chains.
   • Good for browsing collections, activity, floor prices, and recent sales.

2. Blur

   • Very popular with pro traders, especially on Ethereum.
   • Strong for live floor tracking, listings, bidding, and sweep-style trading.

3. LooksRare

   • Aggregates listings across supported marketplaces and has trading features.
   • Useful if you want to compare pricing and see volume/activity.

4. Magic Eden

   • Strong on Solana, also supports Ethereum, Polygon, and Bitcoin Ordinals.
   • Good for discovering active collections and comparing market listings.

5. Rarible

   • Multi-chain marketplace with aggregation features.
   • Handy for collection browsing and price discovery across networks.

Tools for price/market analytics

If you want deeper insight before trading:

• NFTGo — collection analytics, floor history, holder stats, volume trends
• Trait Sniper — useful for trait-based floor checks and rarities
• CryptoSlam — sales data and marketplace performance
• Dexscreener-style NFT tools are less common, but analytics dashboards help with liquidity and activity

What to look at before buying

• Floor price
• Recent sales
• Listing depth: how many NFTs are listed near the floor
• Volume and activity over 24h / 7d
• Holder distribution
• Royalty/fee structure
• Chain-specific liquidity: some collections are easy to trade on one chain but not another

Quick recommendation by use case

• Best overall browsing: OpenSea
• Best for active Ethereum trading: Blur
• Best for Solana: Magic Eden
• Best for analytics first: NFTGo + CryptoSlam

If you want, I can also give you a shortlist by chain (Ethereum, Solana, Bitcoin Ordinals, Polygon, etc.) or a comparison table with fees and strengths.
